California law uses pure comparative negligence in assigning responsibility in pedestrian accident cases. According to this standard, one party to an accident can be 100% liable, or the responsibility is split between two or more parties.
For instance, if a pedestrian is walking in a crosswalk and a driver strikes them, a court would likely find the driver 100% at fault.
On the other hand, a speeding, distracted driver may fail to see a pedestrian and hit them while that person was jaywalking. In this case, the driver and pedestrian may have shared liability. The injured pedestrian then receives damages minus their liability. For example, if a court rules the pedestrian 50% at fault, the award is just 50% of the damages.
