In a Texas 18-wheeler accident, liability can fall on the truck driver, the trucking company, a cargo loading contractor, the vehicle manufacturer, or any combination of those parties. Identifying every liable defendant is one of the most important steps in an 18-wheeler injury case because it directly determines how much insurance coverage is available to compensate you.

The Truck Driver
The most obvious starting point is the driver behind the wheel. A commercial truck driver can be found negligent for a wide range of conduct, including:
- Fatigued driving in violation of FMCSA hours of service rules under 49 CFR Part 395
- Distracted driving — phone use, GPS manipulation, or eating while operating the vehicle
- Speeding or aggressive driving on high-traffic corridors like the I-2/US-83 route through McAllen
- Driving under the influence of drugs or alcohol
- Failure to perform pre-trip inspections as required by 49 CFR Part 396
When a driver violates a federal regulation and that violation causes a crash, the legal doctrine of negligence per se may apply. Under negligence per se, the violation of a statute or regulation is treated as direct evidence of negligence, shifting the burden significantly toward the defendant.
The Trucking Company
In most commercial truck accident cases in Texas, the employer — the trucking company — carries more insurance and more legal exposure than the individual driver. There are several independent theories under which a trucking company can be held liable.
Respondeat Superior (Vicarious Liability)
Under the doctrine of respondeat superior, an employer is legally responsible for the negligent acts of an employee committed within the scope of employment. If the truck driver was on duty and performing a work-related task when the crash occurred, the trucking company is vicariously liable for the driver’s negligence. This doctrine applies even if the company did nothing directly wrong.
Negligent Hiring and Retention
A trucking company has an independent duty to screen drivers before hiring them and to remove dangerous drivers from service. If a company hired a driver with a history of DUIs, prior serious accidents, or a suspended commercial driver’s license (CDL), the company can face a negligent hiring claim. Federal Motor Carrier Safety Administration (FMCSA) regulations require carriers to investigate driver background, review motor vehicle records, and verify medical certifications before putting a driver behind the wheel.
Negligent Supervision and Training
Beyond the initial hire, trucking companies are responsible for ongoing driver supervision and training. A company that fails to enforce its own hours of service policies, ignores repeated ELD (electronic logging device) violations, or skips required performance reviews can be held liable when those failures contribute to a crash.
Negligent Maintenance
Under 49 CFR Part 396, motor carriers must systematically inspect, repair, and maintain all commercial vehicles in their fleet. Brake failures, tire blowouts, defective lighting, and steering system failures caused by deferred maintenance give rise to direct negligence claims against the carrier. Maintenance records are discoverable in litigation and often reveal patterns of neglect.
Cargo Loaders and Shippers
When improperly loaded or secured cargo causes an accident — whether through a load shift that destabilizes the trailer, falling debris that strikes other vehicles, or an overweight truck that cannot brake safely — the party responsible for loading can share liability. Under 49 CFR Part 393, cargo must be properly distributed and secured. If a third-party shipper or loading dock contractor violated these standards, they may be named as a defendant alongside the carrier.
Overloaded trucks are a known hazard on Texas roads. An 18-wheeler legally loaded to the federal maximum of 80,000 pounds requires significantly more stopping distance than a passenger vehicle. Any excess weight beyond the legal limit compounds that danger and creates additional liability exposure.
The Truck or Parts Manufacturer
If a mechanical defect in the truck, trailer, braking system, tires, or another component contributed to the crash, the manufacturer of that component can be held liable under a products liability theory. Products liability claims do not require proof of negligence — they require proof that the product was defective and that the defect caused injury. These claims can be pursued in addition to negligence claims against the driver and carrier.
Why Multiple Defendants Matter
Pursuing all potentially liable parties is not just a legal strategy — it is a practical necessity. A single truck driver is unlikely to have personal assets sufficient to compensate a victim for catastrophic injuries, long-term disability, or wrongful death. Commercial trucking companies, on the other hand, are required by federal law to carry substantial minimum insurance coverage.
