Driver Qualification File (DQ File)

A driver qualification file (DQ file) is the set of records a motor carrier must keep for each commercial motor vehicle (CMV) driver it employs to prove the driver is qualified under FMCSA rules in 49 CFR Part 391. It includes the employment application, motor vehicle records, road test documentation, medical certification and the annual driving record review.

DQ files are one of the first things auditors check during a DOT compliance investigation or new entrant safety audit. A complete, current file shows that the carrier verified each driver's history, license and fitness before putting them behind the wheel, and kept checking afterward.

What Is a Driver Qualification File?

Under 49 CFR 391.51, each motor carrier must maintain a driver qualification file for each driver it employs. The file may be combined with the driver's personnel file. The requirement applies to drivers of CMVs in interstate commerce, which under 49 CFR 390.5 generally includes vehicles that:

• Have a gross vehicle weight rating or gross combination weight rating (or actual weight) of 10,001 pounds or more
• Are designed or used to transport more than 8 passengers, including the driver, for compensation
• Are designed or used to transport more than 15 passengers, including the driver, not for compensation
• Transport hazardous materials in a quantity that requires placards

This means DQ files are required for many drivers who do not hold a commercial driver's license (CDL), such as drivers of box trucks or pickups towing trailers above 10,001 pounds. Many states apply similar rules to intrastate carriers, sometimes with different thresholds.

What Documents Go in a DQ File?

Section 391.51(b) lists the required contents:

1. Employment application (391.21). The signed application covers the driver's employers for the previous 3 years. Drivers who need a CDL must also list employers they drove a CMV for during the 7 years before that.
2. Pre-employment motor vehicle record (391.23(a)(1)). An MVR from each licensing authority where the driver held a license or permit during the previous 3 years, obtained within 30 days of the date employment begins.
3. Road test certificate or equivalent (391.31 or 391.33). Either the carrier's road test certificate or a copy of an accepted equivalent, such as a valid CDL, which carriers may accept in place of a road test.
4. Annual MVR (391.25(a)). An MVR from each licensing authority where the driver holds or held a CMV license or permit, obtained at least once every 12 months.
5. Annual review note (391.25(c)(2)). A note showing the carrier reviewed the driver's record to decide whether the driver meets minimum requirements for safe driving, including the name of the person who performed the review.
6. Medical certification. The medical examiner's certificate under 391.43, or for CDL holders, an MVR from the current licensing state showing medical certification status. Medical certificates are valid for up to 24 months.
7. Medical variance documents, if applicable. A Skill Performance Evaluation Certificate under 391.49 or a medical exemption letter, when the driver qualified through one of these programs.
8. National Registry verification. A note confirming the medical examiner was listed on the National Registry of Certified Medical Examiners.

Related records kept separately

Some driver records are required but belong in other files:

• Driver investigation history file (391.53): safety performance history from DOT-regulated employers the driver worked for in the previous 3 years, requested under 391.23(d). This file has specific confidentiality and access rules.
• Drug and alcohol records (Part 382): for CDL drivers, pre-employment drug test results and Drug and Alcohol Clearinghouse queries. Part 382 requires these records to be kept in a secure location with controlled access, so most carriers store them apart from the DQ file.

DQ File Retention Requirements

Section 391.51(c) requires the carrier to keep the DQ file for as long as the driver is employed and for 3 years after employment ends.

Under 391.51(d), certain documents may be removed 3 years after the date they were executed:

• Annual MVRs and annual review notes
• Medical examiner's certificates, or for CDL drivers, the MVRs used as proof of medical certification
• Skill Performance Evaluation Certificates and medical exemption letters
• National Registry verification notes

The application, pre-employment MVR and road test documentation stay in the file for the full period of employment plus 3 years.

Recent Changes to DQ File Rules

Annual list of violations removed

A 2022 FMCSA final rule, effective May 9, 2022, rescinded 49 CFR 391.27, which had required drivers to give their carrier an annual list of traffic violations. The same rule changed the annual MVR requirement in 391.25 so carriers must obtain records from each licensing authority where the driver holds or held a CMV license, including authorities in Canada and Mexico.

