A driver vehicle inspection report (DVIR) is the written report a driver prepares at the end of each day's work listing any defect or deficiency that would affect safe operation or cause a breakdown, with the carrier's certification that the defect was repaired or needed no repair. It is governed by 49 CFR 396.11, with the next driver's review covered in 396.13.
This Heavy Duty Journal guide checks the current rule text, corrects several claims that circulate about DVIRs, explains the 2026 electronic-report change, and shows how to build a program that keeps the repair loop closed. It does not quote fine amounts or audit failure rates that could not be traced to a primary source.
Key Takeaways
- ✓A written report is required when a defect is found. 49 CFR 396.11(a)(2) says drivers are not required to prepare a report if no defect or deficiency is discovered or reported.
- ✓The carrier must repair and certify. Before requiring or permitting a driver to operate, the carrier must repair any safety-affecting defect, and certify on the report that it was repaired or that repair is unnecessary.
- ✓Reports are kept for three months. The DVIR, the repair certification, and the driver's review certification are retained for three months from the date of the report.
- ✓Electronic DVIRs are now written into the rule. A final rule published February 19, 2026 and effective March 23, 2026 added electronic-format language to 396.11 and 396.13.
- ✓Carriers with one CMV are excepted. The exceptions in 396.11(a)(5) cover nonbusiness private passenger carriers, driveaway-towaway operations, and any carrier operating only one commercial motor vehicle.

Driver Vehicle Inspection Report: What Part 396 Requires
Under 49 CFR 396.11(a)(1), every motor carrier must require its drivers to report, and every driver must prepare a report in writing at the completion of each day's work on each vehicle operated. The report must identify the vehicle and list any defect or deficiency discovered by or reported to the driver that would affect safe operation or result in a mechanical breakdown. See the current text on eCFR.
The rule creates a chain: the driver reports, the carrier repairs and certifies, and the next driver reviews before operating. A break anywhere in that chain, such as a repair with no certification or a truck dispatched with an open defect, is the failure auditors look for.
Who Must Prepare a DVIR
The rule applies to motor carriers and their drivers for each commercial motor vehicle operated. Intermodal equipment provided by an intermodal equipment provider is handled separately in 396.11(b), which sets its own report, repair, and retention duties for providers. If a driver operates more than one vehicle in a day, a report is prepared for each vehicle where a defect is found.
Section 396.11(a)(5) excepts three groups: a private motor carrier of passengers on a nonbusiness basis, a driveaway-towaway operation, and any motor carrier operating only one commercial motor vehicle. The exception covers this section only, so a one-truck carrier still has other duties, such as keeping maintenance records. HDJ's maintenance records guide covers those.
The no-defect exception is widely misreported. The current text says drivers are not required to prepare a report if no defect or deficiency is discovered by or reported to the driver, and it makes no property or passenger distinction. Some guides say passenger carriers must file every day. If you run passenger vehicles, confirm that point with FMCSA before relying on the exception.
What the Report Must Cover
The report must cover at least these eleven parts and accessories, and any other defect that would affect safe operation or cause a breakdown must also be listed:
- Service brakes, including trailer brake connections
- Parking brake
- Steering mechanism
- Lighting devices and reflectors
- Tires
- Horn
- Windshield wipers
- Rear vision mirrors
- Coupling devices
- Wheels and rims
- Emergency equipment
Be specific. A notation such as "right rear service brake chamber leaking air at the glad-hand" gives a mechanic something to fix and gives an auditor something to verify. "Brake issue" does neither. The driver signs the report, and on a two-driver operation only one driver needs to sign if both agree on the defects.
The Repair and Review Chain
Under 396.11(a)(3), before requiring or permitting a driver to operate a vehicle, the carrier or its agent must repair any defect listed on the report that is likely to affect the safety of operation. The carrier or its agent must also certify on the report that the defect was repaired or that repair is unnecessary before the vehicle is operated again.
Under 49 CFR 396.13, before driving, a driver must be satisfied that the vehicle is in safe operating condition and must review the last report if one exists. Where defects were listed, the driver signs to acknowledge that the certification shows the repair was made or was unnecessary. See 396.13 on eCFR.
Key Recommendation
Make dispatch check the last DVIR before assigning a unit: an open defect with no repair certification means the truck does not go out.
Keep the certification on the original report, not on a separate work order that never reaches the file. A repair that happened but was not certified on the report looks, to an auditor, like a repair that did not happen.
Retention and Records
A carrier must maintain the DVIR, the certification of repairs, and the certification of the driver's review for three months from the date the written report was prepared. See 49 CFR 396.11(a)(4). Keep the three documents together and retrievable on request.
3 months
How long a carrier must keep the DVIR, the certification of repairs, and the certification of the driver's review, per 49 CFR 396.11(a)(4).
