A bicycle with two chevrons above it, painted in the lane.
Also known as: Shared lane marking, Shared roadway bicycle marking, Bike with chevrons, Sharrow
A sharrow marks a lane that cyclists and drivers share and indicates where a cyclist should ride — usually further out than a cyclist would choose. It gives cyclists no space of their own, which is why its safety benefit is contested rather than established.
Marks a traffic lane shared between cyclists and motor vehicles and indicates the lateral position a cyclist should take.
Contexts: Public information
Positions cyclists away from the door zone of parked cars, which is the specific hazard the marking's placement addresses.
Contexts: Public information
Has a contested safety record: studies have found little or no benefit compared with unmarked shared lanes, and some have found worse outcomes than dedicated infrastructure.
Research findings on sharrow effectiveness conflict. This entry records that the evidence is mixed rather than asserting the marking is or is not effective.
