Sharrows are shared lane markings used on roads that are too narrow for bike lanes. Use them by riding straight through the arrow. Sometimes this means taking the full lane, and faster-moving traffic must change lanes to pass safely.
On roads with one lane in each direction, move over (when it is safe) to help approaching cars pass you safely. In wider lanes, sharrows give you a good distance from parked cars on one side and traffic on the other. In both cases, stay visible and alert! Be ready to safely and predictably stop, slow, or change lanes – just like you would do if you were in any other vehicle.
