Minnesota drivers must normally follow strict Minnesota window tint laws that regulate how dark vehicle window tint can be. For most vehicles, windows must allow at least 50% visible light transmission. However, the state recognizes that certain medical conditions can make exposure to sunlight painful or harmful.

Why Some Medical Conditions Require Darker Window Tint
Sunlight contains ultraviolet (UV) radiation and intense visible light that can trigger symptoms for certain medical conditions. For individuals who experience sensitivity to light, exposure to sunlight while driving can cause severe discomfort or worsen existing health issues.
Darker window tint can help reduce sunlight exposure, decrease glare, and filter harmful UV radiation. This added protection can make driving safer and more comfortable for individuals with light-sensitive medical conditions. When a physician determines that darker tint is medically necessary, Minnesota law allows drivers to exceed the normal Minnesota window tint limits.
Common Medical Conditions That May Qualify
While each case must be evaluated individually by a physician, several medical conditions commonly qualify for tint exemptions due to increased sensitivity to sunlight.
Lupus
Lupus is one of the most commonly cited conditions for window tint exemptions. Individuals with lupus often experience severe sensitivity to ultraviolet light, which can trigger skin reactions, fatigue, and flare-ups of the disease. Darker window tint can help reduce UV exposure and minimize symptoms during daily travel.
Photosensitivity
Photosensitivity is a condition where exposure to sunlight causes discomfort, skin irritation, or other health issues. This sensitivity may occur on its own or as a symptom of another medical condition. Drivers with photosensitivity may benefit from darker tint that helps block sunlight and glare.
Albinism
Albinism is a genetic condition that reduces or eliminates pigmentation in the skin, hair, and eyes. Individuals with albinism often experience significant sensitivity to sunlight and bright light. Because their eyes are particularly sensitive to glare, darker window tint can provide valuable protection while driving.
Skin Conditions Affected by Sunlight
Certain dermatological conditions become worse when exposed to sunlight. These conditions may include severe rosacea, eczema, or other disorders where UV exposure aggravates symptoms. In these cases, physicians may recommend darker window tint to reduce direct sunlight exposure during travel.
Melanoma and Skin Cancer
Individuals who have been diagnosed with melanoma or other forms of skin cancer are often advised to limit exposure to ultraviolet radiation. Because sunlight can worsen these conditions or increase future risk, darker window tint can provide an additional layer of protection. For patients with a history of skin cancer, reducing UV exposure while driving may be medically recommended.
Solar Urticaria
Solar urticaria is a rare condition in which exposure to sunlight causes painful skin reactions such as hives or swelling. Even short periods of sun exposure can trigger symptoms. Darker window tint may help reduce the intensity of sunlight exposure while driving.
Eye Conditions Causing Light Sensitivity
Certain eye disorders can cause extreme sensitivity to bright light or glare. Conditions such as retinal disorders, post-surgical eye sensitivity, and other ophthalmological issues may require reduced exposure to sunlight. In these situations, darker window tint can help protect the eyes from excessive brightness.

Every Case Is Evaluated Individually
While the conditions listed above are commonly associated with tint exemptions, Minnesota law does not limit exemptions to a specific list of diagnoses. Instead, the key factor is whether a licensed physician determines that darker window tint is medically necessary for a particular patient. Each case must be evaluated individually, and the physician must confirm that reduced sunlight exposure is required for the patient’s health.
Documentation Required for a Minnesota Tint Exemption
To legally install darker window tint, drivers must obtain proper Minnesota tint exemption documentation from a licensed physician.
This documentation typically includes:
- The physician’s name and signature
- A statement confirming medical necessity
- The required level of light transmittance
- Patient identification information
- An indication of whether the condition is temporary or permanent
This document must be kept in the vehicle at all times when operating a vehicle with darker-than-legal window tint. If a law enforcement officer questions the tint during a traffic stop, presenting the documentation confirms that the tint is legally permitted.
How Drivers Obtain a Minnesota Tint Exemption
The process for obtaining an exemption begins with a consultation with a licensed physician. The physician reviews the driver’s medical condition and determines whether darker tint is medically necessary. If the physician approves the exemption, they issue documentation supporting a medical window tint exemption in Minnesota. Drivers must then keep the documentation inside the vehicle whenever driving with darker window tint.
