DOT Audit Checklist: The Files Auditors Ask For First

Key takeaways

• Auditors ask for five folders: driver files, hours of service, vehicle files, drug & alcohol records, and company records.
• Every record type has its own retention period. The table below lists each one with its regulation.
• The failures are almost never mechanical. They are missing paper.

The checklist

Auditors typically start with these folders. If every one is complete and current, you're most of the way to passing. Expect the auditor to ask first for your current driver list and vehicle list, then sample files from both.

Driver files

• Driver qualification file for every driver, built before their first dispatch: application, first MVR, road test certificate (or the CDL copy accepted in its place), medical certificate (for CDL drivers, the MVR showing current medical status)
• Every year after hiring: a fresh MVR, your written annual review of their driving record, and the driver's certificate of violations
• For drivers without a CDL, a note confirming the medical examiner was on the National Registry. For CDL drivers, that proof rides on the driving record itself
• Previous employer safety history, in a separate investigation file with controlled access: the driver's written authorization, your inquiries to each employer from the last 3 years, their answers or your documented good faith attempts. Drug and alcohol history for FMCSA-regulated employers comes through the Clearinghouse

Hours of service

• ELD records and logs for every trip
• Supporting documents that match the logs: bills of lading, dispatch records, fuel and toll receipts, payroll records

Vehicle files

• A maintenance file per vehicle: what was inspected and repaired, and when
• Annual inspection reports, one per vehicle per year
• Driver vehicle inspection reports (DVIRs) with every defect certified repaired (or certified as not needing repair) before the truck rolled again
• Roadside inspection reports: every violation certified corrected within 15 days of the inspection, and the reports kept 12 months

Drug & alcohol program

• Proof of consortium enrollment, or your in-house program documents
• Your written drug & alcohol policy, the one every driver receives, with its education materials
• Pre-employment drug test results, received before the driver first drives
• Random pool records and selection records
• Supervisor training certificates: anyone who can order a reasonable suspicion test needs 60 minutes of training on alcohol and 60 minutes on controlled substances
• Clearinghouse query records: pre-employment and annual

Company records

• Proof of insurance at the required minimums
• Accident register, current, with the details for every accident
• Current MCS-150 and registration information
• UCR registration proof for the current year
• Lease agreements for every leased truck, trailer, or driver

How long to keep each record

Throwing records away too early is its own violation. These are the federal minimums:

One nuance inside the DQ rule: the annual MVRs, annual review notes, and medical certificates inside a file can come out 3 years after their own date, even while the rest of the file stays.

How to organize it

You don't need fancy software. You need a system you'll actually maintain:

• One folder per driver, one per vehicle. Physical binder or digital, doesn't matter.
• File things the day they happen. The gap between "I'll file it Friday" and an audit is where carriers die.
• Name files consistently: MVR-2026-drivername.pdf beats scan0032.pdf when an auditor is watching you search.
• Keep a master checklist (like the one above) taped inside the cabinet or pinned in your drive. Check off each document as it's filed.

Keep it current

• File the DVIR daily: defects noted today, repaired tomorrow, receipt filed the same week.
• Review one driver file per month on rotation. You'll catch expirations before an auditor does.
• After any hire, crash, or new truck, update the affected folders within days, not "when things slow down."

The gaps that fail people

The same three gaps show up in failed audits again and again:

1. Driver files started late: the DQ file must exist before the driver drives, not after the audit notice arrives.
2. Maintenance with no paper trail: the work was done, but nobody kept the receipt. If it isn't documented, it didn't happen.
3. No drug & alcohol program at all: for new entrants, that alone fails the safety audit automatically.

Make it a habit, not a scramble

The carriers who pass easily do a quarterly self-audit: pull one driver file, one vehicle file, and one month of logs, and review them like an auditor. Thirty minutes, four times a year, beats a panic week every time.
