DOT Compliance Manual for Fleet Managers
A working overview of the FMCSA compliance areas every motor carrier is responsible for maintaining, and what a DOT auditor typically reviews.
Written for: Fleet managers, safety directors. This guide is general educational information — permit, escort, and compliance requirements vary by state and by load. Contact our team to confirm what applies to your specific move.
Driver qualification files
FMCSA requires a qualification file for every driver, including their application, motor vehicle record, road test or equivalent, medical certificate, and annual review of driving record. Missing or outdated documents in a driver's file are among the most common findings in a DOT audit.
Hours of Service and ELD records
Hours of Service (HOS) rules limit how long a driver can be on duty and driving before a required rest period. Since the ELD mandate, most carriers are required to log this electronically, and auditors will typically review ELD records for HOS violations, unassigned driving time, and malfunction handling.
Drug and alcohol testing program
Carriers are required to maintain a drug and alcohol testing program covering pre-employment, random, reasonable suspicion, and post-accident testing, along with enrollment in the FMCSA Drug and Alcohol Clearinghouse.
Vehicle maintenance records
Carriers must maintain maintenance and inspection records for every vehicle, including driver vehicle inspection reports (DVIRs) and annual inspections, showing that defects are identified and repaired.
What a DOT audit typically covers
A DOT audit generally reviews these same categories — driver files, HOS/ELD records, drug and alcohol program records, and maintenance records — alongside your CSA BASIC scores. Carriers that run a mock audit ahead of time are generally in a better position to catch gaps before an FMCSA auditor does.
