I have a '95 2 door civic with 5% on the driver side and passenger, 5% on the back, and a 5% brow on my windshield. It use to be illegal in my state (missouri) but the law got all screwed in legislation, so all cops can do now is try to give you a ticket and harass you but as long as you go off about how you checked with your local law enforcement and it's legal they can't do anything. It is illegal however to have the middle of your windshield tinted. I love the darkness cuz no one can see me but i can't back up..period, and at a four way stop i can't see left or right at night, so i just pray peeps have their lights on....it's pretty dangerous but i can't say i would want it changed...
