Lane splitting has been legal in California for about two years. Motorcycles are allowed to drive in between the spaces of cars and trucks on the road, without legal consequence.
With Assembly Bill 51 signed by Gov. Jerry Brown, lane splitting is now legally defined in California. Previously, the act of riding your motorcycle between two lanes to bypass congested traffic was left to the CHP officer to determine if the riding was dangerous or reckless. Many are hopeful that these guidelines will later be refined by CHP, enacted on Jan 1st, 2017 and will make the roads a safer place for all motorists including motorcyclists.