Under 49 CFR § 387.9, the minimum liability insurance required for carriers transporting general freight in interstate commerce is $750,000. Carriers hauling hazardous materials must carry between $1,000,000 and $5,000,000. Many large carriers carry policies well above these minimums. When multiple defendants are named — driver, company, loader, manufacturer — the combined available coverage increases substantially.
Texas courts also recognize joint and several liability in certain circumstances, meaning that when multiple defendants share fault, each can potentially be held responsible for the full judgment amount depending on their percentage of fault and the specific facts of the case.
Evidence That Establishes Liability
Building a liability case against multiple defendants requires rapid evidence collection. Trucking companies dispatch their own accident response teams — investigators, adjusters, and defense attorneys — to crash scenes within hours of a serious accident. These teams begin preserving evidence favorable to the company and limiting the company’s exposure immediately.
Key evidence in an 18-wheeler liability case includes:
- Electronic logging device (ELD) records and black box (EDR) data, which are typically overwritten within 30 days
- Driver qualification files, drug and alcohol testing records, and CDL history
- Maintenance and inspection records for the specific vehicle involved
- FMCSA safety rating and inspection history for the carrier
- Dashcam and traffic camera footage
- Eyewitness statements and police reports
- Cell phone records establishing distraction at the time of the crash
An attorney who handles 18-wheeler cases can issue a spoliation letter demanding that the trucking company preserve all of this evidence before it is destroyed or overwritten. Without that letter, critical data may be gone before litigation begins.
Texas Statute of Limitations
Under Texas Civil Practice and Remedies Code § 16.003, personal injury claims must be filed within two years of the date of the accident. While two years may seem like sufficient time, the reality is that the most important evidence — EDR data, ELD logs, maintenance records, and dashcam footage — must be preserved in the first days and weeks following the crash. Waiting significantly reduces the strength of any case.
Frequently Asked Questions
Can I sue both the truck driver and the trucking company?
Yes. In most 18-wheeler accident cases in Texas, you can name both the driver and the trucking company as defendants. The company is often the more important defendant because it carries substantially more insurance coverage and may have independent liability for negligent hiring, supervision, or maintenance.
What is vicarious liability in a truck accident case?
Vicarious liability, also called respondeat superior, means an employer is legally responsible for the negligent actions of its employee when those actions occur within the scope of employment. If a truck driver negligently caused your crash while on the job, the trucking company is vicariously liable even if the company itself did nothing wrong.
What if the truck driver was an independent contractor?
Trucking companies sometimes classify drivers as independent contractors to avoid liability. Texas courts and federal regulators look at the actual working relationship, not just the label. If the company controlled the driver’s routes, schedule, or equipment, a court may find that the driver was effectively an employee, making the company liable.
How does cargo loading affect liability?
If improperly secured or distributed cargo caused or contributed to the crash, the party responsible for loading — whether the trucking company itself or a third-party shipper — can be held liable. Federal regulations in 49 CFR Part 393 set mandatory cargo securement standards, and violations of those standards are evidence of negligence.
How much insurance does a trucking company have to carry?
Under 49 CFR § 387.9, commercial carriers transporting general freight must carry a minimum of $750,000 in liability insurance. Carriers hauling hazardous materials must carry $1,000,000 to $5,000,000. Many large carriers maintain policies that exceed these minimums, and umbrella policies can push total coverage significantly higher.
What is negligent entrustment in a truck accident case?
Negligent entrustment occurs when a trucking company allows a driver it knew or should have known to be incompetent or unfit to operate one of its vehicles. If a company allowed a driver with a disqualified CDL, a history of serious violations, or known substance abuse issues to operate a commercial truck, the company can be directly liable under this theory.
Does it matter if the truck driver was cited at the scene?
A traffic citation is relevant evidence of negligence, but it is not required to pursue a claim, and it does not automatically resolve the civil case. Many seriously negligent drivers are never cited at the scene. The civil standard — preponderance of the evidence — is lower than the criminal standard, and violations of FMCSA regulations can establish negligence even without a citation.
