Fatal 18-Wheeler and Tractor-Trailer Crashes in Sherman County, Texas

You’re reading this because someone you love didn’t come home from one of the freight corridors that cuts through Sherman County. Maybe it was on U.S. Highway 287 where the long-haul semis run between Amarillo and Dalhart. Maybe it was on State Highway 15 where the grain trucks move between Stratford and Spearman. Maybe it was on a county road where an oilfield water hauler lost control in the Panhandle dust. Wherever it happened, an 80,000-pound tractor-trailer changed everything for your family, and the carrier that ran it already has lawyers working to minimize what they owe you.

We don’t let that happen.

The Reality of an 18-Wheeler Crash on Sherman County’s Roads

Sherman County sits at the crossroads of two major freight patterns. U.S. Highway 287 carries the north-south truck traffic between Amarillo and the Oklahoma Panhandle, while State Highway 15 and the county’s farm-to-market roads handle the east-west grain and livestock hauls. The oilfield service trucks running between Stratford and Spearman add another layer—water haulers, sand haulers, and frac spread convoys that move through the county’s rural corridors with the same urgency as the long-haul semis on 287.

When a crash happens here, it’s not just another accident. It’s a collision between an 80,000-pound commercial vehicle operating under Federal Motor Carrier Safety Regulations and a family that never expected to become part of Texas’s commercial-vehicle fatality statistics. The Texas Department of Transportation’s Crash Records Information System (CRIS) recorded 4,150 traffic fatalities in Texas in 2024—one every two hours and seven minutes. Rural crashes like those in Sherman County are 2.66 times more likely to be fatal than urban ones, and the Panhandle’s long EMS response times and limited trauma access only compound the risk.

We know these roads. We know the carriers that run them. And we know what the law requires them to do—and what happens when they ignore it.

What Texas Law Gives Your Family After a Fatal Truck Crash

Texas Civil Practice and Remedies Code Section 16.003 gives you exactly two years from the date of the fatal injury to file a wrongful-death action. That clock started the day of the crash, whether or not the carrier’s insurer has returned your calls. Under Section 71.004, you—along with any surviving spouse, children, or parents—hold an independent statutory claim. The estate also has a separate survival action under Section 71.021 for the pain and mental anguish your loved one endured between injury and death.

These aren’t just legal technicalities. They’re the structure Texas law provides to hold the carrier accountable. And they’re the reason the carrier’s lawyers have been working since the night of the crash.

The Federal Regulations the Carrier Is Supposed to Follow

The Federal Motor Carrier Safety Regulations (FMCSR) govern every aspect of how commercial vehicles operate in Sherman County. These aren’t suggestions—they’re the rules the carrier is required to follow, and violations can support negligence per se under Texas law.

  • Driver Qualifications (49 C.F.R. Part 391): The carrier must verify the driver’s commercial license, medical certification, and employment history. If they hired a driver with a history of hours-of-service violations or preventable crashes, that’s negligent hiring.
  • Hours of Service (49 C.F.R. Part 395): Property-carrying drivers are limited to 11 hours of driving within a 14-hour duty window, after 10 consecutive hours off duty. The electronic logging device (ELD) records every minute the truck moves—but we’ve seen carriers falsify logs to hide violations.
  • Vehicle Inspection and Maintenance (49 C.F.R. Part 396): The carrier must perform regular inspections and repairs. Brake failures, tire blowouts, and lighting defects are all preventable—and all support liability.
  • Cargo Securement (49 C.F.R. Part 393): Improperly secured loads can shift or spill, causing rollovers or multi-vehicle pileups. If the crash involved a grain truck, livestock hauler, or oilfield service vehicle, cargo securement is a critical factor.
  • Drug and Alcohol Testing (49 C.F.R. Part 382): Post-accident drug and alcohol screens are mandatory. A positive result can open the door to punitive damages under Texas Civil Practice and Remedies Code Chapter 41.

We pull the carrier’s Safety Measurement System (SMS) profile, the driver’s Pre-Employment Screening Program record, and the prior preventability determinations before discovery even begins. If the carrier ignored red flags in the driver’s history or the truck’s maintenance file, we’ll find it.

The Defendants Beyond the Driver

Most personal injury firms stop at the driver. We don’t.

In a Sherman County truck crash, the liable parties often include:

  • The motor carrier employer (vicarious liability and direct negligence for hiring, training, and supervision)
  • The freight broker (negligent selection under cases like Miller v. C.H. Robinson)
  • The shipper (if they directed unsafe loading or scheduling)
  • The maintenance contractor (if they performed inadequate repairs)
  • The parts manufacturer (if a defective component contributed)
  • The road designer or TxDOT (if a roadway defect contributed, under the Texas Tort Claims Act)
  • The municipality (if municipal infrastructure contributed)
  • The parent corporation (under alter-ego or single-business-enterprise theory)

For example, if the crash involved an oilfield water hauler, we’d pursue the service company (Halliburton, Schlumberger, or the subcontractor), the operator on the lease, and the shipper that arranged the haul. If it involved a grain truck, we’d look at the cooperative or processor that directed the load. And if the crash happened on a county road with known safety issues, we’d examine whether the county or TxDOT shares liability.

