Finally! California Highway Patrol Issues Lane Splitting Guidelines

California riders have known for a long time that lane splitting is legal in California. Many riders – especially moto commuters – cite lane sharing as one of the big reasons riding is awesome. But many folks have long seen lane splitting as a gray area. No more – the CHP has issued official lane splitting guidelines!

Lane splitting in a safe and prudent manner is not illegal in the state of California. The term lane splitting, sometimes known as lane sharing, filtering or white-lining, refers to the process of a motorcyclist riding between lanes of stopped or slower moving traffic or moving between lanes to the front of traffic stopped at a traffic light.

Motorcyclists who are competent enough riders to lane split, should follow these general guidelines if choosing to lane split.

  1. Travel at a speed that is no more than 10 MPH faster than other traffic – danger increases at higher speed differentials.
  2. It is not advisable to lane split when traffic flow is at 30 mph or faster – danger increases as overall speed increases.
  3. Typically, it is more desirable to split between the #1 and #2 lanes than between other lanes.
  4. Consider the total environment in which you are splitting, including the width of the lanes, size of surrounding vehicles, as well as roadway, weather, and lighting conditions.
  5. Be alert and anticipate possible movements by other road users.

The Four R’s or “Be-Attitudes” of Lane Splitting:
Be Reasonable, be Responsible, be Respectful, be aware of all Roadway and traffic conditions.

The guidelines are similar to those adopted by many moto commuters. Check out the full California lane splitting guidelines, or download the lane splitting quick guide (PDF).

Big thanks to everyone who pushed for so long to make this happen. As noted in the announcement thread on BARF, “Its been a long time coming. Its taken a lot of arm twisting, arguing, and frustration. But we have taken a huge leap forward.”
