California Truck Accident Lawyer
A collision with an 80,000-pound truck is not a bigger car accident. It is a case against a company that has a safety department, a lawyer on retainer, and a document retention policy that legally permits destroying the evidence you need. The difference between a strong truck case and a weak one is usually decided in the first two weeks, before anyone has finished treating.
Why these cases are a different animal
- Interstate trucking is federally regulated. The Federal Motor Carrier Safety Regulations govern how long a driver may drive, how a truck must be inspected and maintained, how cargo must be secured, and who may be hired. A violation is powerful evidence of negligence in a way an ordinary traffic infraction is not.
- The defendant is a company, not a person. That usually means higher insurance limits and a far more organized defense. Interstate carriers hauling general freight must carry at least $750,000 in liability coverage under 49 CFR 387.9, and limits of $1 million or more are common. Carriers hauling certain hazardous materials must carry substantially more.
- There are usually several potential defendants: the driver, the motor carrier, the trailer owner, the shipper that loaded it, a broker that arranged the load, and a maintenance contractor. Each may have separate coverage.
- The evidence is electronic and perishable. Logs, engine data, dashcams and telematics all exist on retention schedules measured in months, and some in days.
The evidence that disappears
This is the part that matters most, so it comes before everything else. A letter demanding preservation, sent to the carrier and its insurer immediately, is what stops routine destruction and creates consequences if it happens anyway.
- Electronic logging device records. Since the federal ELD mandate, most interstate drivers record duty status electronically. Carriers are required to retain supporting documents for six months under 49 CFR 395.11, and the underlying records are frequently purged at the edge of that window.
- Engine control module and event data recorder downloads: speed, throttle, brake application, and hard-braking events in the seconds before impact. Requires physical access to the tractor, which a carrier will not volunteer.
- Telematics and fleet management data, which many carriers stream continuously and retain on short cycles.
- Dashcam footage, inward and outward facing. Some systems only save clips flagged by an event trigger, and unflagged footage rolls off quickly.
- The driver qualification file: license history, prior employers, road test, medical certification, and any prior violations the carrier knew about when it hired him.
- Drug and alcohol testing records. Post-accident testing is required under 49 CFR 382.303 in defined circumstances, and whether it was performed at all is itself significant.
- Maintenance and inspection records, including the daily vehicle inspection reports drivers are required to prepare under 49 CFR 396.11.
- Bills of lading, dispatch records and trip documents, which reveal the schedule the driver was being held to.
- The truck and trailer themselves, before repair, and the cargo load configuration.
Hours of service and the fatigue case
Fatigue is the most common serious-truck-crash factor that leaves a documentary trail. The federal property-carrying rules in 49 CFR 395.3 set the outer limits:
- A maximum of 11 hours of driving after 10 consecutive hours off duty.
- No driving beyond the 14th consecutive hour after coming on duty, regardless of off-duty breaks taken within that window.
- A required 30-minute break after 8 cumulative hours of driving time.
- A weekly limit of 60 hours in 7 days or 70 hours in 8 days, depending on the carrier's operation, with a restart provision.
Proving a violation means reconciling the logs against independent records: fuel receipts, toll transactions, weigh station records, GPS pings, delivery timestamps and cell site data. When the log says off duty and the fuel receipt says otherwise, the case changes character. Falsified logs also open the door to claims against the carrier for its own conduct, not just the driver's.
Claims against the company itself
A carrier is generally responsible for its driver's negligence in the course of employment under respondeat superior. But there are independent claims against the company that matter because they reach conduct a jury finds harder to forgive:
- Negligent hiring, where the driver's record or prior employment history should have disqualified him.
- Negligent training and supervision, including failing to act on a pattern of logbook or speed violations the telematics already flagged.
- Negligent retention, where the carrier kept a driver after knowing about disqualifying conduct.
- Negligent maintenance, where brake or tire condition contributed and the inspection records show the defect was known or should have been found.
- Pressure to violate hours of service, where dispatch records show a schedule that was not achievable legally.
- Negligent cargo loading and securement, which can implicate the shipper or loading facility rather than the carrier.
Broker liability is its own developing area. Where a freight broker selected a carrier with a poor federal safety rating, there may be a claim for negligent selection, subject to significant preemption arguments that have divided federal courts. Whether it is worth pursuing is a case-specific judgment, not a given.
Truck traffic in Southern California
Orange County sits in the middle of one of the heaviest freight corridors in the country. Container traffic from the Ports of Los Angeles and Long Beach moves inland on the I-710, I-605, SR-91 and I-5 corridors, and distribution traffic bound for the Inland Empire crosses the county constantly. The practical consequences show up in the cases we see: heavy drayage traffic mixing with commuter congestion on the 5 and the 91, the 57 and 91 interchange, and the SR-55 and I-405 merge.
California layers its own rules on top of the federal ones. Trucks are restricted to the right-hand lanes under Vehicle Code section 21655, and a vehicle towing a trailer is limited to 55 mph under section 22406 even where the posted limit is 65 or 70. A loaded truck traveling at posted automobile speed is already in violation, and that is frequently establishable from the same data that shows the impact.
What we do first
- Send spoliation and preservation letters to the carrier, the insurer, the trailer owner and any identified broker, listing each category of electronic evidence specifically.
- Pull the carrier's federal safety profile, including inspection history, out-of-service rates and crash history.
- Retain a reconstruction expert while the scene evidence is still measurable, and arrange inspection and data download of the tractor and trailer before repairs.
- Identify every layer of coverage, including excess and umbrella policies above the primary limits.
- Obtain the CHP report and any Multidisciplinary Accident Investigation Team materials, which exist for the most serious collisions.
- File suit early where a carrier is slow to preserve, because discovery tools and court orders are more effective than letters.

Questions people actually ask
How soon do I need a lawyer after a truck crash?
Immediately, and this is the one practice area where that is not a sales line. Electronic logs, engine data and dashcam footage sit on retention schedules measured in months and sometimes days, and a carrier has no obligation to preserve them until someone demands it in writing. Weeks of delay can permanently remove the best evidence in the case.
The police report says the truck driver was not cited. Does that end it?
No. A citation decision is made at the roadside based on what an officer can observe in an hour. It does not account for logbook falsification, brake maintenance history, a driver qualification file, or engine data showing speed and braking. Civil liability is a separate question decided on a different record.
How much insurance do trucking companies carry?
Interstate carriers hauling general freight must carry at least $750,000 in liability coverage under 49 CFR 387.9, and $1 million is a common practical floor. Higher minimums apply to certain hazardous cargo. Excess and umbrella layers are common, which is why identifying every policy early matters on a serious injury.
Can I sue the company, or only the driver?
Both, in most cases. The carrier is generally responsible for its driver's negligence on the job, and may also be independently liable for hiring, training, supervision, maintenance or dispatch practices. Independent claims against the company often matter more than the driver's own conduct.
The truck was from out of state. Where does the case go?
A crash in California generally supports a case in California, and interstate carriers operating here are subject to jurisdiction here. Where exactly it is filed depends on the county of the crash and the defendants' locations, which is a strategic decision rather than a formality.
What if I was partly at fault?
California's pure comparative fault rule still applies, so your recovery is reduced by your percentage rather than barred. In truck cases, fault allocation is often genuinely contested and is where reconstruction evidence earns its cost, because a shift of 20 percentage points on a serious injury is a large number.
