The SMS uses data from roadside inspections and crash reports from the last two years, and data from investigations to identify and intervene with motor carriers that pose the greatest risk to safety.
FMCSA updates the SMS once a month and organizes the data into seven Behavior Analysis and Safety Improvement Categories (BASICs). The SMS groups carriers by BASIC with other carriers that have a similar number of safety events and then ranks carriers and assigns a percentile to prioritize them for interventions. To learn about SMS’s effectiveness, visit the SMS Effectiveness Test page.
Complete SMS results are available to enforcement users and carriers that are logged into their own safety profiles. For more information on what SMS data is available to the public, review this FAQ.
