Maintenance Records and Commercial Truck Insurance Claims
After a truck accident or cargo claim, one of the first questions an adjuster or plaintiff attorney may ask is: when was this truck last inspected? A documented maintenance history is evidence that the carrier managed the equipment responsibly. An absent or inconsistent record raises the opposite question.
Plain-English summary
Maintenance records do not prevent accidents, but they shape how claims are evaluated and defended. Carriers who build a consistent recordkeeping practice before a loss are in a stronger position than those who try to reconstruct or explain gaps afterward.
FMCSA maintenance program requirements
FMCSA regulations under 49 CFR Part 396 require motor carriers to maintain vehicles in safe operating condition and to keep systematic inspection, repair, and maintenance records. These records include periodic inspection reports, any out-of-service findings, repair documentation, and driver vehicle inspection reports (DVIRs). Carriers subject to FMCSA oversight should treat these as regulatory obligations as well as claim management tools.
How maintenance records enter a claim file
- A brake failure accident: records showing the last brake inspection, any deferred repairs, and driver DVIRs become central to the investigation
- A tire blowout loss: records of tire tread depth, age, and prior replacements may be reviewed
- A cargo rejection due to reefer failure: reefer unit maintenance log, fuel records, and alarm history often drive the analysis
- A mechanical breakdown physical damage claim: maintenance records may affect whether the loss is considered a covered event or excluded wear and maintenance
Reefer maintenance as a separate record
Carriers hauling temperature-sensitive freight should keep reefer maintenance logs separate from the tractor maintenance file. The reefer unit's service intervals, alarm tests, fuel consumption records, and any prior temperature excursions are distinct from the truck's oil changes or brake work. A claim involving spoiled produce or rejected pharmaceutical freight will often focus on the reefer unit's history, not the tractor's.

Questions carriers ask
How long should maintenance records be kept?
FMCSA requires most inspection, repair, and maintenance records to be retained for at least one year while the vehicle is in service and six months after disposition. Open claims or litigation may require longer retention.
Can a cargo claim be affected by missing maintenance records?
Yes. A reefer breakdown cargo claim, for example, may be harder to defend without maintenance and temperature records showing the unit was properly serviced. The absence of records does not automatically cause a denial, but it weakens the carrier's documentation position.
Are driver vehicle inspection reports (DVIRs) part of the maintenance record?
Yes. DVIRs document pre-trip and post-trip findings by the driver. They are part of the FMCSA-required maintenance file and can become relevant in claims where vehicle condition at the time of departure is disputed.
