What is included in the Behavior Analysis and Safety Improvement Categories' (BASICs)
details of the Safety Measurement System (SMS)?
Each BASIC's details page, except where noted, consists of five parts:
- BASIC Overall Status: A 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).
- Data Center: Provides a means to download the roadside and investigation
data that SMS uses. Users can download data in Excel (XLS) or XML format for the
selected BASIC or for all BASICs.
- On-road Performance Detail tab: Provides the SMS measure, assigned percentile,
and supporting information for the selected BASIC. This includes a summary listing
of violations and their violation weights, and a listing of the relevant inspections
for the BASIC. The full inspection report can also be accessed from this section.

a Serious Violation was discovered, the violation and the date it was cited are
- Performance Tools tab: Presents a series of graphs that can assist a motor
carrier in determining its performance under the selected BASIC. Two graphs are
provided: one lists the relevant inspections versus the inspections with a violation
in the selected BASIC by month for the 24-month period of the SMS results, and the
second graph presents the SMS results for the entire safety event group in the selected
BASIC. The graph presents the measure on the vertical axis and the percentile on
the horizontal axis for the safety event group.
