7 Critical Moves Your Los Angeles Truck Accident Attorney Must Make

Federal regulations require all commercial motor vehicles to use electronic logging devices (ELDs). The ELD records when the driver was on duty, off duty, sleeper berth, or on break. If a crash happened in hour 12 and the regulations allow only 11 hours of consecutive driving, that's a federal violation—and exactly the kind of violation trucking companies try to bury. Your attorney needs a preservation letter to the motor carrier within 72 hours, before their legal team starts coordinating with dispatch to "clarify" records. ELD data also logs harsh events: rapid acceleration, hard braking, lane drift. A dash cam showing the same behavior pattern the ELD recorded strengthens your case. Under [FMCSA regulations](https://www.fmcsa.dot.gov/), carriers must maintain ELD records for at least 24 months. California courts have admitted ELD logs as business records in hundreds of verdicts. Without this data, you're defending a negligence case with incomplete evidence.

The driver's qualification file (DQF) is a federal requirement. It contains the driver's medical certification, prior employment history, motor vehicle record, and any safety violations. A disqualifying medical condition—sleep apnea, uncontrolled diabetes, vision impairment—is hidden liability for both the driver and the motor carrier that hired them. California employers have a duty to vet their drivers. A motor carrier that hired a driver with an expired DOT physical or a history of multiple crashes is liable for negligent hiring. Request three years of DOT medical certifications and the complete motor vehicle record from the California Department of Motor Vehicles. If the driver had prior at-fault crashes or license suspensions, that pattern supports a negligence claim directly against the carrier. Most trucking companies will resist this discovery aggressively. That's precisely why your attorney files for it immediately, within the first week.

The Compliance, Safety, Accountability (CSA) program ranks every motor carrier on metrics like unsafe driving, hours-of-service violations, vehicle maintenance failures, and hazardous materials violations. [The FMCSA publishes CSA scores publicly](https://www.fmcsa.dot.gov/), searchable by carrier name. If the carrier's score exceeds the intervention threshold—meaning FMCSA has flagged them as unsafe—that's evidence of a pattern of negligence. A carrier with a CSA score above 69 in the unsafe driving category has demonstrated a company-wide safety culture problem. In California courts, CSA data supports claims of negligent hiring, retention, and supervision. The trucking company can't argue they had no notice. The FMCSA gave them public notice. Defense attorneys know this data exists and will argue it's irrelevant—your job is to make it central to the negligence narrative and demand higher settlement terms based on the carrier's track record.

Dispatch logs, text messages, radio communications, and email between the motor carrier and driver are often the most damaging evidence. Was dispatch pushing the driver to meet an impossible deadline? Did the dispatcher know the driver had already violated the 11-hour rule? Did the driver report brake problems that dispatch ignored? These communications show knowledge and recklessness. California law addresses spoliation: if a party destroys relevant evidence, courts may infer the destroyed evidence would have supported your case. A preservation letter from your attorney—served on the motor carrier and their insurance carrier within 72 hours—triggers a legal duty to preserve all communications. Without that letter, the motor carrier's IT team may legally delete texts and emails after 30 or 60 days per their standard retention policy. With it, deletion becomes destruction of evidence and opens the door to additional damages and sanctions.

The driver is rarely the only liable party in a commercial truck accident. The motor carrier (employer) may be liable for negligent hiring, retention, or supervision. The shipping broker may have imposed impossible deadlines that forced speed. The shipper may have loaded cargo improperly, creating an unstable load that caused a rollover. The trailer owner may have failed to maintain brakes or tires. The loader may have placed weight outside the GVWR limits. Each of these parties has insurance, and each has a potential share of liability. California allows joint and several liability, meaning you can recover the full settlement from any single liable party—then let their attorneys sort out contribution among themselves. Motor carriers are required to carry liability insurance of at least $750,000 per incident under federal law. Brokers, shippers, and loaders often carry separate coverage. A competent truck accident attorney in Los Angeles files against all responsible parties.

Skid marks fade. Debris is cleared. Roadway paint and guardrail damage are repaired. Vehicle damage photographs are first-line evidence—taken at the scene by first responders or your own investigator. Request the Los Angeles Police Department's crash report on city streets; the California Highway Patrol handles freeway incidents on I-10 and I-405. The report includes officer observations about skid marks, vehicle positions, and contributing factors. Hire an accident reconstruction expert to photograph the scene within 48 hours. Mark measurements. Document sight lines. Photograph the driver's view at the point of impact. Request weather data, traffic signal timing, and any available camera footage from nearby businesses or traffic cameras. This evidence builds a physics-based narrative that the defense can't easily challenge. Time is critical: after two weeks, degraded evidence becomes disputed and expensive to reconstruct.

California follows pure comparative negligence. If you're 20 percent at fault and the truck driver is 80 percent at fault, you recover 80 percent of damages. There's no bar to recovery even if you're partially at fault—unlike many other states, making California favorable for truck accident plaintiffs. Damages in truck accident cases often exceed $1 million because of injury severity. Medical care for spinal cord injuries, traumatic brain injuries, or multiple fractures can cost $5 million to $20 million over a lifetime. Lost wages, pain and suffering, and ongoing treatment are calculable. A seasoned commercial truck attorney in Los Angeles will hire a life care planner to project costs over decades, not just immediate medical bills. Trucking companies budget for settlements in the millions. Your attorney's job is to make clear that the plaintiff's damages justify a settlement at the high end of that range, not a low-ball insurance offer.
