The Driver Qualification File is the single most-checked record in a DOT audit — and the most common place carriers fall short. A missing medical card, a skipped annual MVR review, or an incomplete application is enough to turn an otherwise-clean review into findings. This guide breaks down exactly what a DQF requires, how long to keep it, and how to keep every file audit-ready.
What is a Driver Qualification File?
A Driver Qualification File (DQF) is the record a motor carrier must keep for every driver who operates a commercial motor vehicle, defined under 49 CFR §391.51. It is the documented proof that the driver is legally qualified to drive — properly licensed, medically certified, screened, and reviewed. Carriers must maintain a DQF for each driver and keep it current throughout employment.
What's inside a DQF
At a minimum, a compliant DQF contains:
- The employment application (§391.21) — the driver's address and employment history, accidents, violations, and license information.
- Safety performance history inquiries (§391.23) — records of your investigation into the driver's previous DOT-regulated employers from the past three years.
- The Motor Vehicle Record (MVR) obtained at hire, plus the annual MVR review (§391.25) confirming the driver still meets standards.
- The road test certificate (§391.31) — or a CDL or equivalent certificate accepted in place of the road test (§391.33).
- The medical examiner's certificate (MEC) (§391.43) from a certified examiner on the National Registry, kept current.
Closely related screenings — the FMCSA Clearinghouse query and the pre-employment drug test — are required to hire, but are typically retained in separate, confidential files rather than inside the DQF itself.
How long to keep a DQF
| Record | Retention |
|---|---|
| The Driver Qualification File (overall) | Length of employment + 3 years |
| Annual MVR + annual review | 3 years |
| Safety performance history inquiries | 3 years from date of hire |
| Medical examiner's certificate | Keep current; retain per DQF rules |
Always verify against the current FMCSA regulations, which can change.
Do owner-operators need a DQF?
Yes. If a driver operates a CMV under your authority — employee or leased owner-operator — you are responsible for maintaining their DQF. The requirements scale down for very small operations, but the core file still applies. Getting this right from the first hire is part of streamlining driver onboarding.
Common DQF mistakes auditors catch
- Expired medical cards — the single most common finding. The driver is technically out of qualification the day it lapses.
- Missing or late annual MVR reviews — the MVR was pulled but never reviewed and documented.
- Incomplete applications — gaps in employment history or unsigned sections.
- No previous-employer safety history inquiry on record.
- Files scattered across email, drives, and paper — so nothing can be produced quickly during an audit.
Your DQF checklist
- Completed, signed employment application on file
- Safety performance history inquiries to prior employers documented
- MVR at hire + a documented annual MVR review for each year
- Road test certificate or accepted CDL equivalency
- Current medical examiner's certificate (verified on the National Registry)
- Pre-employment drug test + Clearinghouse query (separate file)
- Expiration alerts set for the medical card, MVR review, and license
- Everything stored together, retained per the rules, and producible on demand
How Fleetive keeps DQFs complete
Fleetive builds a complete DQF for every driver and never lets it drift: documents are collected during onboarding, organized in audit-ready folders, and watched with expiration alerts so a medical card or annual review never slips. When an audit comes, you export a complete file in seconds — see managing DQFs for a closer look.
