DVIR Explained: How to Do a Daily Vehicle Inspection Report

The post-trip inspection is one of the simpler compliance requirements in trucking — but also one of the more commonly incomplete ones. Drivers do the walk-around, find nothing wrong, and either skip the paperwork or sign a form that doesn't meet the regulatory standard. That gap is what generates DVIR violations at roadside inspections.

Here's what the DVIR requirement actually is, what you're required to inspect, and how to do it in a way that holds up.

What Is a DVIR?

DVIR stands for Driver Vehicle Inspection Report. It's a written record documenting the condition of your truck and trailer at the end of each operating day — specifically noting any defects or deficiencies that could affect safe operation or out-of-service compliance.

The requirement comes from 49 CFR 396.11 for the driver completing the inspection, and 49 CFR 396.13 for the next driver who reviews the prior report before operating the vehicle. Together, these create a chain of accountability: you document what you found, the carrier certifies any defects were addressed, and the next driver acknowledges the prior report before the vehicle moves again.

For owner-operators running solo, you're both the driver completing the DVIR and the carrier maintaining the record. You write it, certify it, and review your own prior report the next morning.

Who Is Required to Complete a DVIR

DVIR requirements apply to drivers operating commercial motor vehicles subject to FMCSA regulations — primarily interstate CMV operators with a GVWR over 10,001 lbs.

Short-haul exemption: Drivers who qualify for the 150 air-mile short-haul exemption (and are not required to maintain Records of Duty Status) are also exempt from the post-trip DVIR requirement under 49 CFR 396.11(c). If you're exempt from keeping logs because you stay within 150 air-miles and return to your home base within 14 hours, you're also exempt from the written post-trip DVIR.

That said, the pre-trip inspection requirement is separate and applies to all CMV operators. The DVIR exemption covers the written post-trip report, not the inspection habit itself.

If you're required to use an ELD and keep Records of Duty Status, the DVIR requirement applies to you.

What to Inspect

The FMCSA specifies the parts and accessories that must be covered in a driver vehicle inspection. At minimum, your inspection must include:

Braking systems

• Service brakes (tractor and trailer)
• Parking brake
• Air lines and connections (if air-braked)

Steering

• Steering wheel and mechanism (play, looseness, binding)

Lighting devices

• Headlights, taillights, brake lights
• Turn signals, marker lights, clearance lights
• Interior cab lighting as applicable

Tires and wheels

• Tire condition (tread, sidewall damage, visible inflation issues)
• Wheels and rims (no cracked or broken components)
• Lug nuts / wheel fasteners (no missing or loose fasteners)

Coupling devices (if pulling a trailer)

• Fifth wheel (properly locked, no visible damage)
• Pintle hook or other coupling device
• Safety chains or cables

Emergency equipment

• Fire extinguisher (accessible, gauge in operational range)
• Warning triangles, flares, or fusees (three required)
• Spare fuses if the vehicle uses fuses

Other required items

• Horn (operational)
• Windshield wipers (blades condition and operation)
• Rear-view mirrors (properly positioned, unobstructed)
• Driver's seat (secure mounting)

Many ELD apps and fleet management systems include built-in DVIR modules that present each inspection item as a checklist — you tap through the list, mark each item satisfactory or note a defect, and the report generates automatically with your digital signature.

How to Fill Out the Report

Whether you're using a paper form or an ELD-integrated digital DVIR, the report must capture:

1. Date and location of the inspection
2. Vehicle identification — truck unit number or VIN, trailer number if applicable
3. Inspection findings — either "no defects found" or a written description of each defect
4. Driver signature confirming you completed the inspection
5. Carrier certification (for any defects found) — that defects were repaired, or that the vehicle can be operated safely without repair before the next trip

If you find no defects, a "satisfactory condition" notation with your signature completes the record. If you find defects, describe them specifically: "right rear outer drive tire — tread worn to indicator bars" is a usable record. "Tire issue" is not.

The Next-Driver Review

Before operating the vehicle, the next driver must review the prior shift's DVIR and sign it. The signature confirms they reviewed the report — not that defects were necessarily repaired. The carrier certification handles that.

For solo owner-operators, this means reviewing your own prior DVIR before starting each operating day. If you noted a defect the evening before, either confirm it was repaired (and note who repaired it and when), or confirm the vehicle is safe to operate with the defect before going.

Handling Defects

Non-safety defects — cosmetic damage, minor wear items that are within legal limits — still belong on the DVIR. The carrier certifies that repair isn't required before operating. Noting it protects you: if the defect progresses and causes a problem later, the documented inspection record shows you flagged it.

Safety-affecting defects must be repaired before the vehicle is operated again. A failed service brake, a broken fifth-wheel locking mechanism, a leaking fuel line — these are out-of-service conditions. Operating with a known safety defect that's already documented on a DVIR creates serious liability, and the paper trail makes the situation worse, not better.

Out-of-service conditions are specific defect thresholds severe enough to require removing the vehicle from service entirely. The Commercial Vehicle Safety Alliance (CVSA) publishes the North American Standard Out-of-Service Criteria, which lists the exact thresholds for out-of-service violations during roadside inspections. Reviewing it periodically calibrates your eye for how severe a defect needs to be before it crosses from "document it" to "don't move this truck."

Record Retention

Under 49 CFR 396.11, DVIRs must be retained for at least 3 months from the date of the inspection. This applies to both "no defects" reports and defect-noted reports, including the carrier certification on any defects found.

Roadside inspectors and FMCSA compliance reviewers can request DVIR records during audits. Missing records are a violation regardless of whether the inspection physically happened — the regulatory requirement is for the written record.

DVIRs and Your CSA Score

DVIR-related violations appear in the Vehicle Maintenance BASIC of the CSA scoring system. If a roadside inspector finds a vehicle defect that should have been caught in a pre-trip inspection, and your DVIRs don't show a documented inspection history, the combination creates a compliance pattern that CSA tracks over time.

Consistent, complete DVIR records also provide protection when defects are found in an inspection. A documented history showing prior inspections with that defect not present — and the first documentation of it being the current inspection — is meaningful context in a compliance review.

Building DVIRs Into Your Routine

The practical approach is to make the post-trip inspection the last task of every operating day, while you're still next to the truck. Walk the tractor, walk the trailer, complete the report before you go. If your ELD app has a built-in DVIR module, use it — the timestamped digital record satisfies both the driver and carrier recordkeeping requirements automatically.

A common mistake is treating the DVIR as paperwork to do from memory later in the evening. You'll miss things, the timestamps won't match your location, and if you're ever reviewed, the discrepancies create questions.

Truck Command's fleet compliance tools track inspection records, maintenance intervals, and document expiration dates by vehicle — so DVIRs, annual DOT inspections, and preventive maintenance schedules are visible in one place rather than scattered across paper logs and a spreadsheet. Fleet tracking organized by unit keeps each truck's compliance history accessible without hunting through folders.

When a DOT inspection date is approaching or a vehicle's annual inspection is due, you'll get an alert before it becomes a missed deadline. The same visibility applies to driver document renewals — CDL expiration, medical certificates, endorsements — so compliance is proactive rather than reactive.

The DVIR takes five minutes to do correctly. The carriers and owner-operators who get cited for violations usually aren't skipping the walk-around — they're skipping the paperwork or signing a form that doesn't describe defects specifically enough to be compliant. Build the habit, use your ELD's DVIR tool if it has one, describe defects specifically when you find them, and keep the records for at least three months.
