Dallas Underride Crash: Your Family’s Rights After a Roof-Shearing Underride Collision with Two 18-Wheelers
If you are reading this at two in the morning, you already know what happened. A passenger vehicle drove underneath one commercial tractor-trailer and then crashed beneath a second 18-wheeler near Linfield Road and the S.M. Wright Freeway corridor in Dallas. The roof was torn off the car. Officials have described the mechanism, and the mechanism — roof shearing consistent with underride — tells us everything about what happened to the person inside that vehicle. We are going to tell you everything we know about what this means legally, what the trucking companies are already doing, and what you need to do in the next 72 hours to protect your family. None of this is theoretical. This is the work we do. This is the fight.

What Happened on the S.M. Wright Freeway: The Underride Mechanism Explained
An underride crash is not a normal collision. In a standard rear-end or side-impact crash, the bumper of the passenger vehicle absorbs the impact against the other vehicle’s bumper or body. The crash energy moves through the car’s crumple zones — the engineered collapse points in the front end, the frame rails, the engine bay — all designed to decelerate the occupant gradually and keep the survival space intact. That is how cars are built to protect you.
An underride crash defeats every one of those safety systems. The trailer of an 18-wheeler sits at a height that lines up with the windshield and roofline of a passenger car — not the bumper. When a car slides underneath a trailer, the trailer’s underside acts like a blade. The windshield, the A-pillars (the structural posts that hold the roof up), the B-pillars, the roof itself — all of it is sheared away. The crumple zones never engage because the trailer floor passes over them. The airbags may deploy, but they deploy into a space that is being crushed above the driver’s head. The seatbelt holds the occupant in position, which means the occupant’s head and upper torso are in the direct path of the trailer’s underside structure.
That is what “roof torn off” means. It means the survival space — the engineered cage that is supposed to protect the person inside — was removed. The injury pattern from this mechanism is consistent with catastrophic traumatic brain injury, decapitation-level cranial-cervical trauma, cervical spine fracture, or fatal injury. This is not a case of whiplash or a broken arm. The physics of underride produce some of the most devastating injuries in all of motor-vehicle crash reconstruction.
The S.M. Wright Freeway corridor runs through southern Dallas, connecting to US-175 and I-45. This is a heavily trafficked commercial truck route — freight moving from the Inland Port distribution region through the Downtown Mixmaster interchange. Linfield Road intersects this corridor in an area with known truck-traffic density and historically problematic merge geometry. The combination of two tractor-trailers at one incident scene suggests either a multi-vehicle chain collision or a roadway design that created sequential underride exposure — a passenger vehicle forced underneath one trailer and then propelled or redirected into a second. Either scenario creates a complex liability matrix involving two separate commercial carriers, each with its own insurance, its own driver, its own regulatory history, and its own corporate defense team.
Two 18-Wheelers, Two Carriers, Two Insurance Towers: Who Is Liable
This is the question that will define the case. When two separate commercial tractor-trailers are involved in one underride sequence, the liability picture is not simple — but it is discoverable, and the answer matters more than in almost any other crash type because the damages are catastrophic and the coverage stacks.
The first 18-wheeler operator and carrier face liability if that truck executed a maneuver — a lane change, a sudden slowdown, a turn — that caused the passenger vehicle to underride. Commercial drivers owe a duty of reasonable care under the circumstances, and Texas negligence law measures breach by the reasonable-person standard. A professional driver operating an 80,000-pound vehicle on a freeway corridor with known merge problems is held to the standard of a trained commercial operator, not an ordinary commuter. If the first truck’s driver violated federal motor-carrier safety regulations — improper lane change, following too closely, failure to maintain lane — that violation can serve as negligence per se, establishing duty and breach as a matter of law.
The second 18-wheeler operator and carrier face separate liability questions. If that truck was stopped in a travel lane, improperly positioned, or created a hazard in the roadway, the operator and carrier face independent negligence claims. If the second truck was struck because the first truck’s negligence propelled the passenger vehicle into it, liability may be shared or shifted between the two carriers — and that allocation is exactly what the evidence will establish.
Under Texas law, respondeat superior is a theory of vicarious liability — not a separate cause of action — by which an employer is held liable for an employee’s negligence committed within the scope of employment. As the court explained in Flores v. Allen Henderschiedt Trucking, Inc., quoting Hansen v. Protective Life Insurance Co.:
“respondeat superior [is] not [a] separate cause[] of action but [is], instead, [a] theor[y] of vicarious liability through which a principal may be held liable for an employee’s negligence.”
