High-occupancy vehicle lane

A high-occupancy vehicle lane is a restricted traffic lane reserved at peak travel times or longer for the exclusive use of vehicles with a driver and one or more passengers, including carpools, vanpools, and transit buses. The normal minimum occupancy level is 2 or 3 occupants. Many jurisdictions exempt other vehicles, including motorcycles, charter buses, emergency and law enforcement vehicles, low-emission and other green vehicles, and/or single-occupancy vehicles paying a toll. HOV lanes are normally created to increase average vehicle occupancy and persons traveling with the goal of reducing traffic congestion and air pollution, although their effectiveness is questionable.
Regional and corporate-sponsored vanpools, carpools, and rideshare communities give commuters a way to increase occupancy. For places without such services, online rideshare communities can serve a similar purpose. Slugging lines are common in some places, where solo drivers pick up a passenger to share the ride and allow use of the HOV lane. High-occupancy toll lanes have been introduced in the United States to allow solo driver vehicles to use the lane on payment of a variable fee, which usually varies with demand. Motorcycles are permitted in HOV lanes for safety reasons.
