Houston 18-Wheeler Accident Lawyer: Strategic Advocacy for Commercial Vehicle Collisions
Updated: Sep 3
When a commercial vehicle weighing up to 80,000 pounds collides with a passenger car on the 610 Loop or I-45, the results are rarely minor. These cases sit at the intersection of federal safety regulation, large insurance policies, and life-altering injury. Handling one takes a Houston 18-wheeler accident lawyer who knows the federal regulations, knows what Texas law changed in 2021, and can move fast enough to preserve the evidence before it is gone.
The Demerson Firm, PLLC keeps a disciplined caseload so that truck cases get the work they require — preservation letters out immediately, ELD and ECM data secured, the carrier's own compliance records pulled apart. This article covers what actually governs these claims in Texas, including the statute that reshaped them.
Key Takeaways
Multiple Defendants: Commercial collisions frequently involve the driver, the motor carrier, a broker, a shipper or loader, and maintenance contractors.
Regulatory Complexity: These cases turn on the Federal Motor Carrier Safety Regulations and on electronic data — ELD logs, ECM downloads, GPS.
Texas House Bill 19 Changed the Rules: Since September 1, 2021, Chapter 72 of the Civil Practice and Remedies Code lets a trucking defendant split the trial in two and limits what a jury hears in the first phase. Any truck case filed in Texas now runs through it.
Evidence Has a Shelf Life: Driver logs, maintenance records, and electronic logging device data must be preserved early. Carriers are only required to retain records of duty status for six months.
Comparative Fault Cuts Deep: A share of blame reduces your recovery proportionally, and a share greater than 50% eliminates it. Defense counsel knows this and works toward it from day one.
The Reality of 18-Wheeler Accidents in Houston
A Houston 18-wheeler accident lawyer works the freight corridors of Harris County — the Port of Houston traffic, I-10, I-45, US-59, the 610 Loop. Driver fatigue, deferred maintenance, and scheduling pressure produce collisions here that are rarely survivable at highway speed without serious injury.
What makes these cases different from an ordinary car wreck is not the size of the vehicle. It is that the defendant is a regulated business with a compliance department, a rapid response team, and counsel on retainer who may be at the scene before the vehicles are towed. The carrier begins building its defense immediately. A claimant who waits several weeks to talk to a lawyer is already behind.
Quick Facts: The Rules That Govern a Texas Truck Case
Bifurcation is on the defendant's motion: Under Tex. Civ. Prac. & Rem. Code § 72.052, the court must bifurcate if a defendant timely moves — by the later of 120 days after its original answer or 30 days after a pleading adding a claim. It is not automatic.
Minimum insurance: Under 49 C.F.R. § 387.9, an interstate for-hire carrier hauling non-hazardous property in a vehicle rated over 10,000 pounds must carry at least $750,000. Hazmat minimums are higher.
Six months: How long a carrier must retain a driver's records of duty status. Miss that window without a preservation letter and the logs may be gone lawfully.
Two years: The limitations period under Tex. Civ. Prac. & Rem. Code § 16.003(a). If a governmental unit is involved, a written notice deadline of six months or less applies long before that.
The Federal Layer: FMCSA Regulations
Federal regulation governs almost every operational aspect of a commercial carrier — driver qualification, hours of service, drug and alcohol testing, inspection and maintenance, and the electronic data that records how the vehicle was actually driven. Those rules are also where a case is won, because a violation is documented, objective, and hard to talk around.
Hours-of-service rules exist to prevent fatigue, and logbook manipulation remains a recurring problem. Electronic logging devices made it harder but not impossible. We cross-reference ELD records against fuel receipts, toll data, GPS pings, dispatch records, and delivery timestamps, because those independent sources are what expose a log that does not match reality.
Texas also applies modified comparative fault. Under Tex. Civ. Prac. & Rem. Code § 33.001, a share of responsibility at or below 50% reduces your recovery proportionally — it does not eliminate it. Only a share greater than 50% bars recovery entirely. That distinction matters, because carriers and their insurers work hard to attach a percentage to the injured driver, and a percentage is not the same thing as a defense.
