DOT Compliance Checklist for Small Carriers and Safety Managers
Most DOT audit problems aren't caused by bad drivers. They come from missing paperwork. This checklist covers the core FMCSA record-keeping areas a small carrier or new safety manager should have in order: driver qualification files, drug and alcohol testing, hours of service, vehicle maintenance and accident records.
This is a general educational overview of the Federal Motor Carrier Safety Regulations (FMCSRs), not legal advice. Requirements depend on your operation. Always check the current regulations at fmcsa.dot.gov.
1. Driver qualification (DQ) files: 49 CFR Part 391
Keep a DQ file for each CDL or commercial driver you employ. It typically includes:
- a completed employment application
- a motor vehicle record (MVR) from each state where the driver held a license in the past 3 years, obtained at hire
- a road test certificate, or an accepted equivalent such as a CDL
- a current medical examiner's certificate, and verification that the medical examiner is on the National Registry
- an annual MVR review, documented
- safety performance history inquiries to previous DOT-regulated employers from the past 3 years
Common audit finding: expired medical certificates and missing annual reviews. Use a calendar or software to track expiration dates.
2. Drug and alcohol testing: 49 CFR Parts 40 and 382
- written drug and alcohol policy given to every driver
- enrollment in a random testing program (often through a consortium for small carriers)
- a negative pre-employment drug test before the driver performs safety-sensitive functions
- FMCSA Drug & Alcohol Clearinghouse: a full pre-employment query and at least an annual query for every driver
- supervisor training for reasonable-suspicion testing
- post-accident, return-to-duty and follow-up testing when required
Owner-operators with their own authority must still be in a random testing program and use the Clearinghouse.
3. Hours of service: 49 CFR Part 395
- registered ELDs in use, unless an exemption applies
- records of duty status and supporting documents (fuel receipts, bills of lading, dispatch records) kept for 6 months
- a process to review logs for violations and correct drivers
- dispatchers who never pressure drivers to exceed their hours
Dispatch and safety work together here. Planning loads around the driver's available hours is part of compliance.
4. Vehicle inspection, repair and maintenance: 49 CFR Part 396
- a systematic maintenance file for each power unit and trailer you control for 30 days or more
- annual periodic inspection reports for each vehicle
- driver vehicle inspection reports (DVIRs) when defects are reported, with repairs documented
- roadside inspection reports reviewed and acted on
5. Insurance, registration and accident records
- insurance filings current with FMCSA at the required minimum levels
- USDOT registration updated with the MCS-150 biennial update
- an accident register covering the past 3 years (49 CFR 390.15)
- UCR registration paid each year where required
- IFTA and IRP current if you operate qualified vehicles across jurisdictions (see our IFTA filing guide)
6. Monitor your safety data
Check your carrier's SMS (CSA) data regularly. Roadside violations feed your BASIC scores, and a pattern of violations can trigger an investigation. Challenge incorrect inspections through DataQs.

Frequently asked questions
What is in a driver qualification file?
Typically the employment application, MVRs, a road test certificate or equivalent, the medical examiner's certificate with National Registry verification, annual MVR reviews and previous-employer safety performance history inquiries.
How long must I keep hours-of-service records?
Records of duty status and supporting documents are generally kept for 6 months.
Do owner-operators need drug testing?
Yes. An owner-operator with their own authority must be in a random drug and alcohol testing program, often through a consortium, and must use the FMCSA Clearinghouse.
What triggers a DOT audit?
New entrant safety audits happen for new carriers. Investigations can also be triggered by high CSA scores, crashes or complaints.
