DOT Audit Checklist for Small Trucking Companies

Short answer: A DOT compliance review (audit) covers six areas: general compliance, driver qualifications, operational compliance, vehicle maintenance, hazardous materials (if applicable), and accident history. The driver qualification section is where most small carriers fail.

What Is a DOT Audit?

A DOT audit — officially called a Compliance Review — is an on-site examination of your motor carrier operations by an FMCSA investigator. They show up at your place of business (sometimes with advance notice, sometimes not) and go through your records.

The purpose is to determine whether you're meeting federal safety regulations. At the end, you receive a safety rating: Satisfactory, Conditional, or Unsatisfactory.

Who Gets Audited?

• New carriers: FMCSA aims to audit all new carriers within their first 18 months of operation
• Carriers with complaints: A complaint from a driver, shipper, or the public can trigger an audit
• Post-crash: A serious accident involving your driver may trigger an investigation
• Poor roadside inspection scores: High out-of-service rates flag your carrier for review
• Random selection: Yes, it can be random

The Complete DOT Audit Checklist

1. General Compliance

The auditor verifies your basic operating authority and records:

• Valid USDOT number and MC number (if applicable)
• Active operating authority (not revoked or suspended)
• Proper insurance filings (BMC-91 or BMC-34)
• BOC-3 process agent filing
• Unified Carrier Registration (UCR) current
• IFTA credentials (if operating in multiple states)
• Drug and alcohol testing program enrollment with a consortium/TPA

2. Driver Qualification Files (This Is Where Small Carriers Fail)

The auditor pulls files for your drivers and checks each one for:

• Completed employment application (§391.21)
• Copy of valid CDL with correct class and endorsements
• Valid Medical Examiner's Certificate (medical card) — not expired
• MVR inquiry from the past 12 months (§391.23)
• Annual review of driving record — signed and dated (§391.25)
• Road test certificate or CDL equivalent (§391.31/33)
• Previous employer safety performance history — inquiries sent within 30 days of hire (§391.23(d))
• Pre-employment drug test — verified negative result
• Entry-Level Driver Training certificate (for CDLs issued after Feb 2022)

Each missing or expired document = a separate violation = up to $16,000 fine.

3. Hours of Service (HOS)

• ELD records or paper logs for the past 6 months
• Supporting documents (fuel receipts, BOLs, toll receipts)
• Proper use of ELD — no tampering or falsification
• Compliance with 11-hour driving limit, 14-hour window, 30-minute break rule
• 70-hour/8-day or 60-hour/7-day limits

4. Vehicle Maintenance

• Annual vehicle inspection reports (§396.17) — current for all vehicles
• Driver Vehicle Inspection Reports (DVIRs) — pre-trip and post-trip
• Maintenance records showing systematic inspection, repair, and maintenance program
• Brake adjustment records
• Tire condition documentation

5. Hazardous Materials (If Applicable)

• Valid HAZMAT endorsement on driver's CDL
• TSA security threat assessment (renewed every 5 years)
• Proper shipping papers and placarding
• HAZMAT training records
• Emergency response information

6. Accident Register

• Record of all DOT-reportable accidents for the past 3 years
• Each record must include date, location, driver name, injuries, fatalities, and hazmat spills
• Copies of any accident reports filed

Top 5 Reasons Small Carriers Fail Audits

1. Expired medical cards — The single most common violation. The driver's card expired, nobody noticed, and they kept driving.
2. Missing annual MVR reviews — Carriers pull the MVR but skip the written review and sign-off. These are two separate requirements.
3. Incomplete previous employer checks — The 30-day deadline to send inquiries passes and nobody follows up.
4. No pre-employment drug test on file — The driver started working before the test result came back.
5. Sloppy or missing maintenance records — No documentation of a systematic maintenance program.

How to Prepare for a DOT Audit

The best time to prepare for an audit is today — not when you get the notification letter.

1. Audit your own files quarterly. Pull each driver's DQF and check it against the list above. Fix gaps immediately.
2. Set up expiration tracking. Know when every medical card, CDL, and MVR is due. Don't rely on your memory or a spreadsheet you check "when you get around to it."
3. Keep your files organized. Physical or digital — doesn't matter. What matters is that you can produce any document within minutes when the auditor asks for it.
4. Train your drivers. Make sure drivers know they must notify you when documents are renewed and provide copies.
5. Document everything. If a previous employer doesn't respond to your inquiry, document your good-faith effort. If a driver is sent for a drug test, document when.
