Confused on I Pass and Sun Pass etc--- toll roads ????

Also remember, if you are operating a Class C, frequently the iPass transponder will not transmit if you have it stuck in the windshield due to the design of the cabover interfering with transmission. They also make a version that attaches to your front license plate which is far more practical for the Class C's.

After a certain number of missed tolls, they will begin charging you a hefty fine each time they have to manually look up your information from the database.
