Under 49 CFR §396.11 and §396.13, drivers must prepare and sign a Driver Vehicle Inspection Report at the end of each day’s work when the rules require one, and carriers must repair any listed safety defect before the vehicle goes back on the road. Property-carrying drivers only need to file when they find a defect; passenger-carrying drivers file every day regardless. Carriers keep the original DVIR, the repair certification, and the driver’s review for at least three months.

TL;DR:
Property carriers are only required to file a DVIR when a defect is found, whereas passenger carriers must file daily regardless of defects.
A complete DVIR checklist must include critical parts like brakes, tires, lights, and coupling devices, along with the vehicle’s identity, date, and driver’s signature for audit readiness.
Repairs for safety-related defects must be completed before the vehicle is dispatched again, with certification by an authorized agent and records kept for at least three months.
Electronic DVIRs are permitted if they preserve signatures, timestamps, and links to repair records, with backups stored for a minimum of three months.
On-site, same-day repairs and proper documentation help fleets avoid audit issues and reduce downtime caused by defect-related work.

What Are DVIR Requirements Under 49 CFR §396.11 and §396.13?

Two federal rules govern this process, and fleet managers who understand the split between them avoid most compliance headaches before they start. 49 CFR §396.11 covers the report itself: when a driver must write one, what goes on it, and how the carrier must act on it. 49 CFR §396.13 covers the pre-trip side: a driver has to be satisfied the vehicle is safe to operate and must review the last DVIR when one was required.

Here’s how the obligations break down between the two parties:

Drivers prepare and sign a written report at the end of each day’s work for every vehicle they operated, noting any defect or deficiency that would affect safety or cause a mechanical breakdown.
Carriers must require these reports, review them, and repair anything listed that’s likely to affect safe operation before dispatching the vehicle again, according to FMCSA guidance.
Exceptions exist for private motor carriers of passengers operating non-business vehicles, driveaway-towaway operations, and certain single-vehicle carrier setups.
Intermodal equipment providers face a separate but related reporting and acceptance process when equipment changes hands between carriers.

The rule isn’t a paperwork exercise. FMCSA built it as a closed loop: a driver detects a problem, the carrier fixes it, and someone verifies the fix before the truck moves again. Skip any link in that chain and you’ve got a compliance gap that shows up the moment an auditor pulls files.

What Belongs on a DVIR Checklist?

Federal rules spell out a minimum parts and accessories list, and skipping even one category is a common way fleets fail an audit. Your DVIR checklist should cover:

Service brakes, including trailer brake connections
Parking (hand) brake
Steering mechanism
Lighting devices and reflectors
Tires
Horn
Windshield wipers
Rear-vision mirrors
Coupling devices
Wheels and rims
Emergency equipment

Pro Tip: Auditors treat the DVIR as a first-request document during compliance reviews, so a checklist that mirrors the federal list word-for-word gives you an easy win before they ask a follow-up question, per the Motor Carrier Safety Planner.

Beyond the parts list, every report needs the vehicle’s identity, the date, and the driver’s signature. Drove three trucks in one shift? You file three separate reports, one per vehicle. Pulled a trailer? The towed unit gets its own line or its own report, depending on how your carrier structures the form. Passenger-carrying operations tend to itemize more consistently since they’re filing daily regardless of defects, while property-carrying reports often only exist when something’s actually wrong.

When Do You Need to File a Daily Vehicle Inspection Report?

Timing depends entirely on what you’re hauling, and this is where drivers moving between passenger and freight assignments get tripped up. Passenger-carrying commercial motor vehicles require a report after each day or trip, defect or no defect. Property-carrying CMVs only require a report when the driver actually discovers or is told about a defect or deficiency.

A few operational scenarios add wrinkles:

Two-driver operations: a single signature is acceptable if both drivers agree on the reported condition, though a written acknowledgment from the second driver in the vehicle log helps head off disputes.
Multi-vehicle days: each vehicle operated needs its own report. There’s no combining trucks onto one form just because the driver’s shift covered all of them.
Intermodal equipment: the provider has a separate reporting and acceptance obligation when a piece of equipment moves from one carrier’s control to another’s, distinct from the standard driver DVIR process.

The 2014 rule change removed the federal requirement for no-defect DVIRs on property-carrying vehicles, but many carriers still ask drivers to file them anyway. It keeps an unbroken paper trail and reinforces a habit of actually inspecting the truck instead of skipping the walkaround on a day nothing looks wrong.

Corrective Action, Repair Certification, and How Long You Keep the Records

A defect on paper doesn’t fix itself, and the carrier’s next move is where most compliance failures actually happen. Once a driver lists a safety-affecting defect, the carrier has to repair it before the vehicle operates again. That’s not optional language in the regulation. FMCSA guidance is direct: anything likely to affect safe operation gets fixed first, dispatched second.

