Do Not Use Sharrows as Cycling Facilities

Speedy driving lanes with sharrow markings are not safe
  • Jeff Speck


SHARROWS, OR SHARE-THE-ROAD MARKINGS, are biking symbols that are placed in a driving lane in order to inform cyclists and drivers alike that the lane is meant to serve both parties equally. They generally come in two forms, either placed in the center of a normal-width lane, or placed right-of center in a wide lane. In the former configuration, cyclists are meant to “claim the lane,” with drivers patiently cruising behind them. In the latter, cyclists are supposed to stay to the right, with drivers exercising caution in passing them. The potential for conflict in each of these scenarios is not hard to spot.
