Oregon bill would allow lane splitting by motorcyclists By Chris Lehman, oregonlive.com Share: Motorcyclists could drive between lanes of traffic in certain conditions under a bill scheduled for a vote Wednesday in the Oregon Senate. Called “lane splitting” or “lane filtering,” the idea is to give motorcycles the ability to slip between slow or stopped vehicles. Senate Bill 574, sponsored by a bipartisan group of urban and rural lawmakers, lays out some very specific requirements. First, it can only happen on roads with two or more lanes of traffic heading in the same direction. Surrounding traffic has to be traveling at ten miles per hour or slower before the motorcyclist can move between the lanes.
