Motorcycle Lane-Splitting Could Soon Be Legal in California

Motorcycle lane-splitting _ the rush-hour time saver for bikers that enrages many drivers _ may be poised for legalization.

California would be the first state to sanction the traffic-evading tactic, already widespread on traffic-choked freeways of Los Angeles. The state Assembly is expected to approve the legislation as soon as this week, and supporters believe it will clear the Senate as well.

The measure would allow motorcycles to travel between cars at speeds up to 15 mph faster than the flow of traffic, up to a speed of 50 mph.

The bill's legislative backers cite studies showing the practice is safer than trapping bikers behind cars, which leaves them vulnerable to more serious rear-end collisions. But their proposal has riled both detractors and supporters.

"Lane-splitting is inherently dangerous," said Thomas Freeman, a passionate opponent of the practice who said his opposition movement, hosted online at, has more than 1,000 members. While some motorcyclists applauded the action, the American Motorcyclist Association called for even less restrictive rules.

"We don't like this bill," said Nicolas Haris, the association's western states representative. "It goes a long way in the right direction, but it falls short."

Lane-splitting _ a common practice in European nations but illegal in all U.S. states _ has been a fuzzy topic in California. The state has never expressly forbidden or allowed it.

Technically neither legal nor illegal, the practice has had the tacit approval of the California Highway Patrol and the Department of Motor Vehicles.

Motorcycle industry veteran Bruce Steever _ who commutes on the 405 Freeway and invariably lane-splits during rush hour _ applauded the proposed legislation, restrictions and all.

"Those numbers make me happy," he said of the speed limits. "There needs to be a codified law."

The AMA's Haris, despite his organization's complaints with the bill's specific language and speed limits, said he hoped a new California law would inspire legislators in other states to adopt similar laws.

Legislative bodies in Washington, Oregon, Texas, Nevada and Tennessee have already considered, proposed or voted on lane-splitting laws. To date, none of the proposed legislation has passed.

The California bill, which has broad support, is being spearheaded by Democratic Assemblyman Bill Quirk. He co-authored the measure with Republican Tom Lackey, a former California Highway Patrol officer, and Democrat Kansen Chu, who became interested in the topic after a staffer's nephew was killed while lane-splitting at high speed.

The speed limits were determined with the help of the CHP and a safety study by University of California, Berkeley, professor Tom Rice.

That study, scheduled for public release soon, investigated 6,000 California motorcycle accidents _ 1,000 of them involving lane-splitting _ and concluded that legalizing the practice was safer than outlawing it, Quirk said.

"The study found that lane-splitting was safer, compared to being stopped in the traffic," Quirk said. "Oftentimes motorcyclists would get rear-ended. Motorists just don't see them."

The bill appears to have momentum. It passed the Assembly Transportation Committee with a vote of 13-1 and the Assembly Appropriations Committee by 16-1. It now faces a vote in the 80-member Assembly.

If it passes there, it would face a similar review and vote in the Senate before heading to the governor's desk for final approval.

Until recently, both the Highway Patrol and the DMV published guidelines for safe lane-splitting. But they removed the guidelines from their publications last year after opponents complained that the agencies appeared to endorse a practice that critics argued was not legal.

"The ambiguity gave riders the idea that they had a free ticket," Lackey said. "These parameters will alert all motorists to the safe practice of lane-splitting."
