Summary
In short
- 49 CFR 396.11 requires a driver to prepare a written report at the end of each driving day for any defect that would affect safe operation or is likely to cause a breakdown.
- A defect report requires three signatures in sequence: the driver who found it, the person certifying the repair or certifying repair was unnecessary, and the next driver acknowledging the vehicle before operating it.
- Missing signatures, particularly the next-driver acknowledgement, are the most common DVIR audit finding, and a broken chain is a citable violation for both the driver and the carrier.
- Records must be retained for at least three months from the date the report was prepared, covering the report itself, the repair certification and the driver's review certification.
- The regulation names eleven parts and accessories that must be covered, harmonised with the pre-trip inspection requirements at 396.13.
- No-defect reports were removed as a federal requirement for property-carrying vehicles in the 2014 rulemaking, but many carriers retain them because a consistent daily record is evidence that inspections actually happened.
What it is
What it is
What is a DVIR?
A driver vehicle inspection report is the written post-trip report a commercial motor vehicle driver prepares at the end of each driving day under 49 CFR 396.11, covering the vehicle's condition and any defect that would affect safe operation or is likely to cause a breakdown. The carrier must then certify repair before the vehicle runs again.
When is a DVIR required?
A driver must prepare a report at the end of each day's work on any commercial motor vehicle operated, where a defect or deficiency is found or has been reported. Since the 2014 rule change, no-defect DVIRs are no longer federally required for property-carrying vehicles, though many carriers still require them as policy. Passenger-carrying vehicles remain subject to daily reporting.
When to use it
When to use it, and when not to
The DVIR obligation turns on defects, not on days. Understanding which vehicles and which findings trigger a report is what keeps the chain manageable rather than generating paperwork nobody reads.
Use it for
- A driver completes a day's work on a commercial motor vehicle and has found, or been made aware of, a defect affecting safe operation
- Any of the eleven named parts and accessories shows a fault, from service brakes through to emergency equipment
- The vehicle is passenger-carrying, where daily reporting remains required regardless of whether a defect was found
- A defect was reported previously and the next driver must acknowledge the repair before operating the vehicle
- Company policy requires a daily report as evidence that inspections are actually taking place
Not for
- The annual periodic inspection under 396.17, which is a separate qualified-inspector activity with its own record
- Roadside inspection reports issued by enforcement, which carry their own correction and certification requirements
- Hours of service records, which travel with the driver rather than the vehicle
- Preventive maintenance work orders raised on schedule rather than in response to a reported defect
- Non-commercial vehicles and equipment outside the FMCSA definition, which sit under your own fleet policy
Standards
What it is built against
The DVIR sits across two sections that are easy to conflate. 396.11 governs the post-trip report; 396.13 governs what the next driver must do before driving. Auditors trace the join between them.
| Clause | Requirement | Where it lands |
|---|---|---|
| 396.11(a)(1) | Driver prepares a report at the completion of each day's work on each vehicle operated | Header, driver and vehicle |
| 396.11(a)(2) | Report covers the listed parts and accessories | Component inspection |
| 396.11(a)(3) | Driver identifies any defect or deficiency that would affect safety or cause breakdown, and signs | Defects, driver signature |
| 396.11(a)(4) | Retention of the report, repair certification and review certification for three months | Retention |
| 396.11(b) | Carrier repairs any defect likely to affect safe operation before the vehicle is dispatched | Repair |
| 396.11(c) | Certification that defects were repaired, or that repair was unnecessary, before the vehicle is operated | Repair certification |
| 396.13 | Next driver reviews the last report, is satisfied the vehicle is safe, and signs to acknowledge repairs | Next driver review |
| 396.3(b) | Systematic inspection, repair and maintenance records for each vehicle | Whole record |
| NSC Standard 13 | Canadian equivalent, trip inspection reports under provincial adoption | Whole record |
What it does not cover
- Periodic annual inspection under 396.17, which is a separate qualified-inspector activity with its own record.
- Systematic maintenance records under 396.3(b), which track the vehicle over its life rather than over a shift.
- Roadside inspection reports issued by enforcement, which have their own correction and return requirements.
- Hours of service records, which travel with the driver rather than the vehicle.
- Cargo securement checks, which many carriers add to the form but which sit under 393 Subpart I.
The sequence
How the record runs
- 1
Driver completes the post-trip inspection396.11(a)(1)
At the end of the driving day, on each vehicle operated. Record the vehicle identifier, the date, and the driver. Where a defect is found it must be described in terms a mechanic can act on, not as a single word.
- 2
Cover the required components396.11(a)(2)
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, and emergency equipment.
- 3
Driver signs the report396.11(a)(3)
The signature is what makes it a federal record. A driver who signs no defects on a vehicle with a visible fault has falsified that record, which is treated far more seriously than the underlying defect.
- 4
Carrier repairs the defect396.11(b)
Any defect likely to affect safe operation must be corrected before the vehicle is dispatched again. This is the point at which the vehicle should be out of service in the dispatch system, not merely flagged.
- 5
Repair is certified396.11(c)
Someone certifies either that the defect was repaired or that repair was unnecessary for safe operation. An unsigned certification on a completed repair is still a violation, which surprises most operations teams.
- 6
Next driver acknowledges396.13
Before driving, the next driver reviews the last report, satisfies themselves the vehicle is safe, and signs to acknowledge the repair. This is the link auditors check first and the one most often blank.
