The short answer: a DVIR is a report, not an inspection. Under 49 CFR 396.11(a)(1) the driver prepares it in writing at the completion of each day's work on each vehicle operated, and under 396.11(a)(2)(i) it must identify the vehicle and list any defect or deficiency discovered by or reported to the driver that would affect the safety of operation or result in a mechanical breakdown. The same paragraph ends with the sentence that changed the whole workflow: drivers are not required to prepare a report if no defect or deficiency is discovered by or reported to the driver. No defects, no paper.
Then the signatures. The driver signs the report he prepared, 396.11(a)(2)(ii). The carrier or its agent repairs the defect and certifies on that same report that it was repaired or that repair is unnecessary before the vehicle is operated again, 396.11(a)(3). The next driver signs under 396.13(c) to acknowledge that he reviewed the report and that the certification of repairs is there. All three pieces are kept three months from the date the report was prepared, 396.11(a)(4). What follows is a walk-through of the rules, not individual advice. Everything below is sourced to the rule text at 49 CFR 396.11, 396.13, 396.3, 392.7 and to FMCSA's own published guidance on Section 396.11.
Three letters cause more confusion than any other paperwork in a small fleet, because the acronym reads as an inspection. It is not. The regulation is titled Driver vehicle inspection report(s), and the operative word is the last one.
FMCSA answered this directly. Asked whether 396.11, which requires a written report on each vehicle operated at the completion of each day's work, requires a post-trip inspection of the kind described in 396.15, the agency's published guidance answers: no. It then adds the part that matters: the written report must include all defects in the parts and accessories listed in 396.11(a)(1) that were discovered by or reported to the driver during that day.
Read that twice, because it reframes the whole job:
No. The current text of 396.11(a)(2)(i) ends with one flat sentence: "Drivers are not required to prepare a report if no defect or deficiency is discovered by or reported to the driver." That sentence is in the rule itself, and it works the same way for everyone the section covers. There is no property-carrying versus passenger-carrying split anywhere in 396.11 today.
This is where old habits and old blank forms go wrong, so keep the chronology in your head. Filing a report every single day regardless of whether anything was wrong was the norm for decades, and the sentence above reached its present unqualified form through two FMCSA rules, both credited in the amendment list of Section 396.11 on eCFR. The first, published December 18, 2014 at 79 FR 75449, dropped the daily no-defect report for property carriers. The second, Passenger Carrier No-Defect Driver Vehicle Inspection Reports, published August 18, 2020 at 85 FR 50787 with the amendment credited at 85 FR 50793 (docket FMCSA-2019-0075) and effective September 17, 2020, removed the separate sentence that had obliged the driver of a passenger-carrying CMV to file even with no defects.
One caution about sourcing, because it trips up people who check their homework. FMCSA's guidance page answering Question 1 to 396.11 still carries the repealed passenger sentence; it was never updated after 2020. The rule text on eCFR governs, the guidance page does not. Anyone quoting you "a DVIR every day, defects or not" is quoting paperwork retired in 2014 for freight and in 2020 for buses.
Here is the distinction that half the phone calls to our office are really about. These three are not versions of one another. Different section, different moment, different person, different retention period, different violation code if you miss it.
The pre-trip inspection is a duty of the driver, before driving, under 392.7 and 396.13. It produces no mandatory standalone document of its own under Part 396. What it produces is a decision: drive or do not drive. Under 396.13 the driver must (a) be satisfied the vehicle is in safe operating condition, (b) review the last DVIR if one was required by 396.11(a)(2)(i), and (c) sign that report to acknowledge the review and that the certification of repairs is present.
The DVIR is a report by the driver at the end of the day, under 396.11, listing defects. It exists only when there are defects to list.
The annual, or periodic, inspection is an entirely separate machine. Under 396.17(c) a motor carrier must not use a commercial motor vehicle unless each component identified in appendix A to Part 396 has passed an inspection at least once during the preceding 12 months and documentation of that inspection is on the vehicle. Under 396.17(a) the term commercial motor vehicle includes each vehicle in a combination: for a tractor, semitrailer and full trailer combination, the tractor, the semitrailer and the full trailer with its converter dolly must each be inspected. It is performed by a qualified inspector under 396.19, the report content is set by 396.21(a), and the documentation on the vehicle may be the report itself or a sticker or decal carrying the inspection date, the name and address of where the report is kept, information identifying the vehicle, and a certification that it passed. If the unit passed a State, Canadian or Mexican periodic inspection meeting the appendix A minimum standards, 396.17(f) counts it as the annual inspection for 12 months running from the last day of the month in which it was performed, which is usually a few extra days rather than a few extra weeks.
