Quick checklist
- Create a DQ file for each driver before dispatch.
- Use 49 CFR 391.51 as the control list for core DQ file contents and retention.
- Save the driver application and three-year employment history verification.
- Keep required MVR and safety performance inquiries where applicable.
- Track medical qualification documents and note the expiration date on the file jacket.
- Complete and save annual review materials, including the MVR pull and a dated review note.
- For CDL drivers subject to Part 382, file the pre-employment drug test result and Clearinghouse query record.
- Confirm the road test or qualifying substitute is documented under 49 CFR 391.31 where required.
Why this matters
A DQ file shows that the carrier verified the driver was qualified to operate before dispatch. Under 49 CFR 391.51, most file items must be kept for three years after the driver leaves, so onboarding gaps do not disappear — they surface during the next audit. Auditors work through files driver by driver, checking that required items exist and that ongoing requirements like the annual MVR and annual review are current. The most common pattern that causes findings is solid initial onboarding with annual requirements skipped after the first year.

Common gaps
- A file has the license and medical card but no driver application.
- Annual review was completed the first year and skipped every year after.
- MVRs are downloaded and saved but not paired with a review note showing someone looked at them.
- Medical certificate is on file but expired, with no renewal copy added when it came in.
- Annual MVR was pulled from the state system but not printed or filed with a review note.
- Drivers who transferred between company divisions have no DQ file at the current operating location.
- Former driver files were deleted rather than archived before the three-year retention period ran.
Before / During / After audit
Before
- Review every active and in-scope former driver.
- Use the same document order for each file so gaps are easy to spot.
- Mark missing annual items separately from onboarding items.
During
- Provide files driver by driver on request.
- Keep notes when a record is stored in a state licensing portal or external vendor system.
After
- Schedule recurring annual reviews on a calendar with driver name and due date.
- Archive former driver files in a consistent location with the hire and separation date labeled.
- Update the onboarding checklist to reflect any new items identified during the audit.
FAQ
Does Part 391 apply to non-CDL drivers operating lighter commercial vehicles?
Most Part 391 requirements apply to drivers operating commercial motor vehicles as defined under federal rules, not just CDL holders. Some requirements are CDL-specific, but the driver application, road test, annual MVR, medical qualification, and annual review requirements apply broadly to drivers in CMVs above the applicable weight threshold. Review 49 CFR Part 391 for your specific operation.
How long do DQ files need to be kept after a driver leaves?
Three years from the driver's last day is the standard for most items — the application, MVR records, road test certificate, annual review documents. A few items run longer: the driver's certificate of violations, for example, is kept for the duration of employment plus three years. The practical problem is that carriers often deactivate driver accounts in payroll the same week someone leaves, and the DQ records disappear with the account. Keeping a separate archive folder by driver name and separation date, outside the active HR system, avoids that.
What makes an annual driving record review complete for audit purposes?
Pulling an MVR is only half the requirement. The regulation also requires a written determination that the carrier reviewed the record and decided the driver still qualifies. What gets cited in audits is a file that has the MVR but nothing else — no date, no reviewer name, nothing showing the record was actually reviewed. It does not take a formal document: a signed note with the date and the reviewer's identity, stored next to the MVR in the driver's file, satisfies the requirement. The note in a separate spreadsheet or an email thread is harder to present cleanly during a review.