This means both carriers are vicariously liable for the negligence of their respective drivers if those drivers were acting within the course and scope of employment at the time of the incident. The carrier cannot simply say “our driver did it, not us” — the law holds the company behind the driver.
But there is also direct liability against the carriers themselves. Under Texas law, a carrier faces direct liability for negligent entrustment if it entrusted its vehicle to a driver who was unlicensed, incompetent, or reckless and the carrier knew or should have known of that status. As the Flores court noted, quoting the standard from Schneider v. Esperanza Transmission Co.:
“To establish liability for negligent entrustment under Texas law, [the plaintiff] must show, among other things, that the driver of the vehicle was unlicensed, incompetent, or reckless; and that the owner entrusted its vehicle to the driver even though it knew or should have known of that status.”
Evidence of prior violations is relevant to this inquiry — though Texas courts require violations that are related, frequent, and recent, not a single isolated ticket. Negligent training, supervision, and retention are also recognized direct-liability theories against motor carriers.
There may also be a products-liability dimension. If either trailer’s underride guard — the rear impact guard — failed to prevent the passenger vehicle from sliding under the trailer, a design-defect or manufacturing-defect claim against the trailer manufacturer is viable. The industry has documented knowledge that standard rear-impact guards are inadequate at higher impact speeds and at overlap angles (where the passenger vehicle hits the guard off-center rather than directly behind it). A guard that meets the minimum federal standard but still fails to prevent underride in a real-world crash is the subject of ongoing safety advocacy and litigation nationwide.
The Federal Underride Guard Rule: What 49 CFR 393.86 Requires
Federal law requires rear-impact guards on most commercial trailers. The regulation states:
“Each trailer and semitrailer with a gross vehicle weight rating of 4,536 kg (10,000 pounds) or more, and manufactured on or after January 26, 1998, must be equipped with a rear impact guard that meets the requirements of Federal Motor Vehicle Safety Standard No. 223.”
This is the minimum federal floor. It establishes that trailers of this size, manufactured after that date, must have a guard. But the regulation is a performance standard — it sets minimum strength and geometry requirements tested under specific conditions. The real-world conditions of a Dallas underride crash — the angle of impact, the speed differential, the overlap between the passenger vehicle and the guard — can exceed those test parameters. A guard that passes the federal test can still fail in a crash that shears a roof off a car.
This is why physical inspection of both trailers and their underride guards is central to the case. We need to know whether each guard was present, whether it was compliant, whether it was damaged or modified, whether it had prior damage that weakened it, and whether it failed in a way that a properly designed guard would not have. That inspection must happen before either carrier repairs, scraps, or releases the vehicle from impound. The evidence on those trailers is perishable — and the carriers know it.
The FMCSA Regulatory Framework: What the Carriers Were Required to Do
The Federal Motor Carrier Safety Regulations, found at 49 CFR Parts 390 through 399, govern commercial motor vehicle operation. These regulations apply to interstate carriers. Intrastate Texas carriers are governed by parallel Texas Department of Public Safety regulations. Several provisions are directly relevant to this crash:
49 CFR 393.86 governs rear-impact guards and underride protection. This is the regulation that requires the guards we just discussed. If either trailer was not equipped with a compliant guard, or if the guard was damaged, removed, or modified, that is a regulatory violation and evidence of negligence.
49 CFR 392.14 prohibits the unsafe operation of a commercial motor vehicle. This is the regulation that addresses reckless or careless driving — the failure to exercise the heightened care required of a professional commercial driver. If either driver executed an unsafe maneuver that created the underride exposure, this regulation was violated.
49 CFR 392.80 prohibits texting and electronic-device use while operating a commercial motor vehicle. Distraction is a leading cause of unsafe lane changes and failure to maintain lane — and the driver’s phone records and in-cab device logs are discoverable.
49 CFR Part 395 governs hours-of-service rules to address driver fatigue. Fatigue impairs reaction time, judgment, and lane maintenance. The Electronic Logging Device (ELD) data from both tractors will show each driver’s hours, rest periods, and whether either driver was operating beyond legal limits.
49 CFR Part 396 governs vehicle inspection and maintenance. If either trailer had a damaged or non-compliant underride guard, the maintenance and inspection records will show whether the carrier knew or should have known — and whether the required pre-trip and post-trip inspections were actually performed.
