Actually, it really depends on where you live... In some states, window tinting is against the law. Think about it.... You are pulled over for something by the police and the cop has NO CLEAR VIEW of the driver or passenger when they stop you... Someone could be in the passenger seat with a gun and cause bodily harm or death without the cop even knowing someone was sitting in the back... Before I go to the expense of tinting my windows, I sure would check with your State DMV to find out how legal that tinting is.. Just give them a call- - - better to be safe then sorry.
