Window tinting in Wisconsin
Wisconsin front doors stay lighter than most southern states. Summer glare on the interstate is still a real reason to film the glass.
In Wisconsin, front side windows must let at least 50% of visible light through. Rear glass must let at least 35% of visible light through. Windshield film stays a clear strip at the top, not a full tint. House and storefront film is not held to that driving rule. This is a summary of published limits, not legal advice.
