The SMS uses all safety-based violations recorded during roadside inspections to evaluate safety. A list of these violations can be found in Appendix A of the SMS Methodology document. All of the violations in Appendix A count against the motor carrier. A subset of these violations is applied to evaluate driver safety in cases where the commercial motor vehicle driver is also responsible in part for the occurrence. This subset of violations is noted in the “Driver Responsible” column in Appendix A of the Carrier SMS Methodology document, and is also noted in Appendix A of the Driver SMS Methodology document.
At present, only enforcement personnel who are conducting motor carrier investigations use the driver safety assessment tool in the SMS. The new tool enables Safety Investigators to focus on drivers with poor safety performance histories when they are investigating a motor carrier.
SMS evaluates the safety of individual motor carriers by considering all safety-based roadside inspection violations, not just out-of service violations, as well as State-reported crashes, using 24 months of performance data. SMS assesses motor carriers' safety performance in each of the seven Behavior Analysis and Safety Improvement Categories (BASICs): Unsafe Driving, Hours-of-Service Compliance, Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Hazardous Materials Compliance, and Crash Indicator.
SMS calculates a measure for each BASIC by combining the time and severity weighted violations/crashes (more recent violations are weighted more heavily), normalized by exposure, which is a statistical calculation that allows SMS to make a fair comparison between carriers with different levels of activity (e.g., a hybrid of the number of Power Units per Vehicle Miles Traveled or the number of relevant inspections). The SMS converts each carrier's BASIC measures into percentiles based on rank relative to carriers with similar safety event groupings (i.e., number of relevant inspections, number of inspections with violations, or number of crashes).
The SMS is updated monthly, taking a snapshot of data on the third or last Friday of each month, and takes approximately 10 business days to process and validate the data before it is uploaded on the website. These dates are estimates and are subject to change; if there are problems with the validation, the process could take longer than expected.
To understand more about the BASICS, review the SMS factsheet and briefings on the Compliance, Safety, Accountability Website. For even more detail, review the SMS Methodology document. The document outlines which values are assigned for each violation and how they are weighted in Appendix A, starting on page A-4 in the SMS Methodology document.
The SMS uses segmentation within the Unsafe Driving and Crash Indicator Behavior Analysis and Safety Improvement Categories (BASICs) to account for carrier differences by placing the carrier population into two groups based on the types of vehicles operated. Carriers are grouped by the following two vehicle types/operations:
The segmentation of motor carriers means that companies who have fundamentally different types of vehicles/operations are not compared to each other.
For a detailed description and examples of the safety event groupings by and for each BASIC, please refer to the SMS Methodology document.
One of the ways the SMS accounts for the differences between motor carriers and their operations is by placing carriers in safety event groups based on the number of safety events (e.g., inspections, crashes) in which the carriers have been involved. However, the Federal Motor Carrier Safety Administration’s foremost concern is safety and it accomplishes this by addressing the carriers who pose the greatest crash risk, irrespective of their industry segment.
Safety event groups enable the SMS to deal with the widely diverse motor carrier population, while ensuring that similarly situated carriers are treated with the same standards. Safety event groups do not compare carriers by the commodities they haul or their industry segment.
The tables below outline the safety event groups for each of the Behavior Analysis and Safety Improvement Categories (BASICs) and can be found in the SMS Methodology document.
Hours-of-Service (HOS) Compliance, Driver Fitness, and Vehicle Maintenance BASICs
| Safety Event Group Category | Number of Relevant Inspections* |
| 1 | 3-10 (HOS Compliance) 5-10 (Fitness, Vehicle) |
| 2 | 11-20 |
| 3 | 21-100 |
| 4 | 101-500 |
| 5 | 501+ |
Hazardous Materials Compliance BASIC
| Safety Event Group Category | Number of Relevant Inspections* |
| 1 | 5-10 |
| 2 | 11-15 |
| 3 | 16-40 |
| 4 | 41-100 |
| 5 | 101+ |
*A relevant inspection is one where the roadside inspector reviewed a particular area for evidence of violations (not all inspection types/levels look at all areas).
Controlled Substances/Alcohol BASIC
| Safety Event Group Category | Number of Inspections with Controlled Substances/Alcohol Violations |
| 1 | 1 |
| 2 | 2 |
| 3 | 3 |
| 4 | 4+ |
The Unsafe Driving and Crash Indicator BASICs divide the safety event groups further into two additional categories: combo and straight segments. The following is used under the SMS to determine the carrier's segment:
Unsafe Driving BASIC
| Safety Event Group Category | Combo Segment: Number of Inspections with Unsafe Driving Violations | Straight Segment: Number of Inspections with Unsafe Driving Violations |
| 1 | 3-8 | 3-4 |
| 2 | 9-21 | 5-8 |
| 3 | 22-57 | 9-18 |
| 4 | 58-149 | 19-49 |
| 5 | 150+ | 50+ |
Crash Indicator BASIC
| Safety Event Group Category | Combo Segment: Number of Crashes | Straight Segment: Number of Crashes |
| 1 | 2-3 | 2 |
| 2 | 4-6 | 3-4 |
| 3 | 7-16 | 5-8 |
| 4 | 17-45 | 9-26 |
| 5 | 46+ | 27+ |
There are several websites where a motor carrier can find additional information on FMCSA and the CSA program. Specific links are highlighted below:
FMCSA
CSA
Safety Measurement System (SMS)
CSA Information for Drivers
PUs are recorded in the motor carrier registration data (MCS-150) on file. PUs may include vehicle types such as trucks, tractors, hazardous material tank trucks, motor coaches, and school buses.
The number of PUs a carrier has is used in part to account for each motor carrier's level of on-road exposure when calculating the Unsafe Driving and Crash Indicator Behavior Analysis and Safety Improvement Categories (BASICs). SMS calculates the average number of PUs for each carrier by using (1) the carrier's current number of PUs, plus (2) the number of PUs the carrier had 6 months ago, plus (3) the number of PUs the carrier had 18 months ago divided by 3. The average PUs numbers along with annual Vehicle Miles Traveled information are used as a measure of exposure to estimate the number of PUs operated over a 24-month time period when traffic enforcement violations (used in the Unsafe Driving BASIC measure) or reportable crashes (used in the Crash Indicator) could have occurred. Due to the potentially significant changes in exposure of individual carriers over the course of 24 months (via downsizing, mergers, etc.), an average number of PUs provides a more accurate estimate of vehicle exposure for carriers that have updated their MCS-150 motor carrier registration information.
Please refer to the SMS Methodology document for additional information and an example of the average PU calculation.
The Federal Motor Carrier Safety Administration (FMCSA) regulates all carriers throughout North America that haul loads over 10,000 lbs. and travel interstate. FMCSA also regulates carriers that haul hazardous materials intrastate. These are the carriers that are included in the SMS.
SMS gets a monthly snapshot of data from the Federal Motor Carrier Safety Administration (FMCSA) national database, the Motor Carrier Management Information System (MCMIS). SMS pulls the previous 24 months of roadside inspection data from MCMIS and State-reported commercial motor vehicle crashes and motor carrier registration/Census data and results from Federal and State investigations conducted within the previous 12 months.
SMS results are updated monthly. A snapshot of the data is taken on the third or last Friday of each month and then it takes approximately 10 days to process and validate the data. Once validated, the results are uploaded to the SMS Website. The table below lists a tentative schedule for future releases of SMS results:
| Release Month | Data Snapshot Date | Approximate Release Date |
| June 2026 (early) | Friday, 5/15/26 | Week of 5/25/26 |
| July 2026 | Friday, 6/26/26 | Week of 7/6/26 |
| August 2026 | Friday, 7/31/26 | Week of 8/10/26 |
| September 2026 | Friday, 8/28/26 | Week of 9/7/26 |
| October 2026 | Friday, 9/25/26 | Week of 10/5/26 |
| November 2026 | Friday, 10/30/26 | Week of 11/9/26 |
FMCSA does not, at this time, plan to weight inspection and crash data on a regional basis. FMCSA is committed to realizing reasonable uniformity in State reporting and coding for inspections and crashes.
