Where can I find out if there is a state law on window tint? Me and a guy from work are arguing about if there is a state law on tint. I have talked to two OKC cops and they told me there is not a state law anymore. But if I google okla tint laws they show that there is a law enacted in 2005. I'm just trying to find out if there still is a state law limiting how dark you can tint your car. I know that cities can have their own limits.