Three months is the minimum, and other records have different periods. Maintenance records, periodic inspection reports, and roadside inspection reports each follow their own rules, and HDJ's annual vehicle inspection requirements guide covers the periodic inspection side. Many carriers keep DVIRs longer, since they can help answer a later question about a vehicle's condition.

The 2026 Electronic DVIR Rule
FMCSA published a final rule on February 19, 2026, effective March 23, 2026 (91 FR 7896, docket FMCSA-2025-0115). It added paragraph 396.11(a)(6), which says the report may be created and maintained in electronic format in accordance with 49 CFR 390.32, and parallel language in 396.11(b)(5) and 396.13(d). See FMCSA's rule page.
FMCSA described the change as a clarification prompted by a public comment from the National Tank Truck Carriers, noting that a DVIR could already be completed electronically. The rule adds the electronic-format paragraphs and does not change what the report must cover or the repair and review duties. Paper reports remain acceptable.
For a fleet, the practical effect is confidence to build a digital workflow. Whatever system you use must still identify the vehicle, preserve the defect description, capture the required signatures and repair certification, and keep the records for three months, in a form consistent with 49 CFR 390.32.
Penalties and Audit Exposure
This article does not repeat a fine table. Civil penalty amounts are set in FMCSA's penalty schedule and are adjusted over time, and the per-violation figures that circulate online were not traceable to a current source. Check the FMCSA civil penalty page for current amounts, and ask counsel how violations would be counted in your case.
The exposure is practical as well as financial. A missing report, a defect left open, or a missing certification shows up in compliance reviews, and equipment defects found at a roadside inspection become part of the carrier's inspection data. HDJ's CSA score guide explains how that data is used, including the status of FMCSA's revised methodology.
Building a Working DVIR Program
Decide on a daily report policy. The rule does not require a report when no defect is found, but many fleets require one every day, with "no defects" marked, because a consistent record shows drivers are inspecting. That is a company choice. HDJ's pre-trip inspection guide covers the walk-around itself.
Close the loop between the shop and dispatch. Route every defect to a work order, record the repair certification on the report, and make dispatch confirm the status before releasing the unit. HDJ's preventive maintenance guide covers how inspection findings feed the PM schedule.
Audit a sample each month. Check that each defect has a certification, that descriptions are specific, and that the report dates and signatures are complete. Compare what drivers report with what roadside inspections find: a pattern of clean reports and repeated roadside defects suggests drivers are not really inspecting, and that is a training and supervision problem.
Electronic systems can help by requiring photos, timestamps, and sign-offs before a unit is cleared, but they only work if the people using them follow the process. HDJ's fleet driver safety program guide covers how inspections fit with training, monitoring, and incident response.
Owner-Operators and Small Fleets
A carrier that operates only one commercial motor vehicle is excepted from 396.11 under paragraph (a)(5), but still has other duties, including pre-trip responsibilities and maintenance records. A carrier with two or more CMVs loses the exception, so a small fleet that grows from one truck to two must start its DVIR process.
Owner-operators leased to a carrier usually work under the carrier's DVIR program. The lease should state who prepares, keeps, and certifies the reports, so there is no gap when a defect is found.
Frequently Asked Questions
Is a DVIR required when no defects are found?
No. 49 CFR 396.11(a)(2) says drivers are not required to prepare a report if no defect or deficiency is discovered by or reported to the driver. Many carriers require daily reports as policy.
How long must a carrier keep DVIRs?
Three months from the date the written report was prepared, covering the report, the certification of repairs, and the certification of the driver's review under 49 CFR 396.11(a)(4).
Can a DVIR be completed electronically?
Yes. FMCSA's final rule effective March 23, 2026 added electronic-format language to 396.11 and 396.13, and reports must be created and maintained in accordance with 49 CFR 390.32.
Who is excepted from the DVIR rule?
Under 396.11(a)(5), nonbusiness private motor carriers of passengers, driveaway-towaway operations, and any carrier operating only one commercial motor vehicle are excepted from that section. The exception does not remove other duties, such as keeping maintenance records.
Who certifies that a defect was repaired?
The motor carrier or its agent certifies on the report that the defect was repaired or that repair was unnecessary before the vehicle is operated again, under 396.11(a)(3).
The Bottom Line
The driver vehicle inspection report works when the chain is complete: a specific driver report, a carrier repair and certification on the original report, a next-driver review, and a dispatch check. The current rule requires a report when a defect is found and three months of retention, and the 2026 change makes electronic reports explicit.
Heavy Duty Journal's guidance at heavydutyjournal.com, from publisher Michael Nielsen and the HDJ editorial team, is to build the shop-to-dispatch loop first and verify any penalty or failure-rate claim against FMCSA before quoting it.
As of October 2026, FMCSA rules and penalty schedules change, so confirm current text before updating your procedures.