Roadside inspection reports contain all specific 392.2 local laws cited, but the Safety Measurement System (SMS) uses only 392.2 violations that translate with a specific letter suffix (i.e., 392.2C, 392.2S). If the violation is a 392.2 (with no letter suffix), then the SMS does not use it. If it has a suffix and it is not listed in the table below, the SMS does not use it.
| Section | Violation Description Shown on Roadside Inspection | Severity Weight |
|---|---|---|
| Unsafe Driving BASIC: | ||
| 392.2C | Failure to obey traffic control device | 5 |
| 392.2DH | Headlamps - Failing to dim when required | 3 |

Violations are impacted by time severity; that is, more recent violations are weighted more heavily. Violations that occurred within the last six months count three times, violations that occurred between six months and a year ago count twice, and violations between one and two years old count only once. After two years, violations do not count at all in the Safety Measurement System.
Motor carriers are held accountable for driver errors because they are responsible for the job performance of those who work for them. This is a longstanding Federal Motor Carrier Safety Administration position and is not unique to Compliance, Safety, Accountability or the new SMS.
Carriers are evaluated only on inspections and crashes associated with their own U.S. DOT Number, so only violations that a driver receives while working for a motor carrier apply to that carrier's SMS evaluation. Therefore, the driver's violation history before the driver is hired and after the driver's employment is terminated will not impact a motor carrier's SMS results. However, even if a motor carrier terminates a driver, all of the driver's crashes and inspection results that he or she received while operating for that carrier still apply to the carrier's SMS evaluation for 24 months from the date of occurrence. Because the data is time-weighted, the effect of those occurrences on the motor carrier's percentile rank will diminish over the course of the 24 months.
The SMS evaluates the safety of individual motor carriers by considering all safety-based roadside inspection violations, not just out-of service violations, as well as State-reported crashes, using 24 months of performance data.
When enforcement discovers a driver breaking the law, the officer has several ways to impact the driver and the carrier he/she is representing. It is important to understand each of these ways, how each way impacts the carrier and driver, and how to remove each from your record. Enforcement can issue a citation or warning to a driver for breaking a State law. Citations can be defended in State court. Cases that are lost, or where the plaintiff pleads guilty, are called convictions. Convictions will impact the driver and could show up on the driver’s Commercial Driver’s License and Moving Violation Record.
In addition, enforcement can give a violation on a roadside inspection report. These violations will appear in a driver’s Pre-Employment Screening Program record and could show up in the carrier’s Safety Measurement System (SMS) data. To know which violations are used in SMS, see Table A of the SMS Methodology located here: https://csa.fmcsa.dot.gov/Documents/SMSMethodology.pdf. Carriers and drivers can try to remove incorrect roadside inspection data from their record using DataQs (https://dataqs.fmcsa.dot.gov/). It is possible that a driver can receive a warning or citation with a roadside violation for the same incident. If the carrier or driver wants to protest both of them, they need to do each independently through the aforementioned process. The outcome of one doesn’t necessarily impact the other because each is in a different jurisdiction. Citations are adjudicated in State court, while DataQs is a Federal program.
Under CSA, the data collected at the roadside is more important than ever because it is used in the Safety Measurement System to assess carriers' safety performance. Thus, inspection and crash data that are reported to the Federal Motor Carrier Safety Administration (FMCSA) must meet high standards of uniformity, completeness, accuracy, and timeliness. FMCSA has organized its effort to improve data quality into four core initiatives:
To make our roads safer and sharpen our focus on truck and bus companies that present a high safety risk, FMCSA will regularly make improvements to the Compliance, Safety, Accountability (CSA) program’s SMS. FMCSA announces these changes to the public through the CSA Website and in Federal Register Notices. FMCSA will periodically introduce safety enhancements to the SMS by previewing them, providing educational webinars, and collecting input from motor carriers, enforcement staff, and the public. The Agency designed the SMS expecting that changes would be made as new data and additional analysis became available and that stakeholders and partners would provide their feedback. The Agency continues to collect and analyze input from industry, safety advocates, and other stakeholders to further enhance effectiveness in identifying safety problems before they result in crashes. FMCSA is listening, because together we can save more lives.

There are several components to the SMS calculation. The first thing that needs to be calculated is the measure for each BASIC. The measure has a numerator and denominator. Once the measure is determined, there is a process to convert the measure into a percentile rank.
Numerator of the Measure
The numerator for the measure is the same for all BASICs. This calculation simply involves determining all the violation points, or crash severity points for each BASIC. The first step is totaling all the violation points within each BASIC for each inspection. If any exceed 30, then reduce them to 30 for the inspection for the upcoming calculations.
The second step is to take all the violations that occurred in each BASIC and break them down into three time periods. Using the date of the most recent snapshot (this date can be found on the SMS Website under the “Search for Motor Carrier SMS Monthly Results” text in the search box on the far right of the screen), place the violations into three groups: violations that happened in the last 6 months, violations that happened between 6 months ago and 1 year ago, and violations older than 12 months, but within the last 24 months.
The Federal Motor Carrier Safety Administration (FMCSA) has time weights for inspections. More recent inspections are worth more. For any inspection that happened in the last 6 months, points are multiplied by 3; for any inspection that has happened between 6-12 months, points are multiplied by 2; and, for any inspection that happened more than 1 year ago, but within the last 24 months, points are multiplied by 1.
Next, total all the severity points for each inspection for each BASIC of the three groups. Remember to never exceed 30 points for any inspection per BASIC. Then, multiply the total of that group that occurred within the last 6 months by 3, the total of that group that happened between 6–12 months by 2, and the total of that group that happened more than 1 year ago, but within the last 24 months by 1. Then add those three numbers together and you have the numerator of the measure.
Denominator of the Measure
The denominator of the measure differs depending on which BASIC you are calculating.
For Hours-of-Service (HOS) Compliance, Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, and Hazardous Materials (HM) Compliance BASICs
Total all the inspections for each of the three groups. Then multiply the total of that group that occurred within the last 6 months by 3, the total of that group that has happened between 6-12 months by 2, and the total of that group that happened more than 1 year ago, but within the last 24 months by 1. Then add those three numbers together. This is the denominator of the measure.
Unsafe Driving and Crash Indicator BASICs
There are several parts to this calculation. The first part is calculating the average Power Units (PUs). This is done by taking the carrier’s PU total from 18 months ago, 6 months ago, and today in SMS and adding them together and dividing by 3. Carriers can look up their PU information in the History Section of SMS. Look at the history of the Unsafe Driving or Crash Indicator BASICs.
Next, the Utilization Factor needs to be determined. A carrier needs to determine if they are a straight or compound fleet. If the carrier had 30% or more of their trucks as straight, then they are considered in the straight truck group and, if it is less than that, then they are considered combo. Next, the carrier needs to divide their Vehicle Miles Traveled (VMT) data by their average PU total to determine their VMT per average PU. The VMT they should use is the one currently in SMS. SMS will use the total from the last full year. So, if it is 2011, SMS will use the 2010 data. If the 2010 data is missing, SMS will use the 2009 data. If the 2009 and 2010 are both missing, then SMS assigns the carrier a 1 for the Utilization Factor. Carriers should use the chart that applies to their carrier (i.e., combo or straight) to determine their Utilization Factor. See below.
| VMT per PU for Combo Segment | |
| Combo Segment | |
| VMT per Average PU | Utilization Factor |
| < 80,000 | 1 |
| 80,000 - 160,000 | 1+0.6[(VMT per PU-80,000)/ 80,000] |
| 160,000 - 200,000 | 1.6 |
| > 200,000 | 1 |
| No Recent VMT Information | 1 |
| VMT per Average PU for Straight Segment | |
| Straight Segment | |
| VMT per Average PU | Utilization Factor |
| < 20,000 | 1 |
| 20,000 - 60,000 | VMT per PU/ 20,000 |
| 60,000 - 200,000 | 3 |
| > 200,000 | 1 |
| No Recent VMT Information | 1 |
Next, the average PU is multiplied by the Utilization Factor and this will be your denominator.
