http://www.americanmotorcyclist.com/asp/amaccess/laws/result.asp?state=oh bottom of the page. specifically says that lane splitting is "Not referenced in Administractive Code or Statutes" now with that being said, i do not agree with what the guys in the video were doing, nor do i split lanes at 80mph on I270. but if going up the shoulder to cut my driving time from 2 hours to 45 mins(personal experience going to school) or keeping someone who has a vandetta against bikers(also personal experience) from hitting me, you bet your ass im splitting.