Someone has to certify that repair on the original DVIR, and that person doesn’t need to be a certified mechanic. FMCSA’s own guidance says the certifier needs to be an authorized agent of the carrier who’s competent to confirm the repair was actually done, whether that’s a shop foreman, a fleet maintenance lead, or a mobile technician who did the work directly.

Retention rules are specific:

Keep the original DVIR, the repair certification, and the driver’s review certification for a federally mandated retention period from the date the report was prepared, as required under 49 CFR §396.11.
Periodic (annual) inspection records get a longer shelf life, generally over a year.

Pro Tip: Store the DVIR retention clock separately from your annual inspection records in whatever system you use. Mixing the two timelines is one of the more common filing mistakes we see when carriers get audited.

Electronic DVIRs and Keeping Records Audit-Ready

Paper isn’t required. Electronic DVIRs are fully permitted, provided they meet the same signature and retention standards as paper ones under 49 CFR §396.13, which cross-references the electronic recordkeeping standards in 49 CFR 390.32. FMCSA expects carriers to preserve either the original electronic record or a faithful reproduction, complete with signatures, certifier identity, and timestamps.

Three practices keep an electronic system defensible when an auditor comes calling:

Preserve the original electronic record, not a summary or export, and make sure certifier identity and timestamps travel with it.
Link each DVIR ID to its corresponding work order and invoice, which makes repair certification far harder to dispute during a review.
Store backup copies for at least three months, matching the federal retention floor for DVIRs and their certifications.

The audit findings that trip up fleets most often: a missing certifier name or title, an incomplete parts list that skips a required category, and failing to generate a separate report for each vehicle on a multi-vehicle day. All three are easy to prevent and expensive to explain after the fact.

Practical Compliance Tips From Premier Fleet Repair

A DVIR is only as useful as what happens after it’s filed. Premier Fleet Repair treats every defect listed on a report as a trigger for same-day, on-site service, logging the technician’s name, the job number, and the timestamp directly against that DVIR. That single habit closes the loop auditors care about most: detection, repair, verification, all traceable to one document.

Standardize a short list of authorized certifiers and record their title on every report. It cuts down on the follow-up questions auditors ask when a signature doesn’t match a name they recognize. Where possible, tie your DVIR IDs to your maintenance software so a complete audit packet, the DVIR, the certification, and the invoice, exports as one bundle instead of three separate hunts through different files. That kind of integration is exactly what a multi-driver accountability system is built to support.

Our Take: DVIRs Are a Safety Loop, Not a Signature Line

Most compliance guides treat the DVIR as a form to fill out correctly. That’s the wrong frame. The regulation exists to force three things to happen in sequence: a driver notices a problem, the carrier fixes it, and someone verifies the fix in writing before the truck rolls again. Get any one of those steps wrong and the paperwork won’t save you in an audit.

Where conventional advice falls short is treating certifier identity as an afterthought. Fleets spend enormous effort perfecting their parts checklist and almost none confirming that the name signing off on repairs is documented with a title and authority level. That gap is what generates the most avoidable audit questions, and it’s fixable with a five-minute policy change: name your certifiers, record their titles, and never let a repair get signed off by someone whose authority isn’t written down anywhere.

If you prioritize one thing this quarter, make it that. The parts list matters, but everyone gets that part right. Certifier accountability is where fleets actually lose points.

FAQ

Who Is Required to Fill Out a DVIR?

Any driver operating a commercial motor vehicle subject to Federal Motor Carrier Safety Regulations must prepare a DVIR under the conditions set by 49 CFR §396.11: daily for passenger-carrying CMVs, and only when a defect is found for property-carrying CMVs.

What Is Not a DVIR Requirement?

A no-defect report on a property-carrying CMV is not federally required since the 2014 rule change, though many carriers still request one internally to maintain a consistent inspection habit and paper trail.

When Should a Driver Complete a DVIR?

Passenger-carrying drivers complete one at the end of each day or trip regardless of vehicle condition. Property-carrying drivers complete one only when they discover or are informed of a defect that could affect safety or cause a breakdown.

How Do I Know if I Am Subject to FMCSR?

You’re generally subject to the Federal Motor Carrier Safety Regulations if you operate a commercial motor vehicle in interstate commerce that meets weight, passenger, or hazardous materials thresholds; check your specific vehicle and operation against the definitions in 49 CFR Part 390 or consult your carrier’s compliance officer.

How Long Must Carriers Keep DVIR Records?

Carriers must retain the original DVIR, the repair certification, and the driver’s review certification for at least three months from the date the report was prepared.
