At the moment of a serious truck crash on I-40 or I-27, the trucking company’s rapid-response team is often already moving. Their adjusters, attorneys, and fleet consultants know exactly what data the truck carries, how long it lasts, and what it can prove. The driver who just hit you is an employee of an organization that has handled this before. Most crash victims are focused, rightly, on getting medical care. What they don’t realize is that the most consequential evidence in their case isn’t a photo they can take with their phone. It’s locked inside the truck’s own systems, and it has an expiration date.
Amarillo sits at the intersection of I-40 and I-27, a freight crossroads that moves tens of thousands of vehicles daily through the Texas Panhandle. TxDOT’s Amarillo District estimates I-40 carries between 45,000 and 65,000 vehicles through the area on any given day, a significant portion of them commercial trucks hauling loads the original roadway wasn’t built to handle. That volume means crashes happen here, and it means the trucking companies operating this corridor are experienced at protecting themselves after one.
At Wood Law Firm LLP, our attorneys have over 40 years of combined experience preparing these cases for trial. What follows is an honest explanation of which evidence actually controls the outcome of a Texas truck accident claim, why some of it disappears within days, and what Texas law requires to preserve it.
The Evidence That Disappears in Days, Not Months
Most of the objective evidence in a truck accident case doesn’t come from the scene. It comes from the truck itself, and it doesn’t wait around.
Event Data Recorders
Event data recorders, often called black boxes, capture the truck’s speed, braking force, throttle position, and steering input in the seconds immediately before impact. This data is stored on a continuous loop, and normal truck operation can overwrite it within days or weeks. If no one acts quickly to image the device, the record of exactly how fast the driver was traveling and whether they applied the brakes before the collision can simply cease to exist.
Electronic Logging Devices
Federal Motor Carrier Safety Administration (FMCSA) regulations have required most interstate commercial trucks to use electronic logging devices (ELDs) since December 2017. ELDs record driver hours, location history, and on-duty status. The raw data is needed to determine whether the driver exceeded the hours-of-service (HOS) limits that govern how long a commercial driver can operate without rest. A driver who has been behind the wheel for 11 hours in a 14-hour window and then crashes has a compliance problem that ELD records make undeniable. Those records can also be erased or purged through routine company data practices.
Dashcam & Onboard Camera Footage
Dashcam and onboard camera footage is among the most fragile evidence of all. Many carriers operate cameras that run on short retention cycles, sometimes as brief as 48 to 72 hours. Without a documented demand for preservation, this footage can be recorded over before anyone outside the company ever knows it existed.
Why the Police Report Isn’t the Whole Case
The CR-3 crash report is often the first document a truck accident victim hears about. It’s genuinely useful, just not in the way most people assume.
Texas Transportation Code section 550.062 requires the investigating officer to file a written CR-3 with TxDOT within 10 days of a crash involving injury, death, or at least $1,000 in property damage. For a commercial truck crash, the CR-3 typically captures the carrier’s identity, their DOT number, and the basic sequence of events as the officer observed and documented them. That’s valuable as an investigative starting point, and it’s often the first documented link between the truck and the company responsible for it.
What the CR-3 can’t do is win a case in court. Under Texas Transportation Code section 550.066, certain collision report information is inadmissible as evidence in a civil trial. The officer’s conclusions about fault, any noted violations, and the narrative of events are excluded from what a jury ever sees. The report matters for identifying parties, opening avenues of investigation, and providing context during negotiations. It doesn’t replace objective data from the truck’s own systems, witness testimony, or expert analysis of the physical evidence.
What Texas Law Actually Says About Destroyed Evidence
If a trucking company destroys or loses evidence after a crash, Texas courts don’t automatically punish them. The legal standard is more demanding than that, and understanding it explains why acting early is so important.
In Brookshire Brothers, Ltd. v. Aldridge (2014), the Texas Supreme Court established the framework governing spoliation, the term for a party’s failure to preserve evidence that should have been kept. Under that framework, a company’s duty to preserve evidence arises when it knows or reasonably should know that litigation is more than an abstract possibility. A crash serious enough to injure someone will almost certainly trigger that duty.
The court also limited the harshest remedy available (a spoliation jury instruction that tells jurors to assume the destroyed evidence was harmful to the company) to situations involving intentional concealment or negligent destruction that genuinely prevents a party from presenting its claim. That standard has a practical consequence: a spoliation letter sent immediately after the crash, addressed to the carrier, its insurer, and any relevant third parties, creates a documented record proving the company knew litigation was anticipated. Once that notice exists, any subsequent destruction of ELD records, dashcam footage, or maintenance logs becomes much harder for the company to characterize as routine data management.
How the Right Evidence Affects What You Can Recover
Evidence in a Texas truck accident case isn’t just about proving the driver made a mistake. It’s about determining how fault is allocated, and in Texas, that allocation has a hard cutoff that determines whether you recover anything at all.
Texas follows modified comparative negligence under the Civil Practice and Remedies Code. If a jury assigns 51% or more of the fault to the injured person, that person recovers nothing, regardless of how serious their injuries are. Evidence that undermines your account of what happened isn’t just a problem for reducing your damages. It can eliminate your recovery entirely. Objective data from the truck’s black box, ELD records showing fatigue, and traffic camera footage establishing lane position all shift fault attribution in ways that a verbal account of events can’t.
Beyond the driver’s own negligence, several categories of evidence extend liability to the trucking company itself:
- Driver qualification files (DQFs) contain the driver’s employment application, license verification, road test results, prior employer references, and drug testing history. FMCSA regulations require carriers to maintain these files, and gaps or violations in them support a negligent hiring or retention claim against the company directly.
- Maintenance and inspection records document the carrier’s compliance with federal vehicle inspection requirements. Deferred brake repairs, ignored tire wear, or skipped annual inspections connect a mechanical failure at the time of the crash to decisions made long before it.
- Cargo manifests and load documentation identify who loaded the truck and whether cargo was secured according to FMCSA standards. An improperly loaded trailer that shifts and causes a rollover creates liability that may extend to the cargo loader, not just the driver or carrier.
Together, these records can pull multiple parties into a claim, each with their own insurance coverage and their own exposure for the harm caused.
What to Do Right After a Crash
No post-crash checklist substitutes for legal guidance, but a few concrete steps in the first 24 to 48 hours can protect the evidence that matters most.
Document What You Can at the Scene
Photograph the truck, its trailer, license plates, the DOT number on the cab door, and any visible damage to both vehicles. Get the driver’s name, carrier name, and insurance information in writing.
Note Any Witnesses
Names and phone numbers from bystanders who stopped or people in nearby vehicles can be critical if the driver or carrier later disputes the sequence of events.
Seek Medical Care Immediately
Beyond the obvious health reasons, prompt medical documentation establishes a direct connection between the crash and your injuries that delayed treatment can complicate later.
Contact an Attorney Before Speaking with the Carrier’s Insurer
Recorded statements made in the days after a crash, when you may still be dealing with pain, shock, or incomplete information about your injuries, can be used to limit what the carrier pays. Our truck accident attorneys can ensure a spoliation letter goes out before the most fragile digital evidence is overwritten.
Why Evidence Preservation Can’t Wait
The trucking companies running freight through this corridor have legal and claims teams designed to manage their exposure. The evidence with the most influence over a Texas truck accident claim (ELD records, EDR data, dashcam footage, and driver qualification files) is precisely the evidence those companies have no obligation to volunteer, and some of it may be gone before a case ever reaches formal litigation. Having equally prepared legal representation from the outset isn’t a strategic luxury. It’s often the difference between a fully documented case and one built around gaps.
