What to Do After a Truck Accident in California

Why Truck Accidents Are Different from Car Accidents

A collision with an 80,000-pound commercial truck is fundamentally different from a car accident in several ways. First, the injuries are typically more severe — spinal cord injuries, traumatic brain injuries, and fatalities are far more common. Second, there are more potential defendants: the truck driver, the trucking company, the cargo owner, the truck manufacturer, and the maintenance company may all share liability. Third, federal regulations govern commercial trucking — the FMCSA's hours-of-service rules, driver qualification standards, and vehicle inspection requirements create a detailed paper trail that your attorney can use to prove negligence. Fourth, critical evidence — electronic logging device (ELD) data, dashcam footage, and black box data — can be overwritten or deleted within days. Speed is essential.

Step 1: Preserve Critical Evidence Immediately

The most important step after a California truck accident is preserving evidence before it disappears. Electronic logging device (ELD) data records the driver's hours of service and can prove fatigue — but it may be overwritten within 30 days. Event data recorders (black boxes) capture speed, braking, and steering data in the seconds before impact — but they can be overwritten too. Dashcam footage from the truck or nearby businesses may be recorded over within days. Your attorney should send a litigation hold letter to the trucking company within 24–48 hours of the accident demanding preservation of all electronic data, maintenance records, driver logs, and communications. Do not wait.

Step 2: Get Medical Treatment and Document Everything

Seek emergency medical treatment immediately, even if you feel okay. Adrenaline can mask serious injuries, and symptoms of traumatic brain injury, internal bleeding, and spinal injuries may not appear for hours or days. Keep records of every medical visit, prescription, and out-of-pocket expense. Photograph your injuries at regular intervals — bruising and swelling often worsen in the days after the accident. Keep a pain journal documenting how your injuries affect your daily life. This documentation directly supports your damages calculation.

Step 3: Identify All Potential Defendants

California truck accident cases often involve multiple defendants: (1) The truck driver — for negligent driving, fatigue, distracted driving, or DUI. (2) The trucking company — for vicarious liability, negligent hiring, negligent supervision, or failure to maintain the vehicle. (3) The cargo owner or shipper — if improperly loaded or secured cargo caused the accident. (4) The truck manufacturer — if a defective component (brakes, tires, steering) contributed to the crash. (5) A maintenance company — if negligent repairs caused a mechanical failure. Identifying all defendants is critical because it determines the total available insurance coverage — which can be dramatically higher than a single-defendant case.

FMCSA Regulations: Your Most Powerful Evidence

The Federal Motor Carrier Safety Administration (FMCSA) regulates commercial trucking in California with detailed rules that create a powerful evidence framework. Hours-of-service regulations limit how many hours a driver can operate without rest — violations are evidence of negligence per se. Driver qualification files must document the driver's license, medical certification, and driving history — gaps are evidence of negligent hiring. Vehicle inspection and maintenance records must be kept for 12 months — missing records are evidence of negligent maintenance. Drug and alcohol testing records are required after accidents — a positive test is powerful evidence. Your attorney will subpoena all of these records through the litigation process.

Carrier Insurance Coverage: Why Truck Cases Are Worth More

Under FMCSA regulations, commercial trucks operating in interstate commerce must carry minimum liability insurance of $750,000 (for general freight) to $5,000,000 (for hazardous materials). Many large carriers carry umbrella policies of $10 million or more. This is dramatically higher than the minimum $30,000/$60,000 required for California passenger vehicles (effective January 1, 2025 under AB 1107, raised from the prior $15,000/$30,000). Additionally, cargo owners, shippers, and leasing companies may carry their own policies. An experienced truck accident attorney will identify all available insurance coverage — not just the driver's policy — to maximize your recovery.

Key Takeaways

• Truck accident evidence (ELD data, black box, dashcam) can be deleted within days — your attorney must send a preservation letter immediately
• Multiple defendants (driver, carrier, cargo owner, manufacturer) mean multiple insurance policies and higher potential recovery
• FMCSA violations (hours-of-service, maintenance records, drug testing) are powerful evidence of negligence
• Commercial trucks must carry $750K–$5M in liability insurance — far more than car accident policies
• California's 2-year statute of limitations applies, but evidence preservation deadlines are much shorter