49 CFR 382.303 governs post-accident drug and alcohol testing. After a fatal or catastrophic crash, commercial drivers must be tested for alcohol within 8 hours and for controlled substances within 32 hours. If the carrier missed those windows, that failure is itself a regulatory violation — and it raises the question of what they were afraid the tests would show.
The minimum financial responsibility for general-freight carriers operating in interstate commerce is $750,000, as established by 49 CFR 387.9, Table 1:
“For-hire (In interstate or foreign commerce, with a gross vehicle weight rating of 10,001 or more pounds) | Property (nonhazardous) | $750,000”
That is the federal floor. Most interstate carriers carry substantially higher limits — typically $1 million in primary coverage plus excess and umbrella layers that can reach $5 million, $10 million, or more. With two carriers involved, the coverage towers stack. The MCS-90 endorsement, required under 49 CFR 387.15, ensures that the motor carrier’s insurance policy provides continuous coverage for public liability — bodily injury and property damage — regardless of certain policy exclusions. This means the insurance cannot simply deny coverage by pointing to a technical exclusion in the policy.
The Evidence Clock: What Exists, Who Holds It, and How Fast It Dies
This is the section that may matter more than any other in the first 72 hours. Every piece of evidence that will decide this case is on a clock. Some of it is already gone. Some of it will be gone by the time you finish reading this page. Here is what exists, who controls it, and how fast it legally disappears.
Electronic Logging Device (ELD) data and Qualcomm/GPS telematics from both commercial vehicles. These systems record each truck’s speed, lane position, braking events, steering input, and maneuvers. They are the digital fingerprint of what each driver was doing in the seconds before and during the underride sequence. This data is critical for apportioning fault between the two carriers. The carriers hold it. They may overwrite or cycle it within 30 to 90 days. The preservation letter must go out immediately — not next week, not after the funeral, not after the insurance company calls. The day you call us is the day that letter goes out.
Event Data Recorder (EDR) / black-box data from both tractors and the passenger vehicle. The EDR captures pre-impact speed, braking application, steering input, and the change in velocity (delta-V) at impact. For the passenger vehicle, the EDR will show whether the driver braked, steered, and what speed they were traveling. For both tractors, the EDR will show whether the commercial drivers braked, changed lanes, or were stopped. This data can be overwritten after subsequent trips — typically within 30 days. A spoliation letter demanding preservation must be sent to both carriers immediately.
Dashcam footage from both commercial vehicles and any nearby vehicles or infrastructure cameras. If either truck had a forward-facing or inward-facing dashcam, the footage is the single most powerful piece of evidence in the case — a visual record of the underride sequence, the lane positioning, and the causation. Dashcam loops overwrite — typically within 7 to 30 days. City and traffic cameras in the S.M. Wright Freeway corridor may cycle in 7 to 14 days. If we do not request that footage before the cycle, it is gone forever.
Both trailers and their underride guards. The physical trailers — with their rear-impact guards, their contact damage, their paint transfers, their gouge marks — are the central physical evidence in the case. They must be inspected for compliance with 49 CFR 393.86, for guard integrity, for prior damage, and for whether the guard failed or was absent. Carriers may repair, scrap, or release vehicles from impound. Emergency impoundment and an inspection order may be required. If the carrier repairs or disposes of the trailer before inspection, the evidence is destroyed — and the law provides remedies for that destruction, including an adverse-inference instruction that allows the jury to assume the lost evidence was as bad as the plaintiff says it was.
Driver qualification files, drug and alcohol test results, and driving records for both commercial drivers. These files establish whether each driver was qualified, whether they had prior violations, and whether post-accident drug and alcohol testing was performed within the required windows (8 hours for alcohol, 32 hours for drugs). If the testing was not done, that failure is itself a violation — and it is a violation that suggests the carrier had reason to fear the results.
Texas Peace Officer’s Crash Report (CR-3) and supplemental law-enforcement reports. The official crash report will contain the investigating officer’s reconstruction, witness statements, and a preliminary fault assessment. The initial report is typically available in 7 to 14 days. Reconstruction supplements may take longer. This report is the starting point — but it is not the ending point. Our own reconstruction expert will build the independent analysis that the case actually turns on.
