^ in IL, you can have any percentage on the rear windows and none on the front two or winshield. On my grey car in the garage I had Limo all around and 50% on the winshield. I loved it because when the car was parked with the windows up and top on, you couldn't see inside of it be it night or day. BUT, I never really drove it with the windows up or the top on, so i never really got pulled over. with the targa off, and the winshield at 50%, not many people even noticed it was tinted. day or night, you can see out of it just fine.
