Minnesota Window Tint Laws Explained: Legal VLT Limits for 2026

Minnesota tint laws are strict on the front but give SUV owners full freedom on the rear. The state also has specific rules about reflectivity that catch people switching from metallic films. Here is how the law breaks down so you can make an informed choice before your next install.

The Short Answer

In Minnesota, front side windows must let in at least 50% of visible light. Sedans must maintain 50% VLT on rear side windows as well. SUVs, vans, and trucks can run any darkness on rear side windows. The back window can be any darkness on all vehicle types. The windshield allows non-reflective tint above the AS-1 line only.

What VLT Means

VLT stands for visible light transmission — the percentage of light that passes through glass and film combined. Lower numbers mean darker film. Minnesota’s 50% front limit is moderate. At 50%, you get a subtle but visible tint that reduces glare and blocks UV without dramatically darkening the glass. In Minnesota’s long winters with low-angle sun and snow glare, even moderate tint makes a real difference in driving comfort.

Minnesota Tint Limits by Vehicle Type

Minnesota’s tint regulations are governed by Minnesota Statute §169.71. The sedan vs. multipurpose vehicle split affects the rear side windows.

Windshield Rules

Minnesota allows non-reflective tint above the AS-1 line on the windshield. Film below the AS-1 mark is not permitted. Minnesota State Patrol interprets this consistently — visible aftermarket film below the line will draw a citation.

Reflectivity Restrictions

Minnesota caps front side window reflectivity at 25%. Rear window reflectivity does not have a specific statutory limit, but highly reflective or mirror-finish films can still draw enforcement attention. Standard ceramic and carbon films fall well under the front reflectivity cap. Metallic films are the ones to watch — if you are upgrading from an older metallic tint, confirm the new film’s reflectivity spec is under 25%.

Medical Exemptions in Minnesota

Minnesota allows medical exemptions for drivers with conditions that require additional UV protection. A licensed physician must provide documentation specifying the medical condition and the recommended tint level. The exemption allows darker tint on front side windows below the 50% VLT minimum. Documentation must be kept in the vehicle and presented during any traffic stop.

Enforcement in Minnesota

Minnesota State Patrol and local police can test your tint with a VLT meter during any traffic stop. A tint violation is a petty misdemeanor with fines typically around $50–$100 plus surcharges. The Twin Cities metro area (Minneapolis-St. Paul) sees the most enforcement, along with the I-94 and I-35 corridors. Greater Minnesota tends to be less aggressive about tint-specific stops, but any officer can cite you during a routine stop.

Minnesota does not have a mandatory annual vehicle inspection, which means there is no recurring inspection check on tint. Enforcement is entirely through traffic stops.

Choosing the Right Shade for Minnesota

Minnesota’s extreme climate — scorching summers and bitter, snow-covered winters — makes tint a year-round investment. In summer, ceramic film at 50% blocks meaningful heat and nearly all UV. In winter, the same film reduces snow glare from low-angle sun, which is a real safety benefit on Minnesota highways. For front windows, ceramic at 50% VLT is the standard legal play. Behind the driver, SUV owners go 15% or 5% for privacy. Sedan owners can run 50% on the sides and any darkness on the back window.
