Window Tint Laws in Minnesota: What You Need to Know
Window tinting can enhance your vehicle’s comfort and style, but if it’s too dark, you can end up with a ticket—and a requirement to remove the tint. Minnesota has specific laws governing how dark your window tint can be. This guide breaks down the rules so you can stay compliant and enjoy your tint.
Understanding VLT (Visible Light Transmission)
The key factor in tint law is Visible Light Transmission (VLT)—the percentage of light that passes through your window and tint film. A higher VLT means a lighter tint; a lower VLT means a darker tint.
Minnesota Tint Law Basics
Front Windshield
No aftermarket tint is allowed on the front windshield.
Front Side Windows
All vehicles (cars, SUVs, trucks) must allow at least 50% VLT, meaning tint must be light enough to let at least half of the light through.
Rear Side and Rear Windows
Passenger cars: Rear side windows and rear window must also meet the 50% VLT minimum.
SUVs, vans, and trucks: No minimum light-transmission requirement for rear side or rear windows. You can have much darker tint on these windows.
Reflectivity
Tint on any window cannot be reflective or mirror-like; Minnesota restricts reflectivity to prevent glare that could distract other drivers.
Medical Exemptions
Minnesota allows a medical exemption to go darker than the standard limits, but it must be backed by a written statement from a licensed physician. This document must:
Specify the required minimum VLT level,
Include an expiration date no more than two years from issuance,
Be carried in the vehicle to show law enforcement if asked.
Penalties for Non-Compliance
If your window tint doesn’t meet Minnesota’s legal standards:
You can be cited for illegal tint,
Often you’ll receive a “fix-it” ticket, meaning you may need to remove or adjust the tint to meet the law,
Fines can vary depending on the jurisdiction and severity of the violation.
Tips Before You Tint
1. Check your vehicle type.
The rules for passenger cars differ from SUVs and trucks, especially for rear windows.
2. Ask for the tint film specs.
Make sure the film comes with a VLT rating and reflectivity info permanently marked on it—that’s required by state law.
3. Keep records and stickers.
Keep your doctor’s statement if you qualify for a medical exemption. Enforcement relies on documentation if your tint looks darker than standard limits.
Why It Matters
Minnesota’s tint laws are designed to balance:
Driver visibility and safety,
Law enforcement needs to see inside vehicles,
Comfort and UV protection benefits of tinting.
