Crashes involving 18-wheelers and semi-trucks are fundamentally different from standard car accidents — and nowhere is that more apparent than in how claims are investigated, who gets held liable, and what the legal process typically looks like. If you've been involved in a truck accident in San Antonio, understanding how these cases generally work can help you make sense of what's ahead.
A collision with a commercial semi-truck doesn't just involve two drivers. Depending on the circumstances, multiple parties may share liability: the truck driver, the trucking company, the cargo loader, a maintenance contractor, or even a truck manufacturer if an equipment defect contributed to the crash.
Texas operates under an at-fault system, meaning the party (or parties) responsible for causing the accident are generally responsible for resulting damages. Texas also follows a modified comparative fault rule — sometimes called proportionate responsibility. Under this framework, an injured party can recover damages as long as they are not found to be more than 50% at fault. If you bear some portion of fault, your recoverable damages are typically reduced by that percentage.
Commercial trucks operating in Texas and across state lines are subject to Federal Motor Carrier Safety Administration (FMCSA) regulations. These rules govern:
When a trucking company or driver violates these regulations, those violations can become significant evidence in a liability determination. This is one reason truck accident investigations often involve subpoenas for driver logs, black box (electronic logging device) data, and company maintenance records — material that typically doesn't exist in ordinary car accident cases.
Liability investigations in 18-wheeler cases tend to be more intensive than those in standard crashes. Here's what that process often includes:
| Investigation Element | What It Examines |
|---|---|
| Police/crash report | Basic facts, citations issued, initial fault indicators |
| Electronic logging device (ELD) data | Driver hours, speed, braking before impact |
| Trucking company records | Driver history, training, compliance with FMCSA rules |
| Cargo manifests | Whether the truck was properly loaded and within weight limits |
| Surveillance or dashcam footage | Visual record of the crash sequence |
| Expert reconstruction | Professional analysis of how the crash occurred |
Trucking companies typically have rapid response teams — lawyers and investigators who can reach a crash scene quickly. This is relevant context for understanding why early documentation and evidence preservation are commonly discussed in truck accident cases.
Texas law recognizes several categories of compensable damages in personal injury claims:
⚖️ The actual value of any claim depends heavily on injury severity, treatment duration, wage documentation, insurance coverage limits, and how fault is apportioned. These figures vary significantly from case to case.
Commercial trucking companies are required under federal law to carry minimum liability coverage — often substantially higher than what applies to personal auto policies. The minimum varies by cargo type and interstate operation, but FMCSA-regulated carriers hauling general freight must carry at least $750,000 in liability coverage. Carriers transporting hazardous materials may be required to carry $1 million to $5 million or more.
In practice, this means the insurance dynamics in truck cases differ from standard auto claims. Rather than dealing with a personal auto insurer, injured parties are often negotiating with commercial carriers and their specialized claims adjusters — who are experienced in minimizing payouts on large claims.
Your own underinsured/uninsured motorist (UM/UIM) coverage, MedPay, or Personal Injury Protection (PIP) may also come into play depending on your policy and the circumstances.
Personal injury attorneys who handle truck accident cases in San Antonio almost universally work on a contingency fee basis — meaning they collect a percentage of any settlement or verdict, typically ranging from 33% to 40%, and collect nothing if the case doesn't result in recovery. This structure means upfront legal costs are generally not required from the injured party.
🔍 Attorneys in these cases typically handle evidence preservation, communication with insurers, expert coordination, and — if necessary — litigation. Given the complexity of federal trucking regulations and the resources trucking companies bring to their defense, legal representation in 18-wheeler cases is more commonly sought than in minor fender-benders.
Texas generally imposes a two-year statute of limitations for personal injury and wrongful death claims — but deadlines can shift based on the injured party's age, whether a government entity is involved, or other case-specific factors. Missing a filing deadline typically bars recovery entirely, regardless of how strong a claim might otherwise be.
The timeline from accident to resolution in truck cases can range from several months to multiple years, depending on injury complexity, liability disputes, and whether the case goes to trial.
No two truck accident claims resolve the same way. The variables that matter most include:
The general framework described here applies broadly — but how Texas law applies to the specific facts of any individual crash is what ultimately determines how a claim unfolds.
