A "Sharrow" is a road marking that indicates a shared lane for both bicycles and motor vehicles. It consists of a bicycle symbol with two upward arrows above it, signaling to drivers that they should expect cyclists on the road. Sharrows are often used in urban areas to promote safe coexistence between different types of road users. The purpose of sharrows is to enhance safety and awareness, encouraging cyclists to ride in a position that is visible to drivers. They also remind motorists to be cautious and respectful of cyclists' space. Sharrows are part of broader efforts to improve cycling infrastructure and promote sustainable transportation options like bicycling.
