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.

Beginning December 4, 2017, all lanes of I-66 inside the Beltway (I-495) are Express Lanes during morning or evening rush hour. All eastbound lanes (toward Washington) are Express Lanes from 5:30 a.m. to 9:30 a.m. All westbound lanes are Express Lanes from 3 p.m. to 7 p.m. At other times, all lanes are open to all drivers, without a toll or HOV restrictions. While restrictions are in effect, vehicles with at least two occupants and an E-ZPass Flex may use the Express Lanes for free. Solo drivers are charged a variable toll for using the lanes, and must have an E-ZPass or E-ZPass flex transponder.
