Lane splitting—defined by the California Department of Motor Vehicles as “passing other vehicles proceeding in the same direction within the same lane”—is a common practice amongMotorcyclist Lane Sharing on a California Highway motorcyclists. In fact, one study found that 80 percent of California motorcyclists regularly lane split on the freeway.

Despite its popularity, there are questions surrounding both the safety and legality of lane splitting, also known as lane sharing or filtering. Contrary to popular belief, lane splitting is actually legal in California. State law never specifically forbade the practice and, in 2016, Governor Jerry Brown signed AB 51 into law, giving the California Highway Patrol (CHP) the ability to develop lane splitting guidelines.

The guidelines include tips to help motorcyclists who engage in lane splitting to do so more safely, as well as safety advice for motorists. CHP tips for lane-splitting motorcyclists include:

  • Observe speed limits
  • Assume that you're not visible to motorists and passenger vehicle occupants
  • Stay out of other vehicles' blind spots
  • Wear protective gear that's as visible as possible
  • Split between the far left lanes, rather than between other lanes of traffic
  • Avoid lane splitting next to big-rigs, semi-trucks, 18-wheelers, buses, and other large commercial trucks

The CHP also offered the following tips for motorists:

  • Watch for motorcyclists and anticipate their possible movements
  • Check mirrors and blind spots, especially prior to turning or changing lanes
  • Signal before changing lanes or merging with traffic
  • Never intentionally block or impede a motorcyclist in a way that could potentially cause harm to the rider
