Driver Qualification File Checklist (49 CFR 391.51), Including Owner-Operators

Updated October 2026 · Citations: 49 CFR · Educational, not legal advice. Not affiliated with FMCSA/USDOT.

A missing driver qualification (DQ) file is a critical violation in new entrant audit scoring, and so are a missing hiring MVR and a missing medical certificate (Appendix B to Part 385, VII). Several automatic-failure items also come down to what's in this file. Here is everything 49 CFR Part 391 requires, in the order you'll collect it, plus the twist for owner-operators.

Who needs a DQ file

Every motor carrier must keep a DQ file for each driver it employs (§ 391.51(a)). It may be combined with the personnel file. That includes part-time drivers, occasional drivers, and you.

Owner-operators: under the FMCSRs, the "employer" includes a person who owns or leases a CMV and operates it in their business (§ 390.5), and the drug and alcohol rules say an employer who employs himself or herself must meet both the employer and the driver requirements (§ 382.103(b)). In practice, a one-truck company needs a complete file on the owner. Auditors ask for it, and "I'm the only driver" is not an exemption.

First, is the driver qualified?

Before the paperwork, the basic qualifications in § 391.11(b). For interstate driving, a driver must:

be at least 21 years old;
read and speak English well enough to converse with the public, understand highway signs, respond to official inquiries and make entries on reports;
be able to safely operate the vehicle by reason of experience or training;
be physically qualified under § 391.41 and have a current medical certification;
have only one valid commercial motor vehicle operator's license;
not be disqualified under § 391.15; and
have completed a road test or presented an accepted equivalent (§§ 391.31, 391.33).

The DQ file checklist

Before the driver's first trip

Employment application with every item in § 391.21: name, address, date of birth, SSN; addresses for the past 3 years; every unexpired CMV license or permit; driving experience by equipment type; accidents and traffic convictions in the past 3 years (or "none"); any license denial, suspension or revocation; employers for the past 3 years, and for CDL drivers, CMV employers for the 7 years before that; and the driver's signature and date.
Road test certificate (§ 391.31), or a copy of a CDL or prior road test certificate you accept as equivalent (§ 391.33). If you're the carrier and driver, someone else must give the road test (§ 391.31(b)).
Medical certification (§§ 391.41, 391.43, 391.51(b)(6)). See the next section.
Clearinghouse pre-employment full query with the driver's electronic consent, for CDL drivers (§ 382.701(a)). Keep the result with the file or with your drug and alcohol records.
Pre-employment drug test negative result before any safety-sensitive work, for CDL drivers (§ 382.301). This is usually kept with drug and alcohol records rather than in the DQ file, but it must exist.

Within 30 days of hire

MVR from every state where the driver held a license or permit in the past 3 years (§ 391.23(a)(1), (b)), or a note documenting your good-faith effort if a state didn't respond.
Safety performance history from DOT-regulated employers in the past 3 years (§ 391.23(a)(2)), including drug and alcohol history for CDL drivers, and a record of each employer contact and response. Keep a copy of what you received, or a note of your good-faith effort.

Every 12 months

Annual MVR from each state where the driver holds a license (§ 391.25(a)).
Annual review note: a dated, signed note that you reviewed the driving record to see if the driver meets the minimum requirements for safe driving or is disqualified, with the reviewer's name (§ 391.25(b)–(c)).
Annual Clearinghouse query for CDL drivers (§ 382.701(b)), kept with your drug and alcohol records.

Whenever it expires

New medical certification before the old one runs out; no longer than 24 months, and the examiner may set a shorter period (§ 391.45).
CDL renewal and current endorsements (§ 383.23).

