What is HOV lane in US roads?

Answer:
HOV stands for High Occupancy Vehicles. There is a lane set aside on major highways within cities or that lead into cities that is for vehicles that have two or more people in the vehicle. This is designed to coerce people to carpool by giving them a lane that they won't get tied up in traffic in during rush hour. It helps keep the number of cars down on the road by people sharing the ride to work.
