FMCSA Record Retention Requirements: How Long You Must Keep Every Document

FMCSA does not publish a single master retention schedule. Requirements are scattered across multiple regulations — driver qualification files in Part 391, drug testing records in Part 382, HOS records in Part 395, vehicle inspection records in Part 396, and accident registers in Part 390. Getting this wrong is how carriers accumulate violations during audits for records that no longer exist, or produce records that are incomplete because they don't know what to keep.

What the Regulation Actually Requires

The primary regulatory authorities for record retention are:

• 49 CFR § 391.51 — Driver qualification files: what must be in every DQF and how long to retain it
• 49 CFR § 382.401 — Drug and alcohol testing records: retention periods by record type
• 49 CFR § 395.8(k) — Hours of service and ELD records: 6-month retention for records of duty status and supporting documents
• 49 CFR § 396.3(c) — Vehicle inspection and maintenance records: retention for periodic inspections and repair records
• 49 CFR § 379.7 — General records: preservation of records in a form accessible to FMCSA

There is no single master schedule. Carriers must track retention requirements for each record type independently. The table at the bottom of this guide consolidates the key periods in one place.

Step-by-Step Practical Breakdown

Driver Qualification Files (DQF)

DQF requirements are at 49 CFR § 391.51. Each driver must have a complete DQF file maintained at the carrier's principal place of business. DQF documents must be retained for 3 years after the driver leaves the company. The DQF must contain:

• Application for employment (including last 3 years' employer list)
• Copy of current CDL
• Motor Vehicle Record (MVR) obtained before hire and annually thereafter
• Medical examiner's certificate (current and most recent prior)
• Road test certificate or equivalent (CDL skills test waiver)
• Certificate of violations (from driver, covering prior 12 months at hire)
• Prior safety performance history from employers in past 3 years
• Pre-employment drug test result
• Clearinghouse pre-employment query result

Drug and Alcohol Testing Records

Under 49 CFR § 382.401, testing records must be maintained by the carrier or C/TPA and are subject to varying retention periods based on record type:

• Positive drug or alcohol test results and refusals: 5 years
• Negative pre-employment drug test results: 1 year
• Return-to-duty test results and follow-up testing records: 5 years
• EBT calibration records and collection site documentation: 2 years
• SAP evaluation reports and treatment completion records: 5 years

Clearinghouse query records — pre-employment full queries and annual limited query authorizations — should also be retained for 3 years to match DQF retention, though FMCSA stores query history in the Clearinghouse system itself.

HOS and ELD Records

Under 49 CFR § 395.8(k), records of duty status — ELD records or paper logs — must be retained for 6 months. Supporting documents associated with the records of duty status (fuel receipts, toll records, bills of lading, dispatch records) must also be retained for 6 months. ELD data must be stored on the ELD device and backed up at the carrier's principal place of business.

Vehicle Inspection Records

Under 49 CFR § 396.3(c):

• Annual inspection reports (§ 396.17): 14 months from the inspection date — this ensures two consecutive years of reports are on file at any time
• Driver Vehicle Inspection Reports (DVIR, § 396.11): 3 months from the date the inspection was made
• Maintenance and repair records: Retained during the period the vehicle is in service and for 1 year after — though best practice is to retain for the vehicle's full service life

Accident Register

Under 49 CFR § 390.15, carriers must maintain an accident register for at least 3 years. The register must contain: date of accident, city or town, driver name, number of injuries, number of fatalities, whether hazmat spill occurred, and whether the vehicle was towed. Accident reports from police or other agencies should be attached to the register entry and retained for the same period.

Insurance Records

While FMCSA regulations do not specify a precise retention period for insurance documents, carriers should retain copies of MCS-90 filings, surety bonds, and insurance certificates for 3 years after policy expiration. This covers the general statute of limitations for most federal enforcement actions and provides documentation for any claims or audit inquiries related to past policy periods.

What Auditors Actually Look For

DQF completeness at hire: Auditors verify that all required documents were in the DQF before the driver's first day. A DQF missing the pre-employment drug test result, the MVR, or the prior employment safety history inquiry is deficient regardless of whether the driver has an otherwise clean record.

Annual MVR currency: The annual MVR must be obtained within 12 months of the prior review. Auditors calculate the gap between MVRs for each driver. A 13-month gap is a violation even if nothing changed on the driver's record.

HOS records vs. supporting documents: Auditors compare ELD logs to supporting documents — fuel receipts, weigh station records, tolls. When logs don't align with supporting documents, auditors investigate further and may cite falsification.

Destroyed or unavailable records: A carrier who says records were destroyed in a flood, fire, or computer failure — without having backups — faces the same violation as one who never created the records. FMCSA treats unavailable records as non-existent for audit purposes unless extraordinary circumstances are documented.

Record format: Under 49 CFR § 379.7, records can be maintained electronically if they are readily accessible, legible, and reproducible in a hardcopy format. Password-protected files that auditors cannot access on-site create the same problem as missing records.