Scene evidence — skid marks, gouge marks, debris field, and underride guard contact evidence. The physical scene tells the story of the underride angle, the speed, and the sequence. Skid marks show braking. Gouge marks in the pavement show where the trailer’s underside contacted the road after the passenger vehicle was driven beneath it. The debris field shows the direction and energy of the impact. This evidence is remediated within days — weather, traffic, and road crews erase it. If the scene is not documented by a qualified reconstructionist in the first 24 to 48 hours, it is lost.
Maintenance and inspection records for both commercial vehicles. These records establish whether each carrier maintained its vehicle in compliance with 49 CFR Part 396. Prior brake issues, tire problems, or guard damage would be documented here — if the records are honest. Records can be altered or purged. The preservation letter demands that they be maintained in their current form.
The Insurance Adjuster’s Playbook: What They Will Try and How to Counter Each Move
Lupe Peña spent years inside a national insurance-defense firm. He sat in the rooms where claims like yours are priced, where the adjusters run the valuation software, where the reserve is set in the first 48 hours before the real injuries are diagnosed. He knows the plays because he used to run them. Here is what the insurance companies will do — and here is how each play is countered.
Play 1: The friendly “just checking in” call. Within days, someone will call you. They will sound warm and concerned. They will say they just want to “check on you” and ask you to “just tell us what happened.” The call is recorded. Everything you say will be transcribed and used to build a comparative-fault argument. If you say “I think I was going a little fast” or “I didn’t see the truck until the last second,” those words will be quoted back to you at trial as your own admission of fault. The counter: do not give a recorded statement. You are not required to. Say nothing to the adjuster except “I am represented by counsel” — or, if you have not yet hired counsel, “I am not ready to give a statement.” That is your right. Exercise it.
Play 2: The fast settlement check with a release attached. A check may arrive quickly — sometimes within the first two weeks. It will come with a release document that, once signed, extinguishes every claim you have against the carrier, forever, regardless of what the medical records eventually show. The check is designed to arrive before the MRI results, before the neuropsychological evaluation, before the full extent of the brain injury or spinal damage is known. The counter: never sign anything from an insurance company without having it reviewed by an attorney. A release is a legal document that ends your case. The amount on that check is a fraction of what the case is worth — and the carrier knows it.
Play 3: The “you were partly at fault” argument. Texas follows a modified comparative negligence rule — your own share of fault reduces your recovery, and if you are more than 50 percent at fault, you are barred from recovery entirely. The adjuster’s job is to pin percentage points on the passenger-vehicle driver: speed, lane positioning, following distance, inattention. Every point is money. If they can push the allocation to 51 percent, the case is worth zero. The counter: fault allocation is established through expert reconstruction, not through the adjuster’s assumptions. The EDR data, the ELD data, the dashcam footage, the scene evidence — all of it goes to proving what actually happened, not what the carrier wants a jury to believe happened. We do not concede fault. We prove it.
Play 4: The independent medical examination (IME) with the insurer’s chosen doctor. The carrier will demand that you be examined by a doctor they select. That doctor is not neutral — they are paid by the insurance company, and their reports are designed to minimize your injuries. The counter: we make sure you are receiving treatment from your own doctors, that your medical records are complete and accurate, and that any IME is conducted under proper conditions with your counsel involved.
Play 5: Social-media surveillance. The carrier’s investigators will monitor your social media. They will look for posts that suggest you are active, happy, or functioning normally — and they will use those posts to argue that your injuries are not as severe as you claim. The counter: set your accounts to private. Do not post about the crash, your injuries, your recovery, or your activities. Do not discuss the case online. Assume everything you post will be printed and handed to a jury.
Play 6: The “we need more time” delay aimed at the statute of limitations. Texas wrongful-death actions carry a two-year statute of limitations. The carrier may string out negotiations, request additional documentation, and make slow progress — all designed to run the clock until the deadline passes. Once the statute runs, the case is dead. The counter: we track every deadline. We file before the statute runs. The carrier does not get to decide when your time is up.
The Medicine: What Roof-Shearing Does to the Human Body
We are going to talk about the injuries honestly, because you need to know what you are dealing with — and because the medical reality is what drives the value of the case.
