A high-occupancy vehicle lane (also known as anHOV lane, carpool lane, diamond lane, 2+ lane, and transit lane or T2 or T3 lanes in Australia and New Zealand) 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....

Maybe other members can see some good use of it and will have other opinion
