An Indiana window tint exemption allows you to legally apply window tint that would otherwise violate the state’s limitations—particularly the 30% visible light transmission requirement on most windows. This exemption is especially important for drivers with medical conditions that require protection from direct sunlight or UV exposure. Without it, having darker tint could result in citations and fines. With proper documentation, however, it becomes a legally recognized medical accommodation under Indiana law.
The exemption qualification process involves two parts:
Some people ask whether an Indiana exemption lets them tint their windows as dark as they want. Indiana’s statute does not set a darkness limit for exempt vehicles, but the exemption depends on a current physician or optometrist certification that is carried in the vehicle and renewed every year. ForeverTint connects you with an independent licensed physician, and if you qualify, your certification is delivered electronically so it is ready to print and keep in your vehicle.
It’s important for all Indiana drivers to understand the state’s window tint laws—even if you don’t currently qualify for a medical window tint exemption. Indiana has clear guidelines that regulate how dark your vehicle windows can be tinted. These laws are designed to maintain visibility and safety for both drivers and law enforcement, while still allowing for comfort and protection from sunlight.
These limits mean that tint below 30% on your front side windows or rear window requires an Indiana medical exemption. ForeverTint helps you find out whether you qualify through a review by an independent licensed physician. If you qualify, keep the certification in your vehicle and renew it every year.
Traditionally, getting a tint exemption in Indiana meant making an in-person doctor’s appointment, explaining your condition, and handling paperwork yourself. ForeverTint streamlines this entire process online:

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 comply with Indiana law, the medical window tint certification must be completed and signed by a licensed physician or optometrist, and include:
This signed certification must be kept in your vehicle at all times. Presenting it shows your tint is covered by Indiana’s medical exemption, but it does not guarantee you will not be stopped or cited; officers retain discretion.
Indiana law does not accept verbal explanations as proof. The certification must be signed by a physician or optometrist licensed in Indiana. Without it, tint beyond the legal limit can result in a citation, even if your medical needs are legitimate.
Indiana Code Section 9-19-19-4(b): “This section does not apply to the driver of a vehicle: (1) that is owned by an individual required for medical reasons to be shielded from the direct rays of the sun; or (2) in which an individual required for medical reasons to be shielded from the direct rays of the sun is a habitual passenger. The medical reasons must be attested to by a physician or optometrist licensed to practice in Indiana, and the physician’s or optometrist’s certification of that condition must be carried in the vehicle. The physician’s or optometrist’s certificate must be renewed annually.”

Indiana’s tint limits do not apply to a vehicle owned by, or habitually carrying, a person who must be shielded from the direct rays of the sun for medical reasons. A physician or optometrist licensed in Indiana must certify the condition, and the certificate must be carried in the vehicle and renewed every year.
Yes, as long as a physician or optometrist licensed in Indiana evaluates you and certifies the medical need. ForeverTint connects you with an independent licensed physician who decides whether you qualify. Keep the certification in your vehicle and renew it every year.
If you don’t have your certification in the vehicle, law enforcement may treat your tint as illegal, even if you have a qualifying condition. Indiana law requires that documentation be carried at all times to verify your exemption. Failing to present it can lead to fines or additional penalties.
Indiana’s statute does not set a darkness limit for exempt vehicles, but the exemption depends on a current certification carried in the vehicle and renewed every year.
No, Indiana does not require you to file an application with the DMV for a tint exemption. Instead, the law requires a signed certification from a licensed physician or optometrist. This documentation acts as your legal authorization when carried in your vehicle.
An independent licensed physician reviews your medical history to confirm whether you need protection from the sun. If you qualify, you receive a certification that must be kept in your vehicle and renewed every year.
Qualifying conditions typically include those that require protection from direct sunlight, such as lupus, skin cancer, or severe light sensitivity. A licensed physician or optometrist must determine whether your condition meets the legal standard. The final decision is based on medical necessity and proper documentation.
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.