Electronic medical certification for CDL drivers

Under the National Registry II rule, states were required to begin receiving medical examination results electronically from FMCSA's National Registry by June 23, 2025, and to post them to the driver's CDL record. For CDL holders, the MVR showing medical certification status becomes the main proof of medical qualification. In states that had not yet implemented the change, FMCSA guidance says drivers continue to receive paper certificates, and carriers may use a copy as proof for up to 15 days from the issue date. Drivers who do not need a CDL still use the paper medical examiner's certificate.

How to Build a DQ File for a New Driver

1. Collect a complete application. Check that employment history covers the required years, with no unexplained gaps, and that the driver signed and dated it.
2. Request the safety performance history. Contact DOT-regulated employers from the previous 3 years and place their responses in the driver investigation history file.
3. Run the required queries. For CDL drivers, complete a full Clearinghouse query and receive a negative pre-employment drug test before any safety-sensitive work.
4. Order MVRs. Obtain an MVR from every licensing authority the driver held a license in during the past 3 years, within 30 days of hire.
5. Verify the road test. Conduct a road test and issue a certificate, or document an accepted equivalent.
6. Confirm medical qualification. Verify the medical certificate or CDL record status, and confirm the examiner is listed on the National Registry.
7. Set recurring reminders. Track expiration and renewal dates for the medical certificate, license, annual MVR and annual review.

Common DQ File Mistakes to Avoid

• Letting a driver operate with an expired medical certificate.
• Pulling an annual MVR but not documenting the annual review.
• Requesting an MVR from only the current state when the driver held licenses in other states.
• Skipping the National Registry verification note.
• Assuming non-CDL drivers of vehicles over 10,001 pounds are exempt.
• Purging files too early after a driver leaves, or keeping drug test results in an openly accessible personnel file.

Why DQ Files Matter

A DQ file is the carrier's evidence that it screened and monitored each driver as the regulations require. Missing or outdated documents can lead to violations during an audit and can affect the carrier's safety rating. After a crash, the file is often requested in litigation to show whether the carrier exercised reasonable care in hiring and retaining the driver. Good DQ file management also connects to daily fleet safety practices, such as reviewing driver vehicle inspection reports and maintaining a vehicle accident register. Regular internal audits of a sample of files help catch gaps before regulators do, and fit within a broader safety management system.

How SMS360 Helps

The SMS360 Driver Qualification module helps fleets keep DQ file records organized in one place. Teams can store each driver's documents, track expiration dates for medical certificates, licenses and annual reviews, and receive reminders before items lapse. Dashboards show which files are complete and which need attention, and mobile access makes it easier to collect documents from drivers in the field. Having records available on demand also simplifies preparation for DOT audits.

Frequently Asked Questions

What documents are required in a driver qualification file?

A DQ file must include the driver's employment application, the pre-employment MVR, a road test certificate or accepted equivalent, annual MVRs, notes of the annual driving record review, medical certification, any medical variance or Skill Performance Evaluation Certificate, and a note verifying the medical examiner is on the National Registry. These requirements are listed in 49 CFR 391.51(b).

How long do you have to keep a DQ file?

A motor carrier must keep the DQ file for the entire time the driver is employed and for 3 years after employment ends. Some documents, including annual MVRs, annual review notes, medical certificates and National Registry verification notes, may be removed 3 years after the date they were executed, even while the driver is still employed.

Do non-CDL drivers need a driver qualification file?

Yes, if they operate a commercial motor vehicle in interstate commerce. The FMCSA definition includes vehicles with a weight rating of 10,001 pounds or more, which is well below the 26,001-pound CDL threshold. Drivers of many box trucks, service trucks and pickup and trailer combinations therefore need a DQ file and a medical certificate even without a CDL.

How often must a driver's MVR be reviewed?

At least once every 12 months. Under 49 CFR 391.25, the carrier must obtain an MVR from each licensing authority where the driver holds or held a CMV license or permit, review it to determine whether the driver meets minimum requirements for safe driving, and place a note of the review, including the reviewer's name, in the DQ file.
