Proving Fault in Irving Truck Accident Cases

Written by Geoffrey Dashner. Read more about the author.

Truck crashes on I-635, SH-183, and the surface streets running through Irving are not like ordinary car accidents. The vehicles weigh up to 80,000 pounds, the regulatory framework is dense, and the liable parties can number four or five before you even finish your initial investigation. I’ve handled these cases for years at Dashner Law Firm | Irving Injury & Accident Attorney, and the single biggest difference between a case that settles well and one that falls apart is the evidence gathered in the first 72 hours. This post walks through exactly how fault is proven, who tends to be liable, and what you should look for if you’re choosing a lawyer to handle your claim.

How Attorneys Prove Fault in Truck Accident Cases in Irving?

Proving fault in a commercial truck accident is an evidence-intensive process. It is not enough to show that the truck hit your vehicle. You need to establish why it happened, who bears legal responsibility, and how their failure caused your specific injuries and losses. Here is how that gets done.

The Electronic Logging Device (ELD) and black box data. Federal regulations under 49 C.F.R. Part 395 require most commercial carriers to use ELDs that record hours of service in real time. Hours-of-service violations — a driver who has been behind the wheel too long — are one of the most common contributing factors in serious crashes. The truck’s Engine Control Module (ECM) also records speed, brake application, throttle position, and gear changes in the seconds before impact. I subpoena this data immediately, because carriers are only required to preserve it for six months, and some will argue shorter retention windows if you wait.

Driver qualification and personnel files. Under FMCSA regulations, carriers must maintain driver qualification files showing CDL status, medical certification, prior driving history, and drug and alcohol testing records. A driver with a suspended CDL, a failed pre-employment drug screen, or a history of prior violations who is still behind the wheel — that is evidence of negligent hiring or negligent retention on the part of the carrier.

Maintenance and inspection records. The FMCSA requires annual inspections and systematic preventive maintenance programs. When a brake failure or tire blowout contributes to a crash, I pull the maintenance logs for that specific unit. If a defect was noted and not repaired, that creates a clear chain from the carrier’s conduct to the collision.

The accident scene itself. Skid marks, gouge marks, final rest positions, debris fields, and traffic control device positions are all documented by law enforcement, but law enforcement reports are a starting point, not the finish line. I work with accident reconstruction specialists who use photogrammetry and physical evidence to calculate speed and impact angles independently. The Irving Police Department and TxDOT crash records are subpoenaed as well.

Witness statements and dashcam footage. Irving sits at a major commercial corridor intersection. There are fleet vehicles, rideshare drivers, and delivery trucks on these roads constantly, and a surprising number of them have forward-facing dashcams. Canvassing for that footage within the first 48 hours — before it overwrites — has changed the outcome of cases I would otherwise have had a harder time proving.

Toxicology. If law enforcement did not conduct a post-crash drug and alcohol screen, that is a problem. If they did, those results become part of the evidentiary record. Amphetamine and stimulant use among long-haul drivers is a real issue documented in CDC research on commercial driver fatigue and substance use. A positive screen shifts the case significantly.

Texas follows a modified comparative fault rule under Texas Civil Practice and Remedies Code § 33.001. That means your recovery is reduced proportionally if you are found partially at fault, and you recover nothing if your share exceeds 50%. Defense attorneys for carriers will push hard to assign fault to the injured driver. Solid physical evidence gathered early is the primary defense against that strategy.

How Personal Injury Lawyers Help with Trucking Accident Cases?

The paperwork alone in a commercial truck accident is substantial — FMCSA crash reports, state police reports, carrier insurance declarations, and often multiple sets of medical records. But what a good Texas truck accident attorney actually does goes well beyond organizing documents.

In my experience, the most valuable early intervention is sending a litigation hold letter to the carrier. This letter puts them on formal legal notice to preserve all records — ELD data, ECM data, dispatch communications, GPS logs, and driver personnel files. Carriers that destroy evidence after receiving a litigation hold letter face spoliation sanctions in court. That threat alone changes how the defense approaches a case.

Beyond evidence preservation, lawyers manage the claim against multiple insurance policies simultaneously. A single truck accident can involve the carrier’s primary liability policy (which federally must be at least $750,000 for most loads, and $5 million for hazardous materials under 49 C.F.R. Part 387), a separate cargo policy, and potentially a shipper’s policy if improper loading contributed to the crash. Identifying all applicable coverage and pursuing it in the right sequence matters enormously for the injured person’s eventual recovery.

Lawyers also handle the medical-legal connection. Trucking defense teams routinely argue that injuries are pre-existing or unrelated to the accident. A personal injury attorney coordinates with treating physicians to get clear causation opinions in the record, which protects the claim at both the settlement and trial stages.

Finally — and this matters — experienced truck accident lawyers know when to file suit and when to hold. Carriers sometimes make early settlement offers that look reasonable but are far below what a jury would award for serious injuries. I have seen clients receive offers within 30 days of a crash that were a fraction of what we ultimately recovered after filing suit. If you do not have a lawyer who has actually tried truck accident cases to verdict, you are negotiating with people who know you are unlikely to go all the way.

How Attorneys Identify Liable Parties in a Trucking Accident?

