Truck Accidents vs. Car Accidents — Why the Legal Claims Are Different

When a semi-truck or commercial vehicle is involved in a crash, everything changes. The injuries are more severe, the evidence is more complex, and the legal claims involve parties and regulations that don’t exist in a standard car accident case.

Why Injuries Are Worse

Physics. A fully loaded semi-truck weighs 80,000 pounds. A passenger car weighs 3,500 pounds. That’s a 23-to-1 weight ratio. In a collision, the car — and its occupants — absorb almost all the force. Truck accidents produce traumatic brain injuries, spinal cord injuries, crush injuries, and fatalities at far higher rates than car-on-car collisions.

I-10 — Arizona’s deadliest highway — carries massive truck traffic as a primary freight corridor. Many of the fatal crashes on I-10 involve commercial vehicles.

Multiple Liable Parties

In a car accident, the other driver is typically the only defendant. In a truck accident, potential defendants include the truck driver, the trucking company (under respondeat superior), the cargo loading company (if an improperly secured load caused the crash), the truck maintenance company, the truck or parts manufacturer (product liability), and the shipper or broker who hired the trucking company.

Federal Regulations

Trucking companies are subject to Federal Motor Carrier Safety Administration (FMCSA) regulations covering hours of service (preventing driver fatigue), vehicle maintenance and inspection requirements, drug and alcohol testing, driver qualification standards, and electronic logging device (ELD) requirements.

Violations of these regulations are powerful evidence of negligence — and they create liability for the trucking company, not just the driver.

Evidence Preservation Is Critical

Trucking companies know they face significant liability. They may begin “preserving” — or destroying — evidence quickly after a crash. Black box data, driver logs, maintenance records, and dispatch communications must be preserved through a spoliation letter sent immediately.
