How to Install Your Sticker Transponder

  1. Clean Interior Windshield

    Clean and dry the inner surface of the windshield where the sticker transponder will be placed.

  2. Carefully Peel the Sticker

    Carefully peel the backing from the sticker. Avoid touching the adhesive and keep the sticker as flat as possible. Bending it may break the antennae.

  3. Placing the Sticker

    Place the sticker transponder in the lower left-hand corner or lower right-hand corner of the inside of the windshield. Or, place it behind the rearview mirror on the inside of the windshield (Consider visual aesthetics from inside and outside of the vehicle when choosing the location.)


    Do not move or adjust a sticker transponder once it has been installed. It will break and become unusable.

  4. Update Your Account

    Make sure all vehicle license plates are registered to your account. Log in to your account.

Switchable FasTrak Transponder

Switchable FasTrak transponders (sometimes called FasTrak Flex®) have a small black switch that can be moved to indicate the number of occupants in the vehicle. It is the driver's responsibility to indicate the number of occupants in the vehicle by moving the switch to the appropriate setting (1, 2, 3+). This should be done prior to starting each trip.

Toll-free travel for qualifying carpools and other eligible vehicles is often only available to drivers who have a switchable FasTrak transponder; drivers with standard FasTrak transponders pay the full toll regardless of the number of occupants in the vehicle.

Drivers with sticker transponders pay the full toll regardless of eligibility.

A switchable transponder can be obtained by opening up an account with one of California’s other tolling agencies. For a list of toll facilities and agencies, visit:
