What the Regulation Actually Requires

Driver Qualification File requirements are governed by 49 CFR Part 391. Every motor carrier must maintain a DQF for every driver it employs — including owner-operators leased to the carrier, part-time drivers, and drivers who were employed for any portion of the compliance review period.

§ 391.51 is the checklist section of Part 391. It specifies every document that must be in a driver's qualification file and provides the regulatory basis for each requirement. Auditors use § 391.51 as their primary reference when reviewing DQFs.

The 9 Required DQF Documents

1. Application for Employment

Required under § 391.21. Every driver must complete an application for employment that includes a 10-year employment history, covering all employers during that period — not just trucking employers. The application must be signed and dated by the driver.

Auditor note: The employment history must be complete. Gaps in the 10-year history must be explained and accounted for. An application that lists only trucking employers while omitting other employment is incomplete.

2. MVR at Time of Hire

Required under § 391.23(a)(1). You must obtain a motor vehicle record (MVR) from every state where the driver held a license in the previous 3 years. This must be done before the driver makes the first trip for your operation — not after.

Most common finding: The MVR was obtained after the driver's first trip. Even one trip without a compliant hire-MVR on file is a violation.

3. Annual MVR Review

Required under § 391.25. Every year, you must obtain a new MVR for every driver and document that you reviewed it. The review must occur within a 12-month period from the previous MVR. The reviewer's signature and date must be on file.

4. Road Test Certificate

Required under § 391.31 and § 391.33. Every driver must either complete a road test administered by your organization and receive a road test certificate, or present a valid CDL as evidence of equivalent skills — in which case you must document that you accepted the CDL in lieu of the road test.

5. Medical Examiner's Certificate

Required under § 391.43 and § 391.45. Every CDL driver must have a current medical examiner's certificate (the "DOT medical card") on file. The examiner must be listed on the FMCSA National Registry of Certified Medical Examiners.

Expiration matters: A medical card that expires during employment is not automatically renewed. The driver must be re-examined before the expiration date. An expired medical card in your DQF is an immediate violation — and an expired card in the driver's possession during a roadside inspection is a driver OOS condition.

6. Annual Violations Certification

Required under § 391.27. Every year, each driver must provide a written list of all traffic violations (other than parking violations) for which they were convicted or forfeited bond or collateral during the preceding 12 months — for any motor vehicle, not just CMVs. If there were no violations, the driver must certify that fact in writing.

7. Pre-Employment Drug Test

Required under § 382.301. A negative pre-employment drug test result must be on file before a driver operates a CMV for your operation. The result on file must be the Medical Review Officer (MRO) report — not just a collection receipt or preliminary result.

8. Previous Employer Inquiry

Required under § 391.23. Within 30 days of hire, you must contact every DOT-regulated employer the driver worked for in the previous 3 years and request safety performance history — including accident records and drug/alcohol violations. You must document the inquiry and retain all responses.

Clearinghouse intersection: Since 2020, the previous employer inquiry for drug and alcohol violations is handled through the FMCSA Clearinghouse for any employer that was Clearinghouse-registered. You must still contact pre-2020 employers directly for violations prior to Clearinghouse launch.

9. FMCSA Clearinghouse Query

Required under § 382.701. Since January 6, 2020, every carrier must query the FMCSA Drug & Alcohol Clearinghouse before allowing a driver to operate a CMV. A full query (which requires driver consent) must be conducted at pre-employment. A limited query (which does not require driver consent) must be conducted annually for every CDL driver you employ.

If a limited query returns a result indicating that a record exists in the Clearinghouse, you must obtain driver consent and conduct a full query before the driver can continue operating.

Owner-Operators: You Need a DQF on Yourself

This surprises many owner-operators, but it is a firm requirement: if you are an owner-operator with your own DOT authority, you must maintain a Driver Qualification File on yourself. The circular nature of this requirement — you are both the carrier and the driver — does not exempt you from it.

Your own DQF must include:

• Application for employment (completed and signed — by you)
• MVR at time of starting operations
• Annual MVR reviews every 12 months
• Current medical examiner's certificate
• Annual violations certification (signed by you)
• Road test certificate or CDL equivalency notation
• Pre-employment drug test result
• Previous employer inquiry for the previous 3 years of DOT-regulated employment
• FMCSA Clearinghouse pre-employment query result

The Annual Review Process

Under § 391.25, the annual review is a formal process — not just obtaining an MVR. The four required steps:

1. Obtain a current MVR from every state where the driver held a license during the preceding 12 months.
2. Obtain the driver's annual violations certification — the signed list of all traffic violations from the preceding 12 months.
3. Review both documents and determine whether the driver continues to meet the qualification standards of § 391.11.
4. Document the review — sign and date the MVR to certify that you reviewed it and that the driver continues to qualify.

Common failure: Many carriers obtain the MVR but skip the documented review step. The MVR alone is not sufficient — the regulation requires evidence that a responsible person at the carrier reviewed the MVR and determined the driver continues to qualify.
