Yes. FasTrak drivers must have a transponder mounted to their vehicle's windshield.  Transponders make it easier for tolling agencies to charge the correct toll to the appropriate vehicle automatically, resulting in faster processing times with higher levels of accuracy. State law requires a transponder to be in the vehicle or valid license plates properly mounted to the vehicle. See CA Vehicle Code section 23302.

Please note, if you have a vehicle with a metalized windshield listed on your account, you can request an external headlamp sticker transponder by logging into your account at TheTollRoads.com. Once logged in, select “Transponders” and “Request” a headlamp sticker. You can also make the request by calling our Customer Service Call Center at 949-727-4800.
