Why doesn't my transponder beep?

New tolling technology means beeping transponders are a thing of the past. Sticker transponders and FasTrak Flex^® switchable transponders issued after July 5, 2020, are made with battery-free technology and do not beep. If, for some reason, a toll isn’t collected based on a reading of a transponder, it is collected using a photograph of the vehicle’s license plates. So, make sure the vehicle information listed on your account is up to date.

If your switchable transponder was issued prior to July 5, 2020, and doesn’t beep, it may not be working properly. Please review your recent toll road activity. If you notice a high number of "pay-by-plate" transactions, you need a new transponder. To order a new transponder, log in to your account online or via The Toll Roads app, select "Transponders" and select "Request Transponder." 

Sticker transponders are available to accountholders at no cost. Switchable transponders are available for purchase. All transponders issued by The Toll Roads can be used on every tolled bridge, lane and road throughout California.
