Traveler Options

As of Dec. 5, 2022, HOV Rules on I-66 Have Changed – Form Your HOV-3+ Carpool Now and Earn Up To $366 Per Person

As part of transforming I-66 to move more people and provide new travel options, High Occupancy Vehicle (HOV) rules on I-66 have changed. The switch went into effect on Dec. 5, 2022. Vehicles will need to have three or more occupants to qualify as HOV on I-66 and travel the express lanes without paying a toll. This change from HOV-2+ to HOV-3+ will apply across the entire I-66 corridor including the 22.5-miles of 66 Express Lanes located outside the Beltway, as well as the nine miles of 66 Express Lanes located inside the Beltway between I-495 and Route 29 in Rosslyn, which operate on weekdays during peak periods in peak commute directions, and the section of I-66 between Haymarket and Gainesville.

VDOT and the region’s Commuter Connections program have partnered to offer an incentive of up to $366 per person for new HOV-3+ carpools traveling in the I-66 corridor. The program is available now (sign up by Feb. 28, 2023) and will pay each participant a cash reward following three months of carpooling, regardless of whether they are a driver or passenger and whether it is a new carpool or an existing HOV-2+ carpool adding a third person. Learn more about the Pool Rewards program and sign up here.

This HOV change will establish consistent requirements across Northern Virginia’s Express Lanes network on I-66, I-95, I-495, and I-395, providing seamless, reliable travel for carpool, vanpool, and commuter bus travelers. Learn more about this HOV change here.

Taking the bus on I-66 during construction is more affordable with half-price bus fares.

Half-price fares are available on OmniRide I-66 bus routes from Gainesville and Manassas. New bus service launched Dec. 12, 2022, from the new Balls Ford lot to Dulles Corridor/Herndon/Reston.

Vanpooling with other commuters traveling on I-66 is more affordable and a great way to reduce stress on your commute! Riders in new vanpools of five or more riders pay only $150 per month for the first 12 months. Keep in mind that vanpool incentives will only be available for 90 days after the opening of the express lanes.

The Transform 66 Vanpool Program can make your commute on I-66 much easier. Find out how by contacting our Transform 66 vanpool experts to locate or join a vanpool on I-66 Outside the Beltway. Contact Theresa McMullin by phone: 703-969-7712, or email: theresa.mcmullin@transform66vanpool.org.



The region’s Commuter Connections’ Pool Rewards program usually provides up to $130 for new carpoolers through a trip-tracking process. Commuters who start a three-person carpool on I-66 by Feb. 28, 2023, can receive an additional $236 cash reward for a total of $366 per person after three months. Get started!



Avoid commuting altogether by working remotely or teleworking. Check with your employer to learn about telework options. For employers interested in establishing a telework program, Virginia’s Telework!VA program provides technical advice, on-site assistance, and financial incentives. 


All travel options are eligible for Commuter Connections’ Guaranteed Ride Home program. 

Local Support
Local governments across Virginia have their own long-standing programs and expertise helping employers and residents with their commutes. In Northern Virginia, that includes Arlington, Fairfax, Loudoun, and Prince William counties.

HOV Changes on I-66
Changes to HOV regulations on I-66 have been planned for years as part of the effort to move more people in the I-66 corridor. The change in HOV designation from HOV-2+ to HOV-3+ on I-66 Outside the Beltway from University Boulevard in Gainesville to I-495 (Capital Beltway) was approved by the Virginia Commonwealth Transportation Board (CTB) in July 2016. This change supports the public interest by reducing the number of vehicle miles traveled, reducing travel times, increasing speeds in the express lanes and general-purpose lanes, and complying with the federal Clean Air Act Amendment of 1990. This HOV-3+ policy is consistent with the National Capital Region’s Transportation Planning Board policy since 2010 to increase the occupancy requirements on HOV lanes in the region to HOV-3+.
