DVIR (Driver Vehicle Inspection Report): Key Facts
A defect missed on a walk-around can become a roadside out-of-service order, a mark against a carrier’s safety score, or the cause of a breakdown. The Driver Vehicle Inspection Report, or DVIR, is documented proof that a commercial vehicle was inspected and that any defect was addressed. Knowing precisely when one is required keeps drivers compliant and increases trucks’ uptime. At CSM Companies, a Kenworth dealer network with more than 45 years in the industry, we see every day how DVIR discipline separates fleets that stay on the road from fleets that sit.
• What it is: a record of a commercial vehicle’s condition, required under FMCSA rules (49 CFR 396.11 and 396.13).
• Who: drivers of most commercial motor vehicles in interstate commerce.
• When: a written post-trip report is required at the end of each driving day when a defect is found, and many carriers require one daily.
• Pre-trip: before each drive, the driver must review the last report and be satisfied the vehicle is in safe operating condition.
• Records: carriers must retain inspection reports and repair certifications for at least three months.
When Is a DVIR Required?
Under 49 CFR 396.11, a driver must prepare a written post-trip report at the end of each day’s work for any commercial motor vehicle they operated. The rule turns on defects: if the driver identifies a defect or deficiency that would affect safe operation or lead to a breakdown, it must be reported. Many carriers go further, requiring a daily post-trip report regardless of whether a defect is found, as a matter of policy.
The pre-trip requirement is separate. Before driving, the driver must review the most recent report to confirm that any noted defect was repaired or judged not to require repair and be satisfied that the vehicle is safe. That review obligation is the part that catches many operations off guard. It is also among the first records a roadside inspector asks to see, which is why every truck repaired in a CSM Companies service bay leaves with its repair certification completed; ensuring compliance at a roadside inspection.
Federal DVIR Requirements and Regulations
The rules sit within the Federal Motor Carrier Safety Regulations, enforced by the FMCSA. Three provisions do most of the work.
49 CFR 396.11: The Post-Trip Report
This is the post-trip requirement. It identifies the components a driver must inspect and establishes that any defect affecting safe operation must be documented at the end of the day.
49 CFR 396.13: The Pre-Trip Review
Before the vehicle moves, the pre-trip review comes down to three steps:
• Confirm safety: the driver must be satisfied the vehicle is in safe operating condition before operating it.
• Review the previous DVIR: the driver must review the last Driver Vehicle Inspection Report if one was generated on the prior trip or if the carrier requires no-defect reports, especially when defects were found and reported.
• Sign and certify: the driver must sign the DVIR to acknowledge the review and confirm that required repairs were certified as performed. This does not apply to defects on a towed unit no longer part of the current combination.
Recordkeeping: Keep Reports Three Months
Carriers must retain each report, the certification that listed defects were repaired and the driver’s pre-trip review certification for at least three months from the date it was prepared. Fall short here and you face fines and safety-score damage. Under the FMCSA penalty schedule, recordkeeping violations can run up to roughly $1,584 per day (as much as about $15,846), and failing to complete a required DVIR runs about $1,270 per day, with far steeper penalties for dispatching a truck with unrepaired defects or operating one placed out of service.
Vehicles and Situations That May Be Exempt
Not every vehicle and trip falls under the same requirement. Drivers of property-carrying trucks generally file a post-trip report only when they find a defect, while passenger-carrying operations face stricter daily requirements. Some single-vehicle owner-operators carry a narrower set of obligations, and intrastate operations follow their state’s rules, which can differ from the federal standard. Because the exceptions are specific and easy to misread, confirm your exact obligation against the regulation or with a compliance advisor rather than assuming.

What Information Must Be Included in a DVIR?
