Truck Crash Evidence: Records That Can Help Explain What Happened

Published November 3, 2026 · by Lenahan Law Firm

TL;DR

  • If your family is trying to understand a serious truck crash, records can help explain what happened, but no single record proves fault.
  • Crash reports, scene photos, witness accounts, electronic driving logs, and maintenance, inspection, or dispatch records may offer different pieces of the account. What exists and what you can obtain varies by case.
  • An attorney can promptly ask a carrier to preserve relevant records. Where electronic logging device rules apply, carriers generally must retain those records and supporting documents for six months. That retention period is separate from the deadline to file a lawsuit.
  • This guide offers general Texas information, not legal advice. An attorney can evaluate your family’s specific circumstances.

Police & Insurers Often Assign Fault after a Collision. They're Often Both Wrong.

Even the best intended, best trained officer is overworked and under resourced. They absolutely do get it wrong. Just because the police report says somebody is at fault does not make it true. Before the day is done, they'll have at least one other call that they have to turn their focus to. Often, the people who can best tell the story are killed or at the hospital.

Insurers are a totally different beast. They want you to believe that what they determine as fault has some legal meaning. It does not. It is often nothing more than an attempt to stiff-arm or underpay you.

But when the cops or the insurer get it wrong, you need to have evidence to fight back with. And evidence disappears very, very quickly.

What "evidence" means after a serious truck crash

A serious truck crash can generate records beyond the police report. The driver and carrier may document the trip, while a maintenance vendor may record work on the truck. Law enforcement may document what officers found at the scene. Each source captures a different part of what happened.

A crash report may contain observations made after the impact, while driving logs may show recorded hours without showing what the driver saw. Photos, witness accounts, inspection records, and dispatch records may help fill in other details. Which records exist and can be obtained varies by case.

Police crash reports and the official record of the scene

A police crash report gives you an official starting point for understanding a truck collision. The investigating officer typically records the location, vehicles involved, road conditions, and statements gathered at the scene. The report may also include a diagram, witness information, and any citations issued.

The officer may arrive after the collision and rely on accounts that differ. A diagram can show where vehicles came to rest without establishing every movement that led to the crash. Even when a report assigns a contributing factor, it does not decide legal fault on its own.

In Texas, you can request a crash report from the Texas Department of Transportation or the investigating law enforcement agency if you meet the applicable access requirements. You may need the crash date and location to find it. An attorney can review the report alongside other available evidence and explain what its findings do and do not establish.

Scene photos, video, and physical evidence

Photos can preserve details that may change when road crews clear the scene, weather affects the roadway, or vehicles are moved. Skid marks, vehicle damage, and the debris field may help an investigator compare accounts of where the vehicles traveled and how they came to rest. A skid mark alone does not establish who caused the collision.

Nearby surveillance cameras and dashcams may capture the approach to the crash or the collision itself, but footage may be unavailable or overwritten. An attorney can promptly ask the people or businesses holding relevant video to preserve it. Families can also keep any photos they took and note who took them, when, and where. Physical evidence and images are most useful when an attorney can compare them with witness accounts and other records.

Witness accounts

An independent witness may describe moments of the collision that photos and records cannot capture. Someone nearby might recall the truck’s position or a traffic signal, but their view may have been blocked or limited to part of the crash. An attorney can compare the account with scene photos, the police report, and other available evidence. No account establishes fault on its own.

Witnesses can become harder to reach as time passes, and memories can lose detail. If you have a witness’s name or contact information, keep it with your crash paperwork and share it with an attorney promptly.

Electronic logging device records and hours-of-service data

When ELD requirements apply, an electronic logging device, or ELD, records a truck driver’s duty status and certain information about vehicle movement. Its records may help an attorney compare the driver’s reported work and rest periods with the timing of a crash. An ELD log cannot, by itself, establish whether the driver was tired or what caused the collision.

Under the federal hours-of-service recordkeeping rule, motor carriers generally must retain drivers’ records of duty status and supporting documents for six months. FMCSA’s ELD retention guidance explains the requirement. The guidance also addresses backup copies and driver privacy. ELD exceptions may affect whether a carrier has ELD records in a particular case.

The six-month retention period is not a deadline for filing a Texas lawsuit. An attorney can review which records may exist and request their preservation promptly.

Maintenance, inspection, and dispatch records

Maintenance records can help an attorney examine the truck’s condition before a crash. Repair invoices and service logs may show when someone reported a problem, what work a mechanic performed, and whether the same issue appeared again. A record of a repair does not, by itself, establish that a defect contributed to the collision.

Inspection records address a different question. An available inspection report may identify a condition noted before the trip. An inspection report describes what someone checked or reported at a particular time, not necessarily the truck’s condition at the moment of impact.

Dispatch records can provide context for the trip. Assignments, schedules, and messages may show the route a carrier planned or the timing it expected. An attorney would need to compare those records with other evidence before drawing conclusions about scheduling pressure.

Maintenance, inspection, and dispatch records may have different retention requirements or be subject to different carrier practices. An attorney can check which records exist and whether they need to be preserved.

Preservation requests and retention rules

An attorney can promptly send the carrier a written request to preserve relevant records, sometimes called a litigation-hold or spoliation letter. The request asks the carrier to keep those records rather than delete them under routine schedules. When a duty to preserve evidence arises in anticipation of litigation, it may require the carrier to keep records beyond their ordinary retention period.

Ordinary retention rules do not set a deadline for filing a lawsuit. The six-month rule for records of duty status and supporting documents does not set the retention period for other truck records or determine how long a family has to bring a claim. Texas’s statute of limitations is a separate legal question. An attorney can review the applicable filing deadline and what preservation steps the circumstances call for.

What a family can do in the days after a crash

Your family can save information it already has without returning to an unsafe scene. Keep the crash report number, paperwork you receive, photos, and any messages about the collision in one place. If a witness offered contact information, write down their name and what they said while the details are fresh. Keep original photos and videos, even if you also make copies to share.

Contacting a Texas truck crash attorney early gives them time to identify records that may need a preservation request. You do not need to determine fault or obtain the carrier’s private records yourself. An attorney can review what is available, request preservation where appropriate, and advise you about the filing deadline.

Frequently asked questions

  • Can one record prove who caused the crash? Usually not. A crash report may describe what an officer observed, while photos, witness accounts, and company records may add context or raise questions. An attorney can review the records together and assess what they support.
  • What if the trucking company does not preserve records? An attorney can investigate what was lost, when it was lost, and whether the company had a duty to keep it. A court may consider a failure to preserve relevant evidence, but the consequences depend on the facts and applicable law.
  • Will every case have the same records? No. Which records exist depends partly on the truck and the carrier’s practices. The investigation and any available photos or video also affect what an attorney can review. Some records may never have been created, while others may no longer be available.
  • Does the six-month ELD retention rule set the deadline to file a lawsuit? No. FMCSA guidance says carriers generally must keep electronic driver logs and supporting documents for six months. That recordkeeping rule is separate from the deadline for filing a Texas claim. An attorney can review the deadlines and preservation needs in a specific case.

Conclusion

A Texas attorney can help your family identify records that may explain a serious truck crash, request their preservation where appropriate, and review the deadline for a claim. No single record establishes fault on its own.