This is where truck cases diverge most sharply from car accident cases. In a standard two-car crash, there is usually one driver who is at fault. In a commercial trucking crash, the potentially liable parties can include the driver, the motor carrier, the truck’s owner (which may be different from the carrier), the cargo shipper or loader, a maintenance contractor, and a parts manufacturer.

The driver-carrier relationship is the first thing I examine. If the driver is a W-2 employee, the carrier is vicariously liable for their actions under the doctrine of respondeat superior. If the driver is classified as an independent contractor, carriers often try to use that status to distance themselves from liability — but courts look past the label. If the carrier exercised operational control over the driver (set routes, required check-ins, controlled dispatch), courts in Texas have held the carrier liable regardless of the contractor label.

Cargo loading is underappreciated as a liability source. Improperly loaded or secured cargo shifts a truck’s center of gravity and dramatically affects handling. Under federal regulations at 49 C.F.R. Part 393, the carrier and shipper share responsibility for proper securement. If a load shifted before a rollover or jackknife, the shipper or third-party loading company may share fault.

Parts defects open the door to product liability claims against manufacturers. Brake system failures, tire defects, and steering component failures have all been the subject of major trucking litigation. The FindLaw database on product liability gives a useful overview of how these claims are structured. In a defect case, the manufacturer can be held strictly liable — meaning you do not need to prove negligence, only that the defect existed and caused the crash.

Government entities occasionally enter the picture as well. If a poorly maintained road surface, a missing guardrail, or a defective traffic signal contributed to the crash on a road maintained by TxDOT or Dallas County, a governmental claim may be filed — though the notice requirements and damages caps under the Texas Tort Claims Act apply.

Where to Find Attorneys for Truck Accident Brain Injuries in Texas?

Brain injuries are among the most serious outcomes of commercial truck crashes, and they require a lawyer with specific experience in both trucking liability and catastrophic injury damages. According to Johns Hopkins Medicine, traumatic brain injuries range from mild concussion to severe TBI with permanent cognitive and physical deficits — and the full extent of injury often does not appear for weeks or months after the crash.

For Texas victims, the place to start is with a firm that has handled TBI cases specifically in the trucking context, not just general personal injury. You want someone who understands both the FMCSA regulatory framework and how to present future medical cost evidence — including life care planning, neuropsychological testimony, and vocational rehabilitation analysis — to a jury or in mediation.

Our Texas brain injury attorneys at Dashner Law Firm have handled brain injury claims arising from commercial vehicle crashes throughout North Texas. You can also check the American Bar Association’s lawyer referral resources or Justia’s Texas attorney directory to identify attorneys who specifically list traumatic brain injury and commercial trucking among their practice areas.

Whatever you do, do not sign any agreement with the truck carrier’s insurer before consulting a lawyer. Insurance adjusters for carriers are trained to close brain injury claims early, before the full neurological picture is known. A traumatic brain injury that appears mild at the emergency room can result in years of cognitive therapy, lost earning capacity, and permanent disability. Settling before that picture is clear forfeits compensation you will need.

What to Look for in a Truck Accident Attorney in Texas?

Beyond advertised results, a few specific things separate effective truck accident lawyers from general practitioners who take the occasional trucking case.

FMCSA regulatory knowledge. Federal Motor Carrier Safety Administration regulations govern driver qualifications, hours of service, vehicle maintenance, and cargo securement. A lawyer who cannot discuss these regulations in detail during an initial consultation is not sufficiently specialized for a complex trucking case.

Access to accident reconstruction and industry experts. Truck accident cases routinely require expert testimony from accident reconstructionists, trucking industry safety experts, and medical specialists. The American Bar Association notes that expert witness management is one of the most resource-intensive aspects of complex personal injury litigation. A solo practitioner with no relationships in this space will struggle.

Trial experience specifically in trucking cases. Most cases settle — but the settlement value of your case is directly related to how credibly your attorney can threaten trial. A carrier’s defense team knows which lawyers try cases and which ones fold at the mediation table.

Transparency about fee structure. Truck accident attorneys in Texas typically work on contingency, meaning no fee unless you recover. Standard contingency fees run 33% pre-suit and 40% if the case goes to litigation, though this varies. Ask about costs — depositions, expert fees, filing fees — and whether those come off the top of any recovery or are handled separately.

How to Choose a Truck Accident Lawyer in Texas?

Choosing a lawyer after a serious truck crash is a decision made under stress, often while you or someone you love is still recovering. A few practical filters help.

Start with a free consultation — nearly every truck accident attorney in Texas offers one. Use that conversation to ask two specific questions: How many commercial trucking cases have you handled in the last three years? And have you taken any of those to trial? The answers will tell you more than any website.

Check the State Bar of Texas’s attorney search tool to confirm licensure and review any disciplinary history. The Bloomberg Law database and public court records can show whether an attorney has actually litigated federal trucking cases, not just settled them quietly.

Look at results. Not every case is the same, but a pattern of significant recoveries in trucking cases — particularly against major carriers and their insurers — shows the firm knows how to build and present these claims effectively.

Geography matters less than it used to, given electronic filing and remote depositions, but a lawyer familiar with Dallas County and Tarrant County courts — where Irving-area cases are often filed — has practical advantages in knowing local judges, local juries, and the regional defense bar.

Finally, pay attention to how your calls and questions are handled from the start. If you cannot reach the attorney or their team during the intake process, that pattern will continue throughout your case.
