I want to get my car tinted and want to stay legal. The only issue is I drive to various states often and don't want to get in trouble. Here in IL I can tint the back windows as dark as I want but other states like FL have limits. So what is the safest tint % to stay legal in various states. I will only be tinting the back windows but was looking at 5%. Is it really a big deal with the back windows, Will an officer pull me over just for dark rear windows? I do carry when driving out of state and would prefer to avoid unnecessary police stops.