| Document | When it happens | Who does it | How long it is kept |
|---|---|---|---|
| Pre-trip inspection 49 CFR 392.7, 396.13(a) | Before driving, every time | The driver | No standalone record required by Part 396. The proof is the signed review on the last DVIR |
| Review and signature on the last DVIR 49 CFR 396.13(b), (c) | Before driving, when a DVIR was required | The next driver | 3 months from the date the report was prepared, together with the DVIR, per 396.11(a)(4) |
| DVIR 49 CFR 396.11(a)(1), (a)(2) | At the completion of each day's work, only if a defect was discovered or reported | The driver who operated the vehicle. One report per vehicle operated that day | 3 months from the date the written report was prepared, per 396.11(a)(4) |
| Certification of repairs on the DVIR 49 CFR 396.11(a)(3)(ii) | Before the vehicle is operated again | The motor carrier or its agent | 3 months, kept with the DVIR |
| Intermodal equipment defect report 49 CFR 396.11(b) | At the time the equipment is returned to the provider or its agent | Driver or motor carrier reports; the intermodal equipment provider receives and repairs | 3 months from submission, held by the equipment provider, per 396.11(b)(4) |
| Roadside inspection report (DVER) 49 CFR 396.9 | After a roadside inspection. Corrections certified within 15 days | Officer issues; driver delivers it to the carrier; carrier certifies corrections | 12 months from the date of the inspection, per 396.9(d)(3)(ii) |
| Annual (periodic) inspection report 49 CFR 396.17, 396.21 | At least once in the preceding 12 months, each unit of a combination separately | A qualified inspector under 396.19, in house or a commercial garage acting as agent | 14 months from the date of the inspection report, where the vehicle is housed or maintained, per 396.21(b)(1) |
| Proof of periodic inspection carried on the vehicle 49 CFR 396.17(c) | Continuously, while the vehicle is in use | The carrier puts the report or the sticker or decal on the vehicle | Current one must be on the vehicle at all times it is used |
| Systematic maintenance records 49 CFR 396.3(b) | Ongoing, for each vehicle controlled 30 consecutive days, other than a private motor carrier of passengers (nonbusiness): carve-out added by 91 FR 45662, July 21, 2026 | The motor carrier | 1 year, and 6 months after the vehicle leaves the carrier's control, per 396.3(c) |
If you print one thing from this article, print that table and tape it inside the file cabinet. Three months, twelve months, fourteen months and one year plus six are four different numbers, and mixing them is the single most common reason a carrier hands an investigator an incomplete file while genuinely believing it is complete. The annual inspection side of this, including who counts as a qualified inspector and what has to be on the vehicle, is worked through in annual inspection and maintenance records.
396.11(a)(1) sets the floor: a written report at the completion of each day's work on each vehicle operated, except for intermodal equipment tendered by an intermodal equipment provider, which runs on 396.11(b) instead. The report shall cover at least these eleven parts and accessories:
Those eleven items are worth memorising for a second reason: 392.7(a) lists exactly the same eleven as the parts the driver must be satisfied are in good working order before driving. The pre-trip duty and the report scope are deliberately aligned. If you build one checklist covering those items, it serves both sections.
Content requirements from 396.11(a)(2), in order:
Two practical permissions from FMCSA guidance that save real time. First, a multi-day DVIR form is acceptable under 396.11 and 396.13, provided all information and certifications required by both sections appear on the report. Second, the person who certifies the repair does not have to be a mechanic: FMCSA guidance states that 396.11 establishes no minimum qualifications for the motor carrier official or agent who certifies that defects were corrected or that correction was unnecessary. Part 396 sets qualification requirements only for the individual performing the periodic inspection under 396.19 and for employees responsible for brake-related inspection, repair or maintenance tasks under 396.25.
This is the question that decides whether your file is a compliance record or a stack of paper. The sequence is fixed by the regulation and it runs in one direction.
| Step | Who signs | What the signature means | Section |
|---|---|---|---|
| 1 | The driver who operated the vehicle | This is my report of the defects discovered by or reported to me during this day's work | 396.11(a)(2)(ii) |
| 2 | The motor carrier or its agent | This defect has been repaired, or repair is unnecessary. Signed before the vehicle is operated again | 396.11(a)(3)(ii) |
| 3 | The next driver, before driving | I reviewed the last report and the certification of repairs is present | 396.13(b), (c) |
Four details that people miss:
Three months from the date the written report was prepared. That is 396.11(a)(4), and it is a package deal: the driver vehicle inspection report, the certification of repairs, and the certification of the driver's review. All three, three months, together. A folder with the reports but no repair certifications is not a compliant DVIR file; it is half of one.
