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.
Note:These general guidelines are not guaranteed to keep you safe.
Lane splitting should not be performed by inexperienced riders. These
guidelines assume a high level of riding competency and experience.
Every rider has ultimate responsibility for his or her own decision
making and safety. Riders must be conscious of reducing crash risk at
all times.
