A window tint exemption in Massachusetts allows qualifying individuals to request permission for darker or specialized window tint when it is medically necessary due to light sensitivity or photosensitivity. Massachusetts law generally limits most vehicle window tint to 35% visible light transmission, but the state does recognize medical exemptions for individuals whose conditions require additional protection from sunlight or UV exposure. Without an approved waiver, darker-than-legal tint can result in citations, fines, or repeated violations that may even lead to license suspension.
The exemption qualification process involves two parts:
Some people ask whether a Massachusetts tinted glass waiver allows them to tint their windows as dark as they want. The answer is no—Massachusetts does not provide unlimited tint privileges simply because a medical condition exists. Instead, the state reviews each application individually through the RMV Medical Advisory Board to determine whether special window treatment is medically necessary for a light-sensitive or photosensitive driver. Any darker tint used should be consistent with the approved medical accommodation and supported by proper exemption documentation.
It’s important for Massachusetts drivers to understand the state’s vehicle window tint laws, even if you are considering applying for a medical window tint exemption. Massachusetts has strict regulations governing how dark and reflective vehicle window tint may be. These laws are intended to maintain visibility and roadway safety while still allowing drivers reasonable protection from sunlight and heat.
Massachusetts does allow medical exemptions for individuals who are light-sensitive or photosensitive and require additional protection from sunlight. However, unlike some states, Massachusetts requires applications to be reviewed through the RMV Medical Advisory Board process. A physician licensed in Massachusetts must provide written attestation supporting the medical necessity for special window treatment before a waiver may be approved.
Traditionally, getting a tint exemption in Massachusetts meant making an in-person doctor’s appointment, explaining your condition, and handling paperwork yourself. ForeverTint streamlines this entire process 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.
To support a Massachusetts tinted glass waiver application, the physician documentation should include:
Massachusetts law requires the application to be submitted to the Medical Advisory Board for review. If the Board grants the waiver, the Registrar issues the waiver; the statute provides for a sticker affixed to the side window next to the driver, and since January 2025 the RMV also issues a registration marked “Vehicle with Tinted Glass Waiver.” The waiver does not guarantee you will not be stopped or cited; officers retain discretion.
M.G.L. c. 90, § 9D(8) exempts “special window treatment or application determined necessary by a licensed physician, for the protection of the owner or operator of a private passenger motor vehicle who is determined to be light or photosensitive. Applications for such exemption based upon such medical reason or reasons shall be made in writing to the medical advisory board established under section eight C. All applications must be supported by a written attestation of a physician licensed to practice in this commonwealth of the necessity thereof.”
The RMV considers only permanent conditions and requires the physician to certify that polarized sunglasses are not sufficient.
Massachusetts law allows medical window tint exemptions for individuals who are light-sensitive or photosensitive and require additional protection from sunlight. To legally qualify, the request must be supported by a written attestation from a licensed Massachusetts physician and reviewed through the RMV Medical Advisory Board process. Without approved documentation, darker-than-legal tint can still lead to citations and fines.
ForeverTint helps connect Massachusetts residents with licensed physicians who can evaluate whether a medical condition may qualify for a tinted glass waiver. If you qualify, you receive the medical documentation needed to support your application through the Massachusetts RMV Medical Advisory Board process. Final approval of the waiver is ultimately determined by the Commonwealth of Massachusetts.
If your vehicle’s tint appears darker than Massachusetts law normally allows and you cannot provide proof of an approved exemption, you may still receive a citation. Massachusetts takes window tint violations seriously, and repeated offenses can result in increased penalties or even license suspension. Keeping your exemption approval and official documentation properly maintained is extremely important.

No, a Massachusetts medical tint exemption does not automatically allow unlimited darkness on all vehicle windows. The RMV Medical Advisory Board reviews each application individually to determine what accommodation is medically appropriate. Any tint used should remain consistent with the approved waiver and medical necessity documentation.
Yes. Massachusetts requires medical tint waiver applications to be submitted to the RMV Medical Advisory Board for official review. A physician’s written attestation alone is not the final approval; the Commonwealth must review and approve the request before issuing an official exemption sticker.
The process starts by obtaining medical documentation from a physician licensed in Massachusetts who can confirm that special window treatment is medically necessary due to light sensitivity or photosensitivity. ForeverTint helps simplify this process by arranging physician consultations and helping you obtain the supporting documentation needed for your RMV waiver application.
Massachusetts waivers are for people who are light or photosensitive, such as those with lupus, albinism, porphyria, or solar urticaria. The RMV considers only permanent conditions, and the Medical Advisory Board decides each application.
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.