When a passenger vehicle’s roof is torn off in an underride crash, the injury mechanism is direct trauma to the head, neck, and upper torso from the trailer’s underside structure. The trailer floor, cross-members, and landing gear contact the occupant’s head and upper body at highway speed. The injuries this produces fall into several categories:
Traumatic brain injury (TBI). The force of the trailer striking the head can produce a range of brain injuries — from concussion to diffuse axonal injury (the tearing of the brain’s white-matter tracts from rotational acceleration) to skull fracture with direct brain contusion. A “mild” traumatic brain injury can come with a perfectly normal CT scan — that is the standard presentation, not the exception. The injury is proven through neuropsychological testing, advanced imaging (such as diffusion tensor imaging or susceptibility-weighted imaging), and the testimony of people who knew the person before the crash. You may see the changes across the dinner table before any scan sees them: the headaches, the lost words, the short fuse, the inability to follow a conversation, the personality changes that destroy relationships and careers. Roughly one in seven TBI patients still has symptoms three months later. Many never fully recover.
Cervical spine fracture and spinal cord injury. The forces involved in roof shearing can fracture the cervical vertebrae and, in catastrophic cases, sever the spinal cord. A complete spinal cord injury at the cervical level means paralysis below the level of the lesion — potentially quadriplegia. The emergency response, the surgical intervention, the ICU stay, the rehabilitation, and the lifelong care needs are staggering in cost and human terms.
Cranial-cervical trauma at decapitation-level severity. In the most severe underride crashes, the mechanism produces injuries that are not survivable. The roof is sheared at the level of the occupant’s head and neck. If the victim died, the injury mechanism is central to the wrongful-death and survival claims — and the conscious pain and suffering between injury and death, however brief, is a recoverable damage under Texas survival law.
Facial and cranial degloving injuries. Survivors of severe underride crashes often suffer catastrophic facial injuries — fractures of the maxillofacial skeleton, degloving of the scalp and face, eye injuries including enucleation. These injuries require reconstructive surgery, produce permanent disfigurement, and carry enormous psychological impact.
If the victim survived, the medical cascade includes emergency medical transport, trauma-center resuscitation, neurosurgical intervention, prolonged ICU stay, rehabilitation, and lifelong medical needs. If the victim was taken to a Dallas trauma center, the medical records from the first hours are the foundation of the injury proof — and they must be obtained and preserved.
What a Case Like This Is Worth: The Damages Architecture
We are going to talk about money because money is what the law provides, and because the amount of money at stake is what determines whether the carrier takes your case seriously or tries to make it disappear.
Given the roof-shearing underride mechanism involving two commercial carriers, the case value range runs from approximately $1,500,000 on the low end to $25,000,000 or more on the high end. Here is how that range is built.
Economic damages are the measurable costs. They include past and future medical expenses — emergency transport, trauma-center resuscitation, surgery, ICU, hospitalization, rehabilitation, medications, assistive devices, home modifications, and lifelong care. They include lost earning capacity — the income the victim would have earned over their working life, reduced to present value by a forensic economist. They include loss of household services — the value of the work the victim performed in the home that now must be paid for. For a catastrophic brain injury or spinal cord injury, the life-care plan alone — the projected cost of future medical care over the victim’s expected lifespan — can run into the millions.
Non-economic damages are the human losses. Physical pain and suffering. Mental anguish. Disfigurement. Loss of enjoyment of life. The life the victim no longer gets to live. The relationship the spouse no longer has. The parent the children no longer have. These damages are not capped in Texas for cases involving commercial defendants. There is no statutory ceiling on what a jury can award for pain and suffering, mental anguish, or loss of companionship in a case against a commercial motor carrier.
Wrongful-death damages — if the victim died — are recoverable by the statutory beneficiaries: spouse, children, and parents. These include loss of financial support, loss of companionship and society, mental anguish, and loss of inheritance. The Texas Wrongful Death Act governs these claims, and the filing deadline is two years from the date of death.
Survival damages allow recovery for the decedent’s conscious pain and suffering between injury and death, plus the medical expenses incurred before death. In an underride crash, the survival window may be brief — but the suffering during that window is real and compensable.
Punitive damages are available in Texas upon a showing of gross negligence — conduct involving an extreme degree of risk of which the actor has actual, subjective awareness but proceeds with conscious indifference. If a carrier knew its underride guard was damaged, knew its driver was fatigued or unqualified, or knew its vehicle was being operated unsafely and did nothing, that is the predicate for punitive damages. Texas caps punitive damages under a statutory formula — generally the greater of $200,000 or two times economic damages plus non-economic damages up to $750,000 — but the cap does not apply to the economic and non-economic damages themselves.