Determining Percentile Rank
Now, the carrier divides the denominator into the numerator for each BASIC. This is the carrier’s measure for the BASIC.
The measure is then compared to other carriers’ safety event groups. Safety event groups are explained in this Frequently Asked Question here. The carrier with the highest measure within the safety event group receives a percentile rank of 100 and the one with the lowest measure receives a percentile rank of 0. The rest of the carriers in the safety event group are slotted between those percentile ranks. Carriers cannot calculate their percentile rank on their own because they don’t have other carriers’ safety data. However, there is a place on the SMS Website that gives carriers a measure/percentile rank conversion chart. To view this chart, go to the SMS Website and search for your carrier by placing your U.S. DOT Number in the appropriate search box. Now you should be on your carrier overview page, so select the BASIC that you want to look up. Once on this BASIC page, find and click on the Performance Tools tab on the right side of the screen below the Data Center section. Once you are in this tab, click on Measure View on the far right hand of the screen. The graph that is showing on this page maps measure to percentile rank. The vertical line is for measure and the horizontal line is for percentile rank. The line in the graph shows the correlation between measure and percentile rank for that BASIC and safety event group.
Understanding the following information will help carriers analyze their SMS safety data at a deeper level. Carriers that have a deeper understanding of their SMS data will be able to fix their safety problems more easily. This will improve their SMS percentile ranks in the long run. This document is divided into sections that are aligned with the tabs in the SMS Excel download.
Violation Summary
This tab will be found in all of the SMS Excel downloads for each carrier except the crash file. The main benefit of analyzing the data in this tab is to look at the frequency of violations on three levels. One level is to look at an individual violation by the code and compare to see which violations are the most frequent. Another level is to look at which violations are leading to the most out-of service (OOS) violations. The last and most important analysis of the data in this tab involves grouping violations that are similar. For example, put together all speeding violations or all violations about tires, etc. Next, examine the groups of violations to see which groups of violations come up most frequently. The carrier will have an idea of where to focus after these analyses are done in conjunction with the other sections of the download. The carrier should consider not only the frequency of the violation, but also the severity points for each violation when deciding which violation to focus on. Carriers can look up the severity weights of each violation here: http://csa.fmcsa.dot.gov/Documents/SMS_AppendixA_ViolationsList.xlsx
Acute-Critical Violations
This tab will be found in all of the SMS Excel downloads for each carrier except the crash file. If the carrier has numerous Acute and/or Critical Violations, analysis should be done by grouping similar types of violations. Next, the carrier for each violation and/or each violation type should to try to understand how your safety management contributes to your safety breakdowns. Systematically assess your company’s Safety Management Practices and make improvements where necessary.
Inspections with Violation
This tab will be found in all of the SMS Excel downloads for each carrier except the crash file. This tab has numerous fields, which lend to various types of analysis.
For the inspection section, carriers can analyze their inspection data by date, allowing the carrier to see if trends exist for certain time periods. The carrier should look to see if there are certain periods of time where certain types of violations were more or less present. In addition to looking at the data chronologically, a carrier can look at blocks of time or seasons. Carriers can sort the data by State to see if there are any geographical trends by examining the data at the State by State or regional level. Carriers can also look to see, if applicable, the impact of Hazardous Materials (HM) inspections vs. non-HM materials inspections.
Carriers will want to organize their inspection data by driver. This includes looking at individual drivers, but also grouping drivers by where they are based (if relevant) and type of load(s) they haul (if relevant).
The vehicle section will help carriers see if certain types of trucks are causing more issues than others. This field is particularly useful with the Vehicle Maintenance and HM Compliance Behavior Analysis and Safety Improvement Categories (BASICs).
Viewing the violations, their severity weights, and their impact on OOS can also be a rich data source for carriers. The main benefit is to look at the frequency of violations on many levels. One level is took an individual violations by looking at the code and comparing to see which violations are the most frequent. Another level is to look at which violations are leading to the most OOS violations. Carriers should group violations that are similar; for example, put together all speeding violations or all violations about tires, etc. and then examine which violations come up most frequently. Lastly, carriers should look at the severity weights of the violations as they, along with the frequency, can help the carrier know where to focus. Multiplying the number of times a certain violation occurred with the severity weight can show a carrier how a violation or a group of violations can be impacting a carrier overall.
Crashes
Carriers who have enough crashes can use this Excel file to help identify three types of trends. Carriers can see if their crashes are happening in a certain State or part of the country, which can then lead the carrier into an inquiry of why that is so. The carrier can determine if there are particular drivers who are prone to crashing. If certain individuals are the problem, this will focus the carrier on how to proceed with fixing the problem. Carriers with multiple drivers could look to see if the majority of drivers are coming from a certain location. Lastly, the carriers are given the Vehicle Identification Numbers of trucks and can use this information to determine types of trucks getting into crashes. This might lead to some interesting trends if certain types of vehicles are crashing more frequently than others. The Federal Motor Carrier Safety Administration (FMCSA) lists a lot of crash countermeasures on their website that can assist motor carriers with ways to improve their Crash Indicator BASIC measure.
Other
Carriers should almost always look at each BASIC by itself as the data is most useful when analyzed this way. However, it could be helpful to look at all of the BASICs together when examining how many violations each driver is contributing to the carrier’s safety record.
Additionally, FMCSA has some information in the SMS Information Center that will help carriers improve in each of the BASICs:
The Federal Motor Carrier Safety Administration (FMCSA) has developed a specific mechanism to facilitate data reviews. Requests for data reviews (RDRs) can be made through the DataQs system, an electronic filing system that motor carriers, drivers, and the public use. The first step is to register either at the DataQs website (https://dataqs.fmcsa.dot.gov/), or via the FMCSA Portal. Instructions for filing an RDR are provided, and include simple forms and the submission of information such as the report number, date, and time of the event, State, explanation, and supporting documentation, if needed. Once filed, the RDR and all relevant documentation are routed to the organization responsible for the data, and electronic correspondence is used to communicate with the requestor. The DataQs website is open to the public and offers an online help function to walk users through the process.
Please Note: A carrier can modify registration information (e.g., name, address, or Power Unit data) by updating the MCS-150 form.
Yes. All roadside safety inspection findings count in the SMS, regardless of whether or not the safety inspection report contains violations. Roughly one-third of the 3.5 million inspections that are uploaded to the Federal Motor Carrier Safety Administration's (FMCSA) database each year have zero violations. Safety inspections without regulatory violations serve to improve a motor carrier's evaluation in the SMS.
Carriers and drivers should be aware that not every law enforcement stop is a safety inspection; law enforcement may stop a vehicle to conduct a pre-inspection screening to determine if a vehicle or driver warrants closer examination. A pre-inspection screening may take many forms and may include, but not necessarily be limited to, a cursory check of the vehicle. These cursory checks are commonly confused with a complete safety inspection. If a law enforcement officer conducts only a pre-inspection screening, then a safety inspection report will not be generated. If a driver thinks that a safety inspection has been conducted, FMCSA encourages the driver or motor carrier to ask for a copy of the report to document the safety inspection.
Only pre-existing violations from post-crash inspections are used in the SMS. Violations recorded in the Motor Carrier Management Information System as being attributed to the crash are not used.
