California is the only state in the U.S. where lane splitting—riding a motorcycle between lanes of stopped or slow-moving traffic—is legal. While it can reduce commute times and ease traffic congestion, it also introduces questions about fault and safety when accidents happen. At ANTN Law, we help injured motorcyclists navigate these complex cases and secure the compensation they’re owed.
Although lane splitting was formally recognized under Assembly Bill 51, the law leaves room for interpretation. The California Highway Patrol (CHP) has issued safety guidelines, not strict laws, making it crucial for riders to follow best practices to avoid liability:
Speed Differential: Don’t exceed the speed of surrounding traffic by more than 10 mph
Traffic Conditions: Lane splitting is safer in traffic moving at 30 mph or less
Lane Choice: Lane splitting is recommended between the far-left lanes (#1 and #2)
Visibility & Space: Avoid splitting near large trucks or in blind spots
Understanding and following these guidelines isn’t just about safety—it can influence fault determination in the event of a crash.
California uses a comparative negligence system. That means if both the motorcyclist and the other driver share blame, liability (and compensation) is divided proportionally.
Was the motorcyclist following CHP safety guidelines?
Did the other driver change lanes without signaling?
Were road or weather conditions contributing factors?
Was the rider visible and riding predictably?
ANTN Law has helped many riders prove that even while lane splitting, they were operating safely—and deserve full or majority compensation.
One of our clients, a motorcyclist in Los Angeles, was lane splitting in heavy traffic when a driver veered into his lane without signaling. Despite attempts by the insurer to shift blame onto the rider, ANTN Law demonstrated through helmet cam footage and traffic expert testimony that the driver acted negligently. The result? A six-figure settlement that covered surgery, lost wages, and ongoing therapy.
