Hiring a commercial driver is not the same as hiring for most other roles. Carriers that operate commercial motor vehicles are regulated by the Federal Motor Carrier Safety Administration, and federal rules spell out exactly what has to go into a driver’s file before that person gets behind the wheel. Layered on top of those federal driving rules is the Fair Credit Reporting Act, which governs how a carrier can use a background check company to pull records. Getting both pieces right matters for safety and for avoiding compliance exposure.
The driver qualification file is the foundation
Under 49 CFR Part 391, every motor carrier subject to the Federal Motor Carrier Safety Regulations must keep a driver qualification file for each driver. That file generally has to include the driver’s employment application, a road test certificate or equivalent, the medical examiner’s certificate, and the results of the safety performance history investigation described below. The qualification file is not optional paperwork. It is the record a carrier would have to produce in a roadside audit or compliance review.
Safety performance history: the three year look back
Part 391 also requires carriers to investigate a driver’s safety performance history with previous DOT regulated employers going back three years. Under 49 CFR 391.23, this investigation covers the driver’s general employment history and specifically requires the hiring carrier to request records from prior employers about any safety sensitive drug and alcohol testing violations. The same section requires an inquiry into the driver’s driving record, meaning the carrier has to obtain a motor vehicle record, often called an MVR, from every state where the applicant held a license in the preceding three years.
Annual MVR review is a separate, ongoing duty
The pre employment MVR pull is not the only time a carrier has to look at driving history. 49 CFR 391.25 requires motor carriers to request a current MVR for each driver at least once every twelve months and to review it against the driver qualification standards in Part 391, including disqualifying violations and point totals. A driver who picks up a serious moving violation or a suspension after being hired does not stay invisible until the next hiring cycle. The annual review exists so carriers catch that change in real time.
The FMCSA Drug and Alcohol Clearinghouse
Before a carrier can let a new CDL holder perform a safety sensitive function, federal rule requires a query of the FMCSA Drug and Alcohol Clearinghouse to check whether the driver has an unresolved drug or alcohol violation on record. The Clearinghouse is a national database that tracks violations under Part 382, and carriers must also run a query at least once a year for every currently employed CDL driver. A driver with an unresolved violation in the Clearinghouse cannot legally be put behind the wheel of a commercial motor vehicle until they complete the return to duty process.
Controlled substances and alcohol testing
The testing program itself is governed by two federal rules working together. 49 CFR Part 382 sets out which drivers must be tested, the testing events (pre employment, random, reasonable suspicion, post accident, return to duty and follow up), and consequences for a positive result or refusal to test. 49 CFR Part 40 governs the procedures the laboratory, collector and medical review officer must follow for any DOT regulated test, regardless of which mode of transportation it applies to. A CDL driver cannot start safety sensitive work until a verified negative pre employment result is on file, as required under Part 382.
Medical certification
CDL drivers also have to be physically qualified to drive. Subpart E of Part 391 lists the physical qualification standards, and Subpart D covers the medical examination and certification process, including the requirement that the exam be performed by a medical examiner listed on the National Registry of Certified Medical Examiners. A current medical certificate has to be part of the qualification file, and carriers should confirm it has not expired rather than relying on the driver’s word.
Criminal history and the hazmat endorsement
Federal motor carrier rules do not themselves require a criminal background check for every CDL driver. Carriers commonly run one anyway as part of their own hiring standards, and state law may require it for certain cargo or passenger endorsements. The one federally mandated criminal and security screen applies to drivers seeking a hazardous materials endorsement, which requires a Transportation Security Administration threat assessment that includes a fingerprint based criminal history records check. Details on that process are explained in our guide to hazmat endorsement background checks. Outside the hazmat context, whether a general criminal history check is required, and what it may show, depends on the state and the carrier’s own policy, so carriers should not assume a uniform national rule exists. Some states also run their own fingerprint based checks for passenger carrier endorsements or school bus operation, and carriers operating across state lines should confirm the rule in each state where they license drivers rather than assuming the same standard applies everywhere.