Medical certification: what goes in the file now

Driver type	What to keep	Rule
CDL / CLP holders	The CDLIS MVR from the current licensing state showing medical certification status. Under rules effective June 23, 2025, CDL and CLP drivers no longer need to carry the paper certificate, and the electronic status controls if there's a conflict.	§ 391.51(b)(6)(ii); § 391.41(a)(2); § 391.23(m)(2)
Non-CDL CMV drivers (e.g. 10,001–26,000 lbs)	Original or copy of the medical examiner's certificate, plus a note verifying the examiner was on the National Registry of Certified Medical Examiners on the date issued.	§ 391.23(m)(1); § 391.51(b)(6)(i), (b)(8)(i)
Any driver with a variance	A copy of the FMCSA medical variance (exemption letter or Skill Performance Evaluation certificate).	§ 391.51(b)(6)(iii), (b)(7)

Knowingly using a physically unqualified driver is an automatic audit failure (§ 385.321, item 12 on our auto-fail list). Track every expiration date.

How long to keep it

Keep each DQ file for as long as the driver works for you and for three years after they leave (§ 391.51(c)). Some items may be removed three years after their date of execution even while the driver is still employed: annual MVRs and review notes, medical certificates and verification notes, and certain variance documents (§ 391.51(d)). The application, the hiring MVRs, the employer history and the road test stay for the life of the file.

Records may be kept electronically if they're accurate, legible and can be produced on request; FMCSA may ask for records at your principal place of business, and for offsite audits you'll upload them to NEWS.

Owner-operator walkthrough: a file on yourself

If it's just you, the file is short, but every piece still has to exist:

Fill out an employment application on yourself, covering every § 391.21 item. Sign and date it.
Order your own MVR from every state you held a license in during the past three years and file it.
Complete the previous-employer history for any DOT-regulated employers you drove for in the past three years. If you were never employed as a driver, write a dated note saying so.
Have someone else give you a road test, or accept your valid CDL as equivalent under § 391.33, and file the certificate or a copy of the license.
File your CDLIS MVR showing medical status (CDL) or your medical card plus registry verification (non-CDL).
For CDL operations: run your pre-employment Clearinghouse full query on yourself, through your designated C/TPA setup, before your first trip.
Set calendar reminders 30 days before your annual MVR, annual review and medical expiration.

Mistakes auditors find most often

MVRs pulled only from the current state, missing a state the driver held a license in during the past three years.
Annual review note missing a date, a signature or the reviewer's name.
Applications missing the 3-year (or 10-year for CDL) employment history.
Expired medical certification, or a non-CDL card with no registry verification note.
No file at all on the owner.

The DQ file is one of six areas the auditor reviews. See the full new entrant audit checklist for the others.

When you add your first employee driver

Run the whole checklist again for that person before their first trip, and add the drug and alcohol steps: a negative pre-employment result, a full Clearinghouse query with their consent, previous-employer testing history, and their name on your consortium roster. Hand them your written policy and get a signed receipt. Then put their MVR, review and medical dates in the same tracker as yours.

Frequently asked questions

Do owner-operators need a driver qualification file on themselves?

Yes. A motor carrier must keep a DQ file for each driver it employs (49 CFR 391.51), and under the FMCSRs a person who operates their own CMV in their business is both employer and driver (49 CFR 390.5). A one-truck company needs a complete DQ file on the owner.

How long do I keep a DQ file?

Keep the DQ file for as long as the driver works for you and for three years afterward. Certain items, such as old MVRs, annual reviews and medical certificates, may be removed three years after their date of execution (49 CFR 391.51(c)–(d)).

Do CDL drivers still need a paper medical card in the DQ file?

Under rules effective June 23, 2025, CDL and CLP holders no longer need to carry the paper certificate; the carrier keeps the CDLIS MVR showing the driver's medical certification status, and the electronic status controls. Non-CDL CMV drivers still need the medical examiner's certificate on file plus National Registry verification.

Can I give myself the road test?

No. A driver who is also the motor carrier must be given the road test by someone else (49 CFR 391.31(b)). Alternatively, you may accept a valid CDL as equivalent to the road test where 49 CFR 391.33 allows it.
