Lane splitting is not legal in California (even though CHPs look the other way), but that may change soon
Proposal would make California the only state where this motorcycle lane splitting is allowed—and regulated by law.
Say you’re taking the freeway at rush hour, with traffic backed up in front, behind and to the sides, and just as you start toying with the radio a Harley goes howling by your left side, in the space between your car and the next lane over. That’s lane splitting, and even more surprising than the unexpected motorcycle is that the act is permitted in California. That isn’t quite the same thing as the practice being legal, and most states prosecute lane splitting even where there is no law explicitly against it. California is the only state where the police and the C.H.P. don’t go after people who do it. That could change soon, as the California legislature is considering a bill that would make California only state where lane splitting is legal.
