with window tinting as long as youre not a douche bag you can usually get away with whatever you want so long as you follow certain "guidelines"
Ive got 5% tint and have never had a problem if you follow these 2 simple steps.
#1 when you get pulled over immediately roll down your driver and passenger windows. Cops hate dark tint because they cant see inside the car. If you roll down the windows then when they shine their blinder spot light on your driver/passenger mirror it will light up the inside of the car allowing them to see in and there wont be an issue.
#2 Dont be an asshole. If you start shooting your mouth off like your crap doesnt stink and that the cop is doing you some injustice by pulling you over then guess what... The cop is just going to be looking for crap to site you on. Thats usually when you hear of people getting ride height violations, noise violations, tint violations, obstruction of view violations and whatnot.
