Keep the whole driver qualification file while the driver works for you and for 3 years after (391.51(c))

What does FMCSA check in a DOT compliance review?
FMCSA rates six factors in a compliance review. They are general (Parts 387 and 390) and driver (382, 383 and 391). They are also operational (392 and 395) and vehicle (393 and 396). The last two are hazardous materials and the accident rate. Each factor comes out Satisfactory, Conditional or Unsatisfactory. Two or more Unsatisfactory factors make the whole rating Unsatisfactory. Keep records sorted by category, not just by driver, so you can hand over what an auditor asks for fast.
- Build a driver file for every driver: application, license check, road test, medical certificate and annual MVR review.
- Keep hours-of-service records (ELD data or logs) and supporting documents for at least 6 months.
- Keep vehicle maintenance records for 1 year where the truck is housed or maintained, and for 6 months after it leaves your control. Keep each annual inspection report for 14 months.
- Keep drug and alcohol testing records on file: pre-employment, random, and any post-accident or reasonable-suspicion tests.
- Keep your accident register ready. Sort everything by the six rating factors before an audit, not during one.
| Area | What it covers |
|---|---|
| Driver qualification | Applications, licenses, medical certificates, road tests, annual MVR reviews |
| Hours of service | ELD or paper logs, supporting documents, 6-month retention |
| Vehicle maintenance | Annual inspections, repair records, driver vehicle inspection reports |
| Drug and alcohol testing | Pre-employment, random, post-accident and reasonable-suspicion test records |
| General recordkeeping | Accident register, insurance filings and other required records |
A compliance review can end in a Satisfactory, Conditional or Unsatisfactory rating. An Unsatisfactory rating can lead to an out-of-service order. This checklist follows FMCSA's own review categories, not a private company's scoring system.
