San Francisco Motorcycle Accident Claims

San Francisco motorcycle claims are shaped by a street environment that is uniquely hostile to two wheels. The city’s cable-car tracks, embedded Muni rails, steep grades, and grooved or patched pavement create road-surface hazards that barely affect a car but can put a motorcycle down on its own, which raises a road-condition question no car claim faces. A road-surface hazard — embedded rail or streetcar tracks, grooved or broken pavement, gravel, or a dangerous roadway condition — affects a motorcycle far more than a car, and where a public entity created or failed to fix it, a dangerous-condition-of-public-property claim (Gov. Code section 835) can apply, carrying the shorter six-month Government Claims Act deadline. On top of that, the two usual battlegrounds still apply. Lane splitting is legal in California under Vehicle Code section 21658.1, and California is the only state to have expressly authorised it. Insurers routinely try to blame a rider simply for splitting, but the question is whether the rider was splitting reasonably for the conditions, not whether they were splitting at all. Speed differential, traffic flow and lane position are the facts that decide it. SF’s dense stop-and-go traffic makes splitting routine, and it is legal. The most common motorcycle collision is a car turning left across a rider’s path, and Vehicle Code section 21801 requires a left-turning driver to yield to oncoming traffic that is close enough to be a hazard. Drivers frequently say they “never saw” the motorcycle, which usually describes a failure to look rather than a defence. And the city’s tight intersections produce frequent left-turn collisions. Two financial realities shape the outcome: motorcycle injuries tend to be severe, and many at-fault drivers carry little insurance, so the rider’s own coverage often pays. Motorcyclists are disproportionately hurt by drivers with no or minimal insurance, so the rider’s own uninsured/underinsured motorist coverage is frequently the main source of recovery. UM/UIM is first-party coverage under Insurance Code section 11580.2 with its own notice requirements and deadlines, and underinsured coverage typically pays only the gap above the at-fault driver’s limits, so identifying every applicable policy early matters. On helmets: Unlike bicyclists, every motorcycle rider and passenger in California must wear a DOT-compliant helmet under Vehicle Code section 27803. If a helmet was not worn, an insurer may raise it as comparative fault for head injuries, but it does not bar the claim, it has no bearing on non-head injuries, and under pure comparative negligence it would at most reduce recovery. Pure comparative negligence applies, so any genuine rider fault reduces rather than bars recovery. A road-defect claim against the City or a transit agency runs on the six-month deadline, while an ordinary claim runs on two years. Civil cases are filed in San Francisco County Superior Court.
