SunpassSun Pass Transponder Portable Prepaid Toll Program for Florida Only

We grabbed this SunPass Pro for our upcoming Great American Road Trip™ through West Virginia, Kentucky, Tennessee, Virginia, and Washington DC. We already owned the smaller, non-pro version—which was great, if you never plan to leave Florida. Basically, it’s the Disney World of toll passes: magical, but doesn't work outside the state.This upgraded "Pro" version supposedly covers the states we need. The packaging proudly claims compatibility with those states... except Tennessee. Why? No idea. Maybe Tennessee just really likes doing things its own way. As for Washington DC—well, that’s still a mystery. It might work, or it might trigger a congressional hearing. We'll report back.To get started, you’ll need to register the pass with a U.S. address. We used the address of a villa we stayed in years ago, which felt slightly dodgy but also kind of genius. The app isn't available in the UK, so we went full tech-nerd and downloaded the APK like hackers on a mission... to avoid toll fines.All in all, thrilled we found it on Amazon UK. Now we can glide through toll booths like locals—with just a tiny chance of being chased down in Tennessee.
