Yes, 15% window tint is legal in Michigan, but only for the rear windows of passenger vehicles.
Michigan’s 2026 compliance framework, enforced by the Secretary of State and Michigan State Police, permits 15% VLT (Visible Light Transmission) on rear side and back windows, provided front-side windows meet 70% VLT. Local jurisdictions like Detroit and Grand Rapids conduct periodic roadside inspections, with violations incurring $100 fines and mandatory tint removal. The 2025 amendments to MCL 257.709(1)(a) clarified rear-window exemptions for sedans, SUVs, and trucks, aligning with federal NHTSA safety standards.
Key Regulations for 15% Window Tint in Michigan
- Front Side Windows: Must maintain ≥70% VLT; 15% tint is prohibited.
- Rear Side & Back Windows: Permitted ≥15% VLT for all vehicles except school buses and emergency vehicles.
- Windshield: Non-reflective tint above the AS-1 line is banned; medical exemptions require MDOT approval.
Vehicles registered out-of-state must comply with Michigan’s standards within 30 days of residency. Dealers face liability for installing non-compliant tint, per the 2024 Michigan Auto Dealers Association guidelines. Law enforcement may issue citations based on reflectivity measurements, not just VLT estimates.
