Minnesota Window Tint Laws: A Practical Guide
Window tint should improve comfort and appearance without creating an avoidable compliance problem. Minnesota rules vary by the type of vehicle and the window being tinted, so the correct starting point is the vehicle—not a shade sample alone.

Minnesota tint limits at a glance
Under Minn. Stat. 169.71, subd. 4, side and rear windows on a standard passenger vehicle must let at least 50% of light through (with a 3% tolerance), and film reflectance may not exceed 20% (also with a 3% tolerance). No reflective or tinting treatment is allowed on the windshield, and installed film must carry a permanent marking showing its light transmittance and reflectance.
Exemptions include the rear windows of pickups and vans, limousines, funeral vehicles, police vehicles, and vehicles covered by a qualifying medical prescription.
2025 update: SF 1075, effective July 1, 2025, changed the medical exemption. The prescription may now belong to the driver or a close relative who regularly rides in the vehicle, it must identify the vehicle, and it expires after two years unless the condition is listed as permanent.
Last reviewed September 2026. This summary is general information, not legal advice; the current statute text controls.
Start with visible light transmission
Visible light transmission, usually called VLT, describes how much visible light passes through the glass-and-film combination. A lower number means a darker result. Enforcement is based on the finished window, not simply the number printed on a film sample.
Factory privacy glass and aftermarket film are not interchangeable. The existing glass affects the final reading, which is why an installer should consider the actual vehicle before discussing a compliant result.
Vehicle type and window position matter
Minnesota Statutes section 169.71 addresses windshields and glazing. Passenger cars, multipurpose vehicles, trucks, vans, and limousines are not treated identically in every position. Windshield tint restrictions are especially strict, while some rear-window rules vary by vehicle classification.
Because statutes and interpretations can change, use the current Minnesota Revisor text as the controlling source. A blog post is useful preparation, but it is not legal advice or a substitute for current enforcement guidance.
Choose performance before darkness
Darkness is only one characteristic. Modern ceramic and multilayer films can provide substantial heat rejection and UV control at lighter shades. That gives drivers more room to balance visibility, appearance, comfort, and compliance.
- Ask about total solar energy rejection and infrared performance
- Consider nighttime visibility and winter driving
- Match front and rear glass thoughtfully
- Keep product and warranty documentation
Medical exemptions and documentation
Minnesota provides a medical-exemption process for qualifying needs. Drivers considering an exemption should review current state requirements and keep the required documentation available. An installer cannot determine medical eligibility.
