Shared Lane Marking
A shared-lane marking or sharrow is a street marking installed at locations in Australia, Canada, and the United States. This marking is placed in the center of a travel lane to indicate that a bicyclist may use the full lane.
According to the US Manual on Uniform Traffic Control Devices, shared-lane markings are used to:
- Assist bicyclists with lateral positioning in a shared lane with on-street parallel parking in order to reduce the chance of a bicyclist’s impacting the open door of a parked vehicle;
- Assist bicyclists with lateral positioning in lanes that are too narrow for a motor vehicle and a bicycle to travel side by side within the same traffic lane;
- Alert motorists of the lateral location bicyclists are likely to occupy within the traveled way;
- Encourage safe passing of bicyclists by motorists; and
- Reduce the incidence of wrong-way bicycling.
The name sharrow was coined by Oliver Gajda, of the City and County of San Francisco Bicycle Program, and is a portmanteau of share and arrow.

“... perhaps there exists only one intelligence from which the world sublets, one intelligence toward which each person, from the depths of his individual body, directs his gaze, as in the theater where, though each has a seat, however, there is only one stage.... But if it we all shared the same intelligence, [Bergotte] would, upon hearing me express [my ideas], remember them, love them, smile at them....”
