Compliance, Safety, Accountability (CSA)


CSA is FMCSA's data-driven safety compliance and enforcement program designed to improve safety and prevent commercial motor vehicle (CMV) crashes, injuries, and fatalities. CSA consists of three core components; the Safety Measurement System (SMS); interventions; and a Safety Fitness Determination (SFD) rating system to determine the safety fitness of motor carriers.

We Measure

The SMS uses data from roadside inspections and crash reports from the last two years, and data from investigations to identify carriers with safety performance and compliance problems for interventions.

We Intervene

CSA investigators are equipped with a variety of interventions to contact and work with motor carriers that have safety performance and compliance problems.

We Evaluate

The SFD assesses the safety fitness of motor carriers to help FMCSA remove carriers that are unfit to operate from our Nation's roads.
