DOT Record Retention Requirements: How Long to Keep Every Document (And What Happens If You Can't Produce Them)
Every document you couldn't produce during an audit is treated as if the underlying compliance requirement was never met. Here's what you're required to keep, for how long, and what happens when the files aren't there.
Why Record Retention Is a Compliance Issue
When you can't produce a required record, the legal presumption is that the required activity didn't happen. You don't get credit for things you actually did if you can't prove it.

Driver Qualification Files (DQF)
The driver qualification file must be maintained for every CDL and non-CDL driver operating a CMV for your operation under 49 CFR § 391.51.
| DQF Document | Retention Period |
|---|---|
| Driver application | Duration of employment + 3 years |
| Motor vehicle record (MVR) | Duration of employment + 3 years |
| Annual review of driving record | Duration of employment + 3 years |
| Medical examiner's certificate (current) | Duration of employment |
| Previous employer inquiry responses | Duration of employment + 3 years |
| Road test certificate or equivalent | Duration of employment + 3 years |
| Clearinghouse pre-employment query | Duration of employment + 3 years |
“Duration of employment + 3 years” means 3 years after the driver leaves your operation. See driver qualification file requirements for a complete guide to what belongs in the DQF.
Hours of Service Records
Under 49 CFR § 395.8(k):
| Record Type | Retention Period |
|---|---|
| Driver's Records of Duty Status (RODS/logs) | 6 months |
| Supporting documents (fuel receipts, toll records, dispatch records) | 6 months |
| ELD data (electronic records) | 6 months |
| Time records (short-haul exemption) | 6 months |
Also important: ELD data must be transferable and accessible for the full 6-month period. Data that can't be retrieved from your ELD system is treated the same as missing records.
Vehicle Inspection Records
- Annual inspection report (49 CFR § 396.21): 14 months from date of inspection
- Inspector qualification documentation: 14 months from date of inspection
- Post-trip driver vehicle inspection reports (49 CFR § 396.11): 3 months
- Vehicle maintenance records (49 CFR § 396.3): Duration of vehicle operation + 1 year
Drug and Alcohol Testing Records
Under 49 CFR § 382.401:
| Record Type | Retention Period |
|---|---|
| Positive drug test results | 5 years |
| Alcohol test results ≥ 0.02 BAC | 5 years |
| Refusals to test | 5 years |
| SAP evaluation and follow-up records | 5 years |
| Negative pre-employment test results | 1 year |

Common Recordkeeping Mistakes
- Destroying DQFs too soon. The retention period is 3 years post-employment — not 3 years from hire.
- Not keeping negative drug test results. Negative tests only need to be kept 1 year, but many carriers don't keep them at all.
- Losing records when switching systems or software. Export and archive all historical records before retiring a system.
- Not organizing records by driver and vehicle. Records dumped into folders by date rather than organized by driver make it impossible to quickly produce what auditors request.
- No backup system. Cloud backup of digital records and off-site storage for physical records are basic risk management steps.
Frequently Asked Questions
Can I keep records digitally instead of in paper files?
Yes. FMCSA allows digital recordkeeping as long as records are readable, printable, and accessible to FMCSA officials upon request. Digital records must be backed up and maintained in a format that can be produced at the time of inspection or audit.
What if my ELD company goes out of business?
You are responsible for maintaining accessible records regardless of what happens to your ELD provider. Download and archive your HOS data periodically.
If a driver returns after a gap in employment, do I need a new DQF?
Yes. A driver who leaves and returns is treated as a new hire for DQF purposes. You need a new employment application, new MVR, new pre-employment drug test, new Clearinghouse query, and updated physical if the prior medical certificate has expired.
How long do I need to keep vehicle records after I sell the truck?
Vehicle maintenance records must be kept for 1 year after the vehicle leaves your operation.
