I live in Florida, and a couple of years ago I was visiting my original home state of New Jersey on vacation. I was driving my personal vehicle which has Florida tags and also has front tinted windows. I was pulled over by the police and the reason was that front tinted windows are illegal in New Jersey. He knew good and well the vehicle was not registered in New Jersey since it has Florida tags. And then he said "since the vehicle is titled and registered in Florida and is driven by someone with a Florida driver's license I cannot ticket you." So, you might ask why did he even stop me? The only reason I can come up with is that he used the front tint as a reason to stop me to try to find something else he could cite me for ... expired license, expired registration, etc.