House Bill 19 and Chapter 72: The Texas Rule That Reshaped Truck Cases
In 2021 the Texas Legislature passed House Bill 19, which created Subchapter B of Chapter 72 of the Civil Practice and Remedies Code. It applies to commercial motor vehicle collision cases and took effect September 1, 2021. Any Texas lawyer handling a truck case now works inside it, and any article about Texas truck accidents that does not mention it is out of date.
The core mechanism is bifurcation. Under § 72.052, a defendant may move to split the trial in two, and if the motion is timely the court shall grant it. Phase one determines liability and the amount of compensatory damages. Phase two determines exemplary damages. Note what that means: bifurcation is not automatic, and it does not happen unless a defendant asks for it within the statutory window.
What matters most to an injured client is what the jury is permitted to hear in phase one. Under § 72.054, if the employer stipulates that the driver was its employee acting within the scope of employment, the claimant generally may not present a negligent entrustment theory in phase one — the company's liability rests on respondeat superior instead. That was the point of the bill: to keep a company's hiring history away from the jury deciding compensatory damages.
But the exceptions are substantial, and they are where a well-built truck case lives. Section 72.054(c) lists evidence that remains admissible in phase one against an FMCSA-regulated carrier, including whether the driver:
was properly licensed, or was disqualified under 49 C.F.R. § 383.51, § 383.52, or § 391.15;
was subject to an out-of-service order, or was medically certified as physically qualified under § 391.41;
was driving in violation of the hours-of-service rules in § 395.3 or § 395.5;
was texting or using a handheld phone in violation of § 392.80 or § 392.82; or
refused a required controlled-substance test in the two years before the collision — and whether the carrier itself ran the background investigations required by § 391.23(a).
Section 72.053 governs regulatory-violation evidence generally: it comes in during phase one only if the violation tends to prove proximate cause and the regulation is specific and actually governs that defendant. Two further provisions are worth knowing. Section 72.054(f) preserves claims that do not depend on proving the driver negligent — negligent maintenance, for example — so those stay in phase one. And § 72.055 provides that photographs and video of the vehicles are presumed admissible without expert testimony, which matters when a carrier argues that a vehicle does not look damaged enough to have injured anyone.
The practical lesson is that Chapter 72 rewards early, documentary case-building. The evidence that survives into phase one is regulatory and record-based, and most of it sits in files the carrier controls and is only obligated to keep for a limited time.
Why Caseload Size Matters in a Truck Case
A commercial vehicle case takes work that a routine claim does not: preservation letters within days, a request for the carrier's driver qualification file, an ECM download before the tractor is repaired or sold, an accident reconstruction expert, and a life care planner where the injuries are permanent. When you interview a Houston 18-wheeler accident lawyer, ask how many cases the handling attorney carries, who will do that work, and what has already been sent to preserve evidence. Those answers are more informative than any slogan.
We build every truck case as though a Harris County jury will hear it, because Chapter 72 makes the early record decisive and because a carrier's evaluation of a claim changes when the file looks trial-ready. That means the evidence gets developed first and the negotiation happens second.
Identifying Liability and Calculating Damages
Liability in a commercial case rarely stops at the driver. A Houston 18-wheeler accident lawyer looks at the motor carrier, the broker, the shipper or loading crew, maintenance vendors, and parts manufacturers, then works out which theories survive Chapter 72's phase-one restrictions.
The carrier is typically vicariously liable for the driver under respondeat superior. Independent theories against the company still matter, and some of them survive a stipulation:
Negligent Hiring and Entrustment: Putting a driver with a disqualifying record behind the wheel. Under § 72.054 this is limited in phase one if the employer stipulates — but the specific items in § 72.054(c) still come in.
Negligent Maintenance: Failing to inspect or repair brakes, tires, or lighting. Because this does not require proving the driver negligent, § 72.054(f) preserves it for phase one.
