What maintenance records matter after an 18-wheeler crash in North Carolina?
September 2026: published.
Three categories of record carry most of the weight after a mechanical-failure truck crash. The maintenance file, the driver vehicle inspection reports, and the periodic inspection report each run on a separate retention trigger under 49 CFR Part 396, and the shortest expires in three months.
By the time most people call an attorney about a truck wreck, the trailer is back in service and the tractor has been repaired or sold. The paper is a separate question. A maintenance file does not get destroyed in the crash, and it does not ride in the cab.
It sits where the vehicle is housed or maintained, until the rule stops requiring it, and that day is usually sooner than people expect.
At a glance
- The maintenance file identifies the vehicle, records the nature and due date of the inspection and maintenance operations to be performed, and records each inspection and repair with its date and nature, under 49 CFR 396.3(b).
- A driver vehicle inspection report is kept three months, under 49 CFR 396.11(a)(4). The periodic inspection report, commonly called the annual inspection report, is kept fourteen months, under 49 CFR 396.21(b)(1).
- A jury may infer that evidence lost or destroyed by a party who had notice of a potential claim would have been damaging to that party, under N.C.P.I. Civil 101.39.
What maintenance records does a trucking company have to keep?
A motor carrier keeps a maintenance file on each vehicle it controls for thirty consecutive days, a driver vehicle inspection report for any day a defect was found, and a report of the periodic inspection, commonly called the annual inspection.
- The file identifies the vehicle by company number, make, serial number and year, under 49 CFR 396.3(b)(1).
- It carries the nature and due date of each inspection and maintenance operation to be performed, plus a record of inspections, repairs and maintenance showing date and nature, under 49 CFR 396.3(b)(2) and (b)(3).
- A driver reports in writing at the completion of each day's work on each vehicle operated, so a tractor and a trailer are reported separately, covering service brakes and trailer brake connections, parking brake, steering, lights, tires, coupling devices, and wheels and rims, under 49 CFR 396.11(a)(1) and (a)(2)(i).
Exception: Where no defect was found or reported, no written report is required that day, so a missing day is not necessarily a regulatory gap, though it can still matter factually. Section 396.11 also carries several exceptions, including one for a carrier operating only one commercial motor vehicle, under 49 CFR 396.11(a)(5).
According to 49 CFR 396.3, 396.11 and 396.21, Federal Motor Carrier Safety Administration, as of September 2026.
The maintenance file is the record left out of a written demand most often. I see a lot of truck cases where the request goes out for the crash report and the driver logs and stops there. Asked a year later, the carrier can say truthfully that it kept what the rule required.
What can a brake or tire record show that a crash report does not?
Inspection and repair records measure the truck against published minimum standards, and a crash report does not. Appendix A to 49 CFR Part 396 sets the point at which a component fails.
- A steering axle tire fails below 4/32 inch of tread at any point on a major tread groove, and every other tire fails below 2/32 inch, under Appendix A, item 10.
- A brake is rejected where pushrod stroke exceeds the readjustment limit for that chamber type, measured with the engine off, reservoir pressure at 80 to 90 psi and the brakes fully applied, under Appendix A, item 1.a.(5).
- Air drum lining on a non-steering axle fails below one quarter inch at the shoe center, under Appendix A, item 1.a.(6).
- Before the vehicle is operated again, the carrier repairs any listed defect likely to affect safe operation and certifies on that same report that it was repaired or that repair was unnecessary, under 49 CFR 396.11(a)(3).
Exception: Appendix A states the standard for the inspection. Whether a component that passed on that date still met it at the moment of a crash is a question of fact.
According to Appendix A to 49 CFR Part 396 and 49 CFR 396.11, Federal Motor Carrier Safety Administration, as of September 2026.
Two of those documents do work together that neither does alone. A driver writes down that the brakes are out of adjustment, and somebody at the company signs the line underneath saying it was repaired. Where the repair never happened, the company wrote both halves of the problem into its own file.
Who keeps these records, and how fast can they disappear?