Audit findings
Common audit findings
DVIR records are among the most examined document categories in a compliance review, because the chain is easy to trace and hard to reconstruct after the fact.
| Finding | Clause | What fixes it |
|---|---|---|
| Next-driver review signature missing on a defect report, so the chain never closed. | 396.13 | Block dispatch until the acknowledgement is captured, rather than relying on the driver to find the previous report. |
| Repair certification missing even though the repair was completed. | 396.11(c) | Certification as a required field on the work order closure, not a separate piece of paper. |
| Records not retained for the full three months, or retained without the certifications. | 396.11(a)(4) | Retain the report, the repair certification and the review certification together as one record for at least 90 days. |
| Defect described too vaguely to act on, such as brakes bad. | 396.11(a)(3) | Structured defect capture by component with a free-text description and a photo. |
| Vehicle dispatched with an open unrepaired safety defect. | 396.11(b) | Out-of-service status applied automatically on a safety-affecting defect and enforced at dispatch. |
| No-defect reports signed on vehicles with visible faults later found at roadside. | 396.11(a)(3) | Compare roadside inspection outcomes against the DVIR for the same vehicle and date, and address the pattern rather than the individual. |
| Required components not all covered by the form in use. | 396.11(a)(2) | Form aligned to the eleven named parts and accessories, with any company additions clearly separate. |
| Trailer inspected on a separate report that is never linked to the tractor record. | 396.11(a)(1) | Report per vehicle unit with the combination recorded, so both records are retrievable together. |
| Electronic records held without the signature chain being reproducible. | 396.11(a)(4) | Export that reproduces all three signatures with timestamps for any vehicle and date range. |
| Reports prepared in advance or in batches at the end of the week. | 396.11(a)(1) | Timestamped capture at the point of inspection, which is the main practical advantage of electronic DVIR. |

By jurisdiction
How the duty differs by jurisdiction
Trip inspection duties exist in every jurisdiction with a commercial fleet regime, but only the US builds the requirement around a signature chain.
49 CFR 396.11 and 396.13
Prescriptive. Named components, three-signature chain, defined retention.
The chain is the artifact. A performed repair with an unsigned certification is still a violation.
NSC Standard 13, adopted provincially
Standard referenced. Trip inspection with a defined schedule of items and defect classification.
Defects are classified as minor or major, with major defects prohibiting operation. The report is valid for 24 hours.
Driver walkaround check, DVSA Guide to Maintaining Roadworthiness
Guidance backed by operator licensing. Daily walkaround check with defect reporting and rectification.
No prescribed federal form, but operator licence undertakings make the record effectively mandatory.
Heavy Vehicle National Law; NHVAS maintenance module
Duty based, with accreditation schemes prescribing daily check and fault recording.
Accredited operators must show a documented fault reporting and rectification loop equivalent to the chain.
Definitions
Definitions and key terms
- DVIR
- Driver vehicle inspection report, the written post-trip report required under 49 CFR 396.11.
- Defect or deficiency
- A condition that would affect the safe operation of the vehicle or is likely to cause a mechanical breakdown. The trigger for a report and for the chain.
- Three-signature chain
- Reporting driver, repair certifier, and next driver acknowledging. All three are required on any report documenting a defect.
- Repair certification
- The signed statement that a reported defect was corrected, or that correction was unnecessary for safe operation.
- Next driver review
- The 396.13 obligation to review the last report and be satisfied the vehicle is safe before driving.
- No-defect report
- A report recording no defects. Not federally required for property-carrying vehicles since the 2014 rule, but commonly retained as policy.
- Out of service
- A vehicle status prohibiting operation until a safety-affecting defect is corrected and certified.
- Periodic inspection
- The separate annual inspection under 396.17, performed by a qualified inspector, distinct from the daily DVIR.
FAQ
Frequently asked questions
Is a DVIR required every day even with no defects?+
Not federally, for property-carrying vehicles. The 2014 rulemaking removed the requirement to submit and retain no-defect reports. Passenger-carrying vehicles remain subject to daily reporting. Many carriers still require daily reports as policy, because a consistent record is the best evidence that inspections actually took place.
How long must DVIRs be kept?+
At least three months from the date the report was prepared. That retention covers all three parts of the record together: the original report, the certification of repairs, and the certification of the next driver's review. Electronic retention is acceptable provided the records are retrievable.
What are the components a DVIR must cover?+
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, and emergency equipment. Carriers commonly add items such as fluid levels and load securement, which should be kept visually distinct from the required set.
What happens if the next driver does not sign?+
The chain is broken and it is a citable violation for both the driver and the carrier, even where the repair was completed correctly. The missing next-driver acknowledgement is the single most common finding in DVIR audits, because it is the link furthest from the person who cared about the defect.
Can DVIRs be electronic?+
Yes. Electronic records and signatures are permitted, and FMCSA has encouraged the transition. The practical advantage is that dispatch can be blocked until each signature exists, so the chain is enforced rather than relied upon, and the ninety-day export is produced in seconds rather than reconstructed from files.
Does the DVIR replace the pre-trip inspection?+
No. They are separate obligations. The DVIR under 396.11 is the post-trip report. The pre-trip duty under 396.13 requires the driver to review the last report, confirm any defect was addressed, and be satisfied the vehicle is safe before driving. Auditors examine the join between the two.
The agents
What the agents do with it
The inspection takes ten minutes. What fails is the ninety days afterwards: the certification nobody signed, the acknowledgement nobody chased, the export nobody can produce.
Captures the report against the vehicle record, applies out-of-service status on a safety-affecting defect, and blocks dispatch until the chain is closed.
Turns a reported defect into a work order and requires the repair certification as part of closing it, so the two cannot separate.
Holds driver qualification and inspection competency, so a report cannot be signed by someone whose training has lapsed.
Produces the ninety-day export by vehicle and date range on request, and holds every write for approval.
