Truck and big rig accident claims
A truck case is not a bigger car case. There is a second defendant with real money, a federal rulebook the driver had to follow, and a quantity of electronic evidence that exists right now and may not exist in ninety days.
The evidence clock
This is the part that is genuinely urgent, and it is why truck cases reward early involvement more than almost any other kind.
A commercial carrier is only required to keep many of its records for a limited period. Driver logs, dispatch records and some electronic data have retention windows measured in months. A carrier that destroys records on its ordinary schedule has not necessarily done anything wrong — unless it has been told the records matter.
What the records show that nothing else can
| Electronic logging device (ELD) | Hours of service. Whether the driver had been at the wheel beyond the federal limit, and whether the log was falsified against GPS and fuel records. |
|---|---|
| Engine control module | Speed, throttle, braking and engine data in the seconds before impact. The truck's own account of the crash. |
| Driver qualification file | Licensing, medical certification, driving history and prior violations. What the company knew when it hired and kept this driver. |
| Maintenance and inspection records | Brakes, tires, lights. Deferred maintenance is a recurring theme in serious truck crashes. |
| Dispatch and load records | Whether the schedule the company set could be met lawfully. A deadline that requires a driver to break hours-of-service rules is the company's decision, not the driver's. |
| Drug and alcohol testing | Post-accident testing is federally required in defined circumstances. Whether it happened, and the result. |
Suing the company, not just the driver
The driver is usually the least significant defendant. Under ordinary principles of vicarious liability an employer is responsible for its employee's negligence committed in the course of employment, which puts the carrier's much larger policy in play immediately.
Beyond that there are claims that belong to the company alone: negligent hiring, negligent retention, negligent supervision, negligent maintenance, and negligent entrustment. These matter because they are about choices the company made, and because they survive even where the driver's own conduct is defensible.
Where this happens in Southern California
Truck traffic here is not evenly distributed. The ports of Los Angeles and Long Beach push drayage traffic along the 710, the 91 and the 60 into the Inland Empire warehouse belt, and the 15 and the 10 carry long-haul freight through to the desert. The I-5 corridor runs the length of the state.
That geography concentrates serious truck crashes in predictable places, and it means the responding agency is frequently the CHP rather than a city department — which affects how the report is produced and how the investigation can be developed.
Questions people ask
How soon do I need to do something about a truck crash?
Sooner than with a car crash. Electronic logging data, engine data and in-cab video can be overwritten or disposed of on ordinary retention schedules within months. A preservation letter stops that clock. It is the one thing in injury practice that is genuinely time-critical in the first weeks rather than the first years.
The trucking company's insurer called me within a day. Is that normal?
Yes, and it tells you something. Large carriers often have rapid response arrangements that put an investigator at the scene within hours. They are gathering evidence and statements while you are still in the hospital. That is their right. It is also a reason not to be the only unrepresented party in the conversation.
Can I sue the trucking company and not just the driver?
In most cases yes, and you usually should. An employer is responsible for an employee's negligence in the course of employment, and there are separate claims against the company for hiring, retaining, supervising or dispatching the driver as it did, and for maintaining the vehicle as it did.
What if the truck driver was an owner-operator and not an employee?
It does not necessarily end the claim against the carrier. Federal motor carrier regulation makes the operating authority holder responsible in circumstances where ordinary employment law would not, and the question of who controlled the work is a factual one rather than a matter of what the contract calls them.
