A Wyoming medical tint exemption is a certificate issued by the director of the Wyoming Department of Transportation, not by a doctor. Without a certificate, side and rear windows must let in 28% or more of light, and darker tint can result in a citation. With a certificate, tint on the windshield and any or all windows may reduce light transmission to no less than 25%, with a stricter limit for the lower windshield.
The process involves two parts:
Some drivers ask whether a Wyoming medical tint certificate lets them tint their windows as dark as they want. It does not. With a certificate, tint on the windshield and any or all windows may not reduce light transmission below 25%. On the windshield, total light transmittance must stay at 70% or more, except for the upper five inches or the AS-1 line, whichever is closer to the top.
ForeverTint connects you with an independent licensed physician who reviews your medical history by chart review or, occasionally, a brief phone call. If you qualify, the signed physician statement is emailed to you so you can submit it to the Wyoming Department of Transportation and request your certificate.
It’s important for Wyoming drivers to understand the state’s window tint laws, even if you are considering a Wyoming medical window tint exemption. Wyoming has specific regulations that control how dark or reflective your vehicle’s window tint can be. These laws are intended to maintain driver visibility and roadway safety while still allowing reasonable sun protection and privacy.
These limits mean that tint darker than 28% on regulated windows requires a medical certificate from the Wyoming Department of Transportation. ForeverTint helps you find out whether you qualify for the physician statement that WYDOT requires before it issues a certificate. Eligibility is determined by a licensed physician based on your medical history, and WYDOT decides whether to issue the certificate.
Traditionally, getting a physician statement for a Wyoming tint certificate meant making an in-person doctor’s appointment. ForeverTint moves the physician review online:
*If the physician determines you do not qualify, you receive a full refund.
An independent licensed physician decides whether your condition qualifies. Conditions a physician may consider include:
Lupus is an autoimmune disease in which ultraviolet light can trigger skin rashes, joint pain, and fatigue. Physicians commonly advise people with lupus to limit UV exposure, including the UVA light that passes through car side windows.
Porphyrias are a group of disorders in which certain compounds build up in the body and react to light, causing blistering, burning pain, and skin damage after sun exposure. Avoiding sunlight is a central part of managing the cutaneous forms.
Xeroderma pigmentosum is a rare genetic disorder that prevents the body from repairing DNA damage caused by ultraviolet light. People with XP burn after minimal sun exposure and face a greatly increased risk of skin cancers and eye damage.
People with albinism produce little or no melanin, the pigment that helps protect skin and eyes from ultraviolet light. They are highly prone to sunburn and skin damage and often experience significant light sensitivity and glare.
Photosensitivity dermatitis is an abnormal skin reaction to sunlight that can cause redness, itching, swelling, and rash on exposed skin. It can be linked to an underlying condition or to medications, and limiting UV exposure helps prevent flare-ups.
A personal history of melanoma or other skin cancers means ongoing UV exposure is a serious concern. Dermatologists routinely advise these patients to reduce sun exposure wherever possible, including time spent driving.
Some eye conditions, such as uveitis, certain retinal disorders, and sensitivity following eye surgery, cause pain or impaired vision in bright light. A licensed physician or optometrist can assess whether reducing light exposure while driving is medically necessary.
Cockayne syndrome is a rare genetic disorder that causes extreme sensitivity to sunlight, along with other developmental and health effects. Strict sun protection is part of everyday care.
Bloom syndrome is a rare inherited disorder that causes sun-sensitive skin, often with a facial rash after sun exposure, and an increased lifetime risk of cancer. Limiting UV exposure is a standard precaution.
Vitiligo causes patches of skin to lose their pigment, leaving those areas without natural protection from ultraviolet light. Depigmented skin burns easily, so physicians often recommend extra sun protection.
Some autoimmune conditions, such as dermatomyositis, cause skin and muscle symptoms that worsen with sun exposure. Certain medications used to treat autoimmune disease can also increase sensitivity to light.
Healing burns, skin grafts, and scar tissue are more vulnerable to sun damage, and UV exposure can cause scars to darken. Physicians typically advise protecting these areas from direct sunlight.
Other diagnosed conditions, including sun sensitivity caused by medications, can make sun exposure a health concern. Describe your condition during intake, and an independent licensed physician will review your medical history and decide whether darker tint is medically necessary for you.
