Driver Qualification Files
What is a driver qualification file — and what has to be in it?
By the TenFour Compliance team · Published 2026-08-30 · Last reviewed August 30, 2026
A driver qualification file (DQ file) is the folder of records a motor carrier must keep proving each driver is qualified to operate a commercial motor vehicle. Federal rules spell out its contents. It is usually the first thing reviewed in an audit, because it is the clearest signal of whether a carrier runs organized.
Who needs one
Every carrier must keep a DQ file for every driver of a commercial motor vehicle that requires one — employees, leased drivers per the lease terms, and owner-operators on themselves. One truck does not exempt you: under your own authority, you are the carrier, and the carrier keeps the file.
What goes in the file
- The driver's employment application.
- An inquiry to each state where the driver held a license in the past three years — the motor vehicle record (MVR) pulled at hire.
- An updated MVR reviewed each year, with a note of that annual review.
- The road test certificate, or the equivalent accepted for CDL holders.
- The current medical examiner's certificate (the DOT medical card), and, where applicable, verification the examiner was listed on the National Registry.
- Safety performance history responses from previous DOT-regulated employers.
How long records are kept
As a general rule, DQ file materials are retained for as long as the driver is employed plus three years afterward. Some documents supersede each other (a new medical certificate replaces the old one), but do not purge aggressively — auditors care more about completeness than tidiness.
The mistakes small carriers actually make
- No file on the owner. The owner drives, but nobody opened a file on the owner.
- Missing annual MVR reviews — hired-in paperwork present, anniversaries missed.
- Expired medical certificates sitting in otherwise complete files.
- Records scattered across a glovebox, an email inbox, and a kitchen drawer — technically existing, practically unfindable.
None of these are exotic failures. They are what happens when the person responsible for the file is also driving 2,500 miles a week. The fix is a system that watches dates and chases documents — whether that system is a disciplined spreadsheet or a service.
TenFour builds and maintains DQ files — and chases the missing documents for you.
See the DQ file serviceFrequently asked
Is a DQ file the same as a personnel file?
No. Keep them separate. The DQ file holds the federally required qualification records; general employment paperwork (tax forms, payroll) belongs elsewhere, and mixing them makes audits slower and noisier.
Can DQ files be digital?
Yes — electronic records are acceptable when they remain accurate, accessible, and reproducible. Organized digital files are usually easier to produce in an audit than paper.
Who can pull the MVRs?
The carrier requests MVRs from state agencies, and services can do the pulling — but the carrier owns the obligation that they exist and are reviewed annually.
