How to Prepare for a DOT Audit — What Carriers Need to Know

DOT audits are easier than carriers think — if your records are in order. Auditors aren't trying to ruin your business. They're checking whether you can prove the operations decisions you've already made. Pass = your paperwork matches your operations. Fail = it doesn't.

What triggers an audit

• New entrant safety audit — every carrier within 12 months of getting authority
• BASIC scores out of compliance — Hours of Service, Vehicle Maintenance, Driver Fitness, etc.
• Crash with injuries or fatalities
• Complaint or whistleblower reports
• Random selection

What the auditor will ask for

DQ files for every active driver, HOS logs for the past 6 months, vehicle maintenance records, drug and alcohol program records, driver disciplinary records, accident register, and proof of insurance. They will also pull samples of drivers and trucks at random and trace every documented event back to the source records.

Quarterly punch list

Run this every quarter — not the week before the audit.

• Every active driver: DQ file complete, current MVR, current medical card, annual review on file
• Every truck: current annual inspection, current registration, IFTA decals current, insurance card in cab
• HOS: every log signed, every edit annotated, every supporting document linked to the trip
• Drug program: random selections happened, results are filed, Clearinghouse queries are current
• Accident register: every preventable + non-preventable incident in the last 12 months
• Insurance: certificate on file, MCS-90 endorsement filed

What to do during the audit

Be cooperative, be specific, don't volunteer extras. If the auditor asks for one driver's MVR, give them that one. They will ask for more if they want more. Provide every document they request through a single point of contact at your company so you don't end up with three different people answering with three different versions of the same document.

If you fail

A conditional rating is a warning shot — fix the findings inside the cure period and re-rate. An unsatisfactory rating, if not fixed, leads to revocation of your authority. Both are recoverable. The worst outcome is letting the rating stand because you didn't act on the findings — that's how good carriers lose their authority.
