The driver qualification file is the most common reason a small carrier fails a new-entrant audit. Not because the rules are mysterious — they're spelled out in 49 CFR §391.51 — but because a single missing item makes the whole file out of compliance. This guide walks every item.
What a DQF is, and what it isn't
A driver qualification file is the FMCSA-mandated dossier of documents that prove a driver is legally and physically qualified to operate a commercial motor vehicle. It is not an HR file. It is not a personnel folder. It does not include payroll, performance reviews, or disciplinary write-ups. The DQF is its own thing, governed by 49 CFR §391, and it has a specific composition and specific retention rules.
Every driver — including the owner-operator who is also the only driver — needs a DQF. The §391 requirements have very narrow exemptions and "I'm the owner" is not one of them.
The 13 items required by §391.51(b)
1. Driver's application for employment
Required by §391.21. Must contain the items listed in §391.21(b): name, address, social security number, employment history for the past three years, list of any commercial motor vehicle accidents in the past three years, all CDLs held in the past three years, and so on.
For a single-driver owner-operator, you complete this form on yourself. Yes, even if you're the company. The form date should be the date you began operating under your USDOT number.
Retention: Duration of employment + 3 years.
2. Inquiry to previous employers
Required by §391.23(a)(2). For each commercial motor vehicle employer in the past three years, you (or someone on your behalf) must contact them and request specific information: dates of employment, accidents, and any drug & alcohol testing program participation.
The Drug & Alcohol Clearinghouse covers a piece of this — but the previous-employer inquiry is broader than just D&A and you still need to document each contact attempt.
Retention: Duration of employment + 3 years.
3. Inquiry to state agencies (MVR check)
Required by §391.23(a)(1). You must obtain a motor vehicle record (MVR) from every state where the driver held a CDL or had a driver's license in the past three years. For most owner-operators that's one or two states.
Retention: Duration of employment + 3 years for the initial inquiry; subsequent annual MVRs follow item 8 below.
4. Annual driving-record inquiry response
Required by §391.25(a). At least once every 12 months you must obtain a new MVR for each driver. Same MVR pull as the initial inquiry, just done annually.
Retention: 3 years per inquiry.
5. Note of annual review of driving record
Required by §391.25(b). After receiving the annual MVR, the carrier must conduct a written review of the record and document that the review took place — including any disqualifying offenses, any pattern of unsafe driving, and the carrier's determination of continued qualification.
This is the item carriers most often skip. The MVR alone is not enough. You also need the review document.
Retention: 3 years per review.
6. List of certified violations
Required by §391.27. At least once every 12 months, the driver must furnish the carrier a list of all moving traffic violations of which they were convicted in the past 12 months — including those occurring outside CMV operation.
Retention: 3 years per list.
7. Road test certificate
Required by §391.31. The driver must pass a road test administered by a qualified person, or the carrier may accept a CDL in lieu of a road test under §391.33(a)(1).
If you accept a CDL in lieu of road test, you need a copy of the CDL on file and a written acceptance under §391.33.
Retention: Duration of employment + 3 years.
8. Medical examiner's certificate
Required by §391.41 through §391.43. The driver must hold a current medical examiner's certificate issued by a certified medical examiner on the FMCSA National Registry. CDL holders' certifications are now uploaded automatically to the state and reflected on the MVR — but you still need a copy of the certificate or National Registry verification on file.
Retention: 3 years from date of examination, OR the certificate must be current — whichever ends later.
9. Skill performance evaluation certificate (if applicable)
Required by §391.49. Only applies to drivers operating under a Skill Performance Evaluation Certificate for a physical impairment.
Retention: Duration of employment + 3 years.
10. Medical variance documentation (if applicable)
Required for drivers operating under a vision or diabetes exemption. Same retention as item 9.
11. Pre-employment drug test result
Required by §382.301. The driver must have a verified negative drug test result on file before performing safety-sensitive functions.
Retention: 5 years for negative results; longer for positive, refusal, or other non-negative outcomes per §382.401.
12. Documentation of previous-employer drug & alcohol testing inquiry
Required by §391.23(d) and §382.413. This is closely related to item 2 but specifically covers drug & alcohol program inquiries — including a Clearinghouse query under §382.701.
Retention: Same as the previous-employer inquiry.
13. Disqualification documentation (if applicable)
Required by §391.27 and §391.51(b)(8). If a driver is disqualified for any reason, the carrier maintains documentation of the disqualification, the basis, and any corrective action.
Retention: Duration of employment + 3 years.
Common DQF mistakes
- Missing the annual review note (item 5). Carriers pull the MVR, file it, and forget the written review. The MVR alone doesn't satisfy §391.25(b).
- Stale MVRs. The annual MVR must be no older than 12 months. A 13-month-old MVR is non-compliant.
- Expired medical certificates. A driver operating with an expired medical certificate is operating illegally. Track every cert's expiration date.
- Missing CDL on file. If you accept the CDL in lieu of road test, you need a current copy of the CDL.
- No previous-employer inquiry documentation. You sent the requests; did you keep proof? Email confirmations, fax receipts, and certified mail receipts all count. "I called them" doesn't.
- Single-driver owner-operator with no DQF on themselves. This is the most common new-entrant failure. The owner-operator IS a driver under §390.5. The DQF rules apply.
What to keep, and where
Each driver gets one folder. Inside the folder, organize the 13 items in the §391.51 numerical order so an auditor can scan it in two minutes. Documents go in as PDFs (or originals if paper); emails go in as printed PDFs with headers visible. Every retention period is tracked.
Roadworthy HQ enforces the §391.51 list automatically: every driver has a DQF view that shows present items, missing items, and items approaching their renewal date. Retention is enforced by the database — documents purge automatically when the CFR retention period ends, with a 7-day grace window and legal-hold support.
If you'd rather build it yourself in a spreadsheet, the structure above is the one auditors recognize.
Try the DQF Completeness Checker
Before your audit letter arrives, run your file through the DQF Completeness Checker. It takes about 10 minutes, walks every §391.51(b) item, and outputs a gap report you can save or print.
