DVIR requirements: what 49 CFR 396.11 actually asks of a carrier

The short version. If you run commercial motor vehicles in interstate commerce, drivers must report any defect they find at the end of the day’s work, the carrier must fix anything that affects safety and certify it before the vehicle runs again, the next driver reviews that report, and the paperwork is kept for three months. Reports may be electronic. The rest of this guide is the detail.

What is a DVIR?

A driver vehicle inspection report is the written record a commercial driver makes about the condition of the vehicle they drove that day. It is required by 49 CFR 396.11, and its job is simple: get defects from the person who found them to the people who fix them, and leave a trail showing the carrier dealt with them before the vehicle went back out.

Who has to prepare a DVIR?

The rule applies to motor carriers operating commercial motor vehicles under the Federal Motor Carrier Safety Regulations. Under 49 CFR 390.5, a vehicle used in interstate commerce is a commercial motor vehicle if any of these is true:

• it has a gross vehicle weight rating or gross combination weight rating — or actual weight — of 10,001 pounds or more;
• it is designed or used to carry more than 8 passengers, including the driver, for compensation;
• it is designed or used to carry more than 15 passengers, including the driver, not for compensation; or
• it carries hazardous materials in a quantity that requires placards.

Section 396.11 itself carves out three exceptions: a private motor carrier of passengers (nonbusiness), a driveaway-towaway operation, and any motor carrier operating only one commercial motor vehicle.

Two practical notes. First, many states adopt the federal rules for intrastate carriers, sometimes with different thresholds, so check your state. Second, plenty of light delivery and service vans sit under the 10,001-pound line, where the federal DVIR rule may not apply at all — yet many of those fleets run a daily inspection anyway, because the operational case is the same.

What a DVIR must cover

The report must cover, at a minimum, these parts and accessories:

The report identifies the vehicle and lists any defect or deficiency the driver found, or that was reported to them, that would affect safe operation or result in a mechanical breakdown. The driver signs it. If the driver operated more than one vehicle that day, each vehicle needs its own report.

The same eleven items appear in 49 CFR 392.7, which says a driver may not drive a commercial motor vehicle unless satisfied that those parts and accessories are in good working order — which is why a good pre-trip covers the same list.

When a driver doesn’t need one

Since December 2014, drivers of property-carrying commercial motor vehicles do not have to prepare a report when no defect or deficiency is found by or reported to them. A 2020 final rule extended the same relief to passenger carriers.

Many carriers still require a DVIR every day as company policy. A daily report proves the inspection happened, keeps the habit alive, and makes a defect report less of an event. Whether you require it is your call; the federal minimum is “report when something is wrong.”

When a driver reports a defect

This is where most of the compliance risk sits. Under 396.11:

1. Repair before it runs. Before requiring or permitting a driver to operate the vehicle, the carrier must repair any listed defect or deficiency likely to affect the safety of operation.
2. Certify the outcome. The carrier, or its agent, must certify on the original report that the defect was repaired or that repair is unnecessary, before the vehicle is operated again.

In practice that means a defect has to reach whoever dispatches the vehicle the same day it is written up, and the vehicle should be treated as unavailable until someone qualified has either fixed it or signed that it does not need fixing.

The next driver’s review

49 CFR 396.13 closes the loop. Before driving, a driver must:

• be satisfied that the vehicle is in safe operating condition;
• review the last driver vehicle inspection report; and
• sign that report — only if defects or deficiencies were noted on it — to acknowledge the review and that there is a certification that the required repairs were performed.

The signature requirement does not apply to defects listed for a towed unit that is no longer part of the vehicle combination.

How long to keep DVIRs

The carrier must keep the original DVIR, the certification of repairs and the certification of the driver’s review for three months from the date the report was prepared. Build your filing around that: a report you cannot find during an audit is not much better than one that was never made.

Electronic DVIRs

Electronic DVIRs are allowed. FMCSA published a final rule in February 2026 that added explicit language to 396.11 and 396.13 saying the reports may be created and maintained in electronic format, in accordance with 49 CFR 390.32, the general rule on electronic documents and signatures. Paper is still permitted; electronic is now spelled out.

Whatever you use, a good electronic DVIR should capture the vehicle and any trailer, the date, the driver, each item’s condition, notes on every defect, the repair certification and the next driver’s review — and make all of it findable for three months or longer.

Pre-trip, post-trip and annual inspections

Read the periodic inspection rule for the details of what an annual must cover and who may perform it.

Common DVIR mistakes

• Pencil-whipping. Every box ticked in thirty seconds without a look at the truck. It produces paper, not inspections.
• Defects with no owner. A defect is written up, nobody is told, and the truck is dispatched before the repair or certification.
• Forgetting the trailer. The report should identify what was pulled, and trailer defects need the same follow-through as tractor defects.
• Certifying without checking. Signing a defect off as repaired because the truck “seemed fine” defeats the point of the certification.
• Paper you can’t find. Three months of reports in a filing box turn every audit question into a search.
