Window tint provides comfort, privacy, and protection from sunlight, but Minnesota law strictly regulates how dark vehicle window tint can be. If your windows appear darker than the legal limit, a police officer may stop your vehicle to check whether the tint complies with state law.

Understanding Minnesota Window Tint Limits
Minnesota regulates window tint to ensure that drivers maintain adequate visibility on the road. For most passenger vehicles, the law requires that windows allow at least 50% visible light transmission. These Minnesota window tint limits apply to front side windows, rear side windows, and the rear window for most vehicles. Highly reflective or mirrored tint is also prohibited. If your vehicle has tint darker than the legal limit, an officer may measure the tint using a light transmission meter. If the tint falls below the legal threshold, the officer may issue a citation unless you can provide proof of a medical exemption.
Why Documentation Is Required
Minnesota allows drivers with qualifying medical conditions to legally install darker window tint. However, the law requires that this exemption be supported by written documentation from a licensed physician. This document explains that darker tint is medically necessary for the driver or passenger and specifies the appropriate light transmittance level.
Without this documentation present in the vehicle, law enforcement officers have no way to verify that the darker tint is legally justified. Because of this, officers typically enforce the standard Minnesota window tint laws unless the driver can show proof of exemption.
What an Officer May Do During a Traffic Stop
If an officer suspects your window tint is darker than legally permitted, they may stop your vehicle to inspect the tint. During the stop, the officer may:
- Visually inspect the tint
- Use a tint meter to measure visible light transmission
- Ask if you have a medical tint exemption
- Request to see documentation
If you cannot produce valid Minnesota tint exemption documentation, the officer may issue a citation for illegal window tint. This can happen even if you actually qualify for a medical exemption but simply do not have the documentation with you at the time.

Possible Consequences of Not Having Documentation
If you are stopped without proof of your exemption, several outcomes are possible depending on the situation.
Common consequences include:
- A citation for illegal window tint
- A warning requiring you to remove the tint
- Instructions to provide proof of exemption later
In many cases, drivers may be able to resolve the situation later if they can show valid documentation. However, this process can still require time and court appearances. Keeping documentation in your vehicle helps avoid these complications.
How Medical Tint Exemptions Work in Minnesota
Minnesota law allows a medical window tint exemption in Minnesota when a licensed physician determines that reduced exposure to sunlight is medically necessary. The physician must provide written documentation confirming the medical need for darker tint. The document typically specifies the minimum light transmittance required and whether the condition is temporary or permanent. This document serves as legal proof that your tint is permitted under state law. However, the law requires that the documentation be carried inside the vehicle whenever the vehicle is driven.
