I just recently transferred from Wisconsin to CA. Are there any California officers on here that can tell me the legality of lane splitting? So far I have been told it's legal, it's not legal, it's neither legal or illegal and finally, it not illegal, but if an officer wants to pull you over and write you up for illegal lane change, or unsafe passing, he pretty much can do so on a whim. I would like to know before I hit 101 on my bike. Thanks.
