Sticker transponders do not beep. If your hardcase transponder 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 click "Replace” next to the transponder you wish to replace.