On leased power units and owner-operator equipment, FMCSA guidance is direct: the motor carrier is responsible for retaining each DVIR and the certification of repairs for at least three months. Handing that duty to the owner-operator does not move the obligation off the carrier's USDOT number, and it does not help when the investigator is standing in your office and the paper is in somebody's glovebox in Ohio.
The intermodal side runs on its own track. Under 396.11(b) a driver or motor carrier transporting intermodal equipment reports known damage, defects or deficiencies to the equipment provider at the time the equipment is returned, and the report must carry the carrier's name, the motor carrier's USDOT number, the intermodal equipment provider's USDOT number, a unique identifying number for the item of equipment, the date and time submitted, the defects, and the driver's signature. The provider repairs and certifies, and holds the documentation three months from submission.
Under the letter of the rule, no, and this surprises a lot of owner-operators who have been buying DVIR books for years. 396.11(a)(5) states that the rules in this section shall not apply to a private motor carrier of passengers (nonbusiness), a driveaway-towaway operation, or any motor carrier operating only one commercial motor vehicle.
The obvious question is how a tractor plus trailer is counted, and FMCSA answered it in guidance on 396.11. Asked whether a DVIR is required by a motor carrier operating only one tractor trailer combination, the agency's answer is no: one tractor semitrailer or full trailer combination is considered one motor vehicle. The guidance immediately adds the limit: a carrier operating a single truck tractor and multiple semitrailers which are not capable of being operated as one combination unit would be required to prepare DVIRs.
So the exception is narrower than it looks, and here is what it does not touch:
Our honest advice for a one-truck operation: keep writing them anyway. A three-month file of defect reports with repair certifications and invoices behind them is the cheapest evidence you will ever produce that the truck was maintained, and it becomes mandatory the moment you grow.
Yes, and the answer is now written in two places. 49 CFR 390.32 has since 2018 allowed any person or entity required to generate, maintain or exchange documents under 49 CFR parts 300 to 399 to use electronic methods, and to sign or certify with an electronic signature made using any available technology that otherwise satisfies FMCSA's requirements. On top of that, FMCSA's rule Electronic Driver Vehicle Inspection Reports, published February 19, 2026 at 91 FR 7893 with the amendments credited at 91 FR 7896 (docket FMCSA-2025-0115, RIN 2126-AC89) and effective March 23, 2026, added the permission directly into the DVIR sections: 396.11(a)(6), 396.11(b)(5) and 396.13(d) now each state that the reports may be created and maintained in electronic format in accordance with 49 CFR 390.32.
The conditions in 390.32(d) are where electronic systems fail audits, not the permission. The record must accurately reflect the information otherwise required, be capable of being retained, be accurately reproducible within required timeframes for anyone entitled to access it, be used for the purpose for which it was created, and include proof of consent to use electronic records under 15 U.S.C. 7001(c).
Translated into a vendor conversation: can your platform export three months of DVIRs, with the driver signature, the repair certification and the reviewing driver signature, as readable files, on the day an investigator asks, including for drivers who have left? If the answer involves an account nobody can log into any more, the record is not reproducible and the compliance benefit is theoretical.
At roadside the DVIR is rarely the headline, but it is a fast question with a slow answer if the truck is not organised. What an officer can look at in this area:
What levels of inspection exist and what an officer physically checks at each one is a separate subject, covered in DOT inspection levels explained. If the inspection ends with a sticker on the windshield, the recovery path is in vehicle out-of-service recovery. And the calendar of enforcement pushes, including the annual brake events, is in CVSA Roadcheck and Brake Safety Week.
