Evidence Required to Prove Liability in a Commercial Truck Accident Claim

A commercial truck accident can lead to devastating injuries and significant financial losses. Unlike a standard car accident, proving liability in a truck collision is often more complex due to the multiple parties that may be involved. Establishing fault requires strong evidence that demonstrates how the crash occurred and who was responsible. This evidence must show not only negligence but also how that negligence directly caused harm.

At The Law Firm of Chaile Allen, we understand the challenges involved in proving liability in a truck accident claim. With years of litigation experience in Texas, we know what it takes to gather the necessary evidence and build a compelling case. If you or a family member has been injured in a truck accident, we may be able to help you recover the compensation you need.

Police Reports and Official Documentation

One of the first and most critical pieces of evidence in a commercial truck accident case is the police report. Texas law requires drivers to report an accident that results in injury, death, or significant property damage, and failing to do so can result in a fine of $1,000 or more. When law enforcement arrives at the scene, they conduct an initial investigation, interview witnesses, and document key details about the crash. Their report may include statements from the truck driver, other motorists, and bystanders, as well as diagrams or descriptions of vehicle positions and damage.

Additional documentation, such as citations issued to the truck driver, can further support a claim of negligence. If the driver violated traffic laws—such as running a red light or driving under the influence—this information can strengthen a case against them. In some cases, federal or state regulatory agencies may also conduct investigations, particularly if the truck was carrying hazardous materials or exceeded weight limits.

Beyond police reports, accident victims may be able to use other forms of official documentation. Medical records linking injuries directly to the crash, repair estimates for vehicle damage, and employment records showing lost wages all help to illustrate the impact of the accident. When combined, these records create a clear picture of the damages suffered.

Truck Driver Logs and Company Records

Trucking companies and their drivers must follow strict regulations set by the Federal Motor Carrier Safety Administration (FMCSA). These rules limit the number of hours a driver can operate a truck without taking a break, ensuring fatigue does not contribute to accidents. Evidence such as driver log books, electronic logging device (ELD) data, and fuel receipts can reveal whether a driver was on the road longer than allowed, which may indicate negligence.

Beyond hours-of-service violations, other company records can help establish liability. Maintenance logs can show whether the trucking company failed to inspect or repair the vehicle properly. If a truck’s brakes, tires, or lights were not maintained according to safety standards, the company may be held responsible for contributing to the crash. Similarly, employment records may indicate whether the driver had a history of reckless driving or previous violations that should have raised red flags.

In some cases, the trucking company’s hiring and training practices come into question. If a company knowingly hired an unqualified driver or failed to provide proper training, they may share responsibility for the crash. Obtaining these records often requires legal action, as trucking companies may be reluctant to release potentially damaging information.

Black Box Data and Physical Evidence

Most commercial trucks are equipped with event data recorders (EDRs), commonly referred to as “black boxes.” These devices capture critical information about the truck’s speed, braking patterns, and engine performance leading up to an accident. Black box data can help reconstruct the moments before impact and provide objective evidence of driver behavior.

Physical evidence from the crash scene is also essential in proving liability. Skid marks, debris, and the final resting positions of vehicles can help accident reconstruction specialists determine what happened. In cases where mechanical failure is suspected, forensic analysis of truck components—such as brakes, tires, and steering mechanisms—can reveal defects or maintenance issues.

In addition to black box data, some trucks are equipped with dashboard cameras that record video footage of the road ahead. If available, this footage can provide undeniable proof of what occurred in the seconds before the collision. This type of evidence is particularly useful when there is conflicting testimony from drivers and witnesses.
