Frequently Asked Questions
The Frequently Asked Questions (FAQs) are questions and answers about Compliance,
Safety, Accountability (CSA) that the Federal Motor Carrier Safety Administration
(FMCSA) compiled to assist the public. As questions come in through the website,
FMCSA adds them to the database along with their answers. If you do not see your
question or topic addressed, please
by submitting a feedback form. We will respond to you directly and consider your
question for inclusion in the FAQs.
The FAQ area has recently been enhanced. Users can now search FAQs by stakeholder
group, topics (displayed on the left side of the page), or by entering a keyword
below. Choosing “Show All” will display the entire collection of FAQs.
What is the Driver Safety Measurement System (DSMS) and how is it used?
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
