How does FasTrak work at the toll plazas of the Bay Area bridges?

As your vehicle enters the toll lane, the toll tag (1) that is mounted on your vehicle's windshield is read by the antennae (2). As your vehicle passes through, your FasTrak account is charged the proper amount. Feedback is provided to you on an electronic display (3). If your vehicle does not have a toll tag, the system classifies you as a violator and cameras take photos of your vehicle and your license plate for processing.
