Truck Accident Investigation: Maintenance Records

San Antonio Personal Injury Lawyers — Investigating Technique: Maintenance Records

Obtaining Maintenance Records After an 18-Wheeler Accident Can Be Crucial to Proving Negligence

The Federal Motor Carrier Safety Administration and the Department of Transportation require commercial trucking companies to maintain detailed records of their day-to-day operations — including pre-employment screening records for drivers and maintenance records for every truck in their fleet. When an accident happens, both categories of records become powerful evidence. They reveal whether the carrier was operating in compliance with federal safety standards or cutting corners in ways that contributed to the crash. After you have been injured in a collision with a commercial truck, gathering this evidence quickly is one of the most important steps your legal team can take.

Trucking companies understand exactly how damaging their internal records can be in a negligence claim. Some will do everything possible to prevent you from obtaining them — and a few will go further, altering or destroying records once they realize an accident is heading toward litigation. That is why having an experienced attorney from our law offices involved immediately after a crash matters so much. We know what records exist, how to request them through formal legal channels, and how to send spoliation correspondence — a legal notice that places the carrier on written notice of their duty to preserve specific documents and prevents them from claiming later that records were destroyed in the ordinary course of business.

What Federal Law Requires Trucking Companies to Keep

Federal regulations require commercial carriers to systematically inspect, repair, and maintain all vehicles in their fleet and keep those vehicles in safe operating condition. The components covered include brake systems, steering mechanisms, the vehicle frame, coupling and attachment parts, tires, and all safety-related equipment. Records of every maintenance and repair must be retained for at least one year from the date the work was performed, and for six months after any vehicle is sold or taken out of service.

Drivers are also required to maintain their own mechanical logs as part of their daily records — going through a prescribed checklist that documents brake conditions, steering issues, attachment or coupling problems, and any mechanical concerns they reported to the carrier during their route. Those driver-generated logs are retained alongside the company’s maintenance reports and together form a detailed operational history of any given truck.

How Maintenance Records Drive the Legal Strategy

Maintenance records serve two distinct but equally important functions in 18-wheeler accident litigation. The first is establishing carrier negligence when poor maintenance caused or contributed to the crash. If a driver’s brakes failed and the records show the company missed required inspections, deferred known repairs, or failed to document required maintenance activities, those records establish directly that the carrier breached its duty to keep the vehicle in safe operating condition. That breach becomes a pillar of your negligence claim against the company.

The second function is identifying product liability claims when the records show the opposite — that the carrier did perform proper maintenance but the component failed anyway. When a properly maintained brake system, tire, or steering component fails without warning, the evidence points toward the manufacturer of that part rather than the carrier. Maintenance records showing a history of proper care can support a defective product claim against the manufacturer that runs alongside or instead of a negligence claim against the trucking company. An experienced attorney identifies which theory the evidence supports and builds the claim accordingly.

Why Poor Maintenance Is More Common Than Most People Realize

Federal and state law is clear about what trucking companies must do to maintain their fleets. The reality of compliance is far more troubling. In a two-day inspection conducted by Denton County, Texas law enforcement agencies, only four out of sixty commercial trucks were deemed fully safe and roadworthy. Inspectors found everything from paperwork deficiencies to serious mechanical defects — bad hitching systems, poorly secured cargo, and brake and tire problems severe enough to take vehicles out of service entirely. This was a small sample, but it is representative of the commercial truck traffic that San Antonio drivers share roads with every day.

When a truck that failed such an inspection is later involved in an accident, maintenance records become doubly important. If the records show inadequate maintenance, that history directly supports negligence. If the records claim proper maintenance while the truck failed a physical inspection, that contradiction raises the inference that the records themselves were falsified — which is its own serious legal issue and one that experienced truck accident attorneys know how to develop.

Our lawyers have spent over twenty years litigating commercial truck accident claims in Texas. We know the tactics carriers and their defense teams use — refusing discovery requests, denying the existence of certain records, producing incomplete documentation, and pressuring unrepresented victims into settlements worth far less than their claims. Against an experienced legal team that knows where to look and how to hold carriers accountable under federal law, those tactics are far less effective. If you were hurt in an 18-wheeler accident, do not face the trucking company alone.
