DOT audits can feel intimidating, but most audit problems don’t come from unsafe operations. They come from missing, disorganized, or incomplete documentation.
Whether you’re facing a DOT safety audit, a compliance review, or preparing as a new entrant, the key to passing is simple: “Have the right documents, organized and ready to show.”
This guide explains DOT audit prep basics, what FMCSA actually looks for, and how to organize your records so you’re audit-ready.
What Is a DOT Audit or Compliance Review?
A DOT audit (also called a compliance review or safety audit) is FMCSA’s way of verifying that your company:
- Understands federal safety regulations
- Follows required procedures
- Can prove compliance with documentation
Audits may be:
- On-site or off-site
- Triggered by new authority status, inspections, crashes, or complaints
FMCSA does not rely on verbal explanations. Proof wins.
Core DOT Audit Document Sets
These are the primary FMCSA safety audit documents carriers are asked to provide.
1. Driver Qualification Files (DQFs)
Required under 49 CFR §391.51
Each DQF should include:
- Driver application
- Motor Vehicle Records (MVRs)
- Medical Examiner’s Certificate
- Prior employer drug & alcohol checks
- Road test or CDL copy
- Annual reviews (if applicable)
Missing or incomplete DQFs are one of the top DOT audit violations.
2. Drug & Alcohol Compliance (49 CFR Part 382)
FMCSA closely reviews drug and alcohol records.
You should have:
- Written drug & alcohol policy
- FMCSA Clearinghouse registration
- Pre-employment full queries
- Annual limited queries (382.701)
- Random testing selections & results
- Follow-up or return-to-duty records (if applicable)
Failure in this area can result in automatic audit failure.
3. Hours-of-Service (HOS) Records
Auditors expect:
- ELD data (or paper logs if exempt)
- Log edits and audit trail
- Supporting documents (fuel, tolls, BOLs)
- Evidence of log monitoring and corrections
DOT looks for patterns, not just one clean week.
4. Vehicle Files & Maintenance Records
Each power unit should have:
- DVIRs
- Preventive maintenance records
- Repair documentation
- Annual inspection reports
FMCSA verifies that defects were corrected and documented, not just noted.
5. Insurance & Accident Register
Keep available:
- Current insurance certificates
- DOT accident register
- Accident documentation and corrective actions
Auditors often review this early in the audit.

Using these resources during preparation shows good-faith compliance.
How to Get Ready for a DOT Audit (Step-by-Step)
1. Organize Documents by Category
Use your compliance portal to group files into:
- Drivers
- Drug & alcohol
- HOS
- Vehicles
- Insurance & filings
Avoid mixing everything into one folder.
2. Run an Internal Mock Audit
Review your records using FMCSA checklists:
- Pretend you’re the auditor
- Sample drivers and vehicles
- Check for missing or expired documents
Mock audits catch issues before FMCSA does.
3. Fix Gaps & Record Corrective Actions
If you find problems:
- Correct them immediately
- Document what was fixed and when
FMCSA expects to see corrective action, not perfection.
4. Keep Filing Confirmations Handy
Always store confirmation PDFs for:
- MCS-150 updates
- UCR filings
- BOC-3 submissions
- Insurance filings
Missing proof can still result in violations.
Special Note for New Entrants
If you’re a new authority, you are enrolled in FMCSA’s New Entrant Safety Assurance Program.
You must:
- Operate compliantly during the monitoring period
- Pass a New Entrant Safety Audit
- Demonstrate basic safety management controls

Frequently Asked Questions (FAQs)
FMCSA typically reviews Driver Qualification Files, drug and alcohol compliance records, Hours-of-Service logs, vehicle maintenance files, insurance documents, and an accident register. Documentation must be complete and current.
Retention periods vary by document type, but many DOT records must be kept for at least 6 months to 3 years. FMCSA regulations specify exact retention requirements by category.
The most common reason is missing or incomplete documentation, not unsafe driving. FMCSA requires proof that safety processes exist and are followed.
A DOT compliance portal centralizes documents, tracks expirations, stores proof, and supports mock audits, making it easier to respond quickly and accurately during FMCSA audits.
