They almost never pull you over for window tint. I was pulled over once for window tint, a small town where they didn’t recognize my car. Supposedly the business owner I knew complained about it and supposedly it won’t happen again.

It’s basically probable cause but most cops claim they don’t pull people over for it at all and were surprised when I claimed I had been. Just don’t try being a dick if you do get pulled over because there’s always that to get cited on
