I might be the last to know this LOL...
But EZ Pass now works on Florida toll roads according to the EZ Pass web site.
Yeah for one less thing to deal with on the LDX Rally!
Toll highways are the exclusive purview of the states. They're privately operated corporations; no federal authority.
We're not far from a single standard. EZ Pass/Sun Pass Pro work on virtually every toll road on the eastern seaboard. If the Great State of Texas and The People's Democratic Republic of California would get on board, that'd be dang near all of it.
