The Federal Motor Carrier Safety Administration (FMCSA) is the U.S. government agency that regulates commercial motor vehicles (CMVs) to improve safety and reduce crashes involving trucks and buses. FMCSA sets and enforces rules for driver qualifications, hours of service, vehicle maintenance, drug & alcohol testing, and carrier safety programs.

An FMCSA audit (also called a compliance review) is a formal examination of a carrier’s safety management practices, documentation, and adherence to federal regulations. Audits may occur due to high CSA scores, crashes, complaints, new‑entrant status, or random selection.

During an audit, FMCSA may review:

• Driver qualification files
• Drug & alcohol program records
• Hours of service logs & ELD data
• Vehicle inspection and maintenance records
• Accident register
• Required safety policies

Audit outcomes can include:

• No action
• Required corrective action
• Fines and penalties
• Safety rating downgrade
