FMCSA Driver Qualification File: Checklist, Maintenance, and Retention

Every motor carrier running commercial motor vehicles in interstate commerce must keep a Driver Qualification (DQ) file on each driver, and the FMCSA driver qualification file requirements under 49 CFR 391.51 spell out exactly what has to be inside it: the employment application, motor vehicle records from hiring and every year after, a road test certificate or an equivalent CDL copy, the driver’s current medical examiner’s certificate, an annual review note, and, when they apply, medical variance documents and a National Registry verification note. Getting the initial file right is only half the job; the other half is a 12-month maintenance cycle and a retention rule that keeps records on hand for three years after a driver leaves.¹

The Full DQ File Checklist

Section 391.51 lists every document the file must contain. Missing any one of them is a citable violation during a compliance review.

The completed and signed employment application required by 49 CFR 391.21.
The initial motor vehicle record from each state where the driver held a license during the preceding three years, pulled as part of the pre-employment inquiry under 49 CFR 391.23.
A road test certificate issued under 49 CFR 391.31, or a copy of a valid CDL accepted as equivalent under 49 CFR 391.33.
The annual MVR from each state where the driver is licensed, pulled at least once every 12 months.
A written annual review note showing who reviewed the MVR and when.
The original or a legible copy of the medical examiner’s certificate. For CDL holders, a CDLIS motor vehicle record showing current medical certification status satisfies the requirement.
Any applicable medical variance documentation, such as a Skill Performance Evaluation (SPE) certificate or a medical exemption letter.
For non-CDL drivers, a note documenting that the carrier verified the medical examiner is on the National Registry of Certified Medical Examiners.

What the Employment Application Must Cover

The application is not a generic hiring form. Under 49 CFR 391.21, it must collect the driver’s name, address, date of birth, and Social Security number; every address for the preceding three years; every employer for the preceding three years, plus an additional seven years of any employer where the applicant operated a commercial motor vehicle; every accident during the preceding three years, with dates, descriptions, and injury or fatality information; and every traffic conviction or forfeited bond (excluding parking) during the preceding three years. The driver has to sign it.²

Off-the-shelf application templates that skip required fields are one of the more common audit findings. Building the form directly from the regulation is safer than trusting a vendor’s version.

Pre-Employment Investigations

Within 30 days of a driver’s start date, the carrier has to complete two separate investigations. The first is the state MVR inquiry covering every jurisdiction that issued the driver a license or permit in the past three years. The second is a safety performance history request sent to every DOT-regulated employer from the past three years, covering accident records and any drug or alcohol testing violations. Previous employers have 30 days to respond. When they don’t, the carrier must document its good-faith contact attempts, including names, addresses, dates of contact, and what was received.³

Keep the Driver Investigation History File Separate

The responses from previous employers do not go in the DQ file. They go in a separate Driver Investigation History File (DIHF) governed by 49 CFR 391.53, because they contain sensitive drug and alcohol testing information. Access is limited to people involved in the hiring decision and, for non-drug-and-alcohol content, the carrier’s insurer. The DIHF must also hold the driver’s written authorization allowing the carrier to request substance-abuse history, plus copies of all responses received or documentation of contact efforts. Retention matches the DQ file: employment plus three years after separation.⁴

Medical Certification

A driver cannot operate a commercial motor vehicle without a current medical examiner’s certificate issued by an examiner listed on the National Registry. Under 49 CFR 391.45, recertification is required at least every 24 months, and certain health conditions cause the examiner to issue a shorter-term certificate. The expiration date printed on each certificate is what governs; a driver operating on an expired certificate is an automatic out-of-service violation.⁵⁶

Drivers with a limb impairment may qualify for a Skill Performance Evaluation certificate under 49 CFR 391.49. An SPE certificate is valid for up to two years and must be renewed with updated medical information and a driving record for the certificate period. A copy of the current SPE certificate goes in the DQ file.⁷

