A window tint exemption in Idaho allows you to legally apply window tint that would otherwise violate the state’s standard tint limitations, particularly on front side windows and certain windshield restrictions. This exemption is especially important for drivers with medical conditions that make them sensitive to sunlight or UV exposure. Without it, having darker tint on restricted windows could result in citations or other legal issues during a traffic stop. With proper medical documentation, however, it becomes a legally recognized medical accommodation under Idaho law.
The exemption qualification process involves two parts:
Some people ask whether an Idaho medical exemption lets them tint their windows as dark as they want. The answer is no. With physician verification, Idaho allows nonreflective tint of at least 70% light transmission on the windshield and at least 20% on the other windows, each plus or minus 3%, with reflectance of no more than 35%.
It’s important for all Idaho drivers to understand the state’s window tint laws, even if you do not currently qualify for a Medical Window Tint Exemption. Idaho has specific guidelines that regulate how dark your vehicle windows can be tinted. These laws are intended to balance driver visibility and law enforcement safety while still allowing reasonable levels of privacy and heat protection.
These limits mean that tint darker than the standard limits, especially on your front side windows or windshield, requires an Idaho medical exemption. ForeverTint helps you find out whether you qualify through a review by an independent licensed physician. If you qualify, your physician’s written verification lets you use tint within the medical limits set by Idaho Code Section 49-944(4).
Traditionally, getting a tint exemption in Idaho 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.
Under Idaho Code Section 49-944(4), you need written verification from a licensed physician that you, as the driver or a passenger, must be protected from exposure to sunlight or heat for medical reasons associated with past or current treatment. The verification must be carried in the vehicle.
Keep this verification in your vehicle at all times. Presenting it shows your tint is covered by Idaho’s medical exemption, but it does not guarantee you will not be stopped or cited; officers retain discretion.
Idaho law does not rely on verbal explanations alone when it comes to medical window tint exemptions. Your exemption should be supported by properly documented physician verification that clearly explains the medical necessity for darker window tint. Without this documentation, any tint beyond Idaho’s legal limits, especially on front side windows or windshield areas, could result in a citation even if your medical condition legitimately requires additional sun protection.
Idaho Code Section 49-944(4): “Nonreflective window tinting film or sunscreening devices that have a light transmission of not less than seventy percent (70%) plus or minus three percent (3%) for the front windshield and not less than twenty percent (20%) plus or minus three percent (3%) for the windows, with a luminous reflectance of no more than thirty-five percent (35%) plus or minus three percent (3%) in each instance, is permitted for a motor vehicle operated by, or carrying as a passenger, a person who possesses written verification from a licensed physician that the operator or passenger must be protected from exposure to sunlight or heat for medical reasons associated with past or current treatment; such written verification shall be carried in the vehicle.”

Idaho allows darker tint for a vehicle driven by, or carrying, a person with written verification from a licensed physician that they must be protected from sunlight or heat for medical reasons associated with past or current treatment. The verification must be carried in the vehicle, and tint must stay within the medical limits: at least 70% on the windshield and 20% on the other windows.
Yes, as long as a licensed physician reviews your medical history and provides the written verification Idaho requires. ForeverTint connects you with an independent licensed physician who decides whether you qualify.
If your vehicle has tint darker than Idaho’s legal limits and you cannot provide physician verification supporting your exemption, law enforcement may issue a citation. That is why it is important to keep a printed copy of your medical tint exemption documentation in your vehicle at all times.
No. With physician verification, Idaho still requires at least 70% light transmission on the windshield and at least 20% on the other windows (each plus or minus 3%), with reflectance of no more than 35%.
No. Idaho does not require a DMV application or state permit for the medical exemption. Keep your physician’s written verification in the vehicle and present it if requested.
An independent licensed physician reviews your medical history by chart review or, occasionally, a brief phone call. If you qualify, you receive the written verification Idaho requires.
Conditions involving sensitivity to sunlight or heat that relate to past or current medical treatment may qualify, such as lupus, albinism, photosensitivity disorders, or melanoma. A licensed physician decides whether you qualify.
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.
