What California law says after a motorcycle accident

Who may bring a wrongful death claim in California

When a collision results in death, California law allows specific family members to bring a wrongful death claim. The categories are defined by statute and generally include a surviving spouse or domestic partner, children, and, where there is no surviving spouse or issue, others who would be entitled to the property of the person who died. Certain dependents, including a putative spouse, stepchildren, or parents who were financially dependent, may also qualify.

A wrongful death claim compensates surviving family members for their own losses, including financial support, funeral and burial expenses, and the loss of the companionship, guidance, and society the person provided.

A separate claim, called a survival action, covers losses the person themselves sustained before death, such as medical expenses and lost earnings. California law changed here. For survival actions filed on or after January 1, 2026, damages for the decedent’s own pain, suffering, or disfigurement are no longer recoverable. Cases filed before that date are not affected, and different rules can apply in elder abuse matters.

Eligibility depends on family circumstances, filing deadlines are strict, and the damages available depend in part on when a case is filed.

Motorcycle collisions and California law

California expressly recognizes lane splitting, the practice of a motorcycle riding between rows of stopped or slow moving vehicles travelling in the same direction, in Vehicle Code section 21658.1. A rider who was lane splitting is not automatically at fault for a resulting collision. As in any collision, the question is what each party actually did and whether it was reasonable under the conditions.

California sets no legal speed limit and no speed differential for lane splitting. Figures that circulate widely, such as riding no more than ten miles per hour faster than surrounding traffic, come from a safety guidance document that was withdrawn more than a decade ago and were never part of the law. The California Highway Patrol publishes safety tips rather than numeric rules, and riding on the shoulder is not lane splitting and is not lawful.

California also requires every motorcycle rider and passenger to wear a helmet meeting federal safety standards, and the helmet must be properly fastened and correctly sized.

Motorcycle cases carry a practical difficulty that does not appear in other collisions. Riders frequently face an assumption that they were speeding, weaving, or riding recklessly, regardless of what the evidence shows. That assumption can appear in early reporting, in an insurer’s evaluation, and later in a jury’s thinking. Physical evidence, scene measurements, and independent witnesses often matter more in these cases than in a routine collision.
