If you travel on Interstate 66 Inside the Beltway 5:30 - 9:30 a.m. eastbound or 3 - 7 p.m. westbound, you need to have an E-ZPass or E-ZPass Flex funded and properly mounted in your vehicle. If you are an HOV-3+ driver, an E-ZPass Flex allows you to use the lanes free when switched to HOV mode. (Effective Dec. 5, 2022, this changed from two or more people to three or more people.)
With an E-ZPass, electronic tolls are paid by being deducted automatically from your pre-paid E-ZPass account. The E-ZPass you need on the I-66 Express Lanes Inside the Beltway depends on how you plan to travel.
If you drive alone on I-66 Inside the Beltway during Express Lane hours, you need to have a standard E-ZPass.
If there are three or more people in your vehicle (HOV-3+), an E-ZPass Flex allows you to use the lanes free when switched to HOV mode.
