Riding to the right of and parallel to a line of motor traffic to the left within a wide travel lane, but not in the edge hazard zone. This is a subset of edge behavior that is relatively safer than riding in the edge hazard zone or near the edge of a lane that is not wide enough for side by side operation. Normally lane sharing is used only in lanes wide enough for safe side by side operation of a motor vehicle and a bicycle, but it can be used in narrower lanes when passing is safe, to encourage passing.
Executive Director, American Bicycling Education Association
Through two decades of bicycling, I observed many close calls and conflicts as an individual transportation cyclist as well as a recreational group rider. Studying the behavior of both cyclists and motorists, I became convinced that the greatest challenge facing American bicycling is lack of education, coupled with the destructive belief system Americans have developed about our roads.
It has become my mission to correct this problem and empower individual bicyclists to ride with the confidence and skills to reach any destination by bike. I believe we can transform our traffic culture, through education and social marketing, into one which recognizes that roads are for all people, not just the ones driving cars.
