On most USA toll roads, bridges, and tunnels you will have three payment options to pay your tolls.
There was no standard way to pay your tolls. Tag transponders are not interoperable. If you have transponder for one road, it may not work on another. Good news is that now you can use Tollguru™ Toll Calculator to know the payment methods allowed on each toll plaza along your route.
Please refer to toll information for your state to learn more about toll payment options such as state specific tag transponders and cash tolls.
