High Occupancy Vehicle (HOV) & Express Lanes

HOV lanes are traffic lanes set aside for vehicles with a minimum number of occupants. HOV lanes shorten commute times for carpoolers, but they also shorten commute times for everyone else on the road, by reducing the volume of traffic. HOV restrictions and even the direction of travel in these lanes may change depending on the day and time. Some HOV lanes are open to hybrid vehicles and/or motorcycles that don't carry the minimum number of riders. For the most up-to-date information about rules and hours for each system, follow the links provided under "HOV Lanes in Virginia" and "HOV Lanes in Maryland," below.

Express lanes are toll-free for carpoolers, but also allow vehicles that don't meet the occupancy requirement, charging a toll.
