Driver Qualification File (DQF) Requirements: What 391.51 Demands, the Annual Review, and an Audit-Ready Checklist

A driver qualification file is the folder (paper or electronic) that proves each driver you dispatch was legally qualified on the day they drove. Under 49 CFR 391.51, every motor carrier must keep one for every driver it uses, and the file has to hold specific documents, not just a copy of the CDL. In a new entrant safety audit or a compliance review, the investigator usually pulls a sample of driver files first, and a missing medical certificate or a skipped annual review shows up as a violation for every driver it affects.

Who needs a driver qualification file

Part 391 applies to drivers of commercial motor vehicles in interstate commerce. Under the definition in 49 CFR 390.5, that means a vehicle or combination with a GVWR or GCWR of 10,001 pounds or more, a vehicle designed to carry 9 to 15 passengers for compensation or 16 or more passengers, or any vehicle hauling placarded hazardous materials. The 10,001-pound line catches many operators off guard: a one-ton pickup pulling a gooseneck trailer is often over it, and so is a box truck that never needed a CDL. Part 391 applies whether the driver holds a CDL or not.

A solo owner-operator running under their own authority is both the carrier and the driver, so they need a DQF on themselves. When an owner-operator is leased onto another carrier, the carrier holding the lease keeps the file. Many states have adopted Part 391 for intrastate carriers, sometimes with grandfather or age exceptions, so check your state rules even if you never cross a state line.

What 391.51 requires in every file

The regulation lists the contents. Here is each item with the rule that creates it:

The old annual list of violations from the driver (391.27) was dropped from the rules in 2015. Some carriers still collect it, which is fine, but an auditor won't cite you for not having one.

Two related records are often kept next to the DQF but are separate requirements. Responses to the safety performance history inquiry you send previous DOT-regulated employers (391.23(c) and (d), within 30 days of hire, covering the past 3 years) belong in a Driver Investigation History File with restricted access under 391.53. Drug and Alcohol Clearinghouse records also belong elsewhere: the full pre-employment query and the annual limited query required by 382.701 for CDL drivers. Investigators check both during an audit, so keep them where you can find them quickly.

Road test and its equivalents

Under 391.31, the person giving the road test signs a certificate (391.31(e) lists the required content), and you keep a copy in the file. Section 391.33 lets you skip the road test if the driver presents a valid CDL for the type of vehicle you'll assign, or a road-test certificate issued within the previous 3 years. If you go that route, put a copy of the CDL or the prior certificate in the file. An empty slot where the road test should be is cited even when the driver has years of experience.

The medical card after the 2025 changes

Medical certificates run for 24 months at most, and many examiners issue 1-year or shorter cards for drivers with blood pressure or diabetes issues. The expiration date printed on the card is the one that counts. Since June 23, 2025, certified medical examiners send exam results electronically to FMCSA, which passes them to the state licensing agency for CDL and CLP holders. For those drivers, the MVR showing current medical status is your proof, and 391.51(b)(7)(ii) gives you 15 days after the exam to get it into the file. For non-CDL drivers of 10,001+ pound vehicles, you still need a copy of the paper certificate. Either way, print the National Registry lookup showing the examiner was listed on the exam date.

The 12-month annual review

Section 391.25 combines two tasks on one 12-month cycle. First, request an MVR from every state that licensed the driver during the year. Second, review it against the disqualification standards in 391.15 and the safe-driving standard, and sign a note with the reviewer's name and the date. An MVR sitting in the file with no signed review is a 391.25 violation. "12 months" means 12 months from the previous review, not calendar year-end, so a driver hired in March who was last reviewed the following April is already overdue.

For a small fleet, the simplest fix is to anchor every driver's MVR pull to their hire-date anniversary and pull it 30 days early. That way a slow state response doesn't push you past the deadline.

Retention after a driver leaves

Section 391.51(c) requires you to keep the whole file for as long as the driver works for you, plus 3 years after they leave. Section 391.51(d) lets you remove some items 3 years after they were created, even while the driver is still employed: annual MVRs, annual review notes, medical certificates with their Registry verifications, and medical variances. The application, the pre-employment MVR, and the road test certificate stay for the whole employment period plus 3 years. Electronic files are fine under 390.32, as long as you can produce legible copies when the investigator asks.

DQF deficiencies FMCSA cites most often

• No DQF at all (391.51(a)): common for owner-operators who never made one for themselves. This is a critical violation.
• Expired or missing medical certificate (391.45(a), 391.51(b)(7)): the driver ran loads after the card expired. Also critical, and cited per driver.
• No pre-employment MVR inquiry (391.23(a)), or one that covers only the current state when the driver held licenses in two others.
• Annual MVR with no signed review note (391.25), or a review that is 13 or more months old.
• No National Registry verification for the medical examiner.
• Application missing the 10-year CMV history for CDL drivers, or unsigned.
• No road test certificate or copy of the license accepted in lieu.
• Using a disqualified driver (391.15(a)) because nobody read the MVR. This is an acute violation and the most expensive one on this list.

Audit-ready DQF checklist

1. List every person who drove a 10,001+ lb CMV for you in the last 3 years, including yourself and part-timers.
2. Confirm each has a signed 391.21 application with 3-year employer and 10-year CMV history.
3. Confirm a pre-employment MVR from each state licensed in the prior 3 years, dated within 30 days of hire.
4. Confirm a road test certificate or a copy of the CDL or prior certificate accepted under 391.33.
5. Confirm a current medical certificate (or CDLIS MVR showing it), the National Registry printout, and any variance.
6. Confirm an annual MVR and a signed, dated review within the last 12 months.
7. Confirm safety performance history inquiries and Clearinghouse queries are on file, stored separately.
8. Set calendar alerts for each driver's medical expiration and MVR anniversary, 30 days ahead.
9. Move files of former drivers to a terminated folder and mark the purge date: separation date plus 3 years.

Frequently asked questions

Do I need a DQF for a driver who only drives occasionally?

Yes. Section 391.63 relaxes a few steps for intermittent, casual, or trip-lease drivers, but the driver still has to be qualified, and you must keep proof of that, including the medical certificate.

Can I keep driver qualification files electronically?

Yes. Section 390.32 allows electronic records and signatures, as long as the documents are accurate and you can produce them when an investigator asks.

How long do I keep the annual MVRs?

Three years from the date each one was made. After that you can remove it, even if the driver still works for you.
