I see cops all the time on the side of the road pulling people's tint off their windows. Out of State, in State... they don't care. While at the beach a couple of weeks ago, I saw them pealing tint off of a car with Michigan tags. Just the front windows.like having windows tinted too dark.
You probably won't be bothered on the interstate, because our State Troopers are the biggest losers on the planet, and I've only seen them on there, like maybe twice in the last year... but local cops... Barnie Fife will get you. And, I am not sure if they ticket you, but I do see all the time, they just peel that shit off right there on the side of the road.
