DVIR Requirements Explained: FMCSA 49 CFR 396.11 in Plain English

A driver vehicle inspection report — a DVIR — is one of the most routine documents in a fleet, and one of the most cited during audits. The rule behind it, 49 CFR 396.11, is short, but it is easy to misread. This guide walks through what it actually asks for, where fleets usually slip, and how to turn it into a two-minute habit for drivers.

This is a plain-English summary, not legal advice. Always check the current text of the regulation (linked in the sources below) and any state rules that apply to your operation.

What a DVIR is

A DVIR is the written report a driver completes about the condition of a commercial motor vehicle. It names the vehicle, lists any defect the driver found or was told about that would affect safe operation or could cause a breakdown, and carries the driver’s signature. Its job is simple: make sure defects are seen, fixed and signed off before the vehicle goes back on the road.

Who must complete one

Section 396.11 applies to motor carriers subject to the Federal Motor Carrier Safety Regulations — in practice, fleets running commercial motor vehicles in interstate commerce. The section itself excludes three cases:

• private motor carriers of passengers (non-business),
• driveaway-towaway operations, and
• any motor carrier operating only one commercial motor vehicle.

Intrastate-only fleets are usually covered by their state’s version of the rules, which often mirrors the federal one.

The 11 items a DVIR must cover

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

Fleets can — and usually should — add their own items on top, such as fluid levels, body damage or cargo securement. The 11 are the floor, not the ceiling.

Do you still need a no-defect DVIR?

This is the most common question. The current rule says drivers are not required to prepare a report if no defect or deficiency is discovered by or reported to them. That relief arrived in 2014 for property-carrying vehicles and was extended to passenger-carrying vehicles in 2020.

What did not change: the driver still has to inspect the vehicle, and any defect still has to be written up. Many fleets keep collecting no-defect reports anyway, because a clean record is the easiest way to show an auditor — or a lawyer after a crash — that inspections really happened.

Defects, repairs and certification

When a DVIR lists a defect, the carrier (or its agent) must, before the vehicle is driven again:

1. repair any defect that would be likely to affect safe operation, and
2. certify on the original report that the defect was repaired, or that a repair was unnecessary, with a signature.

In practice this is where paper DVIRs break down: the report sits in a cab or a tray, the shop fixes the brake light but nobody signs the certification, and the next driver has no way of knowing. A clear open defects list with a “don’t dispatch” status solves most of it.

The next driver’s review (396.13)

Before driving, section 396.13 requires the driver to:

• be satisfied that the vehicle is in safe operating condition,
• review the last DVIR, and
• sign it to acknowledge the review, if defects were noted and a repair certification was made — the signature isn’t required when no defects were reported.

How long to keep DVIRs

The carrier must keep the original DVIR, the certification of repairs and the next driver’s review for three months from the date the report was prepared. Keep them together: during a review, an auditor will want to see the whole chain for a defect — written up, fixed, certified, acknowledged.

Paper vs electronic DVIRs

FMCSA allows required records and signatures to be kept electronically, so a DVIR app is fine as long as the report contains everything the rule requires and you can produce it on request. What an app adds over paper:

• photos of each defect, time-stamped, instead of “light out”;
• an automatic hand-off to the shop and a signed repair certification;
• the next driver sees open defects before the trip and signs on the phone;
• a searchable DOT file instead of a box of carbon copies;
• offline capture, so a dead zone in the yard doesn’t stop the inspection.

WW Inspectionsdoes exactly this for fleets: pre-trip and post-trip DVIRs with photos, certified repairs, the next driver’s review and a DOT file — on iPhone, iPad and Android.

A practical daily routine

1. Before the trip: open the vehicle, review the last report, sign if there was a certified defect, walk around.
2. During the day: write up anything new as soon as it shows up — don’t wait for the end of the shift.
3. End of day: complete the post-trip report covering the 11 items, with photos of any defect.
4. Shop: fix or assess every open defect, certify it, and only then release the vehicle.
5. Office: review open defects daily and keep the full chain for three months.
