To date, five separate tolling agencies in California have distributed more than 2.5 million FasTrak transponders. It's important to get a transponder from the agency that operates the road, lane or bridge you will use most. Each tolling agency has its own rules and minimum requirements.

FasTrak® is, by far, the easiest and preferred way to pay tolls on every tolled bridge, lane and road in California -- and, in some cases, it’s the only way to pay.
It's important to get a transponder from the agency that operates the bridge, lane or road that you’ll use most, because each tolling agency has its own rules and minimum requirements. On some of California’s express lanes, qualifying carpools and other select vehicles are eligible for free or discounted toll rates.
To be eligible for free or discounted toll rates, drivers need a switchable FasTrak transponders (also called FasTrak Flex ®) that has 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+).

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 or sticker FasTrak transponders can use the express lanes and pay with FasTrak, but they will pay the full toll regardless of the number of occupants in the vehicle.
