If you've spent time building out your driver qualification files, you've probably triple-checked MVR reports, drug test results, and employment history forms. But there's one document that fleets — especially small operations — consistently miss: the road test certificate mandated by 49 CFR Part 391.31.

This isn't a technicality. It's a hard federal requirement, and FMCSA compliance officers know exactly where to look for it. Let's break down what it is, what it must contain, and how to make sure your fleet never gets caught without one.

What Is the Road Test Certificate Under 49 CFR 391.31?

The road test certificate is a signed document proving that a driver demonstrated the ability to operate a commercial motor vehicle safely before being placed on duty. Under 49 CFR 391.31, every motor carrier must administer this test and retain the certificate in the driver's qualification file.

The regulation requires a motor carrier — or a person acting on the carrier's behalf — to administer a road test to every driver before that driver operates a CMV. The test must be followed by a signed certificate from the examiner and a copy retained in the DQ file. The certificate must state the type of vehicle operated during the test, since qualification is vehicle-specific.

Here's what the certificate must include:

• Driver's name and signature
• Motor carrier's name and address
• Date of the test
• Name of the examiner who administered the test
• Examiner's signature
• Type of commercial motor vehicle used in the test
• A statement of whether the driver passed or failed

The examiner's score sheet — the document used during the actual driving evaluation — must also be preserved in the DQ file alongside the certificate.

What Happens If a Road Test Certificate Is Missing From a DQ File?

A missing road test certificate is a recordkeeping violation under FMCSA regulations. Fines for general FMCSA violations reach $19,246 per violation, and each driver file with a missing document can count as a separate violation during an audit.

During a compliance review, investigators are trained to pull DQ files at random and check for completeness against the requirements in 49 CFR 391.51, which governs what must be retained. A missing road test certificate appears on an audit as a clear, unambiguous failure — there's no explanation that resolves it other than producing the document. Carriers with multiple drivers missing certificates can face compounding fines that add up fast for a small fleet operating on tight margins.

Beyond the fine, a pattern of incomplete DQ files can trigger a conditional or unsatisfactory safety rating, which affects your ability to haul freight, maintain insurance rates, and retain shipper contracts.

Can a CDL Substitute for the Road Test Requirement?

Yes — but the substitution must be properly documented. Under 49 CFR 391.33, a motor carrier may accept a valid commercial driver's license as proof of road test completion, but only if the CDL covers the type of vehicle the driver will operate for your fleet.

This is where many fleets make mistakes. The CDL substitution only works when the license class and endorsements match the actual vehicle. A Class B CDL does not substitute for a road test on a combination vehicle requiring a Class A. If you're onboarding a driver with a Class A CDL who will pull a tanker, you also need to verify the tanker endorsement is present. When using the CDL substitution, your DQ file must contain a copy of the driver's valid CDL as the documented substitute — a verbal confirmation or a note in the file is not sufficient.

How Long Must the Road Test Certificate Be Retained?

Under 49 CFR 391.51(b), the road test certificate must be kept in the DQ file for the duration of the driver's employment plus three years after the driver leaves. Failing to retain the document within that window is itself a recordkeeping violation.

Recordkeeping violations carry fines up to $1,584 per day with a maximum of $15,846 per investigation — separate from the per-violation penalty for the missing document itself. For a small fleet, losing paper DQ files in a move, a flood, or a staff transition isn't an excuse that holds up in a compliance review. This is precisely why digital document management matters.

What Is New in 2026 for Road Test and DQ File Requirements?

In 2026, there are no new statutory changes to the road test certificate requirement itself under 49 CFR 391.31. However, FMCSA's increased focus on Entry-Level Driver Training (ELDT) compliance and the integration of the Training Provider Registry (TPR) has made DQ file completeness a higher priority during compliance reviews.

Investigators now cross-reference DQ files against TPR records for drivers who obtained CDLs after February 7, 2022. If your driver's CDL was issued post-ELDT mandate and you're relying on the CDL substitution under 391.33, the system flags whether that license reflects completed ELDT. Gaps in either the road test certificate or the ELDT documentation create compounding audit exposure. For more on ELDT requirements and how they interact with your hiring process, see our full breakdown at ELDT requirements for small trucking fleets.

Additionally, FMCSA's DataQ system continues to make violation histories more accessible to shippers and brokers, increasing the business consequences of compliance failures beyond the fine itself.

Does the Road Test Requirement Apply to Owner-Operators and Small Fleets?

Yes, without exception. 49 CFR 391.31 applies to every motor carrier subject to the Federal Motor Carrier Safety Regulations — including single-truck operations, owner-operators who also employ drivers, and fleets with fewer than five vehicles.

There is no small fleet exemption in Part 391. The only relevant threshold is whether the vehicle is a CMV as defined under 49 CFR 390.5 — generally a vehicle with a GVWR over 10,001 pounds used in interstate commerce, or a vehicle hauling hazardous materials in quantities requiring placards. If your vehicles meet that definition, every driver needs a road test certificate or a properly documented CDL substitution in their DQ file before their first dispatch.

How Do You Administer a Road Test That Meets 49 CFR 391.31?

The road test must be conducted over a public road or a simulated environment that represents real operating conditions. It must cover the specific type of vehicle the driver will operate, and the examiner must complete a written score sheet covering all evaluated maneuvers.

Here are the core components the road test must cover:

1. Pre-trip vehicle inspection procedure
2. Coupling and uncoupling of combination vehicles (if applicable)
3. Placing the vehicle in operation and use of controls
4. Use of mirrors, signals, and lane use
5. Turning, backing, and parking
6. Braking and emergency situations
7. Shifting and use of retarder (if applicable)

After the test, both the driver and the examiner sign the certificate. The examiner keeps a copy; the motor carrier retains the original certificate and the completed score sheet in the DQ file.

What Does a Complete DQ File Look Like in 2026?

The road test certificate is one of many required documents. A complete DQ file under 49 CFR 391.51 includes the application, MVR, medical certificate, employment verifications, annual review, and the road test certificate or CDL substitution copy.

For a full document-by-document checklist of everything required in a DQ file this year, review our detailed guide at driver qualification file checklist for 2026. Missing any single element during a compliance review creates audit exposure — but the road test certificate is one of the most frequently missing and easiest to prevent.

Frequently Asked Questions

Q: Is the road test certificate required for drivers who already have a CDL?

Not necessarily. Under 49 CFR 391.33, a valid CDL of the appropriate class and endorsement can substitute for the road test. However, you must retain a copy of that CDL in the DQ file as the documented substitution. You cannot simply skip the file entry — the substitution must be recorded.

Q: Who is allowed to administer the road test under 49 CFR 391.31?

The motor carrier or a person designated by the carrier may administer the test. That person does not need a special certification, but they must be qualified to evaluate the driver's performance on the specific type of vehicle used in the test. The examiner must sign both the score sheet and the resulting certificate.

Q: Does the road test have to be on the same type of vehicle the driver will operate daily?

Yes. The certificate must identify the type of vehicle used during the test, and the driver is only qualified under 49 CFR 391.31 for that vehicle type. A driver tested on a straight truck requires a separate road test — or appropriate CDL substitution — before operating a combination vehicle for your fleet.

Q: What is the penalty for operating a CMV driver without a road test certificate on file?

FMCSA general violation fines reach $19,246 per violation. Each driver file missing the certificate can be cited as a separate violation. Recordkeeping violations for failing to retain the document can add up to $1,584 per day, capped at $15,846 per investigation period.

Q: Can a road test be waived for a driver who passed a state CDL skills test?

Yes. Under 49 CFR 391.33(a)(2), a motor carrier may accept a copy of the results of a skills test administered by a state or third-party tester. The results must be for a vehicle of the same type the driver will operate. The copy of those results serves as the substitute and must be filed in the DQ file.

Q: How does FMCSA verify road test compliance during an audit?

During a compliance review, investigators request DQ files for a sample of drivers — active and recently terminated. They check each file against the 49 CFR 391.51 retention checklist. A missing road test certificate or CDL substitution copy is immediately documentable as a violation. There is no corrective action available during the audit; the document must already exist.
