When a commercial truck is involved in a crash, the legal landscape is more complicated than a standard car accident case. Federal regulations govern how trucking companies operate, how drivers are trained and monitored, how vehicles are maintained, and how long a driver can be behind the wheel before stopping to rest. When those regulations are violated, the violation becomes evidence in a lawsuit.
Understanding how federal trucking law connects to civil liability can help you see why these cases are different, what evidence matters most, and why acting quickly after a truck crash is not optional.
The Federal Agency Behind Trucking Rules
The Federal Motor Carrier Safety Administration sets the rules that govern commercial trucking across the United States. The FMCSA operates under the Department of Transportation and has the authority to establish safety standards for carriers, drivers, and vehicles operating in interstate commerce.
These regulations cover a wide range of conduct: how many hours a driver can work in a single shift, what a trucking company must do to verify a driver’s qualifications before hiring, how often vehicles must be inspected and what records must be kept, what cargo weight limits apply, and how hazardous materials must be handled and documented.
The Federal Motor Carrier Safety Administration publishes its full regulatory framework publicly, and that database becomes a critical reference point in any truck accident lawsuit. When a plaintiff’s attorney argues that a carrier violated federal safety rules, those specific regulations are cited by number.
Why Federal Violations Matter in a Civil Case
A violation of an FMCSA regulation does not automatically create civil liability, but it is powerful evidence of negligence. Texas courts, like courts in most states, recognize the concept of negligence per se: when a party violates a law or regulation designed to protect the public from a specific type of harm, that violation can establish the breach of duty element of a negligence claim without requiring additional proof that the conduct was unreasonable.
In plain terms, if a trucking company required a driver to operate for 14 consecutive hours in violation of federal hours-of-service rules, and that fatigued driver caused a crash, the regulatory violation is direct evidence of negligence. The plaintiff does not have to persuade a jury that driving 14 hours without rest is dangerous. The federal government already made that determination.
This matters because it shifts the burden. Instead of arguing about whether the conduct was unreasonable, your attorney focuses on whether the violation occurred and whether it caused the crash.
Hours-of-Service Rules and Fatigue
Hours-of-service regulations are among the most frequently violated FMCSA rules in serious truck accident cases. Under current federal rules, most commercial truck drivers are limited to 11 hours of driving time within a 14-hour window after coming on duty, following a minimum 10-hour off-duty period. Drivers are also capped at 60 hours of driving in 7 consecutive days or 70 hours in 8 consecutive days.
These limits exist because fatigue is a documented cause of serious crashes. A driver who has been awake for 18 hours experiences impairment comparable to a blood alcohol concentration of 0.08.
Trucking companies are required to maintain electronic logging device records for every driver. These records track when the engine was running, how far the truck traveled, and how long the driver was on duty. In litigation, your attorney subpoenas those ELD records. When the logs show a driver exceeded the legal hours before a crash, that evidence is difficult to explain away.
Some carriers have been found to falsify paper logs to conceal hours-of-service violations. When electronic records contradict paper logs, the discrepancy itself becomes evidence of a cover-up, which can support a punitive damages claim.
Driver Qualification and Hiring Requirements
The FMCSA requires trucking companies to verify specific qualifications before putting a driver on the road. Carriers must confirm the driver holds a valid commercial driver’s license for the type of vehicle and cargo being operated, review the driver’s employment history for the prior three years, obtain a motor vehicle record from every state where the driver held a license in the past three years, conduct a road test or verify equivalent prior qualification, and check the FMCSA Drug and Alcohol Clearinghouse for prior violations.
When a carrier skips these steps or hires a driver despite a history of serious traffic violations, failed drug tests, or prior crashes, the carrier is exposed to negligent entrustment claims on top of direct negligence claims. If the driver who caused your crash had a prior DWI on their record and the carrier never checked, that is not just a regulatory violation. It is evidence that the company put a known risk on the road.
Texas courts take negligent hiring seriously. The damages exposure in cases involving hiring failures is often higher than in cases involving only the driver’s conduct, because the carrier’s decision-making is directly implicated.
Vehicle Maintenance and Inspection Requirements
Federal regulations require commercial carriers to systematically inspect, repair, and maintain every vehicle in their fleet. Drivers must conduct a pre-trip inspection before every shift and submit a written vehicle inspection report at the end of each day. Any defect that affects safe operation must be repaired before the vehicle returns to service.
Carriers must keep maintenance records for each vehicle, including inspection reports, repair orders, and documentation of when defects were identified and corrected.
Brake failures, tire blowouts, and steering defects are among the most common mechanical causes of serious truck crashes. When maintenance records show a known defect was not repaired, or when records are missing entirely, that gap in documentation becomes a central issue in the lawsuit.
In one type of case that comes up regularly in Texas commercial litigation, a tire blowout causes a driver to lose control. The plaintiff’s attorney subpoenas the maintenance records for that specific tire and axle. If the records show the tire was flagged in a prior inspection and not replaced, the carrier’s failure to act is negligence. If no records exist at all, the absence of documentation raises its own questions.
Cargo Loading and Weight Limit Violations
Federal regulations set maximum weight limits for commercial trucks operating on public roads. A standard 18-wheeler is limited to 80,000 pounds gross vehicle weight on most interstate highways. Exceeding that limit affects braking distance, handling, and the risk of rollover.