At a minimum, the report identifies the vehicle and the date and records the condition of the components the rule lists. At CSM Companies, every truck serviced goes through a detailed inspection of the following:
• Service brakes, including trailer brake connections
• Parking (hand) brake
• Steering mechanism
• Lighting devices and reflectors
• Tires, wheels and rims
• Horn, windshield wipers and mirrors
• Coupling devices, the fifth wheel and emergency equipment
Common DVIR Compliance Mistakes
The safety managers and service writers across the CSM Companies network see the same pattern: the violations that cause the most trouble are rarely missed inspections. They are skipped pre-trip reviews and vague defect notes. Most problems trace to a handful of avoidable habits:
• Treating it as a formality: signing a report without a genuine inspection is a serious violation.
• Skipping the pre-trip review: drivers must review and accept the last report before driving.
• Failing to certify repairs: a noted defect must be repaired, or judged not safety-related, and certified before the next trip.
• Discarding records early: reports and repair certifications must be kept at least three months.
• Vague defect notes: a one-word entry cannot be repaired or verified; describe the component, its location and the symptom.
“The DVIRs that protect you at roadside are the ones with specific defect notes,” says a CSM Companies service manager. “A note that reads ‘left steer tire, outer shoulder wear’ is repaired and certified the same day. A one-word note usually means a phone call and a parked truck.”
Digital DVIRs vs Paper Inspection Reports
Paper reports remain acceptable, but more fleets are moving to electronic ones. The FMCSA now expressly permits reports to be created, signed, stored and transmitted electronically under 49 CFR 390.32, following a final rule that took effect March 23, 2026. Going digital reduces lost paperwork, timestamps inspections, flags defects to the shop in real time and simplifies the three-month recordkeeping requirement. For a fleet of any size, it is usually the easier route to staying compliant and catching problems before they become downtime. Among the fleets our service departments support, the ones running electronic DVIRs consistently close out defects faster, because the shop sees the write-up before the truck is back in the yard.

FAQs About DVIRs
The questions fleets and drivers ask us most about DVIRs:
Under 49 CFR 396.11, a commercial driver must complete a written post-trip report at the end of each driving day when they find a defect that affects safe operation. Many carriers require one daily regardless. Before driving, 49 CFR 396.13 also requires reviewing the most recent report.
Driver Vehicle Inspection Report. It is a record of a commercial motor vehicle’s condition that documents any defects found during inspection. Federal rules require it for most CMVs in interstate commerce.
Drivers of most commercial motor vehicles in interstate commerce. Requirements are stricter for passenger carriers, which generally need a report every day. Intrastate operations follow their state’s version of the rule, so the exact obligation can vary.
For property-carrying trucks, a written post-trip report is federally required at day’s end only when a defect is found, though many carriers require one daily as policy. Passenger-carrying operations must complete one every day. Either way, the pre-trip review of the last report is required before driving.
A pre-trip inspection is the physical check a driver does before driving, and reviewing the last report is part of it under 49 CFR 396.13. The DVIR itself is the written post-trip report, under 396.11, documenting the vehicle’s condition and any defects at day’s end.
Carriers must keep each report, the certification that listed defects were repaired, and the driver’s pre-trip review certification for at least three months from the date it was prepared. Electronic records are fine as long as they meet FMCSA requirements.
It identifies the vehicle and date and records the condition of key components: service and parking brakes, steering, lights and reflectors, tires, wheels and rims, horn, wipers, mirrors, coupling devices and emergency equipment. The driver notes any defect and signs it, and the carrier certifies repairs before the truck runs again.
Yes. The FMCSA allows these reports to be created, signed, stored, and transmitted electronically under 49 CFR 390.32, and a final rule confirmed this effective March 23, 2026. Electronic records cut lost paperwork, timestamp inspections, and make the three-month requirement much easier to meet.
Skipping or falsifying a required report violates the Federal Motor Carrier Safety Regulations. It can mean fines, a hit to the carrier’s safety score, and, if an unsafe defect goes unreported, an out-of-service order or liability after a crash. Consistent, honest reporting is far cheaper than the alternative.
A report filed when the inspection turns up nothing wrong. Property carriers generally are not federally required to file one when no defect is found, but many fleets require it to document that the inspection happened.
Compliance comes down to a habit: inspect honestly, report clearly, fix what matters, and keep the records. When a defect does turn up, you want it repaired quickly and certified correctly.
