Motorcycle Accident Under California Law
Motorcyclists face disproportionate injury severity in accidents with passenger vehicles — no structural protection means motorcycle accidents produce traumatic brain injury, spinal cord injury, and road rash at rates far exceeding car occupant accidents. California's lane-splitting law under Vehicle Code Section 21658.1 is also unique nationally. Helmets are required under Vehicle Code Section 27803, and comparative fault arguments about helmet use are common defense tactics.
California personal injury law provides a robust framework for motorcycle accident victims. The governing legal standard depends on the type of injury: vehicle accidents proceed under negligence (with Vehicle Code violations establishing negligence per se); premises liability proceeds under the Rowland v. Christian (1968) duty of care; product liability proceeds under Greenman v. Yuba Power Products (1963) strict liability; and medical malpractice proceeds under MICRA's professional negligence standard with its specific damage caps and shorter statute of limitations.
California's pure comparative fault system from Li v. Yellow Cab Co. (1975) allows motorcycle accident victims to recover damages even if they were partly at fault. Recovery is reduced proportionally by the victim's fault percentage but not eliminated. California imposes no cap on economic or non-economic damages in non-malpractice personal injury cases.
Who Is Liable After a Motorcycle Accident
Liability in motorcycle accident cases depends on the specific facts and the legal theory governing the injury type. For vehicle accidents: the at-fault driver and their employer (if driving for work). For premises liability: the property owner, lessee, or other party who controlled the property. For product liability: the manufacturer, distributor, and retailer in the entire distribution chain. For medical malpractice: the licensed healthcare provider and potentially the healthcare facility. For workplace accidents: the employer's workers' compensation insurer (exclusive remedy against the employer) and third-party defendants whose negligence contributed.
"Within two years: An action for assault, battery, or injury to, or for the death of, an individual caused by the wrongful act or neglect of another."
Damages Available After a Motorcycle Accident
California motorcycle accident victims can recover: all past and future medical expenses (no cap); lost wages and lost earning capacity; property damage; non-economic damages (pain, suffering, emotional distress, disfigurement, loss of enjoyment of life) — uncapped in non-malpractice personal injury cases; and punitive damages under Civil Code Section 3294 when the defendant's conduct constitutes malice, oppression, or fraud. Medical malpractice non-economic damages are capped by MICRA at $470,000 (personal injury) and $650,000 (wrongful death) in 2026.
Statute of Limitations for Motorcycle Accident Claims in California
Two years from the date of injury under CCP Section 335.1 for most motorcycle accident claims. Medical malpractice: one year from discovery or three years from the act (CCP Section 340.5). Government entity claims: six-month administrative claim under Government Code Section 945.4. Minor victims: tolled until age 18 under CCP Section 352. Missing any applicable deadline permanently bars the claim.
Critical Evidence in Motorcycle Accident Cases
- Medical records from the date of injury — Create a contemporaneous medical record tying injuries to the incident; seek care the same day if possible
- Incident or police report — Official documentation of the event, the parties, and any witnesses
- Photographs — The scene, injuries, defective condition, or damaged product at the earliest possible opportunity
- Witness information — Names and contact information for all persons who saw the incident
- Insurance information — All potentially applicable policies from all potentially liable parties
- Prior incident records — Prior complaints, citations, inspections, or product recalls that establish the defendant's prior notice of the hazard
- Employment and wage records — Documentation of lost income from the date of injury forward
Frequently Asked Questions — Motorcycle Accident
Is lane-splitting legal in California and how does it affect liability?
Yes. California Vehicle Code Section 21658.1, effective January 1, 2017, authorizes motorcycle lane-splitting (riding between lanes of stopped or slow-moving traffic). Lane-splitting itself is legal, but the statute requires the motorcyclist to act in a safe and prudent manner. If a motorcyclist was lane-splitting at excessive speed or in unsafe conditions, comparative fault may reduce recovery. If the motorcyclist was lane-splitting lawfully and a car made an unsafe lane change into the motorcycle, the car driver is liable.
Do I have to wear a helmet in California?
Yes. California Vehicle Code Section 27803 requires all motorcycle riders and passengers to wear a properly fitted safety helmet. Defense attorneys routinely raise helmet-use as a comparative fault argument — arguing that a rider not wearing a helmet at the time of the accident contributed to their own head injuries. While failure to wear a helmet does not bar recovery, it can reduce the non-economic damages for head injuries.
What damages are available to a motorcycle accident victim?
All economic damages: emergency care, hospitalization, surgery, rehabilitation, assistive technology, and future medical costs. Non-economic damages: pain and suffering, emotional distress, disfigurement from road rash scarring, and loss of enjoyment of life — uncapped in California. Motorcycle accidents frequently produce catastrophic injuries with lifetime economic damages that exceed those in comparable passenger vehicle accidents.
Are motorcyclists protected the same as car drivers under California law?
Yes. California's pure comparative fault system applies equally to motorcyclists. The fact that someone chose to ride a motorcycle does not reduce their rights or create any additional comparative fault. However, defense attorneys routinely argue that motorcyclists assumed the risk of riding or that their riding conduct contributed to the accident — making evidence of the accident's actual cause essential.
What if a car's door opened into my motorcycle?
California Vehicle Code Section 22517 prohibits opening a vehicle door on the traffic side without first checking for approaching traffic. A car occupant who opens a door into a motorcyclist's path has violated CVC 22517, establishing negligence per se. 'Dooring' accidents cause serious injuries and are fully compensable.
How long do I have to file a motorcycle accident lawsuit?
Two years from the date of the accident under CCP Section 335.1. Government entity claims: six months under Government Code Section 945.4. Motorcycle accident physical evidence — the motorcycle's damage, road debris, skid marks — should be preserved and documented immediately.
