Understanding Hawaii Window Tint Laws

In understanding Hawaii's window tint laws, it's crucial to know that while non-reflective window tint is allowed on the top 4 inches of the windshield, the front and rear side windows must allow more than 35% of light to pass through, and metallic tints are strictly forbidden. This is part of the Window Tint Rules which dictate the Visible Light Transmission (VLT) through your vehicle's windows.

The Hawaii window tint law emphasizes on the percent of visible light permitted to pass through your vehicle's windows. The law is specific about the front side windows: they must allow more than 35% of light in. Similar rules apply to the rear side windows and the rear windshield. This is referred to as tint darkness.

Now, you might be wondering about exceptions. Does Hawaii allow medical exemptions for window tinting? Yes, it does. If you have a medical condition that necessitates darker tint, you can apply for a Medical Exemption for Window Tinting. This involves completing a Medical Exemption Affidavit.

Medical Conditions Eligible for Exemption

Now that you're familiar with Hawaii's window tint laws, let's look at the medical conditions that can make you eligible for an exemption. These conditions primarily involve sensitivity to light and UV rays and include a range of skin and eye disorders.

Firstly, if you suffer from light sensitivity and photophobia - an intense intolerance to light - you may qualify for a window tint exemption. This also applies to certain skin conditions that react negatively to sunlight. Therefore, if you have a diagnosis of lupus or skin cancer, which both necessitate protection from UV rays, you could be eligible too.

Eye disorders like cataracts can also make you a candidate for an exemption. Cataracts cause clouding of the eye lens, leading to blurred vision and increased sensitivity to glare. Tinted windows can provide relief from harsh sunlight and improve visibility.

Moreover, albinism, a condition marked by the lack of melanin, leading to light skin and hair, and heightened sensitivity to the sun, can also qualify you for an exemption. Similarly, autoimmune diseases, which can cause light sensitivity and skin problems, may also make you eligible.

Procedure for Obtaining Medical Exemption

To get a medical exemption for window tint in Hawaii, you'll first need to secure a note from a local doctor detailing your specific medical condition that necessitates darker window tint. It's essential that the doctor's note clearly specifies the level of tint required based on your medical condition.

Next, it's time to get the medical exemption forms. You can obtain these from your local DMV office. Make sure to fill out these forms completely, providing all the necessary information. Clear and detailed answers will help speed up the process. The forms will ask for details about:

Your specific medical condition
The level of tint recommended by your doctor
The specific windows that require tinting

Once you've completed the forms, return them to your local DMV office for official registration. This part of the process is crucial. Only after official registration of your completed forms will you be allowed to have darker window tint than normally permitted by law.

After your forms are registered, you'll receive a window tint sticker or certificate for display. This is proof of your medical exemption and must be displayed according to the display requirements.

Benefits of Medical Window Tint Exemption

Once you've secured your medical exemption for window tinting, you'll start experiencing the benefits that come with it, especially if you're someone with light-sensitive conditions. This darker tint, permitted due to your documented medical conditions, can significantly enhance your comfort and reduce the harmful effects of sunlight.

Firstly, the darker tint allowed by your medical exemptions can provide much-needed relief from sun glare and heat. This is particularly beneficial if you have light-sensitive conditions such as photophobia or lupus. Not only does this increase comfort, but it also improves safety by reducing the blinding effect of sunlight while driving.

Secondly, this legal allowance offers peace of mind. You can enjoy the benefits of darker window tint without worrying about running afoul of Hawaii's tint laws. Remember, it's crucial to keep the exemption certificate issued by the DMV visible on your tinted windows to avoid any legal problems.

Maintaining this legal allowance, however, requires renewal. In most cases, you'll need to renew your medical exemption annually at the DMV. This ensures you continue to enjoy the benefits of your window tint legally.

Lastly, this exemption can increase your privacy. The darker tint makes it harder for outsiders to see into your vehicle, offering you an extra layer of security.

Visible Light Transmission (VLT)

Hawaii tint limits — standard vs. medical exemption

Window	Standard (Haw. Rev. Stat. § 291-21.5)	With medical exemption
Windshield	AS-1 line	Doctor may authorize full non-reflective tint below the AS-1 line when photosensitivity is documented.
Front side windows	35% minimum light transmission	Typically 20%–35% VLT when clinically justified (statute ceiling applies).
Rear side windows	Most states permit any darkness on rear sides	No change — medical exemption rarely needed here.
Rear window	Most states permit any darkness when dual side mirrors are present	No change — already covered by the dual-mirror provision.
Reflectivity	Generally capped at 20%–35%; mirrored / metallic tint prohibited	Same — medical exemption does not permit reflective film.