The low end of the range reflects comparative-fault exposure — if the passenger vehicle’s speed or lane positioning contributed to the underride — plus the possibility that one carrier’s liability is limited or contested. The high end reflects a fatal outcome or permanent catastrophic brain injury, clear FMCSA violations, two deep-pocket commercial defendants, and gross-negligence/punitive exposure. Collectibility is strong: the federal minimum financial-responsibility requirement ensures at least $750,000 per carrier, and most interstate carriers carry substantially more, stacked in layers that can be pursued sequentially.
Past results depend on the facts of each case and do not guarantee future outcomes. We cannot promise you a number. We can tell you that the firm has recovered over $50 million in aggregate, including a $5 million-plus brain-injury settlement, a $3.8 million-plus amputation settlement, and a $2.5 million-plus truck-crash recovery. Those are not predictions for your case. They are proof that we know how to build and value cases at this level.
Texas Law: Comparative Fault, Wrongful Death, and the Stowers Doctrine
Texas follows a modified comparative negligence regime — the 51 percent bar rule. Your recovery is reduced by your percentage of fault, and if you are more than 50 percent at fault, you are barred from recovery entirely. This is why the adjuster works so hard to pin fault on the passenger-vehicle driver. Every percentage point they can assign to the car is money off the verdict. But comparative fault is not decided by the adjuster — it is decided by a jury, based on the evidence. And the evidence in this case — the EDR data, the ELD data, the dashcam footage, the reconstruction analysis — is what will establish what actually happened on the S.M. Wright Freeway.
Texas has no statutory cap on compensatory damages in personal-injury or wrongful-death cases involving commercial defendants. A jury can award the full measure of economic and non-economic damages the evidence supports. This is one of Texas’s strongest advantages for plaintiffs in commercial-vehicle cases — and the insurance company’s lawyers know it.
The Texas Wrongful Death Act governs claims brought by the surviving spouse, children, and parents of a person killed by another’s negligence. The statute of limitations is two years from the date of death. Survival actions, governed by the same statutory framework, allow recovery for the decedent’s conscious pain and suffering and medical expenses incurred before death.
The Stowers doctrine is a Texas common-law rule that creates a duty for insurers to accept reasonable settlement demands within policy limits. If the insurer refuses a properly crafted Stowers demand that is within policy limits and gives the insurer a reasonable time to accept — and a subsequent verdict exceeds the policy limits — the insurer faces bad-faith exposure for the excess. This is a powerful leverage tool. It means that in a case with catastrophic damages and clear liability, the carrier’s own insurer bears the risk of refusing to settle. The dual-carrier structure in this case creates cross-claim and apportionment dynamics that can be used in settlement negotiations by treating each carrier’s excess exposure independently.
The First 72 Hours: What to Do Now
Hour 1 through 24: Medical first. If the victim is hospitalized, your first job is to be with them and to make sure the medical team has the full picture. If you are the one injured, your first job is to get every symptom documented — even symptoms that seem minor. Brain injuries can have delayed presentation. A person who seems “fine” at the scene may deteriorate over hours. Do not refuse medical evaluation. Do not say “I’m okay” to anyone — not to the EMT, not to the police officer, not to the adjuster who calls. Symptoms lie. The adrenaline of a crash masks pain. The MRI does not.
Hours 24 through 48: Evidence preservation. This is where the case is won or lost. The preservation letters must go out to both carriers — demanding that they preserve the ELD data, the EDR data, the dashcam footage, the driver qualification files, the maintenance records, and the physical trailers with their underride guards. The scene must be documented by a qualified reconstructionist before weather and traffic erase the evidence. The vehicles must be secured in impound — not released to the carriers, not repaired, not scrapped. If you have not yet hired counsel, do not speak to the insurance company, do not sign anything, and do not allow the vehicles to be moved or released.
Hours 48 through 72: The legal machinery begins. If the victim died, a personal representative must be appointed — the person Texas law authorizes to bring the wrongful-death claim on behalf of the family. We handle that appointment. The crash report is being completed by the investigating agency. The initial medical records are being generated. The insurance adjusters are already working — setting reserves, evaluating liability, planning their comparative-fault argument. You need someone working for you at the same speed.
What not to do:
– Do not give a recorded statement to any insurance adjuster.
– Do not sign any document from any insurance company.
– Do not post about the crash, your injuries, or your activities on social media.
– Do not discuss fault with anyone — not the police, not the adjuster, not friends, not online.
