In the State of Georgia the legal tint limit is 32% on the drivers and passenger windows.The windows to the rear of the vehicle and the rear window can be as dark tinted as you like.The tint on the front windshield can not go below the ASI mark on the windowwhich is 6".

It's interesting how you can be legal in one state and illegal in another.

Looks like in Wisconsin you can't tint your driver's side as dark as the passenger side.

I'm probably illegal, 50% is pretty light.
