Lane

In road transport, a lane is part of a roadway that is designated to be used by a single line of vehicles to control and guide drivers and reduce traffic conflicts. Most public roads (highways) have at least two lanes, one for traffic in each direction, generally separated by lane markings. On multilane roadways and busier two-lane roads, lanes are generally designated with road surface markings. Major highways often have two multi-lane roadways separated by a median.
