To back up what Valkryderguy said in Illinois front Drivers side and passenger side windows cannot be tinted, and the Ticket is 75 dollars. My next door neighbor has been redoing a 1978 Camaro and had the windows tinted, it looked great, first time he drove it came home with a ticket with instructions to remove the tint on the front and two front windows, now the car looks weird, he will probably remove all the tint and let it go. Another friend at work has had his tinted for years and never been stopped, who really knows, just depends on the officer and how they want to inforce the law.