An investigator is doing something different from an officer. He is not evaluating one truck on one day; he is testing whether the system exists. That is why the same paragraphs show up on the list of acute and critical regulations in Appendix B to 49 CFR Part 385. Acute regulations, per Appendix A to Part 385, are those where noncompliance is so severe as to require immediate corrective action regardless of the carrier's overall controls. Critical regulations are those where noncompliance relates to management or operational controls and indicates a breakdown in them.
| Regulation | What the finding says | Type | Points in a safety audit |
|---|---|---|---|
| 396.11(a) | Failing to require driver to prepare driver vehicle inspection report | Critical | 1 |
| 396.11(a)(3) | Failing to correct out-of-service defects listed by driver in a DVIR before the vehicle is operated again | Acute | 1.5 |
| 396.3(b) | Failing to keep minimum records of inspection and vehicle maintenance | Critical | 1 |
| 396.17(a) | Using a commercial motor vehicle not periodically inspected | Critical | 1 |
| 396.17(g) | Failing to promptly repair parts and accessories not meeting minimum periodic inspection standards | Acute | 1.5 |
| 396.9(c)(2) | Requiring or permitting the operation of a motor vehicle declared out-of-service before repairs were made | Acute | 1.5 |
Now the arithmetic, from Appendix A to Part 385, which governs the new entrant safety audit. Each instance of noncompliance with an acute regulation is 1.5 points; each instance with a critical regulation is 1 point. Parts 393 and 396, plus inspection data for the last 12 months, make up Factor 4, Vehicle. If the combined acute and critical violations inside one factor reach three or more points, the carrier is determined not to have basic safety management controls for that factor. Separately, if the carrier had at least three roadside inspections in the twelve months before the audit and its vehicle out-of-service rate is 34 percent or higher, one more point is added to the vehicle factor. Inadequate controls in at least three separate factors means corrective action is required to avoid revocation of new entrant registration or suspension of provisional authority.
Do the counting on your own file. A carrier that never built a DVIR process at all can pick up 396.11(a) as critical, 396.3(b) as critical, and one acute finding under 396.11(a)(3) for a truck dispatched with an uncorrected out-of-service defect. That is 1 plus 1 plus 1.5, which is 3.5 points in Factor 4 alone. Vehicle paperwork is the cheapest factor to fail and the cheapest to fix, which is exactly why investigators start there.
The three questions we hear investigators open with, in this order:
Roadside violations are weighted by severity inside the Vehicle Maintenance BASIC. These come from the Vehicle Maintenance sheet of FMCSA's SMS Appendix A violations list, version 3.21. The last column is the file's own Violation in the DSMS flag, which decides whether the weight is actually applied in the agency's Data-Driven Safety Management System:
| Violation code | What it means | Violation group | Severity weight | In the DSMS |
|---|---|---|---|---|
| 396.11 | No or inadequate driver vehicle inspection report | Inspection Reports | 4 | Y |
| 396.13(c) | No reviewing driver signature on DVIR | Inspection Reports | 4 | Y |
| 392.7 | No pre-trip inspection | Inspection Reports | 4 | Y |
| 396.17(c) | Operating a CMV without proof of a periodic inspection | Inspection Reports | 4 | N |
| 396.9(d)(2) | Failure to correct defects noted on previous inspection report | Inspection Reports | 4 | N |
| 396.7 | Unsafe operations forbidden | Other Vehicle Defect | 3 | Y |
| 396.9(c)(2) | Operating an out-of-service vehicle | Vehicle Jumping OOS | 10 | Y |
Note the shape of that table. Paperwork violations sit at weight 4, which is not trivial but is survivable. Moving a truck that an officer has stickered sits at 10, the highest weight in the group. The gap tells you where enforcement attention actually is.
Two details in that table are worth reading twice. First, 392.7, "no pre-trip inspection", carries the same weight 4 as a missing DVIR and sits in the same Inspection Reports group: the looking and the writing are separately citable at roadside. Second, the DSMS column is not uniform. 396.11, 396.13(c) and 392.7 are flagged Y; 396.17(c) and 396.9(d)(2) are flagged N. That concerns the agency's internal methodology, not whether the violation lands on the roadside report, where it lands either way and stays visible to brokers and insurers. How the weights turn into a percentile, and where the intervention thresholds sit for Vehicle Maintenance, is worked through in CSA scores explained. If a violation on your record is wrong on the facts, the correction route is the DataQ challenge process.
Keep it in proportion. FMCSA states that conclusions about a carrier's overall safety condition should not be drawn simply from the data displayed in the system. A DVIR problem is a compliance and audit problem first.
Vehicle paperwork does not live alone. The same investigator who reads your DVIR file also looks at how crashes on your record were classified, which is the subject of crash preventability and the CPDP, and at whether your loads were legal, which starts with the bridge formula and axle weights. Seasonal equipment rules that vary from state to state, including traction devices, are in chain laws by state.

