A toll pass that can work in multiple states can make interstate travel a lot easier, but at this time, it’s pretty unclear if your NTTA TollTag will work in Florida. You can definitely use the sticker TollTag in Kansas and Oklahoma, but the NTTA has not confirmed if this also works in Florida yet.
The North Texas Tollway Authority (NTTA) announced plans in 2017 to expand interoperability that would allow the TollTag to work in Florida, but there have been no updates as to whether those plans have been enacted.
Paying for tolls is a pain, but it’s sometimes a necessary evil to get where you need to go.
