Wisconsin's window tint laws can be confusing. This guide will clarify the legal limits, exceptions, and potential penalties for violating these regulations. Understanding these rules is crucial for drivers to avoid fines and ensure their vehicle's window tint complies with state law.

Wisconsin Window Tint Laws: The Basics

Wisconsin Statute 347.46 governs vehicle window tinting. The law focuses on the amount of visible light transmitted through your vehicle's windows. This is measured using a device called a light meter. The key percentage to remember is the visible light transmission (VLT).

Front Windshield:

No tint allowed on the front windshield. There is no exception to this rule, and even a very light tint is illegal.

Front Side Windows:

Minimum 35% VLT is required for front side windows (windows immediately behind the driver and front passenger). This means at least 35% of the light must pass through the tint. Anything darker is illegal.

Back Side Windows and Rear Windshield:

No restrictions. Wisconsin law does not place limits on the tint allowed for back side windows and the rear windshield. You can have any level of tint on these windows. However, you must have functional mirrors on both sides of the vehicle.

Exceptions to Wisconsin Tint Laws

While the above rules generally apply, some exceptions exist:

Medical exemptions: Individuals with certain medical conditions may be granted an exemption from the tint requirements. Documentation from a licensed physician is needed. Contact the Wisconsin Department of Transportation (DOT) for details on the application process.
Factory-installed tint: If your vehicle came with tinted windows from the factory, it’s likely to meet the legal requirements. However, it’s always advisable to check the VLT percentage to be sure.

Penalties for Illegal Window Tint in Wisconsin

Driving with illegal window tint in Wisconsin can lead to:

Citations and fines: Expect a citation and fine from law enforcement if your vehicle's tint doesn't meet the legal requirements. The amount of the fine can vary.
Vehicle repair orders: You may be required to have the illegal tint removed before you are allowed to drive your vehicle again.

Measuring Your Window Tint

While you can't accurately determine the VLT percentage yourself without a professional light meter, you can get a general idea. Stand inside your vehicle on a sunny day. Look at your vehicle's front side windows from outside. Can you clearly see what's inside? If not, your tint is likely too dark and needs to be lightened to meet the 35% VLT minimum.

Tips to Stay Compliant

Check your tint: Before driving, confirm that your vehicle's window tint complies with Wisconsin's regulations.
Consult a professional: If you are unsure about your tint’s legality, a professional window tinting shop can measure the VLT and advise you on any necessary adjustments.
Keep records of exemptions: If you have a medical exemption, always keep a copy of the documentation in your vehicle.
