A lane is a longitudinal part of a roadway intended to accommodate a line of moving vehicles. A roadway may contain one or several lanes for traffic travelling in the same or opposite directions.
Lanes are commonly separated by continuous or broken road markings. Traffic signs, lane arrows and lane-control signals may indicate which vehicles may use a lane, which direction traffic must follow or whether a lane is open or closed.
