Window Tint laws in Wisconsin
Under Wisconsin Statutes 347.41, no person shall operate a motor vehicle with any sign, poster, curtain, sticker, or other non-transparent material upon the front windshield, side wings, or side or rear windows. However, this section does not prohibit the use of tinted film on windows, provided that the film has a visible light transmittance (VLT) of not less than 35%. This applies to side windows to the immediate right and left of the driver and all windows to the rear of the driver. Factory-installed tinting that meets federal safety standards is generally allowed, but aftermarket tint must comply with the 35% VLT requirement. There are specific exemptions for certain vehicles, such as limousines, buses, and multipurpose passenger vehicles, which may have darker tint on windows behind the driver's seat. Additionally, vehicles used by persons with a medical condition requiring protection from sunlight may be granted an exemption, provided they carry a doctor's certificate. Law enforcement officers may use devices to measure VLT during traffic stops.
