While California is the only state in the country that allows lane-splitting, there had not been written guidelines on how to safely execute the polarizing practice that often pits motorcycles against cars and trucks,
The California Highway Patrol and other statewide traffic safety groups have created a set of written guidelines on motorcycle “lane-splitting,” the at-times hair-splitting maneuver that allows riders to legally pass vehicles in adjacent lanes by driving between them.
The guidelines say that motorcyclists can ride between two cars if there is room, but only at speeds no more than 10 miles-per-hour faster than the vehicles they’re passing. The motorcyclists should not attempt the move at full freeway speeds or in any traffic going faster than 30 mph.
“There is a need to acknowledge lane-splitting is being done in California, and a need to help people understand what is reasonable,” California Highway Patrol Sgt. Mark Pope said. “Until now, no one in authority has said how to do it safely.”
