Minnesota window tint laws require front side windows to allow at least 50% VLT on passenger cars, SUVs, vans, and pickups. The windshield may not carry any added tint. Rear windows on passenger cars follow the same 50% rule, while SUVs, vans, and pickups may go darker on rear windows. This guide covers penalties, exceptions, and the 2025 medical exemption update under Minnesota Statutes Section 169.71.
Key Terms Defined
VLT stands for visible light transmittance. It measures the percentage of light passing through the combined glass and film on a window. A higher VLT percent means more light gets through and the tint looks lighter, while a lower percent means less light passes and the tint looks darker. Reflectance is a separate measurement describing how mirror like a tinted window appears from outside, and Minnesota regulates both figures independently.
What the Law Says
Minnesota Statutes Section 169.71 sets the core rules for window glazing and tint on vehicles registered in the state. The statute prohibits any added tint on the windshield itself. Front side windows must allow at least 50% VLT, with a 3% measurement tolerance applied by enforcement. Reflectance on tinted windows may not exceed 20%, also carrying a 3% tolerance built into the enforcement standard.
Who It Applies To
The tint rules apply to any motor vehicle required to be registered in Minnesota, covering passenger cars, SUVs, vans, and pickup trucks operated on public streets. Limousines and vehicles used to transport human remains by a licensed funeral establishment fall under separate exceptions in the statute. Factory installed glazing meeting Federal Motor Vehicle Safety Standard 205 is treated differently from aftermarket tint film applied after a vehicle leaves the factory.
Requirements for Passenger Cars
Standard passenger cars including sedans, coupes, convertibles, station wagons, and hatchbacks face the strictest version of Minnesota tint rules. The windshield allows no added tint at all. Front side windows, rear side windows, and the rear windshield must all allow at least 50% VLT under the statute. Reflectance on any tinted window may not exceed 20%. These limits apply uniformly across every window position on a passenger car.
Requirements for SUVs Vans and Pickups
Multi purpose vehicles including SUVs, vans, and pickup trucks follow a different standard on rear windows. Front side windows on these vehicles must still meet the same 50% VLT minimum required for passenger cars. The rear side windows and rear windshield on SUVs, vans, and pickups may be tinted to any darkness level. This distinction is one of the most confused points in Minnesota tint law.
Penalties or Consequences
Driving with tint that fails the VLT or reflectance limits is generally treated as a civil equipment violation for the vehicle operator. Citation amounts vary by county and by whether the violation is a first or repeat offense, so a single fixed dollar figure does not apply statewide. A driver cited for illegal tint may also receive a fix it order requiring correction and proof of compliance.
Exceptions and Limitations
Section 169.71 allows several defined exceptions to the standard VLT and reflectance limits. Factory installed glazing that has not been modified since original installation and meets Federal Motor Vehicle Safety Standard 205 is exempt from the aftermarket tint rules entirely. Rear windows on pickup trucks, and rear windows on vans, may carry darker film under the vehicle class rules. Limousines and funeral transport vehicles also qualify for exceptions.
Medical Exemption Rules
A driver or passenger with a documented medical need may qualify for a tint exemption that exceeds the standard 50% VLT limit. The prescription or physician statement must specify the minimum light transmittance allowed and state whether the medical condition is temporary or permanent. Effective July 1, 2025, Minnesota expanded who a prescription may cover under HF 1243, 94th Minnesota Legislature, amending subdivision 4a.
The 2025 Medical Exemption Expansion
Before July 1, 2025, a medical tint exemption generally covered only the vehicle operator named in the prescription itself. The amended law now allows a driver to rely on a prescription issued to a parent, child, grandparent, grandchild, sibling, or spouse. It also covers a person for whom the driver serves as a personal care attendant, expanding who can benefit from a single qualifying medical prescription under state law.
Documentation Requirements
A valid medical exemption prescription issued on or after July 1, 2025 must meet specific documentation standards under the amended statute. It must state whether the underlying medical condition is temporary or permanent and indicate the minimum light transmittance percentage allowed for that individual. The document needs an expiration date no more than two years after issuance unless marked permanent, and the driver must keep it in the vehicle.
Common Misconceptions
Many drivers assume Minnesota applies one single tint rule to every vehicle type, when the statute separates passenger cars from SUVs, vans, and pickups on rear window darkness. Another frequent misunderstanding treats any tint violation as a criminal matter, when driving with noncompliant tint is generally a civil equipment violation. Some drivers also believe reflectance and VLT describe the same measurement, though Minnesota regulates them as two separate standards.
Verifying Current Rules
Minnesota tint law was substantively amended in 2025, and enforcement practices can shift at the county level even when the statute stays the same. The Minnesota Driver’s Manual, Department of Public Safety restates the core VLT and reflectance rule in plain language. Laws and enforcement may change, so drivers should check official state sources for the latest rules. For general background, see the Disclaimer page.
