Hit by an 18-Wheeler in Dallas–Fort Worth? Telematics Can Prove the Trucking Company Knew

By The Stone Law Offices

You did nothing wrong. You were driving on I-35E, I-20, I-30, or LBJ Freeway in Dallas–Fort Worth when an 80,000-pound 18-wheeler changed your life in a single second. Now you are facing surgeries, missed paychecks, stacked-up medical bills, and an insurance adjuster who already seems to be working against you.

Here is what the trucking company does not want Texas crash victims to know: its own truck was recording everything. Modern fleets run on telematics, and that data can show exactly how fast the driver was going, when (or whether) they braked, how long they had been behind the wheel, and whether the company ignored warning signs long before your crash.

That evidence can prove who is responsible. If a truck driver or trucking company caused your injuries, you may be entitled to compensation under Texas law for medical care, lost income, pain and suffering, and the future you were promised. But that data can be overwritten in weeks, and your Texas filing deadline is already running.

Understanding Truck Accident Liability in Texas

Texas has more large-truck crash deaths than any other state year after year, according to NHTSA and FMCSA data, and the I-35 and I-20 freight corridors through Dallas–Fort Worth carry some of the heaviest truck traffic in the country. In 2026, investigators no longer rebuild these crashes from skid marks and shaky memories. Data-driven fleets monitor drivers in real time, and that digital trail can hold both the driver and the company accountable.

What telematics records

Telematics systems combine GPS, the engine control module (the truck's "black box"), electronic logging devices (ELDs), forward- and driver-facing cameras, and AI safety software. Together they capture:

•         Speed, location, and exact route, second by second

•         Hard braking, sudden acceleration, and lane departures

•         Hours behind the wheel and rest breaks taken (or skipped)

•         Engine faults, brake warnings, and overdue maintenance alerts

•         Distraction and fatigue alerts flagged by in-cab cameras

How the data proves fault

When a driver says "I was going the speed limit" and the data says 72 mph in a 55 zone, the data wins. Telematics can show that a driver was speeding, braked too late or not at all, or violated the federal hours-of-service rules in 49 C.F.R. § 395.3, which cap property-carrying drivers at 11 hours of driving within a 14-hour window.

The data can also expose the company. If safety managers received repeated alerts about a driver's speeding, harsh braking, or fatigue and did nothing, that was a business decision. Under Chapter 41 of the Texas Civil Practice and Remedies Code, proof by clear and convincing evidence that a company acted with gross negligence can support exemplary (punitive) damages.

The stakes are enormous. Nationwide, roughly 5,000 to 6,000 people die in large-truck crashes every year, according to NHTSA, and the large majority of them are not in the truck. FMCSA's Large Truck Crash Causation Study found that when the truck was assigned the critical reason for a crash, driver factors such as speed, fatigue, and inattention were responsible about 87% of the time.

Texas deadlines and fault rules

•         2-year statute of limitations. You generally have two years from the date of the crash to file a personal injury lawsuit (Tex. Civ. Prac. & Rem. Code § 16.003). A wrongful death claim must generally be filed within two years of the date of death (§ 16.003(b)). Miss the deadline, and your claim can be lost forever.

•         51% proportionate responsibility bar. Texas uses modified comparative fault (CPRC § 33.001). If a jury finds you 50% or less responsible, you can still recover, reduced by your percentage. If you are found more than 50% responsible, you recover nothing. Expect the trucking company to fight hard to push blame onto you.

•         Chapter 72 commercial vehicle rules. Since 2021, Chapter 72 of the CPRC lets trucking companies split trials into phases and can limit negligent hiring, training, and supervision claims once the company admits the driver was on the job. That makes telematics proof of corporate gross negligence more important than ever in Texas truck cases.

How Insurance Companies Try to Block Your Recovery in Texas

Within hours of a serious 18-wheeler crash in North Texas, many carriers dispatch a rapid-response team of investigators, adjusters, and defense lawyers. Their job is not to help you. It is to protect the company's bottom line.

•         The fast lowball offer. An adjuster calls while you are still in pain and offers a quick check. It rarely covers future surgeries, therapy, or lost earning capacity, and once you sign a release, your claim is over.

•         The recorded statement. They ask "just a few questions" on tape, hoping you will say "I'm fine" or guess at a speed they can twist later. You are not required to give the trucking company's insurer a recorded statement.

•         Blame-shifting. Under Texas's 51% bar, every point of fault they pin on you shrinks your award, and crossing 50% wipes it out. Expect claims that you were speeding, distracted, or cut the truck off.

•         Letting the data disappear. Some telematics platforms overwrite data on a rolling basis. If no one demands that it be preserved, the strongest evidence in your case can quietly vanish.

•         Delay. Stalling until your bills pile up and the two-year deadline approaches is a pressure tactic designed to make you accept less.

How we fight back. Attorney E. Lynette Stone spent years defending national insurance companies, so she knows these tactics from the inside. We take over every communication with the insurer, send preservation demands immediately, retain accident reconstruction and telematics experts, and prepare every case as if it is headed to a Dallas County jury.

Evidence We Preserve Immediately

Federal rules require carriers to keep some records, but only briefly. ELD records and supporting documents must be kept for just six months (49 C.F.R. § 395.8(k)), and driver vehicle inspection reports for only three months (49 C.F.R. § 396.11). Much of the most revealing telematics data is not covered by any federal retention rule at all.

•         Engine control module (black box) data: speed, throttle, brake application, and cruise control status in the seconds before impact.

•         Telematics and GPS history: route, speed patterns, harsh-event alerts, and safety warnings the company received about this driver.

•         ELD and hours-of-service records: proof of fatigue or illegal driving hours.

•         Dash cam and driver-facing camera footage: what the driver saw and what the driver was doing, including phone use or drowsiness.

•         Maintenance and inspection logs: ignored brake, tire, or engine warnings.

•         Driver qualification and training files: prior violations, failed drug tests, and how the company vetted the driver.

•         Cell phone records: calls, texts, and app use at the time of the crash.

•         Dispatch communications: messages showing unrealistic delivery deadlines.

•         Third-party video: TxDOT traffic cameras, nearby businesses, and doorbell cameras, which are often recorded over within days.

Why the spoliation letter matters. Our first step is a formal spoliation-of-evidence (preservation) letter to the trucking company, its insurer, and any telematics vendor, putting them on legal notice to save every byte of data. Under Brookshire Bros. v. Aldridge (Tex. 2014), a Texas court can sanction a party that fails to preserve evidence it had a duty to keep, including in serious cases by instructing the jury about the lost evidence. Without that letter, the company may simply claim the data was "routinely overwritten."
