Preserving Evidence After a Truck Accident in Texas

After a serious truck accident, commercial carriers and their insurers will begin protecting their interests immediately, while injured parties are still receiving urgent medical care. Trucks may be removed from service, electronic data secured by the company, and internal reviews initiated—often before the injured person has had an opportunity to understand what happened or what information exists.

This imbalance matters. In truck accident cases, some of the most important evidence is controlled by the trucking company. It can be altered, overwritten, or lost if it is not preserved promptly. Understanding how quickly this process begins—and what steps can be taken to protect critical information—is often essential to determining fault and pursuing a meaningful injury claim.

At Winocour Law, we represent individuals and families across Dallas, Fort Worth, and throughout East Texas in truck accident cases where early evidence preservation plays a decisive role. This page explains why acting quickly matters, what evidence is most important, and how experienced counsel can help level the playing field after a serious commercial trucking collision.

Why Evidence Disappears Quickly After a Trucking Collision 

Truck accidents frequently trigger rapid responses that can compromise critical evidence. Unlike ordinary car accidents, commercial trucking collisions often involve coordinated corporate and insurance activity within hours of the crash. 

Evidence may be lost through: 

• Vehicle repairs – Trucks are often repaired or returned to service quickly, eliminating damage patterns. 

• Data overwriting – Electronic data from black boxes and Electronic Logging Devices (ELDs) may be overwritten in a short period of time. 

• Corporate response teams – Companies may secure vehicles, remove debris, or limit access to records. 

• Scene alterations – Weather, traffic, and emergency response can unintentionally disturb physical evidence. 

Because of these factors, waiting even a short time can mean losing information that helps explain how and why a crash occurred. 

The Types of Evidence That Strengthen a Truck Accident Lawsuit

Strong evidence is the foundation of any truck accident case. Our attorneys focus on identifying and preserving materials that document driver behavior, vehicle condition, and company practices. Learn more about evidence preservation in here.

Black Box (ECM) and Electronic Logging Device (ELD) Data 

These systems record speed, braking, throttle use, and driver activity. Preserving this data can help clarify what occurred in the moments leading up to impact. 

Driver Logs and Hours-of-Service Records 

Federal rules require accurate tracking of driving hours. Log violations may indicate fatigue or noncompliance with safety regulations. 

Dashcam or Surveillance Footage 

Video footage—from the truck, nearby vehicles, or surrounding businesses—can provide objective insight into lane position, speed, and driver actions. 

Maintenance and Inspection Records 

Maintenance histories may reveal missed inspections or mechanical issues that contributed to the crash. 

Cargo Securement Documentation 

Improperly secured cargo can shift, causing loss of control or rollover events. 

Post-Accident Toxicology Results 

Testing may identify drug or alcohol impairment and help establish whether safety rules were followed. 

“Some of the most important work in a truck accident case happens before a lawsuit is filed. Simply by announcing our representation, we can begin securing the critical evidence that will help accurately evaluate liability and prevent important information from disappearing.” 

—Mike C. Miller, Of Counsel

How Insurance Companies Undermine Claims  

Insurance companies move quickly to protect their interests after a commercial crash. 

Common tactics include: 

• Requesting recorded statements that may later be used to challenge credibility 

• Making early settlement offers that do not reflect the full scope of harm 

• Delaying or disputing medical treatment coverage 

• Arguing comparative negligence to reduce potential recovery 

Retaining legal counsel helps counter these strategies and ensures that evidence—not pressure—drives the outcome. 

Steps to Take Immediately After a Truck Accident 

The steps you take immediately after a truck accident can have a lasting impact on your physical recovery and your legal rights.  

• Seek medical care – Health and documentation come first. 

• Report the accident – Law enforcement reports provide an initial record of the incident. 

• Document the scene – Photographs, road conditions, and vehicle positions can matter later. 

• Gather witness information – Independent accounts often become critical. 

• Preserve physical evidence – Clothing, damaged property, and personal items should be retained. 

• Consult a truck accident lawyer – An attorney can manage evidence preservation and insurer communication while you focus on recovery. 

Legal Tools Used by Attorneys to Preserve Critical Evidence 

Attorneys use formal legal mechanisms to prevent evidence loss, including: 

• Spoliation letters demanding preservation of records and data 

• Preservation orders issued by courts 

• Subpoenas compelling production of logs, footage, and maintenance records 

• FMCSA recordkeeping requirements, which establish minimum retention obligations 

These tools help prevent destruction or alteration of information essential to proving liability.
