What You Need To Know

  • How Express Lanes Work

    A few rules are lane-specific, so learn how each express lane works: 580, 680, 880, SR-237

    On all express lanes, drivers must have FasTrak, and carpools must have a FasTrak Flex toll tag in the vehicle set to the 2 or 3+ position to get carpool toll discounts. 

    All lanes operate 5 AM to 8 PM.

    Am I Toll Exempt?

    Motorcycles and vanpools travel toll free on all Bay Area Express Lanes with a FasTrak Flex toll tag set in the 3+ position. On the I-680 and I-580 Bay Area Express Lanes, 2-person carpools are toll free, while on I-880 and SR-237 2-person carpools pay half-price tolls with a FasTrak Flex toll tag set in the 2 position. See "For Carpools" and this video about FasTrak and Express Lanes. 

    Solo-driver clean air vehicles travel toll-free or pay half-price tolls depending on the express lane, but eventually solo-driver clean air vehicles will pay half-price tolls on all Bay Area Express Lanes. See "For Clean Air Vehicles."

    See this table for an at-a-glance view of each lane's tolling policies. 

  • Getting In/Out

    Bay Area Express Lanes have sections where access into or out of the lane is restricted and sections where it is unrestricted.

    Unrestricted sections are marked with dashed lines separating the express lane from regular traffic, and cars can enter or exit the express lanes in these sections.

    Restricted sections are marked with double white lines. Crossing double white lines is a traffic violation. If you are in a section with double white lines, highway signs explain where to exit the express lane to access highway exits.

  • Pricing and Signs

    The price to use the lane goes up or down every few minutes depending on traffic. Learn more

    • Signs show one or two destinations and the price to travel to each.
    • You are guaranteed the zone prices shown when you get in the lane, even if they change down the road.
    • Depending on where you get out of the lane and the lane's specific tolling rules, you pay either the top price, the bottom price or a price in between.
    • Your monthly FasTrak® statement will show the start and end point of each express lane trip and the price you paid.
    • The pricing signs on some express lanes may occasionally display “HOV ONLY” instead of a price. This indicates the lane is too crowded and does not have room for toll-paying vehicles to enter.
  • A CHP officer issuing a citation to a driver in vehicle pulled over from the I-680 Contra Costa express lanes.


    The California Highway Patrol (CHP) performs enforcement for all Bay Area Express Lanes. CHP enforces all laws within the California Vehicle Code while patrolling Bay Area Express Lanes, including:

    • Carpool occupancy requirements
    • Clean air vehicle requirements
    • Proper mounting of valid license plates
    • Illegal lane and buffer crossing
    • Proper mounting of a valid FasTrak® toll tag
    • Proper switch position setting on a FasTrak Flex® toll tag

    Express lanes have automated toll enforcement like at Bay Area bridges*. License plate cameras identify vehicles in the express lane without a valid FasTrak® toll tag, and FasTrak sends the registered vehicle owners violation notices for the toll amount and penalties. This helps to make sure express lane users follow the rules.

    *Exception is I-680 Sunol express lane.