Improper Loading: Overloaded or unsecured cargo that shifts in transit, which can implicate the shipper or loading facility as a separate defendant.
On damages, the hospital bill to date is the beginning, not the measure. Where an injury is permanent — a brain injury, a spinal cord injury, an amputation — the real question is the cost of the decades that follow: future surgeries, attendant care, adaptive equipment, home modification, and lost earning capacity. We work with life care planners and economists to establish those figures on evidence rather than estimate, because a number a jury or an adjuster can verify is the only kind worth presenting.
Partnering with The Demerson Firm, PLLC
Engaging a Houston 18-wheeler accident lawyer early is what makes the difference in a commercial case, because the most valuable evidence is electronic, held by the defendant, and subject to lawful destruction on a schedule.
We send preservation letters immediately, pursue the driver qualification file and the maintenance history, secure the ECM data before the tractor moves through repair or salvage, and structure the case around what Chapter 72 will actually let a jury see. Whether the collision happened near the Port of Houston or out on I-10, that is the work.
If you are ready to talk, we offer a comprehensive injury case review to go through the specifics of your collision and what needs to happen first.
Frequently Asked Questions
1. What is a Houston 18-wheeler accident case worth?
There is no useful average, and anyone quoting you a range before reviewing your file is guessing. What drives value is the severity and permanence of the injury, the strength of the liability evidence, the insurance actually available, and how much fault the defense can attach to you. Commercial policies are generally larger than personal auto policies — 49 C.F.R. § 387.9 sets a $750,000 federal minimum for most interstate freight carriers — but a large policy limit is a ceiling, not a valuation.
2. How long do I have to file a truck accident lawsuit in Texas?
Generally two years from the date of the crash under Tex. Civ. Prac. & Rem. Code § 16.003(a). But limitations is the outside boundary, not the working deadline. Carriers are only required to retain records of duty status for six months, and if a governmental unit is involved a written notice deadline of six months or less applies. Waiting is how good cases lose their proof.
3. Who is liable if the truck driver was an independent contractor?
The "independent contractor" label is far less protective than carriers suggest. The definition of "employee" in 49 C.F.R. § 390.5 expressly includes an independent contractor while operating a commercial motor vehicle, which substantially undercuts the defense in a federally regulated case. Texas law reaches the same territory from another direction — under Tex. Civ. Prac. & Rem. Code § 72.051(6), "employee" includes any agent or person for whom an employer may be liable under respondeat superior.
4. What is the most important evidence in a truck accident case?
Usually the electronic record. The Electronic Control Module (ECM) — the "black box" — captures speed, throttle, and brake application in the seconds before impact, and the ELD records the driver's hours. Together they can establish speeding, failure to brake, or a fatigued driver well past the hours-of-service limits. All of it can be lost if the tractor is repaired or sold before anyone demands preservation.
5. Can I still recover if I was 20% at fault?
Yes. Under Tex. Civ. Prac. & Rem. Code § 33.001, you recover as long as your share of responsibility is not greater than 50%. Your award is reduced by your percentage — 20% responsibility on a $100,000 award leaves $80,000. Only a share above 50% bars recovery.
6. Why not take the first offer from the trucking company?
An early offer usually arrives before anyone knows how the injuries will resolve, and a signed release ends the claim permanently — including the future surgery nobody has scheduled yet. It also typically arrives before your lawyer has seen the ELD data, the driver qualification file, or the maintenance history, which is to say before anyone knows what the case is actually worth.
7. How long does a commercial truck case take?
Often 12 to 24 months, and longer if the case is tried. Part of that time is necessary: a serious injury needs to reach maximum medical improvement before anyone can value it honestly. Chapter 72 bifurcation can also add structure and time to a trial setting.
8. Do you handle accidents on I-45 and the 610 Loop?
Yes — including I-45, I-10, US-59, and the 610 Loop, and the Port of Houston freight corridors. We handle commercial vehicle matters in Harris, Fort Bend, Montgomery, Brazoria, and Galveston Counties.