– Do not allow the vehicles or trailers to be released, repaired, or scrapped.
– Do not wait. The evidence clock is running.
The Proof Story: How a Case Like This Is Actually Built
Here is how a case like this is won — not in the abstract, but step by step.
Week one: The preservation letters go out. Simultaneous demands to both carriers, freezing the ELD data, the EDR data, the dashcam footage, the driver qualification files, the maintenance and inspection records, and the physical trailers. The scene is documented by a board-certified accident reconstructionist. The vehicles are secured. The medical records are being generated and collected.
Weeks two through four: The downloads. The EDR data from both tractors and the passenger vehicle is downloaded before it can be overwritten. The ELD data is pulled. The dashcam footage is requested and obtained. The Texas Peace Officer’s Crash Report (CR-3) is obtained and reviewed. The driver qualification files and post-accident drug and alcohol test results are demanded.
Months one through three: The experts. A board-certified accident reconstructionist builds the independent analysis of the dual underride sequence — the angle, the speed, the braking, the lane positioning, the sequence of impacts. A forensic biomechanist opines on the injury mechanism — how the roof-shearing produced the specific injuries. A trucking safety expert evaluates both drivers’ compliance with FMCSA regulations and industry standards. If the underride guard failed, a products-liability expert inspects the guard and opines on design defect.
Months three through six: Discovery and depositions. The records come out in discovery. The drivers are deposed — under oath, about their maneuvers, their hours, their training, their compliance. The safety directors are deposed — about the carrier’s hiring, training, supervision, and maintenance practices. The corporate representatives are deposed — about the company’s safety culture, its SMS scores, its history of violations.
The number is built from all of it. The life-care planner builds the cost stream of future medical care. The forensic economist reduces it to present value. The pain and suffering, the mental anguish, the loss of companionship, the loss of the life the victim no longer gets to live — all of it is documented, quantified, and presented. The Stowers demand is filed. If the carrier refuses and the verdict exceeds policy limits, the carrier’s insurer faces the excess. That is leverage. That is how the case is won.
Frequently Asked Questions
What is an underride crash and why is it so dangerous?
An underride crash occurs when a passenger vehicle slides underneath the trailer of a commercial truck, bypassing the car’s crumple zones, airbags, and structural safety cage. The trailer’s underside contacts the vehicle at windshield and roof height — shearing off the roof and directly striking the occupants’ heads and upper bodies. It is one of the most lethal crash types in motor-vehicle reconstruction because the safety systems that protect occupants in normal collisions never engage.
Can I sue if my family member was killed in an underride crash in Dallas?
Yes. Under the Texas Wrongful Death Act, the surviving spouse, children, and parents of a person killed by another’s negligence may bring a wrongful-death claim. The claim must be filed within two years of the date of death. A survival action may also be brought for the decedent’s conscious pain and suffering and medical expenses incurred before death. If two commercial carriers were involved, both may be named as defendants.
How long do I have to file a wrongful-death lawsuit in Texas?
Texas wrongful-death actions carry a two-year statute of limitations from the date of death. This is a hard deadline — if the lawsuit is not filed within two years, the claim is barred. There may be limited exceptions or tolling provisions, but you should never assume an exception applies without consulting an attorney. The evidence clock is even shorter: EDR data can overwrite in 30 days, dashcam footage in 7 to 14 days, and scene evidence in days.
What if the insurance company says the car driver was partly at fault?
Texas follows a modified comparative negligence rule — your recovery is reduced by your percentage of fault, and if you are more than 50 percent at fault, you are barred. The adjuster will try to assign fault to the passenger-vehicle driver for speed, lane positioning, or following distance. But fault allocation is established through expert reconstruction — EDR data, ELD data, dashcam footage, and scene evidence — not through the adjuster’s assumptions. We do not concede fault. We prove what happened.
How much is a Dallas underride crash case worth?
The value depends on the confirmed injuries, the victim’s age and earning capacity, the allocation of fault between the two carriers, and whether gross negligence can be established. Given the roof-shearing mechanism with two commercial carriers, the range runs from approximately $1.5 million on the low end to $25 million or more on the high end. The high end reflects a fatal outcome or permanent catastrophic brain injury, clear FMCSA violations, two deep-pocket defendants, and punitive exposure. Past results depend on the facts of each case and do not guarantee future outcomes.
Do both trucking companies have insurance?