Road Test or Equivalent

Before a driver runs revenue work, the carrier must document technical proficiency. The default is a carrier-administered road test under 49 CFR 391.31, resulting in a signed certificate for the file. Most carriers instead rely on the equivalent under 49 CFR 391.33: a valid CDL that, under the issuing state’s rules, required a road test in the same type of vehicle the carrier plans to assign. A copy of that CDL satisfies the requirement. A road test certificate issued by another carrier within the preceding three years also qualifies.⁸

Drug and Alcohol Clearinghouse Queries

Since January 2020, carriers must run a full pre-employment query in the FMCSA Drug and Alcohol Clearinghouse before letting a new driver perform any safety-sensitive function. A full query requires the driver’s specific written consent and returns detailed violation records. If an unresolved violation appears, the driver cannot be put to work until they finish the return-to-duty process.⁹

After hiring, the carrier must query the Clearinghouse at least once every 12 months for every driver subject to drug and alcohol testing. This annual check can be a limited query, which only indicates whether information exists in the database. The driver must give general consent before a limited query is run. If a limited query shows information exists, the carrier has 24 hours to run a full query, and failing to do so means the driver has to be pulled from safety-sensitive duties.⁹

General-consent records for limited queries must be retained for three years. The Clearinghouse keeps a history of every query, so an active employer registration satisfies the recordkeeping requirement for query results. Carriers are not required to file copies of results in the DQ file, though many do for audit convenience.¹⁰

The 12-Month Maintenance Cycle

Three recurring tasks keep each file compliant.

Annual MVR Inquiry

Pull a fresh MVR from every state where the driver holds a license or permit. Unlike the pre-employment MVR, the annual only needs to cover the preceding 12 months.¹¹

Driver’s Annual Violation Certification

Each driver must give the carrier a written list of every traffic conviction or forfeited bond (excluding parking) from the preceding 12 months. Drivers with no violations still have to certify that fact in writing. This self-report is compared against the state MVR to catch discrepancies.

Annual Driving Record Review

A designated safety official reviews the annual MVR alongside the driver’s self-report and decides whether the driver still meets minimum qualifications. The reviewer’s name and the review date must be documented. A license suspension, a disqualifying offense under 49 CFR 391.15, or an unreported violation on the MVR requires immediate action.¹¹¹²

Retention Timelines

The overall rule: keep the DQ file for the entire time a driver is employed plus three years after separation. The three-year clock runs from the date of separation.¹

Certain recurring documents follow a rolling schedule and may be removed from the file three years after the date they were executed:

Annual motor vehicle records from the 391.25(a) inquiry.
The annual review note required by 391.25(c)(2).
Medical examiner’s certificates, or the CDLIS MVR showing certification status for CDL holders.
Medical variance documents, including SPE certificates and medical exemption letters.
The note verifying the medical examiner’s National Registry listing.

For long-tenured drivers, this rolling purge keeps files from growing indefinitely. Carriers using digital systems often retain everything rather than risk purging a document still within its retention window. There is no penalty for keeping records longer than required.¹

Multiple-Employer Drivers Follow Different Rules

If a driver is regularly employed by another motor carrier, 49 CFR 391.63 relieves the second carrier of the full DQ file requirements. No employment application, no pre-employment investigations, and no annual MVR inquiry and review are required. The carrier must still record and retain the driver’s name, Social Security number, and CDL information (number, type, and issuing state) before letting the driver operate, and must keep that information for three years after the driver stops working for the carrier.¹³

Producing Files During an Audit

Files can be kept as paper, electronic records, or a mix. Digital systems make it easier to track medical certificate expirations and annual review deadlines, but format is the carrier’s choice. Access must be restricted to authorized personnel, and the DIHF in particular has explicit access limits because of the drug and alcohol testing history it contains.

When an FMCSA special agent or representative requests records, the carrier must produce them within 48 hours, excluding Saturdays, Sundays, and federal holidays. A Friday afternoon request effectively runs until the following Wednesday. Files stored at a regional office or a driver work-reporting location must still be delivered to whatever location the agent specifies within that window. Electronic files must be legible on screen or when printed.¹⁴
