The Frequently Asked Questions (FAQs) are questions and answers about Compliance,
Safety, Accountability (CSA) that the Federal Motor Carrier Safety Administration

FMCSA adds them to the database along with their answers. If you do not see your

The FAQ area has recently been enhanced. Users can now search FAQs by stakeholder

If my Safety Measurement System Behavior Analysis and Safety Improvement Categories
(BASICs) percentile ranks go up, what will happen?
Answer
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.
