Hit by a Commercial Truck in San Diego? Understand the Law.

Truck Accidents in San Diego

San Diego's position as a major Pacific port city and international border crossing makes it one of California's most truck-intensive metro areas — with commercial freight moving through the Port of San Diego, along I-5, I-8, and SR-905, and across the US–Mexico border daily, creating concentrated collision risk on corridors where large-truck crashes cause disproportionate injury.

The Port of San Diego and the nearby Otay Mesa commercial port of entry generate substantial drayage and long-haul truck volume on Interstate 5 and State Route 905. These corridors experience frequent large-truck rear-end collisions, jackknife incidents, and underride crashes — collision types where the size and weight disparity between a commercial vehicle and a passenger car produces severe injury outcomes. Trucks fully loaded to the federal 80,000-pound gross weight limit carry kinetic energy that no passenger vehicle is designed to absorb.

Inland distribution routes including Interstate 8 east toward El Centro and Interstate 15 north toward Riverside also see significant commercial vehicle volume. Mountain grades on I-8 near Alpine and the Laguna Mountains are locations where runaway truck incidents and brake-related crashes are historically elevated, due to the demands of sustained downhill braking on heavy freight vehicles.

Liability in San Diego truck accident cases frequently extends beyond the individual driver. Trucking companies bear vicarious liability for employed drivers acting in the scope of their duties, and may bear direct liability for negligent hiring, inadequate training, or failure to maintain vehicles in compliance with federal inspection standards under 49 C.F.R. Part 396. Shippers and cargo loaders may bear responsibility if improper loading contributed to cargo shift or vehicle instability. Vehicle and component manufacturers may face products liability exposure if a defective brake, tire, or coupling contributed to the crash.

The California Highway Patrol (CHP) enforces both state and federal commercial vehicle regulations on California highways. A CHP post-crash inspection that identifies hours-of-service violations, equipment defects, or weight violations can constitute significant evidence of carrier negligence in a civil case. Injured parties or their representatives may request CHP inspection records through the California Public Records Act.

California Law That Applies to Your Case

California applies pure comparative fault in truck accident cases, allocating damages among all responsible parties based on their percentage of fault. A jury may apportion fault among the truck driver, the trucking company, a negligent cargo loader, a defective parts manufacturer, and even the injured party — with each defendant responsible for their proportionate share of economic and non-economic damages.

Federal Motor Carrier Safety Administration (FMCSA) regulations establish minimum safety standards for commercial trucks in interstate commerce. Hours-of-service rules under 49 C.F.R. Part 395 limit drivers to 11 hours of driving within a 14-hour on-duty window and require a minimum 10-hour rest period. When a driver or carrier violates these rules and a crash results, California courts may treat the violation as negligence per se — meaning the violation itself establishes breach of duty without requiring further proof of unreasonableness.

California also imposes independent obligations on motor carriers through Cal. Veh. Code § 34501 and related CHP regulations, including mandatory pre-trip and post-trip vehicle inspections, driver qualification file maintenance, and drug and alcohol testing programs mirroring federal requirements. Carriers who fail to comply with these state-level obligations may bear direct liability separate from any driver negligence.

The two-year statute of limitations under Cal. Code Civ. Proc. § 335.1 applies to personal injury claims arising from truck accidents. Because critical evidence — electronic logging device (ELD) data, onboard event data recorder information, and surveillance footage — may be overwritten or deleted within days, early action to preserve evidence through a litigation hold notice to the carrier is an important step for injured parties.

Courts and Procedures in San Diego

Truck accident civil lawsuits in San Diego are filed in the San Diego Superior Court. Cases with damages exceeding $35,000 are brought in the unlimited civil jurisdiction division at the Hall of Justice. Because truck accident cases often name multiple corporate defendants and involve federal regulatory issues, they frequently qualify for complex case designation under Cal. Rules of Court, Rule 3.400, which assigns the case to a single judge for all purposes and provides a structured case management process.

Complex case designation is particularly significant in truck accident matters because it facilitates coordinated discovery across multiple defendants — the driver, the motor carrier, the vehicle owner, and potentially the cargo shipper. Early case management conferences allow the court to set phased discovery schedules and address the preservation of electronic evidence such as ELD data and onboard camera footage.

Standard unlimited civil cases in San Diego proceed through mandatory case management conferences within 180 days of filing, with trial typically assigned 18 to 24 months out for complex matters. The court's ADR program offers mediation, which is frequently used to resolve truck accident cases before trial given the number of insurance carriers and defendants typically involved.

What to Do After a Truck Accident in San Diego

1. Call 911 immediately. Request law enforcement and EMS. CHP typically responds to commercial vehicle crashes on state highways; SDPD responds to city street incidents. A crash report documents the truck's identification information and driver status at the scene.
2. Record the truck's identification information. Photograph the truck's DOT number (on the cab door), license plate, company name and USDOT number, and any trailer information. This identifies the carrier and triggers FMCSA record lookup.
3. Document the scene thoroughly. Photograph all vehicle positions, road and weather conditions, skid marks, cargo spill if any, and visible injuries. Video the full scene including surrounding road geometry before vehicles are moved.
4. Seek emergency medical care. UC San Diego Medical Center, Scripps Mercy Hospital, and Sharp Memorial Hospital are San Diego's major trauma centers equipped to treat serious injuries. Prompt evaluation links injuries to the crash date and initiates the medical record trail.
5. Do not repair or dispose of your vehicle. Vehicle damage evidence — including underride damage, contact patterns, and crush depth — is essential to engineering reconstruction. Preserve the vehicle until documented by an accident reconstructionist.
6. Notify your insurer. Report the crash to your own insurer per your policy obligations. Injured parties are not required to give recorded statements to the trucking company's insurer; doing so without legal guidance may be prejudicial.
7. Act quickly on evidence preservation. Electronic logging device data, onboard event recorder data, and fleet dashcam footage are routinely overwritten within days to weeks. A licensed California attorney can send a litigation hold letter to the carrier demanding preservation of all records.
8. Be aware of the two-year deadline. Cal. Code Civ. Proc. § 335.1 provides a two-year limitations period from the date of the truck accident. Government entity claims require a tort claim within six months.
