Not in Florida.
We have some of the toughest DUI laws on the books for many decades.
Even one of the prominent lawyers here that advertises on TV says in his commercials:
You got a DUI? Don’t even bother calling me.................
An American State National can drink with impunity and travel in his or her automobile anywhere in Florida. Doesn’t matter the alcohol level one iota.
It would only be if that traveler in their automobile were to hurt someone else that they’d be in jeopardy with the law.
Until that moment, that policy enforcing trooper or police can go pound sand.