Under W.S. 31-5-962(m), the statement must:
The certificate is valid as long as the condition requiring the tint persists or until the vehicle is sold, whichever comes first. At the director’s discretion, one or more certificates may be issued to an individual or a family. The driver or an occupant must have the certificate in their possession while the vehicle is operated on a highway.
A physician statement by itself is not a Wyoming tint certificate. Without a certificate from the Wyoming Department of Transportation in the vehicle, tint darker than 28% on regulated windows can result in a citation, even if your medical condition is legitimate. A certificate does not guarantee you will not be stopped or cited; officers retain discretion.
Wyoming Statutes Section 31-5-962(d): “A sunscreening device, when used in conjunction with the safety glazing materials of the side wings or side windows, or both, located at the […] right and left of the driver, shall be a nonreflective type and have total light transmission through both the sunscreening device and glazing of not less than twenty-eight percent (28%).”
Wyoming Statutes Section 31-5-962(m): “Notwithstanding the requirements of this section, a motor vehicle operated by or regularly used to transport any person with a medical condition which renders him susceptible to harm or injury from exposure to sunlight or bright artificial light may be equipped, on its windshield and any or all of its windows, with sun shading or tinting films or applications which reduce the transmission of light into the vehicle to levels not less than twenty-five percent (25%). The sun shading or tinting film when applied to the windshield of a motor vehicle shall not cause the total light transmittance to be reduced to any level less than seventy percent (70%), except for the upper five (5) inches of the windshield or the AS-1 line, whichever is closer to the top of the windshield. Vehicles equipped with sun shading or tinting films as provided in this subsection shall not be operated on any highway unless the driver or an occupant of the vehicle has in his possession a certificate issued by the director authorizing such operation. The director shall issue the certificate only upon receipt of a signed statement from a licensed physician or licensed optometrist identifying the person seeking the certificate and stating that, in the physician’s or optometrist’s professional opinion, the equipping of a vehicle with sun shading or tinting films or applications is necessary to safeguard the health of the person seeking the certificate. Certificates issued by the director under this subsection shall be valid so long as the condition requiring the use of sun shading or tinting films or applications persists or until the vehicle is sold, whichever first occurs. In the discretion of the director, one (1) or more certificates may be issued to an individual or a family.”
Wyoming law (W.S. 31-5-962) requires side and rear windows to let in 28% or more of light, with exceptions for windows behind the driver of trucks, SUVs, vans and similar vehicles. A vehicle used by or to transport a person whose medical condition makes them susceptible to harm from sunlight or bright artificial light may have tint down to 25% if the driver or an occupant carries a certificate from the WYDOT director. Without that certificate, darker tint can lead to a citation.
ForeverTint connects you with an independent licensed physician who reviews your medical history by chart review or, occasionally, a brief phone call. If you qualify, the signed physician statement is emailed to you. You then submit it to the Wyoming Department of Transportation yourself, and WYDOT decides whether to issue the certificate.
Wyoming law says a vehicle with medical-level tint may not be operated on a highway unless the driver or an occupant has the WYDOT certificate in their possession. If you are stopped without it, you can be cited for the tint. Even with a certificate, officers retain discretion.
No. With a certificate, tint on the windshield and any or all windows may not reduce light transmission below 25%. On the windshield, total light transmittance must stay at 70% or more, except for the upper five inches or the AS-1 line, whichever is closer to the top.
Yes. A doctor’s note alone does not authorize darker tint in Wyoming. The director of the Wyoming Department of Transportation issues the certificate after receiving a signed statement from a licensed physician or licensed optometrist, and the certificate must be with the driver or an occupant while the vehicle is driven.
First, a licensed physician or licensed optometrist reviews your medical history and, if darker tint is necessary to safeguard your health, signs a statement identifying you and stating that opinion. Then you submit the statement to the Wyoming Department of Transportation to request the certificate. The certificate is valid while the condition persists or until the vehicle is sold, whichever comes first.
Wyoming law does not list specific conditions; it covers a person with a medical condition that makes them susceptible to harm or injury from exposure to sunlight or bright artificial light. Conditions a physician may consider include lupus, porphyria, xeroderma pigmentosum, albinism, photosensitivity dermatitis, melanoma and other skin cancers, and light-sensitive eye conditions. An independent licensed physician decides whether your condition qualifies.
Having a medical recommendation from a doctor for darker window tint does not guarantee you will not get a ticket. An officer can still give you a ticket at their own discretion.
