Yes, lane splitting is legal in California under certain conditions. Lane splitting refers to the practice of a motorcycle riding between lanes of stopped or slow-moving traffic. In California, the California Vehicle Code (CVC) does not explicitly prohibit or authorize lane splitting, but it is recognized as a legal practice if done safely. In 2016, California became the first U.S. state to formally legalize lane splitting by passing Assembly Bill No. 51. The law provides guidelines for safe lane splitting and empowers the California Highway Patrol (CHP) to develop educational guidelines to promote rider safety. These guidelines include factors such as the speed of traffic, the speed of the motorcycle, and the width of lanes.
