When an 18-wheeler is involved in a crash, the aftermath looks very different from a typical two-car accident. The vehicles are heavier, the damage is usually more severe, the insurance coverage is more complex, and the list of potentially responsible parties is longer. In San Antonio — a major commercial trucking corridor where I-35, I-10, and I-37 intersect — these accidents happen with real frequency, and the questions that follow them are serious ones.
This article explains how 18-wheeler accident claims generally work, what makes them different from standard auto claims, and what variables shape outcomes.
A crash involving a semi-truck isn't just a bigger version of a fender-bender. Several features set these cases apart:
Texas follows a modified comparative fault rule (also called proportionate responsibility). Under this framework, an injured person can recover damages as long as they are found to be 50% or less at fault for the accident. However, any compensation is reduced by their percentage of fault.
Fault in a truck accident is typically established through:
Texas is an at-fault state, meaning the party responsible for causing the crash is generally responsible for the resulting damages — through their liability insurance or directly. This is different from no-fault states, where your own insurance pays certain costs regardless of who caused the accident.
In a serious 18-wheeler accident, recoverable damages generally fall into two categories:
| Damage Type | Examples |
|---|---|
| Economic damages | Medical bills, future medical costs, lost wages, loss of earning capacity, vehicle/property damage |
| Non-economic damages | Pain and suffering, emotional distress, loss of enjoyment of life, disfigurement |
| Exemplary damages | In cases involving gross negligence, Texas law allows for punitive-type damages in limited circumstances |
The actual value of any claim depends on injury severity, total medical costs, how long the person is unable to work, the degree of fault assigned, available insurance coverage, and how well damages are documented throughout treatment.
The medical record created after a crash becomes one of the most important documents in a claim. Emergency room records, diagnostic imaging, follow-up treatment notes, physical therapy records, and physician assessments all help establish the nature and extent of injuries.
Gaps in treatment — periods where someone stops seeking care — are often used by insurance adjusters to argue that injuries were less serious than claimed or that they healed. Consistent, documented treatment generally supports a stronger evidentiary record, whatever the eventual claim outcome.
Personal injury attorneys who handle truck accident cases almost always work on a contingency fee basis — meaning they receive a percentage of the settlement or court award rather than billing by the hour. If there's no recovery, there's typically no fee. Common contingency percentages range from 33% to 40%, though the exact arrangement varies by firm and case complexity.
What an attorney typically handles in a truck accident case:
Legal representation is most commonly sought when injuries are serious, liability is disputed, multiple parties may be responsible, or initial settlement offers appear low relative to actual damages.
Texas generally sets a two-year statute of limitations for personal injury claims arising from vehicle accidents — meaning a lawsuit must typically be filed within two years of the date of the crash. However, there are exceptions that can shorten or extend that window, including cases involving government vehicles, minors, or deaths.
⚠️ That two-year figure is a general reference for Texas civil claims — it is not a guarantee that it applies to every reader's specific situation. Government entities, wrongful death claims, and other circumstances can alter those timelines significantly.
After a serious 18-wheeler crash in Texas, the typical sequence involves:
The timeline varies widely. Cases with clear liability and defined injuries may resolve in months. Complex cases with disputed fault, catastrophic injuries, or multiple defendants can take years.
How any of this applies to a specific crash depends on facts that vary considerably: exactly what happened, who was driving and for whom, what insurance policies are in play, how fault is ultimately apportioned, the nature and extent of injuries, and how Texas law applies to the specific circumstances.
The general framework above describes how these cases typically work — but the outcome in any individual case is shaped by details that no general resource can assess from the outside.
