Lesson 1.5 — DVIR Documentation
Lesson 1.5 — DVIR Documentation
Why this matters
The Driver Vehicle Inspection Report — the DVIR — is the piece of paper that protects you. The previous four modules taught you how to find problems on the truck. This one teaches you what to do with what you found.
If you find a defect and write it on the DVIR — the legal responsibility shifts to the carrier to fix it. They cannot dispatch you again until repairs are certified. The DVIR is the driver's legal shield.
If you find a defect and don't write it on the DVIR — and an inspector finds it later, or worse, there is a crash — the driver is the one holding the bag. Pencil-whipping the DVIR is the most common way a driver loses their CDL.

What the law actually says
The DVIR rule is 49 CFR 396.11. It is one regulation, three pieces:
End of day — driver writes the report (396.11(a))
Every driver, at the completion of each day's work on each vehicle operated, must prepare a written report covering at least these 11 items:
- 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
The driver signs the report. The driver lists any defect or deficiency that affects the safe operation of the vehicle.
Important update (2014): If you found NO defects during your inspection, you are no longer required by federal law to submit a written DVIR. Most carriers still require a "no defect" report as a company policy, because it documents that the inspection happened.
Carrier fixes the problem and certifies it (396.11(a)(3))
When the driver writes up a defect, the carrier must:
- Repair the defect before the vehicle is dispatched again.
- Have the mechanic or other authorized person certify in writing on the original DVIR that the repair was made — or that the repair was unnecessary.
- That certification is signed.
Until that certification is signed, the truck cannot go back on the road.
Start of next day — next driver reviews and signs (396.13)
Before driving the truck, the next driver must:
- Be satisfied that the vehicle is in safe operating condition.
- Review the most recent DVIR.
- If any defects were reported on the previous DVIR, sign to acknowledge that the repairs were made or were unnecessary.
If a defect was reported and not certified as repaired — the vehicle cannot legally be driven, no matter who is behind the wheel.
The signature chain — three signatures
This is the part most drivers do not understand. A DVIR is a chain of three signatures, and every link must be intact.
1 Driver who found the defect
You. End of the day. You write what you saw and where on the truck you saw it. You sign your name. Date and time.
2 Mechanic or person who fixed it
The shop. They repair the defect — or they decide repair is not needed because the defect does not affect safe operation. Either way, they write a note on the same DVIR and sign their name. This is called the certification of repairs.
3 Next driver who takes the truck
Before you drive a truck someone else drove yesterday: read the previous DVIR. If a defect was reported, look at the mechanic's signature certifying it was fixed. Sign your acknowledgment. If there is no certification — refuse to drive. The truck is not legal.
How to write a useful DVIR entry
Inspectors and judges read DVIRs. Write them clearly. Vague entries protect no one.
| Bad (vague) | Good (specific) |
|---|---|
| "Tire problem" | "Right rear outer trailer tire — sidewall bulge approx 1 inch high, between treads 3 and 4" |
| "Light out" | "Left front trailer clearance lamp not lit during pre-trip" |
| "Brake issue" | "Air loss exceeded 4 PSI in one-minute test, foot brake applied, key on, engine off" |
| "Wheel leak" | "Driver-side rear outer wheel hub — oil streak running from hub face down across lug nuts" |
Specific entries trigger specific repairs. Vague entries get pencil-whipped — the mechanic writes "OK" and nothing gets fixed.
What gets a driver in trouble
Pencil-whipping. Filling out the DVIR in 30 seconds in the cab without actually inspecting the truck. DOT cross-references the DVIR timestamp with your ELD logs. A DVIR completed in 45 seconds is a falsification flag.
Skipping the previous DVIR review. You took a truck without reading the report from yesterday's driver. There was an unrepaired defect listed. You are now driving an unsafe vehicle and YOU are the one cited.
Vague entries. "Brake issue" tells the shop nothing. The shop signs it off without doing anything. The defect remains. You drive again with a known defect.
Not signing. A DVIR without the driver's signature is not a valid report. It is a piece of paper.
Hiding defects. Falsifying a DVIR to hide a defect carries a civil penalty up to $12,695. Failing to repair a reported defect: up to $15,420. Failing to complete a required DVIR: up to $1,584 per day.
What gets you written up
The DVIR-related citation codes that show up on roadside inspections.
| Code | What it means | What the inspector wrote |
|---|---|---|
| 396.11(a)(1) | Required DVIR not prepared | "No DVIR" |
| 396.11(a)(2) | DVIR missing required content | "DVIR incomplete" |
| 396.11(a)(3) | Defects on DVIR not certified as repaired before next dispatch | "Operated with uncorrected defects" |
| 396.13(a) | Driver did not review last DVIR before operating | "Failed to review last DVIR" |
| 396.13(c) | Driver did not sign acknowledgment of repair | "Driver failed to sign DVIR" |
| 390.35 | Falsification of records (DVIR or log) | "False report of record" |
The carrier must retain DVIRs and repair certifications for at least three months from the date the report was prepared. Electronic DVIRs are allowed under 49 CFR 390.32 and the March 2026 FMCSA final rule.
What protects you
- Inspect, then write. Do the actual walk-around. Then write what you found. The order matters — drivers who write first and inspect later get caught by ELD timestamps.
- Write specific entries. Position, part, what you saw. "Right rear trailer tire, sidewall bulge between treads 3 and 4" — not "tire problem."
- Sign it. An unsigned DVIR is not a DVIR.
- Read the previous DVIR before you drive. If defects were listed, check that they are certified as repaired. If they aren't — refuse the truck. You are not legally allowed to drive it.
- Keep yesterday's DVIR with you in the cab. Required by 396.11(b)(4) on the current vehicle. The inspector at the scale will ask for it.
Course summary
You finished Driver Course 1.
You learned to inspect brakes (Module 1.1), tires (Module 1.2), lighting (Module 1.3), and the rest of the equipment (Module 1.4). This final module — DVIR — is how you turn that inspection into the document that protects you.
The truck that gets pulled out of service at the scale is a bad day. The truck that crashes because a defect was not reported is a career. The DVIR is the small piece of paper between the two.