How Texas Pattern Jury Charges Submit Damages to a Jury

A Sherman County jury will decide your case based on the questions submitted under the Texas Pattern Jury Charges (PJC). These aren’t abstract legal concepts—they’re the specific questions the jury will answer, and we build the case around them from day one.

  • PJC 27.1 (General Negligence): Did the carrier’s negligence proximately cause the crash?
  • PJC 27.2 (Negligence Per Se): Did the carrier violate a federal or state regulation, and was that violation a proximate cause of the crash?
  • PJC 5.1 (Gross Negligence): Did the carrier act with malice or conscious indifference to the safety of others? If so, exemplary damages may apply.

The damages categories under Texas law include:

  • Past and future medical care (for survival actions)
  • Past and future lost earnings and lost earning capacity
  • Past and future physical pain
  • Past and future mental anguish
  • Past and future physical impairment
  • Past and future disfigurement
  • Loss of consortium (for the spouse)
  • Loss of companionship and society (for parents and children)
  • Pecuniary loss (in wrongful death cases)
  • Exemplary damages (if gross negligence is proven)

For a family in Sherman County, these damages aren’t just numbers on a page. They represent the lifetime of care your loved one would have needed, the income they would have earned, and the pain they endured in their final moments. We document each category with medical experts, vocational experts, and economists so the jury sees the full picture.

The Carrier’s Defense Playbook—and Our Answer

The carrier’s lawyers have a script. They’ll argue:

  • “The driver did nothing wrong.” (We subpoena the ELD data, dispatch records, and prior preventability determinations to prove otherwise.)
  • “The crash was unavoidable.” (We hire accident reconstructionists to show how proper braking, speed, or training could have prevented it.)
  • “You were partially at fault.” (Texas follows modified comparative negligence under Chapter 33, but even at 50% fault, you recover. We push fault back where it belongs.)
  • “Your injuries aren’t serious.” (We document every symptom, from delayed-onset TBI to chronic pain, with treating physicians and independent experts.)
  • “The evidence was destroyed.” (We send preservation letters within 24 hours to lock down the ELD, dashcam, and maintenance records before they disappear.)

Lupe Peña, our associate attorney, spent years on the other side of these cases. He knows the tactics because he used them. Now, he defeats them.

The Two-Year Clock Under Section 16.003

The carrier’s insurer is counting on you to wait. They know that under Texas Civil Practice and Remedies Code Section 16.003, you have exactly two years from the date of the fatal injury to file a wrongful-death action. After that, the case dies procedurally, and the carrier walks away from a viable claim.

The clock doesn’t stop while you grieve. It doesn’t stop while you’re waiting for the police report or the autopsy results. And it doesn’t stop while the carrier’s adjuster offers you a lowball settlement.

We don’t let the clock run out. We file early to force discovery, set depositions, and make the carrier carry the cost of delay.

How Attorney 911 Approaches Your Sherman County Case

We’ve been representing Texas families in commercial-vehicle cases since 1998. Ralph Manginello, our managing partner, has federal court experience and 27 years of trial practice. Lupe Peña brings an insider’s knowledge of how insurance companies value claims—and how to push past their algorithmic ceilings.

Here’s what we do in the first 48 hours:

  1. Send preservation letters to the carrier, broker, shipper, and any third-party telematics provider, identifying the ELD, dashcam, dispatch records, and maintenance files.
  2. Pull the FMCSA records—the carrier’s Safety Measurement System profile, the driver’s Pre-Employment Screening Program report, and the prior preventability determinations.
  3. Deploy an accident reconstructionist to the scene if needed.
  4. Photograph the vehicles before they’re repaired or scrapped.
  5. Identify all liable parties—not just the driver.

We don’t wait for the carrier to hand over evidence. We preserve it before they can destroy it.

What Your Case Is Worth in Sherman County

The value of your case depends on:

  • The carrier’s hours-of-service compliance (or violations)
  • The driver’s prior preventability determinations
  • The maintenance file on the truck
  • The speed and physical evidence at the scene
  • The survivor’s medical record (for survival actions)
  • What the Sherman County jury pool has historically valued

Texas juries have returned nine-figure verdicts against carriers when the evidence shows gross negligence—falsified logs, ignored maintenance, or a pattern of preventable crashes. The carrier’s insurer knows this. That’s why they’ll offer a lowball settlement early.

We don’t accept the first offer. We calculate the full value of your claim—including future medical needs, lost earning capacity, and the pain your loved one endured—before we negotiate.

We’ve recovered millions for Texas families, including:
