An eastbound pickup lost control on Interstate 20 near Odessa, Texas, on December 30, 2014, crossing a 42-foot grassy median into the path of a Werner Enterprises tractor-trailer. The collision killed seven-year-old Zackery Blake and left three members of his family seriously injured. Shiraz Ali, a trainee driving the Werner truck, had been traveling below the posted speed limit but at a speed the plaintiffs argued was unsafe for the icy roadway. The resulting negligence and wrongful death lawsuit examined the truck driver's decisions, Werner's training practices, and whether a lower traveling speed could have prevented the collision or reduced the injuries.
A Harris County jury initially assigned most of the responsibility to Werner and Ali after hearing accident reconstruction testimony about vehicle speed, braking, roadway friction, and collision avoidance. The Fourteenth Court of Appeals upheld the trial judgment in 2023, but the Supreme Court of Texas reversed that decision on June 27, 2025. The high court found that the pickup driver's sudden loss of control was the sole proximate cause of the injuries, ruling that the evidence did not establish the required legal connection between Ali's conduct and the collision. Rehearing was denied in September 2025, leaving the final judgment in favor of Werner and Ali.
Freezing rain had created hazardous conditions along Interstate 20 near Odessa, Texas, when Zaragoza "Trey" Salinas was driving eastbound with Jennifer Blake and her three children. At approximately 4:30 p.m., Salinas lost control of his Ford F-350, crossed the grassy center median, and entered the westbound lanes, where his pickup collided with a Werner Enterprises tractor-trailer driven by Shiraz Ali. Ali was completing a trainee driving assignment while his trainer, Jeffrey Ackerman, rested in the truck's sleeper berth. The collision killed seven-year-old Zackery Blake, left 12-year-old Brianna Blake with a severe traumatic brain injury and quadriplegia, and caused serious injuries to Jennifer and 14-year-old Nathan Blake. Weather advisories, highway conditions, and reports of earlier accidents along Interstate 20 later became part of the evidence examined during the negligence trial.
Jennifer Blake and Eldridge Moak, acting as guardian of Brianna Blake's estate, brought a civil lawsuit against Werner Enterprises and Shiraz Ali in the 127th District Court of Harris County, Texas, under case number 2015-36666. The plaintiffs alleged that Ali continued driving too fast for the icy conditions and that Werner failed to adequately train and supervise him. They maintained that safer driving decisions before Salinas crossed the median could have prevented the impact or lessened the resulting injuries. Werner and Ali disputed those allegations, arguing that Salinas's sudden loss of control and entry into opposing traffic caused the accident. The Blake family also reached a settlement with Salinas before trial, and Werner and Ali received a credit based on that settlement.
A 25-day trial conducted over six weeks included testimony about winter driving conditions, Werner's driver training program, and the physical movements of both vehicles before impact. The plaintiffs' accident reconstruction expert, James Crawford, analyzed the collision using vehicle damage, crash-scene evidence, and engine-module data, while defense reconstruction expert Andy Irwin addressed a hypothetical collision scenario involving a truck traveling at 15 mph. Trucking safety expert Arthur Atkinson also testified for the plaintiffs about commercial driver training and precautions for operating on icy roads. Under one of the jury's responsibility questions, jurors assigned 70% to Werner employees other than Ali, 14% to Ali, and 16% to Salinas. The jury awarded $89,687,994 in combined damages to Jennifer, Nathan, and Brianna Blake. The trial court entered its final judgment on July 30, 2018, with the amount against Werner exceeding $92 million after prejudgment interest, court costs, and applicable settlement credits.
The Fourteenth Court of Appeals of Texas, sitting en banc, affirmed the trial court's judgment after reviewing challenges to the negligence findings, jury instructions, responsibility allocations, and expert testimony. The appellate majority determined that the evidence supported the jury's conclusion that Ali failed to drive at a speed appropriate for the conditions and that his conduct was a proximate cause of the injuries. It also upheld the admission of Crawford's alternative-speed reconstruction and Atkinson's testimony concerning commercial trucking safety. The court separately rejected challenges to the future medical expense calculations presented through life-care planner Dr. Shelly Savant and forensic economist Robert Johnson. Four justices dissented across two opinions, questioning aspects of Werner's liability and the instructions provided to the jury.
The Supreme Court of Texas granted Werner and Ali's petition for review after the intermediate appellate court upheld the judgment. The defendants challenged the legal basis for finding that Ali's driving caused the injuries, as well as the liability findings against Werner for its own training and supervision practices. They also disputed the jury instructions and allocation of responsibility among the defendants and Salinas. The court agreed to examine those arguments and scheduled oral proceedings for December 3, 2024.
During oral arguments, the parties addressed whether Ali's traveling speed could legally be treated as a cause of the collision and injuries. The plaintiffs relied on evidence that the Werner truck could have avoided the impact under a hypothetical scenario involving a substantially lower speed. Werner and Ali maintained that the pickup crossed the median so suddenly that Ali had insufficient time to avoid the collision once Salinas lost control. The justices examined the difference between proving that an accident might have been avoided under different circumstances and establishing proximate cause, which under Texas law requires that the defendant's conduct be a substantial factor in producing the injury.
The Supreme Court of Texas reversed the appellate judgment and rendered judgment for Werner Enterprises and Shiraz Ali. Chief Justice James Blacklock, writing for the majority, concluded that Salinas's loss of control and sudden movement into opposing interstate traffic was the sole proximate cause of the family's injuries. The majority acknowledged that the evidence supported the possibility that a lower truck speed could have prevented the collision or reduced the injuries, but determined that this did not establish Ali's conduct as a substantial factor under Texas law. The court also rejected the claims against Werner because those claims depended on establishing that Ali's driving proximately caused the injuries. Justice Jane Bland, joined by Justices Jeffrey Boyd and Rebeca Huddle, dissented in part, concluding that the evidence could support some responsibility for Ali based on his speed and that the case should be returned for a new trial rather than resolved entirely in the defendants' favor.
Following the reversal, the Blake family requested that the Supreme Court reconsider its decision. The court denied rehearing on September 26, 2025, leaving the judgment for Werner and Ali unchanged. Three days later, on September 29, the Supreme Court issued its mandate, formally completing the appellate proceedings. The earlier negligence judgment and damages award against Werner and Ali were overturned, and no further proceedings were ordered in the original lawsuit.

Accident Reconstruction Expert Witnesses (Plaintiffs and Defense)
James Crawford (Plaintiffs) examined the circumstances of the collision using physical evidence from the crash scene, the vehicles' final positions, damage patterns, photographs, witness statements, and data recovered from the Werner truck's engine module. He calculated the truck's drag factor to assess its deceleration and testified that ice on the roadway could have reduced its braking performance. Crawford also prepared an accident reconstruction animation showing that, under his hypothetical scenario, the pickup would have crossed the westbound lanes without colliding with the tractor-trailer if the truck had been traveling at 15 mph.
Andy Irwin (Defense) testified as an accident reconstruction expert for Werner Enterprises and Shiraz Ali. He addressed the same hypothetical 15 mph scenario, agreeing that the truck would have stopped before the collision if it had occupied the same position and the surrounding traffic conditions had remained unchanged. Irwin also testified that photographs showing ice accumulation on the Werner truck were consistent with its having traveled through freezing rain.
The experts' testimony addressed the collision mechanics and the potential effect of a lower truck speed. The parties disputed whether those findings established proximate causation under Texas law.
Trucking Safety Expert Witness (Plaintiffs)
Arthur Atkinson (Plaintiffs) testified about commercial truck operations, driver training, and precautions for hazardous winter weather. He described more than 40 years of experience in the trucking industry, including commercial driving, transportation safety management, and consulting. His testimony addressed the Federal Motor Carrier Safety Regulations, state commercial driver's license manuals, and commercial vehicle safety practices.
Atkinson explained that the Texas commercial driver's license manual instructed drivers encountering icy conditions to reduce speed and stop at the first safe location. Based on his understanding of trucking safety guidance, he testified that slowing to a crawl meant traveling approximately 10–15 mph or less. Werner challenged his qualifications and the basis for several opinions, but the Fourteenth Court of Appeals concluded that the trial court had not abused its discretion in admitting the challenged testimony.
Life Care Planning Expert Witness (Plaintiffs)
Dr. Shelly Savant (Plaintiffs) prepared two life-care plans addressing the long-term medical and assistance needs of Brianna Blake, who sustained a severe traumatic brain injury and quadriplegia in the collision. Savant estimated Brianna's life expectancy at 72 years and prepared the plans to cover 56 years of anticipated care, beginning when Brianna was 16 at the time of trial.
The first plan assumed that Brianna would remain at home with medical treatment and attendant care, with estimated expenses of approximately $25.27 million. The second considered care in a residential treatment facility, with projected expenses of approximately $33.58 million. Savant testified that both estimates reflected the cost of the anticipated services at the prices used in her calculations, without adjustments for future inflation or other economic factors.
Forensic Economics Expert Witness (Plaintiffs)
Robert Johnson (Plaintiffs) evaluated the present value of the future medical and assistance expenses identified in Brianna Blake's two life-care plans. He calculated the projected expenses using assumptions about investment returns and the expected rate of increase in medical and nonmedical costs. His analysis applied a 4.4% interest rate, a 5.3% medical inflation rate, and a 3.7% general inflation rate.
Using these assumptions, Johnson reported a present value of approximately $27.07 million for the home-care plan and $43.19 million for the residential-care plan. Werner challenged his qualifications and methodology, arguing that the calculations were unreliable. The Fourteenth Court of Appeals rejected those challenges and found the testimony sufficient to support the jury's future medical expense award. The Supreme Court of Texas subsequently reversed the overall judgment on proximate causation grounds.
Winter Road Conditions and Safe Commercial Truck Speeds
The Werner tractor-trailer was traveling below Interstate 20's posted 75 mph speed limit, but the trial evidence described icy pavement and reduced traction throughout the surrounding area. Ali was driving approximately 50 mph when he applied his brakes and about 43–45 mph when the vehicles collided. Jurors also heard that other accidents had occurred along the interstate before the collision and that Werner's driver training materials addressed operating commercial vehicles in winter weather. The Supreme Court ultimately resolved the dispute through its causation analysis rather than deciding that Ali's traveling speed was appropriate for the conditions.
Physical Evidence Used to Reconstruct the Truck Collision
The reconstruction involved more than estimating the vehicles' speeds at impact. Crawford examined the truck's engine-module data, the location of physical evidence, damage patterns, crash-scene photographs, and the vehicles' movements after the collision. His calculations included the truck's drag factor, which he used to assess its rate of deceleration during braking. The reconstructed sequence also considered the distance traveled by Salinas's pickup while crossing the median and the limited time Ali had to respond.
Driver Reaction Time and Decisions Before the Impact
Evidence presented at trial placed the time between Salinas losing control and the collision at approximately two seconds. Crawford testified that Ali responded appropriately once the pickup began moving toward the westbound lanes, including his decision to apply the brakes. The plaintiffs' negligence claims instead focused on actions taken before that moment, particularly Ali's speed and his decision to continue driving despite worsening conditions. The Supreme Court evaluated those earlier decisions separately from Ali's immediate reaction during the collision sequence.
Lower-Speed Collision Calculations and Legal Causation
Both sides presented reconstruction testimony supporting the conclusion that the collision would not have occurred under a hypothetical scenario in which the Werner truck was traveling at 15 mph from the same position. That finding addressed what could have happened if one factor had changed while the other circumstances remained constant. The Supreme Court nevertheless concluded that the evidence did not establish Ali's driving as a substantial factor in causing the injuries, as required for proximate cause under Texas law. Justice Bland's partial dissent took a different view, reasoning that the evidence could permit a jury to find that the truck's speed contributed to the severity of the family's injuries.
Driver Training, Employer Negligence, and Responsibility
The plaintiffs challenged Werner's training and supervision of Ali, who had limited commercial driving experience and was completing an assigned trip as a trainee. Trial evidence addressed his preparation for winter conditions, safety evaluations, and the company's guidance concerning when drivers should reduce speed or stop. The jury initially found Werner negligent through employees other than Ali and assigned the company a substantial percentage of responsibility under one of the verdict questions. On final review, the Supreme Court concluded that the claims against Werner could not succeed without establishing that Ali's driving proximately caused the injuries, and it rendered judgment for both defendants.
More than ten years after the December 2014 collision, Werner Enterprises, Inc. v. Blake concluded with a final judgment in favor of Werner Enterprises and Shiraz Ali. The trial had examined conflicting negligence arguments, commercial driver training practices, reconstruction calculations, and the family's extensive medical and financial losses. Although the jury returned a damages verdict against the defendants and the Fourteenth Court of Appeals affirmed, the Supreme Court of Texas concluded that Salinas's loss of control was the sole proximate cause of the injuries under the circumstances presented. Justice Bland's partial dissent favored a new trial on the remaining causation questions, but the majority rendered judgment for Werner and Ali. With rehearing denied and the mandate issued in September 2025, the original negligence lawsuit concluded without a further trial or an enforceable damages judgment against the defendants.
What caused the Werner Enterprises truck accident in Texas?
The collision occurred after Trey Salinas lost control of his Ford F-350 on an icy section of Interstate 20 near Odessa on December 30, 2014. His pickup crossed the median into westbound traffic and collided with a Werner Enterprises tractor-trailer. The Supreme Court of Texas ultimately determined that Salinas's loss of control was the sole proximate cause of the injuries under the facts of the case.
How fast was the Werner truck traveling before the collision?
Trial evidence placed the Werner tractor-trailer's speed at approximately 50 mph when driver Shiraz Ali applied the brakes and 43–45 mph at impact. Although these speeds were below the posted 75 mph limit, the plaintiffs argued that the truck was traveling too fast for the icy road conditions. The final ruling addressed whether that speed legally caused the injuries rather than deciding that it was safe.
What happened to the Blake family in the December 2014 crash?
Seven-year-old Zackery Blake died from the collision. His sister Brianna, who was 12 at the time, sustained a severe traumatic brain injury that left her with quadriplegia. Their mother, Jennifer Blake, and 14-year-old brother, Nathan Blake, suffered traumatic brain injuries and other physical injuries. The family pursued damages for wrongful death, personal injuries, and long-term medical care.
How much did the jury award in Werner Enterprises v. Blake?
The jury awarded Jennifer Blake $16.5 million, Nathan Blake $5 million, and Brianna Blake $68,187,994, for a combined award of $89,687,994. After accounting for prejudgment interest, court costs, and settlement credits, the trial court entered a judgment exceeding $92 million against Werner. The Supreme Court of Texas subsequently reversed that judgment in June 2025, leaving the original damages award unenforceable against Werner and Ali.