Numbers in the Standard column reflect Hawaii's baseline statute. The With medical exemption column describes the typical range a clinician can prescribe; the final VLT authorized is whatever the physician's letter or state-issued exemption certificate specifies, subject to the statute's ceiling. Always match the installed film to the exemption document — the exemption only covers the darkness specifically justified by the clinician.

At A Traffic Stop

What Hawaii law enforcement looks for

Officers in Hawaii typically run a tint-meter reading at the driver's window and then ask for exemption paperwork before writing a citation. Produce these three items immediately and the stop usually ends with a warning rather than a fine:

1 The physician's signed exemption letter or Hawaii exemption certificate — original, not a photocopy. The letter must identify the condition (photophobia, lupus, post-corneal-surgery sensitivity, melanoma history, etc.) and the maximum VLT the clinician authorizes.
2 The clinician's NPI number and state license on the letterhead. undefined officers can verify an NPI against the federal NPPES registry in seconds.
3 A tint-card or installer invoice showing the VLT of the installed film. When the installer's VLT is at or above what the exemption authorizes, the stop is usually dismissed on the spot.

Note: Hawaii officers cannot demand to see your underlying medical record — only the signed exemption document. HIPAA protects the diagnosis detail; the exemption letter is the only document they are legally entitled to review during a traffic stop.

Keeping Your Exemption Valid

How to stay compliant in Hawaii

• Keep the original exemption document in the glove box at all times — not the trunk, not a phone photo. Most Hawaii officers will not accept a digital copy.
• If the vehicle changes hands, the exemption does not transfer. Remove the tint or secure a new exemption for the new driver.
• Re-verify the exemption annually with undefined — a few states require an updated physician's letter every 1–3 years. If your documentation is more than 24 months old, refresh it.
• Match the installed film exactly to the VLT authorized by the clinician. Going darker than the letter permits voids the exemption and exposes you to the full statute penalty.
• Keep the installer's receipt showing the VLT of the film. Independent verification of the installed tint is the single most common question officers ask after they see the exemption letter.
• If you move out of Hawaii, you will need to obtain a new exemption under your new state's statute. Exemptions are not portable across state lines.

Common Questions

Hawaii Window Tint Medical Exemption FAQs

What is the law on window tint medical exemptions in Hawaii?

The governing statute in Hawaii is Haw. Rev. Stat. § 291-21.5, administered by Hawaii Department of Transportation. The default front-side visible-light-transmission (VLT) rule is 35%, with windshield tint limited to AS-1 line. A medical exemption allows darker tint than the baseline when a licensed physician certifies the medical necessity.

How do I apply for a window tint medical exemption in Hawaii?

In Hawaii, you submit a signed physician letter on letterhead to Hawaii Department of Transportation. The certification must come from a licensed physician, optometrist, or ophthalmologist and identify the condition creating medical necessity (photophobia, lupus, post-cataract sensitivity, etc.). MyEyeRx handles the virtual consultation and issues the Hawaii-compliant documentation after the visit when medically appropriate.

What do I need to keep in my vehicle in Hawaii?

Hawaii exemption requires a certificate of exemption signed by a licensed physician. Keep a copy of the signed documentation, the physician's contact information, and the statute reference (Haw. Rev. Stat. § 291-21.5) in the glove box so you can produce it during a traffic stop. Hawaii drivers are strongly encouraged to carry the original — not a photocopy — because some inspection officers will not accept copies.

Is an online / telehealth appointment valid for a Hawaii tint exemption in 2026?

Yes. Hawaii accepts a telehealth consultation with a U.S.-licensed optometrist, ophthalmologist, or physician as the basis for the exemption documentation, provided the clinician conducts the visit in accordance with Hawaii telemedicine rules. MyEyeRx's 2026 process is 100% virtual and the paperwork is formatted for Hawaii Department of Transportation.

How much darker can I go with a Hawaii medical exemption?

Hawaii's non-medical VLT rule is 35% on the front sides. With a valid medical exemption, drivers typically run much darker tint (commonly 20%–35% on the front sides) depending on the physician's recommendation and the statute's ceiling. Always match the installer's film to the VLT the exemption letter permits; the exemption only covers the darkness specifically justified by the clinician.
