The Definition of Driver Vehicle Inspection Report (DVIR)

Definition of Driver Vehicle Inspection Report (DVIR)

A Driver Vehicle Inspection Report (DVIR) is a record, on paper or in electronic form, that a commercial driver completes to document the condition of a vehicle and any defects that could affect safe operation.

The DVIR is the link between the driver who finds a problem and the mechanic who fixes it. When a driver notes worn brakes, a cracked mirror or a leaking tire, the report triggers a repair and a sign-off before the vehicle goes back on the road. Without that loop, defects get missed, forgotten or passed on to the next driver.

DVIRs are required for many commercial motor vehicles in interstate commerce, including trucks, tractors, trailers and buses. Fleets in trucking, construction, utilities, waste hauling, oil and gas, and passenger transport use them. Many companies also apply the same process to light vehicles and mobile equipment as part of a wider pre-use inspection program.

How a DVIR Works

Items Covered

Under 49 CFR 396.11, the report must cover at least these parts and accessories:

• Brakes: Service brakes, including trailer brake connections, and the parking brake.
• Steering mechanism: Play, damage or abnormal operation.
• Lighting devices and reflectors: Headlights, tail lights, turn signals, brake lights and reflectors.
• Tires, wheels and rims: Tread, inflation, cuts, cracks and loose or missing lug nuts.
• Horn and windshield wipers: Working condition.
• Rear vision mirrors: Present, secure and undamaged.
• Coupling devices: Fifth wheel, pintle hook and safety chains.
• Emergency equipment: Fire extinguisher, warning triangles and other required items.

The Inspection Cycle

• Before driving: The driver checks that the vehicle is in safe operating condition and reviews the last DVIR.
• End of day: The driver prepares a report on each vehicle operated that day and notes any defect found.
• Repair and certification: The motor carrier repairs any defect that affects safe operation and certifies the repair, or certifies that repair was not needed.
• Driver acknowledgment: The next driver reviews the report and signs it if defects were noted and certified as repaired.

Paper and Electronic DVIRs

• Paper forms: Carbon-copy books are still common. They are simple but easy to lose or fill out poorly.
• Electronic DVIRs: Electronic reports are permitted. Apps and telematics tools can add photos, time stamps and automatic alerts to maintenance staff.

Regulations and Standards

49 CFR 396.11: Driver Vehicle Inspection Reports

This section requires drivers to prepare a written report at the end of each day's work on each vehicle operated. Since a 2014 FMCSA rule, drivers of property-carrying commercial motor vehicles do not need to submit a DVIR when no defect is found. Requirements for passenger carriers differ, so check the current rules if you operate buses or motorcoaches. When defects are reported, the motor carrier must repair any defect that would affect safe operation before the vehicle is dispatched again, and must certify the repair or certify that repair was unnecessary. The carrier must keep the original DVIR and the certification of repair for three months from the date the report was prepared. Intermodal equipment, such as chassis provided by an intermodal equipment provider, has its own reporting rules in 396.11(b).

49 CFR 396.13: Driver Inspection

Before driving, the driver must be satisfied that the vehicle is in safe operating condition. The driver must review the last DVIR and sign it if defects were noted and certified as repaired. This makes the driver the final check before the vehicle moves.

Related Maintenance Rules

The DVIR works alongside the carrier's broader inspection, repair and maintenance duties in Part 396. A strong preventive maintenance schedule catches wear before it shows up as a defect on a driver report.

Good Practices for DVIRs

• Make inspections real, not a checkbox: Train drivers on what each item looks like when it is failing, and give them time in the schedule to inspect properly.
• Report every defect: Encourage drivers to note small problems. A minor air leak today can be a brake failure next week.
• Close the loop fast: Route reported defects straight to maintenance and track them until repaired and certified. Treat unrepaired items as defective equipment and keep the vehicle out of service.
• Go electronic: Electronic DVIRs with photos reduce lost paperwork and illegible notes. A tool such as SafetyIQ asset and equipment inspection software can assign repairs and keep records organized.
• Keep records organized: Store reports and repair certifications so they can be found for at least three months, or longer if company policy requires.
• Review trends: Look for vehicles or parts that show up on reports again and again. Repeat defects point to maintenance or specification problems.

Example of Driver Vehicle Inspection Report (DVIR)

A regional ready-mix supplier used paper DVIR books in each truck. A driver noted a slow air leak on a Friday report, but the page stayed in the truck over the weekend. On Monday, a different driver took the truck without reviewing the last report. The leak worsened during the day and the low-air warning came on while the truck was loaded on a downhill grade. The driver stopped safely on the shoulder.

After investigating, the company moved to electronic DVIRs. Any reported defect now sends an alert to the shop and blocks the truck from dispatch until a mechanic certifies the repair. Drivers must open and acknowledge the last report before starting their pre-trip check. The company also added DVIR review to its workplace inspection audits. Open defects older than one day dropped to near zero.

Frequently Asked Questions: Driver Vehicle Inspection Report (DVIR)

Is a DVIR required if there are no defects?

For property-carrying commercial motor vehicles, no. Since a 2014 FMCSA rule, those drivers do not need to submit a DVIR when no defect is found. Passenger carriers have different requirements, so check the current rules.

How long must DVIRs be kept?

The motor carrier must keep the original DVIR and the certification of repair for three months from the date the report was prepared. Some companies keep them longer for maintenance history.

What must a driver do before driving a vehicle?

Under 49 CFR 396.13, the driver must be satisfied that the vehicle is in safe operating condition and must review the last DVIR. If defects were noted and certified as repaired, the driver signs the report to acknowledge it.

Are electronic DVIRs allowed?

Yes. Electronic DVIRs are permitted. They must capture the same information as a paper report, including the defects found, the repair certification and the required signatures.
