The Complete DQ File Checklist Under 49 CFR §391.51

The Driver Qualification (DQ) file is the federal paperwork trail that proves every commercial driver you employ is legally fit to operate the vehicle they have been assigned to. It is required for every CDL driver and most non-CDL commercial drivers, and it is the very first thing an FMCSA auditor asks to see during a compliance review. A missing document — or even a complete document filed in the wrong place — can trigger a violation on the audit report and roll directly into your CSA score.

The contents are not optional and they are not negotiable. Every requirement is spelled out in 49 CFR §391.51, and the regulation lists each document by name. This guide walks through every required item, in the order it typically arrives during the hiring process, with a one-line summary of why FMCSA wants to see it.

The legal foundation

The §391.51 contents requirement reads, in summary form:

49 CFR §391.51(a) — Each motor carrier shall maintain a driver qualification file for each driver it employs. The driver qualification file may be combined with the driver's personnel file.

49 CFR §391.51(b) — The driver qualification file shall include the documents listed in paragraphs (b)(1) through (b)(11) of this section.

49 CFR §391.51(d) — The motor carrier shall maintain the documents listed for as long as the carrier employs the driver and for three years thereafter.

The retention rule is important: even after termination, you keep the entire DQ file for three years. Auditors routinely ask to see files for drivers who left the company eighteen months earlier.

The complete checklist, in filing order

Here is every document required by §391.51, in the order you collect them during the hiring process. For each item we have noted the regulation citation and the practical reason FMCSA wants it on file.

1. Application for Employment

The application is the first piece of paper in the file and the foundation for almost every verification step that follows. Required by §391.21, the application must include:

• The driver's full name, address, date of birth
• Names and addresses of every employer for the previous three years (ten years for CMV employment)
• The reason for leaving each
• Whether the driver was subject to FMCSA regulations or DOT-controlled-substance rules at each
• A list of all motor vehicle accidents in the last three years
• A list of all violations of motor vehicle laws (other than parking) for the last three years
• Any denial, revocation, or suspension of any license, permit, or privilege to operate a motor vehicle
• A signed certification by the driver that everything stated is true

49 CFR §391.21(b) — Required application contents.

The application is not just a hiring form — it is the source-of-truth document the rest of the file is built against. If the driver omits an employer here and you fail to catch it, you have just inherited their disclosure problem.

2. Inquiry to State Agencies (Pre-Employment MVR)

Before placing the driver on the road, you must obtain a Motor Vehicle Record from every state where the driver held a license or permit during the prior three years.

49 CFR §391.23(a)(1) — Inquiry into the driver's driving record during the preceding three years.

The MVRs themselves go in the file, dated and signed by the reviewer. Pull the records through FastDriverScreening — same-day delivery from $40 (MVR Basic) per state, with the $60 MVR + CDLIS package satisfying the cross-state CDL requirement and $100 DOT Pre-Employment adding the FMCSA Clearinghouse pre-employment query mandated under §382.701(a).

3. Inquiry to Previous Employers

Within thirty days of the driver's placement on a CMV, you must investigate the driver's employment record for the prior three years (DOT-regulated employers) and document everything you found.

49 CFR §391.23(a)(2) and (d) — Investigation into the driver's employment history.

This includes verification of dates of employment, a copy of any drug and alcohol testing record under §40.25, accidents the driver was involved in, and any other DOT-regulated information the prior employer is required to disclose.

4. Driver's Road Test Certificate (or Equivalent)

Every driver must complete a road test administered by the carrier — or you must accept an equivalent in lieu of the test. The road test certificate goes in the file along with the form used during the test.

49 CFR §391.31 (road test) and §391.33 (equivalent of road test, e.g., a CDL or a road test certificate from a previous carrier within the last three years).

5. Medical Examiner's Certificate

The driver's federal medical certification, signed by a certified medical examiner, must be in the file. Long-form examination results are not required unless the driver received an exemption or variance.

49 CFR §391.43 (medical examination) and §391.41 (physical qualifications).

6. Medical Examiner's National Registry Verification

Carriers must verify that the medical examiner who signed the medical card is listed on the FMCSA National Registry of Certified Medical Examiners. Print or save the verification as part of the file.

49 CFR §391.23(m) — Verification of medical examiner's national registry status.

7. Driver's Certification of Compliance with Regulations

The driver signs an annual statement listing all violations of motor vehicle laws (other than parking) for the prior twelve months, even if they were not cited.

49 CFR §391.27 — Record of violations: the driver shall furnish a list of all violations annually, and the carrier shall retain the list in the qualification file.

8. Annual Review of Driving Record

Once a year, the carrier reviews the driver's driving record (the new MVR plus the §391.27 self-certification) and makes a written determination whether the driver remains qualified. The signed review goes in the file.

49 CFR §391.25 — Annual inquiry and review of driving record.

9. Subsequent Annual MVRs

Every twelve months, pull a new MVR and add it to the file. The MVR must be obtained from each state where the driver currently holds (or held in the prior year) an operator's license.

49 CFR §391.25(a) — At least once every 12 months, the motor carrier shall make an inquiry to obtain the motor vehicle record of each driver.

10. Documentation of Disqualifying Offenses

If at any point a driver becomes disqualified — by suspension, revocation, conviction of a serious offense, or any §383.51 disqualifying offense — you must remove them from CMV operation immediately and document the action in the DQ file.

49 CFR §391.15 — Disqualification of drivers.

11. Termination Documentation

When the driver leaves the carrier, document the date and reason for separation. Maintain the entire DQ file for three years from the date of termination per §391.51(d).

Filing order matters

Auditors do not just ask whether the documents exist — they ask whether they are in the order the regulation lists them and whether each is dated within the allowable window. A signed road-test certificate dated three months after the driver started operating the truck is itself a violation. Use the order above when you build each file, and file the documents chronologically within each section so the timestamps tell a coherent story.

A reusable template saves the headache

Building a §391.51 file from scratch every time a new driver comes on board is the single most common source of administrative violations during a compliance review. We package the same DQ file template our compliance team uses internally — fillable PDF plus editable Word — for $25 as a one-time, reusable purchase you can pair with any MVR order. The template covers every item above with the citations pre-filled and a reviewer signature block on each form, so you spend the onboarding meeting talking to the driver instead of rebuilding the paperwork.
