A bus lane is a designated space on the road that is solely reserved for the use of buses, coaches and other public transport vehicles. It allows these modes of transportation to travel more quickly and efficiently and can also help to reduce traffic congestion in densely populated areas. Synonyms for a bus lane include transit lane, priority lane, high occupancy vehicle (HOV) lane, and exclusive lane. These lanes are essential for maintaining a smooth flow of traffic in urban areas and also play a significant role in promoting sustainable public transportation options.
