California Lane Splitting Bill Signed Into Law

California┬ábecame the first state to legally recognize lane splitting, as Governor Jerry Brown signed A.B. 51 into law today. The bill does not outline guidelines or rules for lane splitting. Instead, it simply a) defines lane splitting as “driving a motorcycle, that has 2 wheels in contact with the ground, between rows of stopped or moving vehicles in the same lane, as specified”; and b) authorizes the California Highway Patrol (CHP) to “develop educational guidelines relating to lane splitting in a manner that would ensure the safety of the motorcyclist, drivers and passengers, as specified.”

It also requires that, in developing said guidelines, the CHP consult with agencies and organizations with “an interest in road safety and motorcyclist behavior.” These include, but are not limited to, the Department of Motor Vehicles, the Department of Transportation, the Office of Traffic Safety and “a motorcycle organization focused on motorcyclist safety.”

The bill was sponsored by Assembly members Bill Quirk (D-Hayward) and Tom Lackey (R-Palmdale).

Lane splitting has long existed in a legal gray area in California, being neither expressly prohibited nor allowed. The CHP developed guidelines in 2012, and posted them online and in the DMV’s Motorcycle Handbook, but a state employee lodged a complaint in 2014 that the guidelines were “underground regulations” that hadn’t gone through the proper legislative procedure, and so the CHP and DMV removed them.

A.B. 51 essentially clarifies that the CHP does in fact have the authority and permission to develop educational guidelines on lane splitting, and opens the door to further clarification and rules.

“This is great news for motorcyclists in California and throughout the country,” said Rob Dingman, president and CEO of the American Motorcyclist Association. “The California Assembly and the governor have taken a huge step in formally recognizing a practice that has been in use for decades.┬áLane splitting keeps riders safer by eliminating their exposure to rear-end collisions, and it helps ease congestion by effectively removing motorcycles from the traffic lanes.”

“We hope that other states will follow California’s lead on this issue,” Dingman said. “The AMA is here to support individuals, groups and legislators who want lane splitting made legal in their states, too.”

  1. Finally, something sensible to come out of California!
    I hope the other 49 States have the good sense to follow suit!

  2. I use the entire lane from left to right. If a large vehicle occupies the next lane to the right, I will occupy the farthest to the left of my lane as I pass. So there is no room for a motorcycle in my lane with me. But even though I may now be legally required to compromise my safety and allow simultaneous occupation with a motorcycle, I won’t do so with a passenger in the car.

    • when a driver occupies the entire lane, I just patiently wait till the adjacent vehicle moves along enough to allow me to pass .

      • And this post, by John, illustrates the difference between a mature, intelligent, responsible individual, and childish, immature, selfish behavior.
