PICKERINGTON, Ohio – California is on track to become the first state to formally recognize lane splitting as a legal maneuver for motorcyclists.
Assembly Bill 51, sponsored by Assembly members Bill Quirk and Tom Lackey, authorizes the California Highway Patrol to devise educational guidelines for splitting lanes “in a manner that would ensure the safety of the motorcyclist, drivers and passengers.”
The bill passed the Assembly 74-0 on Aug. 3, with six Assembly members not voting. The state Senate had earlier passed the bill 38-0. Gov. Jerry Brown is expected to the sign the bill when it reaches his desk.
The American Motorcyclist Association fully supports this legislation.
“We are extremely pleased that this bill received such overwhelming support in the Assembly,” said Wayne Allard, AMA vice president for government relations. “These guidelines will provide motorcyclists and motorists, alike, with the information they need to safely interact in traffic.
“At the same time, we hope that California will serve as an example to other states. Research shows that, done responsibly, lane splitting can reduce traffic congestion and reduce the likelihood of motorcyclists being struck from behind,” Allard said.
A.B. 51 defines lane splitting as “driving a motorcycle that has two wheels in contact with the ground between rows of stopped or moving vehicles in the same lane.”
The bill also requires the California Highway Patrol to consult with other agencies and organizations with an interest in road safety and motorcyclist behavior in developing the guidelines for responsible lane splitting.
Two state-sponsored studies conducted by the University of California Berkeley concluded that lane splitting is a relatively safe maneuver when both the motorcyclist and nearby drivers know the law and adhere to “safe and prudent” practices.
Lane-splitting riders were less likely to be rear-ended by another vehicle than were other motorcyclists, according to the studies. And lane-splitting motorcyclists involved in crashes were notably less likely than other motorcyclists in crashes to suffer head injury, torso injury or fatal injury than other motorcyclists.
The studies also found that there was no meaningful increase in injuries until traffic speed exceeded 50 mph and that speed differentials between lane-splitting motorcyclists and other traffic were not associated with changes in injury occurrence until the differential exceeded 15 mph.
Those findings closely align with lane-splitting guidelines posted on the California Highway Patrol website in 2013 and removed in 2014 after a complaint from one Sacramento resident, who argued that the Highway Patrol was, in effect, making law.
California is the only U.S. state where lane splitting is permitted. Current state law neither prohibits nor specifically allows the maneuver.
In many countries, lane splitting and filtering are normal practices for motorcyclists, Allard said. Particularly in the highly urbanized areas of Europe and Asia, motorcycle and scooter operators are expected to pass between conventional vehicles and advance to the front of the group.
