i found on DmV.org this Lane Splitting Although lane splitting (the act of moving between cars to the front of traffic) sparks all types of ire from motorists, it is legal in many states. And considering motorcycles are extremely vulnerable on the road, it is not a bad idea to get in the clear. That is what the tactic is designed to do in the first place―remove obstacles from riders, not get them to a place any quicker than one of their four-wheeled brethren. Of course, you will want to use extra caution moving to the front of the pack. The best thing you can possibly do to improve your traffic skills is to sign up for a Motorcycle Safety Foundation course. They offer classes in each state for both the novice and experienced rider. It didnt say what states were legal though. I was searching under ohio though. Will keep looking!
