Truck Accident Claims in California: How They Differ from Car Crashes

How California truck accident claims work: who can be liable, the deadlines that apply, and why commercial-vehicle cases differ from ordinary car crashes.

A California truck accident claim is a personal injury or wrongful death action seeking compensation for harm caused by a commercial vehicle. Under Code of Civil Procedure section 335.1, most injury claims must be filed within two years. Trucking cases often involve multiple defendants and federal safety regulations, making them more complex than car crashes.

Why truck cases are not just bigger car cases

When people search "truck accident lawyer," they usually want to know why a collision with an 18-wheeler or delivery truck is treated differently from a fender-bender. The short answer: commercial trucks are governed by layers of law that passenger cars are not, and the injuries tend to be far more severe.

A loaded tractor-trailer can weigh many times what a passenger car does, so the same physics produces catastrophic harm — spinal injuries, traumatic brain injuries, and fatalities. That severity raises the stakes for both sides and usually means insurers and defense counsel are involved early.

The legal framework also differs. Interstate motor carriers are subject to the Federal Motor Carrier Safety Regulations (49 C.F.R. Parts 350–399), which govern driver hours, vehicle maintenance, drug testing, and record-keeping. California also enforces commercial-vehicle rules through the Vehicle Code. Violations of these rules can be central evidence in a claim.

Who can be held responsible

Car crashes usually involve two drivers. Truck cases can involve a chain of parties, and identifying each one matters because it affects who pays.

Potential defendantWhy they may be liable
The truck driverNegligent driving — speeding, fatigue, distraction
The trucking companyIts driver's negligence; negligent hiring, training, or supervision
The vehicle ownerSeparate from the carrier in leased-fleet arrangements
A maintenance contractorFaulty brake or tire servicing
A cargo loaderImproperly secured or overweight loads
A parts manufacturerDefective equipment

An employer is generally responsible for the negligent acts of an employee committed within the scope of employment, a principle California courts apply broadly. Sorting out employee versus independent-contractor status, and which insurance policy responds, is often the most contested part of a trucking case.

Evidence that disappears quickly

Trucks generate data that ordinary cars do not, and much of it can be lost or overwritten if no one acts. Relevant evidence often includes:

  • Electronic logging device (ELD) data showing hours of service and whether the driver exceeded federal limits.
  • The engine control module ("black box") recording speed, braking, and throttle before impact.
  • Driver qualification files, inspection records, and maintenance logs the carrier is required to keep under federal rules.
  • Dashcam or telematics footage.

Because carriers control this evidence and retention periods are limited, injured people frequently send a preservation (spoliation) letter early to demand the company keep it. Waiting can mean routine deletion of the exact records that establish fault.

Deadlines you cannot miss

California's general deadline for personal injury claims is two years from the date of injury under Code Civ. Proc. § 335.1. Wrongful death claims carry the same two-year period.

Two wrinkles matter in truck cases:

  • Government-owned or contracted vehicles. If a public entity's truck (a city sanitation truck, for example) is involved, the Government Claims Act requires a written claim to the entity within six months under Gov. Code § 911.2 before you can sue.
  • Property damage to your vehicle has a three-year deadline under Code Civ. Proc. § 338, separate from the injury deadline.

What compensation generally covers

California law lets an injured person seek economic and non-economic damages. Economic damages include medical bills, future care, lost wages, and lost earning capacity. Non-economic damages cover pain, suffering, and loss of enjoyment of life. In a wrongful death claim, surviving family members may recover for their own losses under Code Civ. Proc. § 377.60.

California follows comparative fault: if an injured person is partly responsible, recovery is reduced by their share of fault rather than barred entirely. Because commercial carriers typically carry substantial insurance and multiple parties may share responsibility, valuing a trucking claim is more involved than a standard auto case.

Frequently asked questions

How long do I have to file a truck accident claim in California?

Most personal injury claims must be filed within two years of the crash under Code of Civil Procedure section 335.1. If a government-owned truck was involved, a written claim to the public entity is generally required within six months. Property damage claims have a three-year deadline.

Can I sue the trucking company and not just the driver?

Often, yes. An employer is generally responsible for a driver's negligence committed within the scope of employment, and the company may face separate claims for negligent hiring, training, or maintenance. Multiple parties can share responsibility in a single trucking case.

What makes truck accident cases more complicated than car accidents?

Commercial trucks are subject to federal safety regulations governing driver hours, maintenance, and record-keeping, and they generate electronic data cars do not. Cases frequently involve several potential defendants and larger insurance policies, which makes liability and evidence disputes more involved.

What evidence should be preserved after a truck crash?

Electronic logging device data, the truck's engine control module, maintenance and inspection logs, driver qualification files, and any dashcam footage are important. Because carriers control these records and retention periods are short, preservation is often requested quickly to prevent routine deletion.

Does it matter if I was partly at fault?

California follows comparative fault, so being partly responsible reduces your recovery by your share of fault rather than barring it entirely. The specific percentages and their effect depend on the facts of each case and are decided based on the evidence.