No, there is no appeal process for DataQs at this time.
The Safety Measurement System (SMS) calculates a measure for each Behavior Analysis and Safety Improvement Category (BASIC) as described in the SMS Methodology document. The measure is then used to assign a ranking, or percentile, for each motor carrier that has information that could be compared against other similar carriers. This percentile ranking allows the safety behavior of a carrier to be compared with the safety behavior of carriers with similar operations and numbers of safety events.
The percentile is computed on a 0-100 scale, with 100 indicating the worst performance and 0 indicating the best performance. The carrier in the group with the highest measure will be at the 100th percentile, while the carrier with the lowest measure in the group will be at the 0 percentile. All other carriers in the group will be between these two numbers based on their compliance records.
1. Ensure compliance. Take action to address trends and patterns that you find.
Learn more about the safety regulations your company has violated by reviewing the regulations and the corresponding areas in the FMCSRs:
Review FMCSA's educational and technical assistance document, A Motor Carrier's Guide to Improving Highway Safety. This document contains useful information for both drivers and carriers.

2. Understand how your safety management contributes to your safety problems. Systematically assess your company's safety management practices and make improvements where necessary.
It is important for you to consider how safety will be achieved within your organization. Putting this in place begins with developing processes that incorporate safety into every aspect of your operation. Whether you are just starting out, or you have an established company, you should have safety-minded business practices. These will help make sure that you follow Federal regulations. Having these in place can save lives and reduce injuries. They can also improve your company's bottom line by saving time and money on paying fines and responding to regulatory compliance issues. They can also reduce the financial cost of crashes. FMCSA created a tool, the Safety Management Cycle (SMC) to help with this process. Carriers can download an overview of the SMC here: https://csa.fmcsa.dot.gov/Documents/FMC_CSA_12_002_SMC_Overview.pdf and download a list of safety improvement practices that help resolve typical carrier process breakdowns related to each of the BASICs here: https://csa.fmcsa.dot.gov/HelpCenter/Resources.aspx?type=topic&vID=44546. To help identify areas that are causing your safety breakdowns, use the SMC and ask yourself these questions:
POLICIES AND PROCEDURES — Operational rules and processes for a motor carrier and its employees.
ROLES AND RESPONSIBILITIES — Expectations and assignment of duties for a motor carrier and its employees.
QUALIFICATIONS AND HIRING — Finding and qualifying people for the defined roles and responsibilities.
Hiring
Qualifications
TRAINING AND COMMUNICATION — Ongoing process to ensure that a motor carrier and its employees have the proper skills and knowledge to complete their jobs.
Training
Communication
MONITORING AND TRACKING — Ensuring that a motor carrier and its employees are in compliance with policies and procedures and roles and responsibilities.
MEANINGFUL ACTION — Providing positive reinforcement for, or aiming at improving or correcting, employee behavior.
3. Check and update your MCS-150 carrier registration information.
4. Review your inspection and crash reports data and request corrections as needed. Review your reports through the SMS Website.
5. Educate yourself and your employees! Visit the Compliance, Safety, Accountability (CSA) Website to learn more about CSA.
Those motor carriers that want multiple employees to access their Safety Measurement System (SMS) data can do so using a Federal Motor Carrier Safety Administration (FMCSA) Portal account. Motor carrier Portal accounts contain a link to the SMS data. To set up an FMCSA Portal account, do the following:
For additional assistance with FMCSA Portal accounts, please call the Help Desk at 800-832-5660.
The Federal Motor Carrier Safety Administration uses the SMS to:
The Summary of Activities presents the most recent investigation and the number of roadside inspections and crashes that have occurred during the 24-month timeframe that are used to calculate the Safety Measurement System (SMS) results for the motor carrier.
The Total Inspections count consists of all roadside inspections (Levels I through VI). The inspection total is broken down into total inspections without violations used in the SMS and total inspections with violations used in the SMS.
The Total Crashes count consists of all the Federal Motor Carrier Safety Administration-reportable crashes. Reportable crashes include crashes that resulted in an injury or fatality to a person involved in the crash and crashes that required at least one vehicle to be towed from the scene due to disabling damage where there were no injuries or fatalities.
Selecting “Continue for more Crash, Inspection & Investigation Details” reveals more information about recent investigations, inspections, and crashes. The five most recent investigations and when they occurred are listed. Inspections are broken down by type (i.e., driver, vehicle, and placardable Hazardous Materials (HM)) and include out-of-service (OOS) percentile rates.
The Driver Inspection count consists of all Level I, II, III, and VI inspections. The driver OOS rate is calculated as the number of driver inspections with at least one driver OOS violation divided by the total number of driver inspections.
The Vehicle Inspection count consists of all Level I, II, V, and VI inspections. The vehicle OOS rate is calculated as the number of vehicle inspections with at least one vehicle OOS violation divided by the total number of vehicle inspections.
The Placardable HM Inspection count consists of all vehicle inspections (Level I, II, V, and VI) where placardable quantities of HM are present. The HM OOS rate is calculated as the number of placardable HM vehicle inspections with at least one HM OOS violation divided by the total number of placardable HM vehicle inspections.
Total Crashes is broken down into three categories: Fatal, Injury, and Towaway.
The major sections displayed in the Safety Measurement System (SMS) for the selected motor carrier include the following:
Each BASIC's details page, except where noted, consists of five parts:
symbol, based on the data, indicates that the Federal Motor Carrier Safety Administration may prioritize a motor carrier for further monitoring, and the reason (roadside and/or investigation results).Carrier safety performance in the SMS is based upon the previous 24 months of on-road performance, inspection and crash data, and Acute and Critical Violations found during investigations over the last 12 months. Either on-road performance or investigation results can result in a carrier being identified for intervention.
The SMS will stop identifying motor carriers for intervention when their Behavior Analysis and Safety Improvement Category (BASIC) percentile ranks are no longer above the Intervention Thresholds. There are three ways that this can happen:
The SMS will stop flagging motor carriers based on Acute and Critical Violations one year after the Acute/Critical Violation was issued. Keep in mind that the SMS updates monthly, so this change will be reflected on the next SMS update after the one year timeframe has passed.
Understanding the regulations and ensuring vehicles and drivers are safe today will help keep carriers off of the Federal Motor Carrier Safety Administration's radar tomorrow.
The Federal Motor Carrier Safety Administration (FMCSA) includes investigation findings (e.g., what FMCSA or State Partners find during a motor carrier investigation) when assessing Behavior Analysis and Safety Improvement Category (BASIC) performance. The Investigation Results Details tab provided in the Safety Measurement System Website displays an “Acute/Critical Violation Found” icon when an investigation conducted within the previous 12 months resulted in the discovery of Acute and/or Critical Violations within a BASIC. Acute and Critical Violations are defined below.
Acute Violations
Critical Violations
The “Acute/Critical Violation Found” icon will be displayed in the carrier's Investigation Results for the BASIC for 12 months following the date of the investigation. Select this link to view the list of Acute and Critical Violations.
FMCSA is committed to continually evolving and enhancing the SMS in response to new data, stakeholder feedback, and analyses to make our roads safer for everyone. That is why we propose enhancements to the SMS that put our SMS Effectiveness Test (ET) and stakeholder input to work to more effectively prioritize those motor carriers that pose the greatest safety risk for interventions. These proposed enhancements to the SMS would allow us to sharpen our focus on carriers with high crash rates, prioritize our investigative resources on carriers with more crash involvement, more accurately account for the carriers that possess increased exposure due to above average Vehicle Miles Travelled (VMT), and strengthen Hazardous Materials (HM) compliance. Results from our SMS ET show that these proposed changes would identify carriers for prioritization that have a crash rate 8 percent higher than those identified by the current methodology (from 4.82 to 5.21 crashes per 100 Power Units (PUs)).
