Lane Splitting, the maneuver to cut between cars, became legal yesterday Friday August 18 after California governor Jerry Brown signed Assembly Bill 51 into law . Until now lane splitting was not legal or illegal, just a tolerated riding practice. Since 2013, the California Highway Patrol (CHP) just had relatively vague guidelines for lane-splitting. They said that bikers should not lane-split when traffic is going faster than 30 mph and should stay within 10 mph of the speed of traffic while between lanes.
The CHP has now to develop precise guidelines for the motorcyclists who delight in waving between cars to go ahead of traffic. The new guidelines will take away the past subjectivity of police officers deciding if lane-slotting was or not reckless driving.
