Why Truck Accident Claims Are Different
A collision with a commercial truck is not a large car accident. The weight difference means injuries are more severe, the coverage involved is far larger than a personal auto policy, and the motor carrier and its insurer usually have investigators working the scene before you leave the hospital. The claim is decided by who moves first on the evidence and by whether every responsible party is identified.
Who Can Be Held Responsible
In a car crash there is usually one defendant. In a truck crash there can be several, and California Civil Code section 1431.2 makes finding all of them essential: each defendant pays the full economic damages but only its own share of non-economic damages, so a missed defendant is money the family never recovers. Depending on the facts, responsibility can reach:
- The driver, for fatigue, speed, distraction, impairment, or unsafe lane changes.
- The motor carrier that employed the driver. California law generally holds employers responsible for the negligence of employees acting within the scope of their work, and a carrier can also be directly liable for negligent hiring, training, supervision, or unrealistic schedules.
- The owner of the tractor or trailer, when they are different companies, for maintenance failures.
- The shipper or loading company, for cargo that was overloaded or improperly secured.
- A freight broker, in some circumstances, for placing the load with an unsafe carrier.
- Maintenance contractors and parts manufacturers, for brake, tire, or coupling failures.
- A public entity, if a government truck was involved or a dangerous road condition contributed. Government Code section 911.2 then requires a written claim within six months.
Evidence That Exists Only in Truck Cases
Commercial trucks and the companies that run them generate records a passenger car never does. Federal and California rules require motor carriers to keep many of these records, but only for limited periods, and nothing stops a carrier from letting them expire on schedule. Our first act in every truck case is a written preservation demand covering:
- Engine control module and event data recorder downloads showing speed, braking, and throttle in the seconds before impact.
- Electronic logging device data and hours of service records, which show whether the driver was over hours.
- Dispatch records, delivery schedules, and communications with the driver.
- The driver qualification file, including licensing, medical certification, training, and prior violations.
- Post-crash drug and alcohol test results.
- Inspection, maintenance, and repair records for the tractor and trailer.
- Dashcam and cab-facing camera footage, GPS and telematics data.
- Bills of lading, weight tickets, and cargo securement documentation.
We pair those records with an independent scene investigation, witness interviews, and a reconstruction expert when the carrier disputes fault.
How These Crashes Happen
The patterns repeat: a fatigued driver who drifted or failed to brake in time; speed that was legal but unsafe for a loaded rig in traffic or rain; a lane change into a blind spot on the 101, 405, or 118; cargo that shifted or spilled; brakes that were out of adjustment; a following distance that left no room to stop; and underride collisions where a car goes beneath a trailer. Each pattern points to specific records, which is why the preservation demand goes out before the insurer has finished its own file.
What You Can Recover and When You Must Act
Civil Code section 1431.2(b) covers economic damages such as medical expenses, loss of earnings, and the cost of substitute household services, and non-economic damages such as pain, suffering, mental suffering, and loss of consortium. Serious truck injuries usually require a life care plan and vocational evidence to prove future medical costs and lost earning capacity. When a crash is fatal, the family’s claim is governed by the rules on our wrongful death page. Code of Civil Procedure section 335.1 sets a two year deadline to file suit, and the six month government claim deadline applies when a public agency is involved.
How We Handle Truck Cases
The carrier’s insurer will contact you quickly, sometimes with a check and a release. Do not sign anything and do not give a recorded statement. Once we are retained, all contact goes through us, the preservation demand goes out, and we begin identifying every policy and every defendant. There are no attorney’s fees unless we win. The consultation is free, and we handle truck cases throughout Los Angeles County, the San Fernando Valley, and statewide.