To learn more about these proposed enhancements, review the Foundational Document. You can also visit the SMS Preview Homepage to tour each of the proposed enhancements.
The structure of the new SMS is such that the motor carrier’s role in the crash (i.e. preventability) is not automatically determined or considered. In fact, recordable crash reports that States submit to the Federal Motor Carrier Safety Administration (FMCSA) do not include the motor carrier’s role in the crash. Consequently, motor carriers are identified for possible intervention based on recordable crashes without consideration of the motor carrier’s role.
This approach is taken because data analysis has historically shown that motor carriers who are involved in crashes, regardless of the motor carrier’s role, are likely to be involved in more future crashes than carriers who are not. Put simply, past crashes are a good predictor of future crashes.
However, as of August 1, 2017, FMCSA is conducting a 24-month Crash Preventability Demonstration Program to review the preventability of certain crash types. Throughout the Demonstration Program, FMCSA will maintain data so that at the program’s conclusion, the Agency can conduct analyses to include: the cost of operating the test and its extrapolation to a larger program; future crash rates of carriers that submitted RDRs; future crash rates of motor carriers with Not Preventable crashes; and impacts to the SMS Crash Indicator BASIC and prioritization. The analysis will be used to examine industry assertions that crashes of these types are not preventable and that removing these crashes from motor carriers’ records would result in a better correlation to future crash risk, as well as to inform future policy decisions on this issue. Details about the program can be found here: https://fmcsa.dot.gov/safety/crash-preventability-demonstration-program
CSA is the Federal Motor Carrier Safety Administration's (FMCSA) safety compliance and enforcement program, which holds motor carriers and drivers accountable for their safety on our Nation’s roads. CSA affects carriers subject to the Federal Motor Carrier Safety Regulations, carriers transporting passengers or cargo in interstate commerce, and Hazardous Materials carriers operating in intrastate commerce. CSA may also impact carriers whose State requires that they obtain a U.S. DOT Number. CSA consists of three key components:
The new SMS data updates once a month. A snapshot of the data is taken on the third or last Friday of each month, and it takes approximately 10 days to process and validate the data before it is updated on the website. The snapshot date is located above the summary of the Behavior Analysis Safety Improvement Category percentile ranks in the SMS. The likely reason that your MCS-150 data is not up-to-date in SMS is that you made the change after the date of the snapshot.
To comment on these proposed enhancements, visit the Federal Register Notice.
All of the reference materials for the Q&A sessions are available on the Resources page of the Help Center. Once there, you can review the video presentation, as well as the slides and transcript of that presentation. You can also access the video here and the transcript here.
The Utilization Factor accounts for the motor carriers that possess increased exposure due to above average Vehicle Miles Travelled (VMT). These carriers are also referred to as high-utilization carriers. We propose adjusting their average Power Unit (PU) values when calculating measures in the Unsafe Driving and Crash Indicator Behavior Analysis and Safety Improvement Categories (BASICs). Carriers with higher Utilization Factors would see a reduction in their measures for the Unsafe Driving and Crash Indicator BASICs.
Industry stakeholders noted that the current limit for the Utilization Factor of 200,000 VMT per average PU does not accurately reflect the increased exposure of these carriers. FMCSA proposes expanding the range over which the Utilization Factor is applied from 200,000 to 250,000 VMT per average PU to more accurately account for these carriers.
To learn more about this proposed change, review the Foundational Document. You can also Tour this Change to see this proposed enhancement in action.
FMCSA proposes an enhancement to sharpen our focus on motor carriers with recent violations. We propose to simplify our data sufficiency standards by only assigning Behavior Analysis and Safety Improvement Category (BASIC) percentiles to carriers that have had an inspection with a violation in the past year. Currently, we assign percentiles in the Hours-of-Service (HOS) Compliance, Vehicle Maintenance, Hazardous Materials (HM) Compliance, and Driver Fitness BASICs to carriers that meet the following criteria: the most recent inspection from the past two years resulted in a violation.
To learn more about this proposed change, review the Foundational Document. You can also Tour this Change to see this proposed enhancement in action.
A Hazardous Materials (HM) placardable vehicle inspection is classified as a cargo tank inspection if the carrier’s cargo tank type on its inspection report is MC 300 Series, DOT 400 Series, or Other. All other HM placardable inspections are classified as non-cargo tank inspections.
FMCSA proposes an enhancement to the Hazardous Materials (HM) Compliance Behavior Analysis and Safety Improvement Category (BASIC) to make it more effective at identifying motor carriers with HM compliance problems for interventions. This enhancement includes:
To learn more about this proposed change, review the Foundational Document. You can also Tour this Change to see this proposed enhancement in action.
FMCSA is holding four Q&A sessions for the public, where you will be able to ask questions about the proposed enhancements and receive real-time responses. The schedule for the sessions is provided below.
Before the Q&A sessions, you can view a video presentation on the proposed changes and how to use the preview site. You can also review slides and a transcript of that presentation. All of these materials are available on the Resources page in the Help Center. Then simply join in online for a Q&A session of your choice. Each session will end once all questions have been answered. We encourage you to submit questions before the Q&A sessions via the CSA Feedback form.
Register for one of the sessions via the here.
Carriers can view their own safety data by logging in to the SMS Website. This is the SMS Preview site where carriers can see how the proposed enhancements may impact their SMS results.
During the public preview, carriers can see how the proposed enhancements may impact their own SMS results. The public can see the impact of the proposed changes by viewing example carriers and touring each proposed enhancement.
Go to the SMS Preview Homepage, and select a proposed enhancement to take a tour of that change. You can also explore each change on your own. Just hover over the blue flags for detailed information about each proposed change.
Click on Get Started here in the Help Center to learn what you can do on the SMS Preview site, from touring each proposed enhancement to submitting comments after your tour.
During the public preview, carriers can log in on the SMS Preview Homepage or via the CSA Outreach link in the Portal using their U.S. DOT Number and PIN. Once logged in, carriers can see how the proposed enhancements may impact their own SMS results.
To access the SMS Preview Website, log into the Portal and select the CSA Outreach link. If you are logged in to the CSA Website, you can also select an SMS Preview link.
We updated the results of our SMS Effectiveness Test (ET) to reflect these proposed enhancements in two easy-to-read graphs. Select “How does the SMS relate to crashes?” to view these graphs, or click here.
An operating while out-of-service (OOS) violation occurs when a driver continues to operate after receiving an OOS Order without correcting the OOS condition. Currently, FMCSA categorizes operating while OOS violations under the same Behavior Analysis and Safety Improvement Category (BASIC) as the initial OOS violation. To more effectively identify driver safety problems related to OOS, FMCSA proposes moving operating while OOS violations to the Unsafe Driving BASIC. This proposed change would consolidate driver safety problems that are currently spread across multiple BASICs.
To learn more about this proposed change, review the Foundational Document. You can also Tour this Change to see this proposed enhancement in action.
Motor carriers are prioritized for interventions if their Behavior Analysis and Safety Improvement Categories (BASICs) are at or above Intervention Thresholds. Industry stakeholders maintain that some of the Intervention Thresholds are ineffective because their BASICs are not highly correlated to crash risk. FMCSA proposes an enhancement to the Intervention Thresholds for the Vehicle Maintenance, Controlled Substances/Alcohol, and Driver Fitness BASICs to more closely reflect these BASICs’ correlation to crash risk and improve our focus on carriers with high crash rates. This enhancement includes:
To learn more about this proposed change, review the Foundational Document. You can also Tour this Change to see this proposed enhancement in action.
FMCSA is proposing these changes to gather input and comments from the public and the industry to further inform the Correlation Study being conducted by the National Academies of Sciences. The proposed changes, if adopted, will not be implemented until after FMCSA receives any recommendations from the study and identifies any necessary corrective actions. In the meantime, the comments and analysis will be provided for consideration in the study.