Yes. Federal law requires interstate general-freight carriers to carry a minimum of $750,000 in financial responsibility, per 49 CFR 387.9. Most interstate carriers carry substantially more — typically $1 million in primary coverage plus excess and umbrella layers. With two carriers involved, the coverage towers stack. The MCS-90 endorsement, required under 49 CFR 387.15, ensures that the motor carrier’s insurance provides continuous coverage for public liability regardless of certain policy exclusions.
What should I do if the insurance adjuster calls me?
Do not give a recorded statement. You are not required to. Say: “I am represented by counsel” — or, if you have not yet hired counsel, “I am not ready to give a statement.” Do not discuss the crash, your injuries, or what you remember. Do not sign anything. Do not accept any check. Everything you say will be transcribed and used to build a comparative-fault argument against you. The adjuster is not your friend — they are a professional doing a job, and that job is to minimize the carrier’s payout.
Can I still recover if the underride guard was present but failed?
Yes. A rear-impact guard that meets the minimum federal standard under 49 CFR 393.86 can still fail in a real-world crash — particularly at higher impact speeds or at overlap angles where the passenger vehicle contacts the guard off-center. If the guard failed to prevent underride, a products-liability claim against the trailer manufacturer for design defect or manufacturing defect is viable. The industry has documented knowledge that standard guards are inadequate under certain real-world conditions. Physical inspection of the guard is essential — and it must happen before the carrier repairs or disposes of the trailer.
What is the Stowers doctrine and how does it help my case?
The Stowers doctrine is a Texas common-law rule that creates a duty for insurers to accept reasonable settlement demands within policy limits. If the insurer refuses a properly crafted demand within policy limits and gives the insurer a reasonable time to accept — and a subsequent verdict exceeds the policy limits — the insurer faces bad-faith exposure for the excess. In a case with catastrophic damages and clear liability, this means the carrier’s own insurer bears the risk of refusing to settle. With two carriers, each carrier’s excess exposure can be treated independently, creating powerful settlement leverage.
How quickly do I need to hire a lawyer after an underride crash?
Immediately. The evidence clock is the reason. EDR data can overwrite in 30 days. Dashcam footage can cycle in 7 to 14 days. Scene evidence — skid marks, gouge marks, debris fields — is erased by weather and traffic within days. The physical trailers can be repaired, scrapped, or released from impound. The preservation letters that freeze this evidence must go out the day you call — not next week, not after the funeral, not after the insurance company makes its first offer. Every day that passes is a day the carriers can legally destroy evidence that decides your case.
Who We Are and Why This Matters
Ralph Manginello has spent 27-plus years in courtrooms, including federal court — the U.S. District Court, Southern District of Texas. He was a journalist before he was a lawyer, which means he knows how to find the story the evidence tells and how to present it to a jury. He is a member of the Texas Trial Lawyers Association and the Houston Bar Association. He is the lead counsel in the active $10 million-plus Bermudez v. Pi Kappa Phi / University of Houston hazing lawsuit. He does not lose cases because he does not accept cases he cannot win — and the cases he takes, he fights.
Lupe Peña is a former insurance-defense attorney. He spent years at a national defense firm — the rooms where adjusters and their software decided how to deny, delay, and devalue people exactly like you. He knows how the reserve is set in the first 48 hours before the real injuries are diagnosed. He knows how the recorded-statement call is engineered. He knows how the claim is fed into valuation software that discounts pain it cannot see. He knows all of this because he used to do it — and now he uses that knowledge for injured clients. Lupe is fluent in Spanish. He conducts full client consultations in Spanish without an interpreter. If your family prays in Spanish, we speak your language.
The firm has recovered over $50 million in aggregate, including a $5 million-plus brain-injury settlement, a $3.8 million-plus amputation settlement, a $2.5 million-plus truck-crash recovery, and a $2 million-plus maritime back-injury settlement. These are not predictions for your case. Past results depend on the facts of each case and do not guarantee future outcomes. But they are proof that we know how to build, value, and resolve cases at the level your family needs.
We work on contingency. That means we do not get paid unless we win your case. The fee is 33.33 percent if the case resolves before trial and 40 percent if it goes to trial. The consultation is free. The call is free. The preservation letter is sent the day you call. We have 24/7 live staff — not an answering service, not a robot, not a call center. A human being who works for this firm answers the phone at 2 a.m. because that is when people in crisis call.