Cargo must also be properly secured. The FMCSA’s cargo securement rules specify how different types of cargo must be tied down, what equipment must be used, and how loads must be distributed across axles.
When improperly loaded or overweight trucks cause crashes, liability may extend beyond the carrier to the company that loaded the trailer. If a third-party shipper was responsible for securing the load and the load shifted during transport, the shipper can be named as a defendant alongside the carrier.
This is one of the reasons truck accident cases often involve multiple defendants. Identifying all of them requires understanding the full chain of custody for the vehicle, the cargo, and the route.
Drug and Alcohol Testing Requirements
Commercial truck drivers are subject to federal drug and alcohol testing requirements that go well beyond what applies to regular employees. Pre-employment testing is required before a driver operates a commercial vehicle. Post-accident testing is required whenever a crash results in a fatality, a citation to either driver combined with an injury requiring medical treatment away from the scene, or a citation combined with a vehicle being towed.
Carriers are required to test drivers randomly throughout the year, with a minimum annual rate of 50% of their driver pool for drugs and 10% for alcohol. They must also test when reasonable suspicion exists and upon return to duty after a violation.
When a carrier fails to conduct required post-accident testing, that failure itself is a regulatory violation. If subsequent evidence suggests the driver was impaired and no test was done, the company’s failure to test becomes a significant fact in the litigation.
Black Box and Electronic Data in Truck Crash Cases
Modern commercial trucks carry event data recorders that capture vehicle speed, braking inputs, engine throttle position, and other operational data in the seconds before a crash. This data is preserved on the truck’s electronic control module and can be downloaded by trained technicians.
This evidence is often decisive. In cases where the driver claims they were driving safely and the truck’s own data shows they were traveling 72 miles per hour in a 55-mile-per-hour zone without braking, the black box resolves the dispute directly.
The problem is that this data can be overwritten. Many systems store only a limited window of data, and if the truck continues to operate after the crash, earlier recordings may be lost. This is why sending a spoliation letter to the carrier immediately after a serious truck crash is standard practice. The letter places the carrier on legal notice to preserve all electronic data, maintenance records, driver logs, and communications. If the carrier destroys evidence after receiving that notice, courts can instruct the jury to draw an adverse inference.
Insurance Requirements and What They Mean for Your Claim
Federal regulations require commercial carriers to carry minimum liability insurance based on the type of cargo they haul. Most general freight carriers operating in interstate commerce must carry at least $750,000 in liability coverage. Carriers transporting hazardous materials are required to carry between $1 million and $5 million depending on the specific cargo.
These minimums are higher than what most passenger vehicle drivers carry, which is part of why truck accident claims can produce larger recoveries than standard car accident cases. But insurance coverage and actual liability are different things.
Carriers and their insurers have experienced claims teams who begin working the case from the moment a crash is reported. Understanding how commercial trucking insurance interacts with liability in serious crash cases is worth reading up on. This resource on commercial truck insurance and coverage structures provides useful context on how carriers think about their coverage and risk exposure.
Who Can Be Held Liable in a Truck Crash
A truck crash lawsuit rarely names only the driver. Depending on the facts, liable parties can include the trucking company as the driver’s employer, the owner of the trailer if it is leased separately from the cab, the company that loaded or secured the cargo, the manufacturer of a defective component, the entity responsible for road maintenance if a road defect contributed, and a broker who arranged the shipment if the broker exercised control over how it was carried.
Texas follows a modified comparative fault rule. If multiple defendants share responsibility, the jury apportions fault among them. Each defendant is liable for their percentage of the total damages, though under Texas law, defendants found more than 50% responsible are jointly and severally liable for the full economic damages.
Identifying all liable parties and building the evidence to support claims against each requires a thorough investigation, access to records, and in many cases the work of accident reconstruction experts.
Why Acting Fast Matters
Evidence in truck crash cases disappears quickly. Black box data gets overwritten. Trucks are repaired and returned to service. Drivers move to new carriers. Witnesses become harder to locate. The carrier’s internal communications about the crash are more accessible before litigation than after a year of document management.
Preserving evidence requires legal action before that window closes. A spoliation notice, a records request, and in some cases an emergency motion to preserve evidence are tools your attorney uses in the first days after a serious crash.
If you were seriously injured in a truck accident in Corpus Christi or the surrounding area, Carrigan & Anderson’s truck accident team handles these cases with the investigative resources serious truck crash litigation requires.
What to Do After a Truck Crash
Get medical care immediately, even if you believe your injuries are minor. Truck crashes involve significant force, and internal injuries, spinal damage, and traumatic brain injuries may not be fully apparent in the first hours.
Do not give a recorded statement to the trucking company’s insurer. You are not required to, and the statement will be used to minimize your claim.
If you can do so safely, photograph the scene, the vehicles, the road, skid marks, and any visible cargo. Get the truck’s license plate and the carrier’s DOT number, which is displayed on the side of the cab.
Write down everything you remember about the crash as soon as you are able. Specific details about speed, the truck’s behavior before the crash, weather, road conditions, and what the driver said at the scene can all matter later.

Federal trucking regulations exist because commercial trucks are among the most dangerous vehicles on public roads. When those regulations are violated and someone gets hurt, the violation is not just a paperwork problem. It is evidence of the negligence that caused your injury, and it belongs at the center of your legal claim.