FMCSA proposes an enhancement to the crash data sufficiency standards to focus our investigative resources on carriers with more crash involvement. We propose increasing the number of crashes required to assign carriers a percentile in the Crash Indicator Behavior Analysis and Safety Improvement Category (BASIC) from two to three. Currently, we assign percentiles in this BASIC if carriers have had at least two reportable crashes in the past two years.
To learn more about this proposed change, review the Foundational Document. You can also Tour this Change to see this proposed enhancement in action.
Users can view motor carriers' SMS data here. Part of the website is open to the public and requires no password. The open part of the website includes each motor carrier's Behavior Analysis and Safety Improvement Category (BASIC) percentile ranks for five of the seven BASICs: Unsafe Driving, Hours-of-Service (HOS) Compliance BASIC, Controlled Substances/Alcohol, Driver Fitness, and Vehicle Maintenance. The website also includes lists of crashes, roadside inspections, and violations resulting from roadside inspections.
When motor carriers sign in, they will be able to see additional data:
Motor carriers can sign in via the Federal Motor Carrier Safety Administration (FMCSA) Portal or directly through the SMS Website. From this SMS page, a carrier representative can log in with its U.S. DOT Number and PIN in order to access the carrier's non-public data. The carrier sign-in is at the bottom center of the screen. Once signed in, you will be guided back to the SMS homepage. After that, in the search box in the middle right section of the screen, you should type in the U.S. DOT # or MC # and hit search.
Motor carriers can request an FMCSA Portal account by clicking here and following the instructions to request an account. For additional assistance with an FMCSA Portal account, contact the Help Desk at 800-832-5660. To sign in via the SMS Website, you will need your U.S. DOT Number and PIN. Note that a Docket Number PIN will not enable you to see your SMS data. If you cannot locate your PIN or were never assigned one, complete the PIN registration process. A notification letter with your PIN will be generated and mailed to the address that was submitted on your most recent MCS-150 form. You should receive this letter within two weeks. If you need any assistance with PIN issues, call the FMCSA Help Desk at 800-832-5660 during normal business hours.
Motor carriers need a Federal Motor Carrier Safety Administration (FMCSA)-issued U.S. DOT Number and a U.S. DOT PIN (not a Docket PIN) to access the SMS Website. If you are experiencing difficulties, please review the information below before contacting the SMS web team for assistance.
Motor carriers can log in to the SMS by entering their U.S. DOT Number and U.S. DOT PIN on the SMS login page, or signing in to the Federal Motor Carrier Safety Administration (FMCSA) Portal and selecting the SMS link.
You can request a U.S. DOT PIN via https://safer.fmcsa.dot.gov/ and follow the instructions on the page. You can also call 800-832-5660 for assistance.
If you do not know your PIN, then you should request a new U.S. DOT PIN via https://safer.fmcsa.dot.gov/ and follow the instructions on the page. (Note: Entering the Docket PIN will not allow login.)
Access to the SMS login page and to the FMCSA Portal is available on the SMS homepage.
The severity points for all violations used in the SMS can be found in Appendix A of the SMS Methodology and in this MS Excel spreadsheet.
The severity weights reflect the relative importance of each violation within each particular Behavior Analysis and Safety Improvement Category (BASIC). They cannot be compared meaningfully across the various BASICs. For example, a violation with a severity weight of 7 in the Vehicle Maintenance BASIC is not intended to be equivalent to a violation with a severity weight of 7 in the Driver Fitness BASIC. The violation severity weights are currently being reviewed based on feedback from stakeholders.
The ISS is not available to the public. A carrier can access its own ISS value by signing into the Portal or by logging in to the Safety Measurement System Website. A carrier can register on the Portal using its U.S. DOT Number and U.S. DOT PIN. For answers to questions about the Portal, contact compass@dot.gov or call 1-800-832-5660.
FMCSA uses the current safety rating process outlined in 49 CFR Part 385, which determines a carrier’s safety fitness through an Onsite Investigation. Safety rating information is available on the SAFER Website.
There are several steps that carriers can take to successfully navigate the CSA program.
Check, update, and review your records:
Ensure compliance:
Visit the CSA Website:
Pursuant to the FAST Act of 2015, certain property carrier data is in no longer available for public display on the SMS Website. The public can view property carrier data including inspection and crash data, investigation results, and measures for all public Behavior Analysis and Safety Improvement Categories (BASICs). The Crash Indicator and Hazardous Materials (HM) Compliance BASICs remain unavailable to the public. The public can also view all passenger carrier data.
Inspection and crash data that are collected and reported to the Federal Motor Carrier Safety Administration (FMCSA) must meet high standards of uniformity, completeness, accuracy, and timeliness. FMCSA has made significant strides in improving the quality of crash and inspection data by developing a comprehensive program that includes raising the awareness of these standards, developing a means to measure State safety data quality, and working directly with States through either a State onsite review process or direct technical assistance to improve the quality of State safety data.
This means that the carrier’s operating authority is not current for some reason. To find out additional information about this situation there are two things that can be done:
These inspections can be viewed in the Inspection History section for these BASICs on the SMS Website. Inspection History uses three views: the total number of inspections for each carrier, as well as a breakdown of the number of inspections with and without violations.
Stakeholders can also submit feedback through the CSA feedback mechanism located at: http://csa.fmcsa.dot.gov/CSA_Feedback.aspx.
The Federal Motor Carrier Safety Administration does not address drivers the same way that it addresses motor carriers. While motor carriers are prioritized for intervention based on the Safety Measurement System, drivers are only investigated during a carrier investigation. Therefore, no Intervention Thresholds are in place for drivers.
Noncompliant motor carriers may be subject to costly repairs, delays, and penalties, or may be ordered to stay off the road entirely. For additional information, visit the Federal Motor Carrier Safety Administration's “Safety is Good Business – Crashes Hurt Your Bottom Line.”
Higher percentile ranks could cause a motor carrier to enter, or remain, in the pool of carriers with BASICs that exceed the Intervention Thresholds. Carriers with percentiles above a certain Intervention Threshold and meeting minimum data sufficiency requirements in a BASIC can be deemed poor safety performers. These carriers will be prioritized for Compliance, Safety, Accountability interventions. Increased percentiles may make a carrier subject to more severe interventions.
The Carrier Registration Information contains a summary of the registration information provided by the motor carrier to the Federal Motor Carrier Administration (FMCSA). This information is current as of the Safety Measurement System (SMS) data snapshot date. If a motor carrier updates its registration information after the SMS data snapshot date, the changes will be reflected in the next monthly SMS results.
The most up-to-date registration information for a motor carrier can be obtained from FMCSA's Safety and Fitness Electronic Records System Website.
Motor carriers are required to update this data at least every two years. Failure to do so will result in the carrier's U.S. DOT Number being inactivated. A message is displayed if the registration data has not been updated within the two-year requirement period.
Instructions for updating motor carrier registration information are displayed by selecting the “Update Registration Info” button.
Selecting the “Carrier Registration Details” button will display additional details of the motor carrier's registration information, including contact information, operation classification, and type of cargo carried.
Recent Investigations lists the five most recent investigations conducted by the Federal Motor Carrier Safety Administration or its State Partners. The listing is not limited to the 24-month timeframe that is used to calculate the Safety Measurement System results for the motor carrier.
There is no current plan to make the Crash Indicator Behavior Analysis and Safety Improvement Category available for public viewing. The Federal Motor Carrier Safety Administration is currently examining crash data to see if weighting can be applied in a cost effective manner. Details about this research can be found here: http://csa.fmcsa.dot.gov/documents/CrashWeightingResearchPlan_7-2012.pdf.