Owner operators and leased drivers are not exempt
The driver qualification requirements in 49 CFR Part 391 apply to the motor carrier operating the commercial motor vehicle, not only to drivers classified as employees. A carrier that leases equipment and a driver from an owner operator, or that uses an independent contractor, still has to maintain a qualification file, obtain the safety performance history, and meet the drug and alcohol testing obligations for that driver before dispatch. Treating a contractor relationship as a reason to skip the file is a common and costly misunderstanding of the rule.
What a compliant screening package typically includes
| Check | Who requires it | Typical source |
|---|---|---|
| Driver qualification file | FMCSA, 49 CFR 391 | Carrier’s own records |
| Three year safety performance history, including MVR | FMCSA, 49 CFR 391.23 | State licensing agencies, prior DOT employers |
| Annual MVR review | FMCSA, 49 CFR 391.25 | State licensing agencies |
| Clearinghouse query (pre employment and annual) | FMCSA, 49 CFR 382 | FMCSA Clearinghouse |
| DOT drug and alcohol testing | FMCSA, 49 CFR Part 40 and 382 | DOT certified laboratory, MRO |
| Medical certification | FMCSA, 49 CFR 391 Subparts D and E | Certified medical examiner |
| Hazmat threat assessment | TSA, where a hazmat endorsement is sought | TSA fingerprint based check |
| General criminal history check | Varies by state and carrier policy | State or county court records, where applicable |
How the FCRA fits in
When a carrier uses a third party background check company, such as a consumer reporting agency, to pull a criminal history report or an MVR, that report is a consumer report under the Fair Credit Reporting Act. That means the carrier must provide a standalone disclosure to the applicant and get written authorization before ordering the report. If information in the report leads the carrier to consider not hiring the applicant, the carrier generally must send a pre adverse action notice with a copy of the report and a copy of the Summary of Rights, give the applicant a reasonable amount of time to respond, and then send an adverse action notice if the decision stands. These duties apply in addition to, not instead of, the FMCSA requirements described above. A background check company can help a carrier assemble the required records, but it does not replace the carrier’s own duty to maintain the driver qualification file.

Frequently asked questions
Does federal law require a criminal background check for every CDL driver?
No. Federal motor carrier rules require the driver qualification file, safety performance history, MVR checks, Clearinghouse queries and drug and alcohol testing. A general criminal history check is not mandated by FMCSA for every driver. It may be required by state law for certain endorsements or by the carrier’s own hiring policy.
How far back does the MVR and employment history check go?
The safety performance history investigation under 49 CFR 391.23 covers the three years before the application date. Separately, carriers must pull a current MVR for each driver at least once every twelve months while employed, under 49 CFR 391.25.
What is the FMCSA Clearinghouse and when is it checked?
The Clearinghouse is a national database of drug and alcohol program violations for CDL holders. Carriers must query it before allowing a new driver to perform safety sensitive functions and at least annually for current drivers, consistent with Part 382 requirements.
Does a hazmat endorsement require extra screening?
Yes. A driver applying for a hazardous materials endorsement must undergo a TSA security threat assessment, which includes a fingerprint based criminal history records check, in addition to the standard driver qualification process.
Who has to send the pre adverse and adverse action notices?
The carrier, as the user of the consumer report, has that duty under the FCRA when a background check company supplies the report. The background check company is not the one who decides whether to hire, and it generally is not the one that sends these notices.
Can a carrier skip the driver qualification file if it uses a background check company?
No. The driver qualification file requirement in 49 CFR Part 391 belongs to the motor carrier regardless of which vendor or background check company is used to gather supporting records.
Reveal Background helps employers build compliant screening programs for safety sensitive hiring, including driver qualification support that works alongside, not instead of, a carrier’s own FMCSA recordkeeping duties.
