The space beside a car that is within striking distance of its door—typically 4ft from the car. The hazard zone of a line of parked cars should be considered to be at least 5ft. A bicyclist should ride far enough away to avoid being struck, but also to avoid being startled into swerving.
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.