While the Federal Motor Carrier Safety Administration does not use the Safety Measurement System (SMS) or any other system to assign formal safety ratings to individual drivers, the agency recognizes that holding drivers accountable for safe driving behavior is an important part of the safety compliance and enforcement process. Safety Investigators (SIs) always systematically investigate drivers with egregious violations when investigating a motor carrier. Additionally, SIs use the Driver SMS, an internal safety assessment tool, to review drivers with strong patterns of noncompliance. Any violations that are not corrected may result in a Notice of Violation or Notice of Claim for the driver.
The DSMS is a component of the overall Safety Measurement System (SMS). The DSMS is a tool that enables enforcement personnel to assess individual drivers in the Behavior Analysis and Safety Improvement Categories using 36 months of roadside performance data across employers.
State can do that. DSMS does not impact a driver's Commercial Driver's License. Neither drivers nor employing motor carriers nor the general public have access to the DSMS. FMCSA does not address drivers the same way it addresses carriers today, nor will it under the Compliance, Safety, Accountability program. While carriers are prioritized for intervention based on the SMS, drivers are only investigated during a carrier investigation. Therefore, no Intervention Thresholds are in place for drivers.
The SMS categorizes inspections into three types: driver, vehicle, and placardable HM vehicle inspections. The driver inspection examines driver issues and is associated with the following Behavior Analysis and Safety Improvement Categories (BASICs): Unsafe Driving, Hours-of-Service Compliance, Driver Fitness, and Controlled Substances/Alcohol. The vehicle inspection relates to the following BASIC: Vehicle Maintenance. Placardable HM vehicle inspections impact the HM Compliance BASIC. During a roadside inspection, a truck can receive a driver inspection, vehicle inspection, and/or a placardable HM vehicle inspection. The total inspections will not necessarily equal the total of vehicle + driver + hazmat inspections. For example, if an inspector does a Level 1 inspection where he examines the vehicle and the driver, it would show up in the SMS like this:
In other words, drivers and motor carriers can have more than one type of inspection during a single inspection.
When investigating a motor carrier, a Safety Investigator (SI) looks at driver history for egregious violations of the Federal Motor Carrier Safety Regulations (FMCSRs). These violations are sometimes referred to as Red Flag Violations and are always investigated as part of a carrier investigation. The SI conducting the investigation looks to see if the violation has been corrected. At present, there are 16 such violations, though this list may be updated periodically. These violations are outlined in the table below, along with the Behavior Analysis and Safety Improvement Categories (BASICs) to which they correspond.
| BASIC | FMCSR Part | Violation Description |
| Driver Fitness | 383.21 | Operating a commercial motor vehicle (CMV) with more than one driver's license |
| Driver Fitness | 383.23(a)(2) | Operating a CMV without a valid commercial driver's license (CDL) |
| Driver Fitness | 383.51(a) | Driving a CMV (CDL) while disqualified |
| Driver Fitness | 383.51A-SIN | Driving a CMV while CDL is suspended for a safety-related or unknown reason and in the state of driver's license issuance |
| Driver Fitness | 383.51A-SOUT | Driving a CMV while CDL is suspended for safety-related or unknown reason and outside the driver's license state of issuance. |
| Driver Fitness | 383.91(a) | Operating a CMV with improper CDL group |
| Driver Fitness | 391.11 | Unqualified driver |
| Driver Fitness | 391.11(b)(5) | Driver lacking valid license for type of vehicle being operated |
| Driver Fitness | 391.11(b)(7) | Driver disqualified from operating CMV |
| Driver Fitness | 391.15(a) | Driving a CMV while disqualified |
| Driver Fitness | 391.15A-SIN | Driving a CMV while disqualified. Suspended for safety-related or unknown reason and in the state of driver’s license issuance. |
| Driver Fitness | 391.15A-SOUT | Driving a CMV while disqualified. Suspended for a safety-related or unknown reason and outside the driver's license state of issuance. |
| Controlled Substances/Alcohol | 392.4(a) | Driver uses or is in possession of drugs |
| Controlled Substances/Alcohol | 392.5(a) | Possession/use/under influence of alcohol less than 4 hours prior to duty |
| Fatigued Driving (HOS) | 395.13(d) | Driving after being declared out-of-service (OOS) |
| Vehicle Maintenance | 396.9(c)(2) | Operating an OOS vehicle |
Any driver violations identified and addressed during carrier investigations that are not corrected may result in a driver Notice of Violation or Notice of Claim.
The Federal Motor Carrier Safety Administration's A Motor Carrier's Guide to Improving Highway Safety is designed to assist motor carriers in understanding and complying with the Federal Motor Carrier Safety Regulations.
No, the Federal Motor Carrier Safety Administration does not provide a list or otherwise recommend specific safety consultants.
The Federal Motor Carrier Safety Administration (FMCSA) is not certifying anyone's CSA training and is not tracking CSA seminars at the national level. However, the Agency recommends that you contact your local FMCSA Division to see if they are carrying out any training in your State. Their contact information can be found in this list of Field Operations, Service Center, and State-level motor carrier Division offices. You can also contact local trucking professional organizations since they often hold CSA seminars.
In addition, you can educate yourself about CSA by accessing these helpful online informational tools:
Questions about CSA can be answered at the CSA Website through one of three methods:
To request a speaker to address CSA at your organization, contact your State's FMCSA Division office. You can also make speaker requests via the CSA feedback system, which will add your request for a CSA speaker to a list of similar requests. If and when CSA speakers become available, the Agency will contact you. Stakeholders can also call FMCSA Communications at 202-366-9999.
The Federal Motor Carrier Safety Administration does not have a budget for printing and mailing CSA material to the public. However, there are many free downloadable and printable documents available on the CSA Website.
Keep up with the latest information on CSA as it becomes available by signing up for the email subscription service or RSS feed and by periodically reviewing the CSA Website.
Despite rumors to the contrary, no. While research was recently released stating that a driver's BMI is a risk factor for identifying sleep apnea, neither the Federal Motor Carrier Safety Administration (FMCSA) nor the Compliance, Safety, Accountability program currently has any rules that restrict who can be a commercial motor vehicle driver based on BMI or weight, or neck size. For more information view FMCSA’s Spotlight on Sleep Apnea.
The Federal Motor Carrier Safety Administration (FMCSA) uses the safety rating methodology as outlined in 49 CFR Part 385 and will continue to use this methodology until the rulemaking process for the proposed Safety Fitness Determination is completed. Under the current process, a motor carrier will receive an Unsatisfactory safety rating following an Onsite Investigation if FMCSA determines that the carrier's safety management controls fail to meet the safety fitness standard outlined in 49 CFR Part 385.
The Intervention Thresholds for carriers are organized by BASIC and are set based on a given BASIC's relationship to crash risk. The Federal Motor Carrier Safety Administration’s analysis has shown that the strongest relationship to crash risk is found with high percentiles in the Unsafe Driving, Hours-of-Service (HOS) Compliance and Crash Indicator BASICs. Therefore, these higher risk BASICs have a lower threshold for interventions than the other BASICs. Currently, the Intervention Thresholds are as follows:
| BASIC | Intervention Thresholds | ||
| Passenger | HM | General | |
| Unsafe Driving, HOS Compliance, Crash Indicator | ≥50% | ≥60% | ≥65% |
| Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance | ≥65% | ≥75% | ≥80% |
| HM Compliance | ≥80% | ≥80% | ≥80% |
The Federal government does hold the general public accountable for its role in all accidents, including those with trucks. The National Highway Traffic Safety Administration deals with the general motoring public. FMCSA also has a program that deals with aggressive drivers called Ticketing Aggressive Cars and Trucks.
Most FMCSA questions that are unrelated to CSA can be answered either by FMCSA Headquarters at 1-800-832-5660 or by State FMCSA field offices.
