Hhhhmmm, not sure of some of this info...
I have a Sunpass and travel all over the state, even through EPass areas in Orlando, and have never had a problem.
I do recall having an old transponder a few years ago, that apparently quit working. We received a letter with a picture stating that they were deducting the toll from my account, which alerted me to get a new transponder...
No problems on any toll roads in FL with Sunpass, however I have never had an EPass, so maybe the people with the problems were using an EPass transponder, which I believe is a local Orlando thing. SunPass is state of FL...
I also believe that many or most states, now have the ability to share records, so you might want to look up your drivers license on your states data base and see if it shows...
In truth, a phone call will not prove much. IOW, you can call FL and ask, however it can come down to a particular agency...
I doubt FL would throw an out of state tourist in jail for a toll violation...
In the past, even different counties were not on the states' data base, that has changed...
How do I know?
I am the reason that all FL drivers licenses end with a "-0"...mine ends with a "-1", as far as I know, still the only one in the state. ;-)
