California became the first state in the U.S. to formally legalize lane splitting when Gov. Jerry Brown signed Assembly Bill 51 in August, according to the Los Angeles Times.
The law, which goes into effect Jan. 1, defines the practice as a motorist driving a two-wheeled motorcycle between rows of stopped or moving vehicles. It also authorizes the California Highway Patrol to develop educational guidelines on lane splitting to help ensure the safety of all motorists.
CHP would have to consult with specified safety agencies and organizations in order to craft the guidelines for motorcycle lane splitting.