The carrier keeps most of them, and the retention trigger differs by record type. The maintenance file is tied to control of the vehicle, while the inspection reports run from the date of the report.
| Record | What it may show | Who controls it | Retention floor | Preservation step |
|---|---|---|---|---|
| Maintenance file, 396.3 | Maintenance schedule and every dated inspection or repair | The carrier, where the vehicle is housed | One year while the carrier controls the vehicle, plus six months after it leaves that control | Preservation demand naming tractor and trailer by unit and VIN |
| Driver inspection report, 396.11 | Defects a driver reported on brakes, tires, steering and wheels | The carrier | Three months from the date written | Demand the report and its repair certification together |
| Annual inspection report, 396.21 | That the vehicle was inspected against the Appendix A standards, and the results, including components not meeting them | Whoever was responsible for the inspection | Fourteen months from the date of the inspection report | Ask who performed it, since the carrier may not have |
| Roadside inspection report, 396.9 | Officer-recorded violations and any out-of-service order | The carrier holds a copy, a State agency issued it | Twelve months from the date of the inspection | Request the copy and identify the issuing agency |
Exception: Records of an inspector's qualifications run for the period that individual performs annual inspections for the carrier plus one year, under 49 CFR 396.19(b). Brake inspector qualification evidence runs on its own parallel rule, under 49 CFR 396.25(e). These periods are a floor, not a schedule.
According to 49 CFR Part 396, Federal Motor Carrier Safety Administration, as of September 2026.
The trigger is not the same on every line of that table. The inspection reports run from the date somebody wrote them, and the maintenance file runs on control of the truck, which means it can outlast a sale by only six months. Disposing of a file on the regulatory schedule may satisfy the rule, and it does not by itself answer a separate duty to preserve once litigation is likely.
Do these rules apply to a truck running only inside North Carolina?
Yes for a loaded tractor-trailer. North Carolina adopts the federal motor carrier safety rules for intrastate carriers by administrative rule, and a rig that size sits above the thresholds.
- In interstate commerce, 49 CFR Parts 390 through 397 apply to any vehicle meeting the federal definition of a commercial motor vehicle, under 14B NCAC 07C .0101(a).
- In intrastate commerce, those parts apply at a gross vehicle weight rating or gross combination weight rating of 26,001 pounds or more, and to placarded hazardous material, under .0101(b).
- The inspection and maintenance rules at 49 CFR 396.17 through 396.23 reach further down, to intrastate carrier vehicles over 10,000 pounds GVWR, under .0101(d).
- A carrier may not use a commercial motor vehicle unless every Appendix A component passed inspection within the preceding 12 months and documentation is on the vehicle, under 49 CFR 396.17(c).
Exception: Paragraph .0101(d) reaches 49 CFR 396.17 through 396.23 only, so it does not by itself carry the maintenance file and driver report rules down to every intrastate vehicle over 10,000 pounds. Those follow the broader adoption in .0101(a) and (b).
According to 14B NCAC 07C .0101, North Carolina Office of Administrative Hearings, readopted effective November 1, 2018.
On the stretch of I-40 and I-85 that runs past Burlington and Graham, the trucks in the next lane are a mix of long-haul carriers and companies that never leave the state. The distinction people expect to matter here does not. An inspection certificate is the small sticker saying somebody checked the components against the federal list inside the last year, and a rig this size carries that paperwork either way.
More on how these cases run in Alamance County sits on the Burlington personal injury page.
Why does preserving mechanical evidence early matter in North Carolina?
Because the retention periods are shorter than the deadline to file. A personal injury claim runs three years in North Carolina, and a driver vehicle inspection report can be gone in three months.
- North Carolina gives three years for a personal injury claim, under N.C. Gen. Stat. § 1-52(5).
- A wrongful death claim runs on a shorter two-year period that does not accrue until the date of death, under N.C. Gen. Stat. § 1-53(4). That subsection also bars the death action where the decedent would already have been barred from bringing a bodily harm claim under G.S. 1-15(c) or 1-52(16).
- A jury may infer that evidence in a party's exclusive possession, lost or destroyed while that party had notice of the claim, would be damaging to that party, under N.C.P.I. Civil 101.39. The inference is permissive and does not shift the burden of proof.
- Notice can arise before a complaint is filed. The notes to that instruction state the obligation to preserve arises before filing where a party is on notice that litigation is likely.
Exception: Expiry alone does not settle the question. Where a preservation duty had already arisen, disposing of a record on the ordinary retention schedule can still be treated as loss or destruction in the spoliation analysis, and the instruction itself is permissive rather than automatic.

A preservation letter is the cheapest thing that happens in a truck case. We send one when a truck case comes in, naming the tractor and the trailer and the records by rule number, so nobody argues later about what the company knew. It moves the question onto what the company did after it was told.
The truck accident practice page covers the wider picture in these cases, including who can be responsible when equipment fails.
The evidence clock is shorter than the filing deadline
None of this is hidden. The rules are published, the carrier knows them, and the periods run whether or not anybody has hired an attorney. What changes from case to case is how quickly somebody asks.
