Rear-Ended by a Commercial Truck: Overview Under California Law

Being rear-ended by a commercial truck creates both higher injury severity — due to the extreme mass differential — and a richer liability landscape than a passenger vehicle rear-end. FMCSA regulations apply to the truck driver and carrier: hours-of-service limits (49 CFR Part 395), ELD records, pre-trip brake inspection requirements (49 CFR Part 396), and minimum insurance of $750,000 (49 CFR Section 387.9).

California rear-end collision law is governed primarily by Vehicle Code Section 21703 (following too closely), the rebuttable presumption of fault against the rear driver, and California's pure comparative fault system from Li v. Yellow Cab Co. (1975). The victim's recovery encompasses all economic damages (medical expenses, lost wages, property damage) and non-economic damages (pain and suffering, emotional distress) without any cap under California personal injury law.

CVC 21703 and the Presumption of Fault

California Vehicle Code Section 21703 prohibits following another vehicle more closely than is reasonable and prudent. In a rear-end collision, a rebuttable presumption arises that the following driver violated this statute. The following driver must produce evidence to rebut the presumption — typically a sudden, unexpected stop by the lead driver or an emergency — failing which the presumption stands and establishes the following driver's negligence.

"The driver of a motor vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard for the speed of such vehicle and the traffic upon, and the condition of, the roadway."

Comparative Fault in Rear-Ended by a Commercial Truck Cases

California's pure comparative fault system allows recovery even if the rear-end victim was partly at fault — for example, by stopping abruptly or driving with non-functional brake lights. The victim's recovery is reduced proportionally by their fault percentage but is not eliminated. In multi-vehicle rear-end cases, Proposition 51 (Civil Code Section 1431.2) allocates non-economic damages among defendants proportionally while maintaining joint and several liability for economic damages.

Damages Available After a Rear-Ended by a Commercial Truck

California rear-ended by a commercial truck victims can recover: all past and future medical expenses; lost wages and earning capacity; vehicle property damage including diminished value; non-economic damages (pain, suffering, emotional distress, loss of enjoyment of life) — uncapped in California; and punitive damages under Civil Code Section 3294 when the rear driver's conduct constitutes malice (DUI, intentional brake-check, reckless speed).

Statute of Limitations

Two years from the date of the accident under CCP Section 335.1. Government entity claims: six months under Government Code Section 945.4. Minor victims: tolled until age 18 under CCP Section 352. Missing these deadlines permanently bars the claim.

Critical Evidence in Rear-Ended by a Commercial Truck Cases

  • Police report — Establishes the official record of the accident, the parties, and any citations issued for following too closely or other violations
  • Medical records from the accident date — Emergency department or urgent care records creating a contemporaneous medical record tied to the collision
  • Photographs — Both vehicles, the accident scene, skid marks (or absence thereof), and all visible injuries
  • Dashcam footage — From your vehicle or others at the scene; establishes the following driver's behavior before impact
  • Witness information — Names and contact information for all witnesses at the scene, including bystanders
  • Event data recorder (EDR) data — Speed, braking, and throttle data in the seconds before impact; request preservation immediately for commercial vehicles
  • Cell phone records — Obtainable through discovery to establish distracted driving if the rear driver was texting

Frequently Asked Questions — Rear-Ended by a Commercial Truck

Is a commercial truck driver automatically at fault for rear-ending my car?

Under CVC Section 21703 and FMCSA following-distance regulations, there is a strong presumption of negligence against a commercial truck driver who rear-ends a passenger vehicle. The truck driver and motor carrier must demonstrate a sudden emergency or mechanical failure to rebut this presumption. The FMCSA-required ELD records, EDR data, and maintenance history are critical evidence.

What insurance minimum applies when a commercial truck rear-ends me?

FMCSA regulations under 49 CFR Section 387.9 require minimum liability insurance of $750,000 for commercial vehicles carrying general freight in interstate commerce. This is far above California's personal auto minimums of $30,000/$60,000. Many large carriers maintain policies well above this minimum plus umbrella coverage.

What is an ELD and why does it matter in a truck rear-end case?

An electronic logging device automatically records the truck driver's hours of service, driving time, location, and vehicle speed. In a truck rear-end accident, ELD records establish whether the driver violated hours-of-service limits, was fatigued, and the vehicle's speed history. A written preservation demand must be sent to the carrier immediately after the accident.

Can I sue both the truck driver and the trucking company?

Yes. The motor carrier is vicariously liable for its driver's negligence under respondeat superior. The motor carrier also faces direct negligence claims for FMCSA compliance failures — including inadequate pre-trip brake inspections and dispatching a fatigued driver. Multiple defendants improve the chances of full recovery.

Why are injuries worse when a truck rear-ends a passenger vehicle?

A loaded semi-truck weighs up to 80,000 pounds compared to 3,000-4,000 pounds for a passenger vehicle. The kinetic energy differential means that even a relatively low-speed truck rear-impact produces catastrophic structural damage and severe occupant injuries. Cervical spine injuries, traumatic brain injury, and spinal cord injury are far more common when the rear-end vehicle is a commercial truck.

How long do I have to sue after being rear-ended by a truck?

Two years from the date of the accident under CCP Section 335.1. ELD records, EDR data, and carrier dispatch communications are subject to deletion under carrier retention policies — a written preservation demand must be sent immediately. Government entity truck claims: six months under Government Code Section 945.4.
