The FasTrak Transponder
The Toll Roads offer a variety of transponders to best fit the needs of our drivers. Whether you have a sticker or switchable, all transponders issued by The Toll Roads can be used to pay tolls on any tolled bridge, lanes and road throughout California.
Because your FasTrak® transponder can be used on any tolled facility, you only need one account. When you open an account, it is important to do so with the agency that operates the facility that you’ll use most, to take advantage of programs and discounts that best match your driving habits.
FasTrak Sticker Transponder
FasTrak sticker transponders are the latest in electronic toll collection technology.
In 2019, The Toll Roads began offering new small, durable sticker transponders to replace existing hardcase transponders. Sticker and hardcase transponders are valid to pay tolls on all of California’s tolled bridges, lanes and roads.
FasTrak Switchable Transponder
Also known as FasTrak Flex®, FasTrak switchable transponders/FasTrak Flex transponders have a small black switch that can be moved to indicate the number of occupants in the vehicle.
Prior to starting each trip, 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+). Some tolling facilities allow qualifying carpools and eligible vehicles to drive for free or at a discounted rate. The Toll Roads do not offer carpool discounts, but FasTrak accountholders may be eligible for a frequent driver discount.
Please note that switchable transponders issued after July 5, 2020, are made with the same battery-free technology as sticker transponders and no longer beep when going through a toll point.
FasTrak Standard Transponder
Standard FasTrak transponders do not have a small black switch that can be moved to indicate the number of occupants in the vehicle. For toll facilities that require no transponder for qualifying carpools and eligible vehicles, removing the transponder from the vehicle or using an agency-provided Mylar® bag is suggested to avoid tolls being charged.
FasTrak External Transponders
FasTrak external transponders – used primarily on fleet and commercial vehicles – are attached to the vehicle's front license plate or are screw-mounted in the area on the front bumper where the license plate is normally located.
