  • Getting In/Out

    Bay Area Express Lanes have sections where access into or out of the lane is restricted (separated with double white lines) and sections where it is unrestricted (separated with a dashed white line).

  • Enforcement

    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.
