A driver qualification file must be kept for the duration of their employment plus three years under 49 CFR §391.51(d).
Drug and alcohol testing records don't follow that rule. They have their own, longer timeline under §382.401. Confusing these two timelines is a common recordkeeping mistake in FMCSA audits. Carriers sometimes delete drug and alcohol testing records when the DQF retention period ends, even though those records must be kept longer.
Keep every driver's complete DQF throughout employment and for three years after they are no longer employed by your company. The FMCSA can audit driver files belonging to former employees. Keep these records organized and accessible so they can be produced if requested during an audit.
49 CFR §382.401 governs D&A records, not §391.51. The timelines are independent and longer, for the most part.
| Record Type | Retention Period | Regulation |
|---|---|---|
| Verified positive test results | 5 years | §382.401(b)(1) |
| Alcohol test results ≥ 0.02 | 5 years | §382.401(b)(1) |
| Refusals to test | 5 years | §382.401(b)(1) |
| Negative and cancelled test results | 1 year | §382.401(b)(2) |
| Random selection records | 2 years | §382.401(b)(4) |
| Education and training records | Employment + 2 years | §382.401(b)(3) |
| Supervisor reasonable suspicion training | Employment + 2 years | §382.401(b)(3) |
| Annual MIS summary | 5 years | §382.401(b)(5) |
| SAP evaluation and RTD records | 5 years | §382.401(b)(1) |
| Clearinghouse query records | 3 years | §382.401(b)(4) |
One thing employers often miss: Drug and alcohol testing retention periods are based on the date the record was created, not the driver’s termination date. If a driver tested positive three months before leaving, that result has to be kept for five years from the test date.
“The most common retention mistake we see is carriers applying the 3-year DQF rule to drug and alcohol records. Those are separate regulations with separate timelines. Positive test results must be kept for five years regardless of when the driver left.”

The Clearinghouse does not replace your responsibility to retain documentation. You still need to retain documentation showing that required queries were conducted. Query results must be kept for three years from the query date, and pre-employment full queries and annual limited queries both fall under this.
The FMCSA can audit your files at any point within the driver file retention window. When they do, you may be required to produce the requested documents within a short timeframe, depending on the type of audit.
Remember, missing required documents or incomplete records may result in violations.
Here are some driver file document retention mistakes that FMCSA auditors find repeatedly:
Separate the driver qualification file and drug and alcohol testing retention in your system. Each one is regulated differently and follows different retention timelines. Don't use a single "destroy on" date for both.
Track retention timelines by document type. Driver qualification file records and drug and alcohol testing records follow different requirements, so they should not be assigned a single shared destruction date.
Put your retention policy in writing. If you can't explain your schedule to an FMCSA auditor, that raises questions about every file you've already destroyed.
Don't destroy anything during an active investigation. If you've received notice of a compliance review or enforcement action, keep all documentation until the matter is fully resolved, even if the standard window has technically passed.
For the complete document list for an active driver qualification file, see the DQF Checklist. Foley’s Dash platform helps track retention timelines at the document level, making it easier to manage records and avoid premature deletion. See how it works.
Three years after the driver's employment ends, per 49 CFR 391.51(d). Drug and alcohol testing records follow separate, longer retention periods under 49 CFR 382.401, with positive results and refusals requiring 5-year retention.
Verified positive test results and refusals must be kept for 5 years under 49 CFR 382.401. Negative and cancelled test results must be kept for 1 year. Education and training records must be kept for the duration of employment plus 2 years.
Premature destruction is a recordkeeping violation under 49 CFR 391.51. Each missing document is a separate violation during an FMCSA audit, affecting your SMS score and triggering enforcement action.
Yes. FMCSA accepts electronic records provided they are retrievable, reproducible, and protected against loss or tampering. The electronic system must produce any requested document within 48 hours of an FMCSA audit request.
Yes. If an owner-operator drives under your carrier authority, you must maintain and retain their DQF for the duration of service plus 3 years, under the same rules as any company driver per 49 CFR 391.51.
