Not a fan of this law because it is a pain in the butt looking through cars with tinted windows when backing up. I don't know how many times I've almost backed into somebody or walked infront of a car that was pulling out of a parking spot because I couldn't see through the windows of a car that I'm passing.
Plus, for the safety of our law enforcement officers, it is safer for them to be able to see exactly what is going on in a car while they're walking up.
Although it may be allowed by law, there is nobody forcing you to have tint. I do agree with you about super dark tint and law enforcement. Having had some experience with this, I can tell you you really have to be on your toes when that driver's window rolls down. You don't know if you are about to talk to a little old lady or a gang banger with a sawed off shotgun on his lap!
Wait, so if it's legal in IL but illegal in Chicago, is this based upon where you live or just the fact that you're in the city? When drivers from other states come into IL they could always have whatever tint was legal in their state. So if I have dark tint and live in the burbs, I can't drive downtown anymore?
Is there any practical benefit to tinting your front windows? I know people with vision issues that warrant the need can get a prescription which gives them an exemption, but is there any real purpose for anyone else? Sunglasses have always worked fine for me.
