What is a DQ file?
A Driver Qualification (DQ) file is the set of records a motor carrier must keep to prove a driver is legally qualified to operate a commercial motor vehicle. The contents are defined by 49 CFR §391.51, and the file must be kept for as long as the driver is employed plus three years after.
The DQ file is the first thing an FMCSA investigator opens, and the first thing a plaintiff's attorney subpoenas after a crash. It isn't a formality — it's the paper trail that shows you did your due diligence before putting a driver behind the wheel. Here's everything that belongs in it.
What §391.51 requires
Section 391.51 is the master checklist. Each item below is its own record with its own rule:
- Employment application (§391.21) — the driver's completed application, including the three-year address and employment history and the ten-year CDL employment history.
- Motor vehicle record (§391.23 / §391.25) — an MVR from each state that licensed the driver in the past three years, pulled at hire, then refreshed with a new MVR at least once a year.
- Road test or equivalent (§391.31 / §391.33) — a road-test certificate, or an acceptable substitute such as a valid CDL or a prior road-test certificate.
- Medical examiner's certificate (§391.43) — a current med card from a certified examiner, with verification against the National Registry of Certified Medical Examiners.
- Clearinghouse query records — for CDL drivers, the pre-employment full query and subsequent limited queries from the FMCSA Drug & Alcohol Clearinghouse.
- Safety-performance history — PSP data plus the previous-employer safety history for the last three years, with three documented good-faith attempts to reach each prior employer when they don't respond.
- Annual review & list of violations (§391.25 / §391.27) — the carrier's annual review of the driving record, and the driver's annual certification/list of any moving violations.
CDL vs non-CDL drivers
Both CDL and non-CDL drivers who operate CMVs under Part 391 need a DQ file — the core records are the same. The difference is scope: Clearinghouse queries and Part 382 random drug-and-alcohol testing apply to CDL drivers only. A good system scopes those automatically so a non-CDL driver isn't flagged for a rule that doesn't apply — and so a CDL driver isn't missing one that does.
How long to keep it
Keep the qualification file for the duration of employment plus three years after the driver leaves. Some records cycle while employed — the MVR and the annual review refresh yearly — but the file as a whole doesn't get thrown out the day someone quits.
Why the gaps matter
A hole in the DQ file is both an audit finding and a liability exposure. In a New Entrant audit or a compliance review, missing records are written up directly. In a negligent-hiring lawsuit after a crash, the same gap becomes the plaintiff's exhibit — proof you didn't verify what the regulations required. The file is cheap to keep complete and expensive to have incomplete.
Frequently asked questions
What regulation defines the DQ file?
49 CFR §391.51 lists the records a motor carrier must keep in each driver's qualification file. Related sections (§391.21, §391.23, §391.25, §391.27, §391.31, §391.43) define the individual records themselves.
Do non-CDL drivers need a DQ file?
Yes. Any driver of a commercial motor vehicle subject to Part 391 needs a DQ file, CDL or not. The difference is scope: CDL-only requirements like FMCSA Clearinghouse queries and Part 382 drug-and-alcohol testing don't apply to non-CDL drivers.
How long must a DQ file be kept?
The qualification file must be retained for as long as the driver is employed and for three years afterward. Individual records like the annual MVR and the annual review of driving record are kept on a rolling basis while the driver is employed.
What are the most common DQ-file gaps in an audit?
Missing annual MVRs, an expired or absent medical examiner's certificate, no annual review of driving record, no PSP report, and incomplete previous-employer safety history — especially missing documentation of the three good-faith attempts to reach a prior employer.
How FleetFalcon helps
FleetFalcon's Rapid Onboarding builds a complete §391 DQ file from a single link — capturing the application, consents, Clearinghouse and PSP authorizations, and running previous-employer checks with documented attempts. DocPulse then tracks every renewal — MVRs, medical cards, annual reviews — so the file stays complete for the whole employment-plus-three-years window instead of quietly developing holes.