CSA does not mandate event/log recorders. However, the Federal Motor Carrier Safety Administration recently issued a new rule about mandating EOBRs for truck and bus companies with serious Hours-of-Service violations.
FMCSA's regulations can be found here. FMCSA’s A Motor Carrier's Guide to Improving Highway Safety is also designed to assist motor carriers in understanding and complying with the Federal Motor Carrier Safety Regulations.

A pre-inspection screening, which takes less time than an actual safety inspection, may take many forms. It may include, but not necessarily be limited to, a cursory check of the vehicle. These cursory checks are commonly confused with a complete safety inspection. If an enforcement officer conducts only a pre-inspection screening, then a safety inspection report will not be generated. It is also important to note that different enforcement jurisdictions may use different methods to select or screen a vehicle for a safety inspection. There are strict criteria regarding what needs to be done for a roadside inspection report to be generated. If the pre-screening doesn't meet those criteria, no report will be generated. Keep in mind that an inspection usually takes a lot longer than a pre-screening and involves much more intense scrutiny of the driver and/or the vehicle. A driver can request an inspection, but it is up to the roadside inspector to determine if he or she will give one or not.
Motor carriers can view an electronic duplicate of all of their inspections through the Safety Measurement System, Federal Motor Carrier Safety Administration Portal, or SAFER. Motor carriers that want a physical copy of inspection reports must contact the State agency where the inspection occurred or enter an inspection report request through the DataQs System.
Although motor carriers have to update their MCS-150 form every two years, motor carriers should understand that this is just the minimum requirement; motor carriers may update their MCS-150 form at any time. The Federal Motor Carrier Safety Administration encourages carriers to update their MCS-150 any time there is a change in their data. Since the Safety Measurement System (SMS) uses VMT and PU data, motor carriers should update their form at least once a year. Motor carriers can update their MCS-150 data here by selecting “I need to update my U.S. DOT Number registration information or file my biennial update” and following the instructions. Instructions for updating your MCS-150 form are available here.
The SMS updates monthly. MCS-150 changes will not appear immediately in the SMS, but changes will likely show up the following month. However, MCS-150 updates should show up more quickly on the Safety and Fitness Electronic Records System Website.
The Federal Motor Carrier Safety Administration (FMCSA) Headquarters sends warning letters to motor carriers. A warning letter notifies a motor carrier that its safety performance data shows a lack of compliance with motor carrier safety regulations. The warning letter lists the Behavior Analysis and Safety Improvement Categories (BASICs) where the carrier’s performance indicates safety issues and encourages the carrier to look at its Safety Measurement System (SMS) data online.
Carriers do not need to respond in writing to FMCSA after receiving a warning letter. FMCSA encourages motor carriers to log in to the SMS to examine their data, focusing their attention first on the BASICs that are over or near the Intervention Threshold. Carriers should also consider doing all of the following:
The Federal Motor Carrier Safety Administration (FMCSA) promotes the electronic collection of inspection data by providing the software and grants for laptops to States. In general, States that are not already collecting inspection data electronically are moving in this direction. To further provide incentives to States, FMCSA has created inspection data performance measures to raise awareness of the relative speed at which States upload inspection reports. In addition, FMCSA has provided online tools to help States diagnose the reasons for any untimely submission of inspection reports. Nearly 95 percent of the over 3 million inspections conducted annually are uploaded to the FMCSA Website within FMCSA's 21-day standard.
No. This set of SMS changes, announced in a Federal Register Notice, focused on the display of information on the SMS Website (outlined in this guidance document) and does not make changes to the methodology itself.
The Trends graph indicates how a motor carrier’s on-road performance measure has fluctuated over time using the current SMS methodology for all of its snapshots. The History graph reflects a motor carrier’s on-road performance measure at each point in time using the version of the SMS methodology that was in use when the snapshot was taken. The new SMS display allows users to view the Trends and History graphs side by side for easier comparison.
All inspection violations that pertain to a Behavior Analysis and Safety Improvement Category (BASIC) are assigned violation weights that reflect their association with crash occurrence and crash consequences. The violation weight helps differentiate the levels of crash risk associated with the various violations attributed to each BASIC. Violation weight is assigned on a 1 -10 scale, where 1 represents the lowest crash risk and 10 represents the highest crash risk relative to the other violations in the BASIC. Also, an additional weight of 2 is applied to violations that result in out-of-service orders.
Crashes are assigned severity weights according to their impact. Greater weight is attributed to crashes involving injuries, fatalities, and/or the release of hazardous materials than to crashes only resulting in a vehicle tow-away.
Because the weights reflect the relative importance of each violation within each particular BASIC, they cannot be compared meaningfully across the various BASICs. The Safety Measurement System (SMS) severity weights are subject to change, so please refer to the SMS Methodology and SMS Methodology Appendix A Violations List for further information.
Any violation or crash that occurred within the previous 24 months of performance data is considered when determining the Behavior Analysis and Safety Improvement Category (BASIC) measure. However, inspections, violations, and crashes are time weighted when they are included in the SMS calculations. Events that have occurred within 6 months of the SMS run date receive the highest time weight (they are multiplied times 3), events greater than 6 months but less than or equal to 12 months are assigned less time weight (they are multiplied times 2), and events that occurred greater than 12 months from the SMS run date are assigned the smallest time weight (they are multiplied times 1). Details are explained in the SMS Methodology document.
One of the ways the Safety Measurement System (SMS) accounts for the differences between carriers and their operations is to place carriers in safety event groups based on the number of safety events (e.g., inspections, crashes) in which the carriers have been involved.
Safety event groups enable SMS to deal with the widely diverse motor carrier population, while ensuring that similarly situated carriers are treated with the same standards. Safety event groups do not compare carriers by the commodities they haul or their industry segment.
For a detailed description and examples of the safety event groups for each Behavior Analysis and Safety Improvement Category, please refer to the SMS Methodology document.
The Carrier Safety Measurement System (SMS) Crash Indicator includes all reportable crashes, regardless of the carrier’s or driver’s role in the crash. FMCSA’s SMS does not weight a crash differently based on the carrier’s or driver’s role, although it does weight crashes based on severity. State-reported crash data are used to calculate the Crash Indicator measure of relative crash involvement. State-reported crash data do not have information regarding fault. The SMS algorithm, by design, ranks carriers in comparison to other carriers. All carriers are treated the same way. In the case of the Crash Indicator measure the carrier’s crash rates are being compared to other carriers’ crash rates regardless of the role of a carrier in these crashes. Therefore, there is no relative disadvantage to any particular carrier. To eliminate misinterpretation, a caveat is placed wherever SMS Crash Indicator-related values are shown. The caveat states, “The list of crashes represent a motor carrier’s involvement in reportable crashes regardless of the carrier’s or driver’s role in the crash.” When a Crash Indicator percentile is relatively high, it suggests that a further examination of causes is needed, and if correctable, action should be taken by the motor carrier. SMS calculations are applied uniformly to all carriers and are adjusted for exposure. For a more detailed explanation of the calculation of the Crash Indicator and its components, please refer to the SMS Methodology document.
However, as of August 1, 2017, FMCSA is conducting a 24-month Crash Preventability Demonstration Program to review the preventability of certain crash types. Throughout the Demonstration Program, FMCSA will maintain data so that at the program’s conclusion, the Agency can conduct analyses to include: the cost of operating the test and its extrapolation to a larger program; future crash rates of carriers that submitted RDRs; future crash rates of motor carriers with Not Preventable crashes; and impacts to the SMS Crash Indicator BASIC and prioritization. The analysis will be used to examine industry assertions that crashes of these types are not preventable and that removing these crashes from motor carriers’ records would result in a better correlation to future crash risk, as well as to inform future policy decisions on this issue.