No. Under the current text of 49 CFR 396.11(a)(2)(i), drivers are not required to prepare a report if no defect or deficiency is discovered by or reported to the driver. That sentence is in the rule itself and it works the same way for everyone the section covers: there is no property-carrying versus passenger-carrying split anywhere in 396.11 today. It reached that unqualified form through two FMCSA rules credited in the amendment list of the section, 79 FR 75449 published December 18, 2014 and 85 FR 50793 published August 18, 2020 and effective September 17, 2020. Note that the rule removes the paperwork, not the duty: 49 CFR 392.7 still bars driving unless the driver is satisfied the listed parts are in good working order.
They are two different obligations under two different sections. The pre-trip duty lives in 49 CFR 392.7 and 396.13: before driving, the driver must be satisfied the vehicle is in safe operating condition and that the listed parts and accessories are in good working order. The DVIR lives in 49 CFR 396.11 and is a written report prepared at the completion of the day's work listing defects found or reported during that day. FMCSA guidance is explicit that 396.11 does not require a post-trip inspection of the kind described in 396.15; it requires a report of what the day produced. One is looking, the other is writing.
Up to three signatures, in sequence. First, the driver who prepared the report signs it under 396.11(a)(2)(ii); on two-driver operations only one driver needs to sign, provided both agree on the defects identified. Second, the motor carrier or its agent certifies on the report that the defect has been repaired or that repair is unnecessary, before the vehicle is operated again, under 396.11(a)(3)(ii). Third, the next driver signs under 396.13(c) to acknowledge that he reviewed the report and that there is a certification that the required repairs were performed. That third signature does not apply to listed defects on a towed unit that is no longer part of the vehicle combination.
Three months from the date the written report was prepared, under 49 CFR 396.11(a)(4), and that period covers three things together: the driver vehicle inspection report, the certification of repairs, and the certification of the driver's review. FMCSA guidance adds that for leased vehicles and owner-operator equipment the motor carrier is the party responsible for retaining the report and the certification of repairs. Do not confuse this with the neighbouring retention periods: the annual inspection report is kept fourteen months under 396.21(b)(1), maintenance records are kept one year and six months after the vehicle leaves the carrier's control under 396.3(c), and a roadside inspection report copy is kept twelve months under 396.9(d)(3)(ii).
49 CFR 396.11(a)(5) states that the rules in this section do not apply to a private motor carrier of passengers (nonbusiness), a driveaway-towaway operation, or any motor carrier operating only one commercial motor vehicle. FMCSA guidance on 396.11 explains how to count: one tractor semitrailer or full trailer combination is considered one motor vehicle, but a carrier running a single truck tractor with multiple semitrailers that cannot be operated as one combination is required to prepare DVIRs. The exception is narrow and it disappears the day you add a second unit, and it never touches 392.7, 396.3, 396.13, 396.17 or the annual inspection.
Yes. 49 CFR 390.32 has allowed electronic records and electronic signatures for retained documents across 49 CFR parts 300 to 399 since 2018, and FMCSA's rule Electronic Driver Vehicle Inspection Reports, published February 19, 2026 at 91 FR 7893 (amendments credited at 91 FR 7896, docket FMCSA-2025-0115) and effective March 23, 2026, wrote the permission directly into 396.11(a)(6), 396.11(b)(5) and 396.13(d). The conditions in 390.32(d) still apply: the record must accurately reflect the information otherwise required, be capable of being retained, be reproducible within the required timeframes for anyone entitled to access it, and include proof of consent to use electronic records as required by 15 U.S.C. 7001(c).
49 CFR 396.11(a)(1) lists eleven items the report must cover at least: 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. The report must also identify the vehicle and list any defect or deficiency discovered by or reported to the driver that would affect the safety of operation or result in a mechanical breakdown. If a driver operated more than one vehicle during the day, a separate report is prepared for each vehicle. FMCSA guidance also accepts a multi-day report form, provided every item and certification required by 396.11 and 396.13 appears on it.
Whether the loop closes. In the list of acute and critical regulations in Appendix B to 49 CFR Part 385, failing to require a driver to prepare a driver vehicle inspection report under 396.11(a) is a critical violation, and failing to correct out-of-service defects listed by a driver in a DVIR before the vehicle is operated again under 396.11(a)(3) is an acute violation. In a new entrant safety audit, Appendix A to Part 385 assesses 1.5 points for each instance of noncompliance with an acute regulation and 1 point for each critical one, and three points inside a single factor means the carrier is determined not to have basic safety management controls for that factor. Part 396 sits in Factor 4 together with Part 393.
