Yes, 15% window tint is legal in Wisconsin for rear windows and back side windows, provided it complies with state regulations. Front side windows and windshields must allow over 70% light transmission. Local jurisdictions may impose stricter rules, and non-compliance risks citations under Wisconsin Statutes § 347.43.
Key Regulations for 15% Window Tint in Wisconsin
- Front Side Windows: Must transmit more than 70% of light; 15% tint fails this requirement.
- Rear and Back Side Windows: Permitted if vehicle has side mirrors; 15% tint is acceptable.

Wisconsin enforces these rules through local law enforcement and the Wisconsin Department of Transportation (WisDOT). Municipalities like Milwaukee and Madison may impose additional restrictions, including reflective or metallic tints. Violations may result in fines up to $200 per offense. As of 2026, WisDOT is reviewing potential updates to light transmission standards, though no changes have been finalized. Drivers should verify local ordinances before installation to avoid penalties.
