How does E-ZPass® work?

Graphic shows a vehicle passing through a tollboth.  A toll transponder on the windshield is read by an overhead antenna.  Account status is shown to the driver on the driver feedback display.

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