A driver qualification file (DQ file) is the set of records 49 CFR 391.51 requires a motor carrier to keep on every driver of a commercial motor vehicle, proving that driver is qualified to drive. This driver qualification file checklist lists every document the rule requires, when each one is due and how long to keep it. It is usually the first thing reviewed in an audit, because it is the clearest signal of whether a carrier is organized.
Who is required to have a DQ file
Every carrier must keep a DQ file for every driver of a commercial motor vehicle it uses: 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. It is not only for CDL drivers either; Part 391 covers drivers of commercial motor vehicles as 49 CFR 390.5 defines them, which starts at 10,001 pounds in interstate commerce.
Driver qualification file requirements, item by item
Section 391.51(b) lists eight items. Six are in place when the driver starts; two come due every year, and those two are where most files fall out of date.
| Document | Regulation | When it is due |
|---|---|---|
| Employment application | § 391.21 | Before the driver operates for you |
| Motor vehicle record from each state that licensed the driver in the past 3 years | § 391.23(a)(1), (b) | Requested, and in the file, within 30 days of hire |
| Road test certificate, or the CDL accepted in its place | § 391.31(e) / § 391.33 | Before the driver operates for you |
| Annual motor vehicle record | § 391.25(a) | Every 12 months |
| Note of your annual review of the driving record | § 391.25(c)(2) | Every 12 months |
| Medical examiner’s certificate, or the CDLIS record for CDL holders | § 391.43(g) / § 391.51(b)(7) | Before driving; renewed on the certificate’s own cycle |
| Note verifying the medical examiner on the National Registry | § 391.23(m) | At hire and with each new certificate |
| SPE certificate or medical exemption, where one applies | § 391.49 / Part 381 | While it is in effect |
How long records are kept
Keep each driver's file for as long as the driver works for you and for three years after (49 CFR 391.51(c)). A few items may come out sooner: the annual motor vehicle records, the notes of the annual reviews, medical certificates, medical variances and the National Registry verification notes can be removed three years after they were made (391.51(d)). 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 glove box, 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 driver qualification file management done for you.
