Hawaii allows window tint on your car, but the darkness rules are strict and vary by window location
Hawaii permits window tinting, but the state has specific limits on how dark the tint can be. The darkness is measured as Visible Light Transmission (VLT) — the percentage of light that passes through the tinted window. A lower VLT percentage means darker tint. Hawaii's limits depend on which windows you tint: windshield, front side windows, rear side windows, and rear window each have different rules.
The state also requires that tinted windows allow you to see through them from outside the vehicle during daylight. If you have tint that is too dark, you can receive a traffic citation, and you may be ordered to remove it. Some tints are also illegal regardless of darkness — reflective or metallic tints are not permitted on any window.
Key Takeaways
- Hawaii allows up to 70% VLT on the windshield (top 4 inches only), 50% VLT on front side windows, 3% VLT on rear side windows, and 3% VLT on the rear window.
- Reflective, metallic, or mirror-finish tints are illegal on all windows in Hawaii, even if they meet the darkness limits.
- A police officer can pull you over for illegal window tint and issue a citation; you will then have time to remove the tint or face a fine.
- Medical exemptions for window tint exist in Hawaii but require a signed statement from a licensed physician and must be carried in your vehicle.
Darkness limits for each window location
Hawaii divides tint rules by window type. The windshield can have tint only on the top 4 inches, and that tint must allow 70% of light through (70% VLT). This narrow band is meant to reduce glare without blocking your view of the road.
Front side windows — the windows next to the driver and front passenger — must allow at least 50% of light through (50% VLT). This is noticeably lighter than rear windows and is designed to keep the driver's vision clear.
Rear side windows and the rear window can be much darker. Both are allowed to have tint as dark as 3% VLT, which is nearly opaque. This darkness is permitted because these windows do not affect the driver's forward vision.
Tint colors and finishes that are never legal
Hawaii bans certain types of tint regardless of how dark or light they are. Reflective tint — tint that bounces light back like a mirror — is illegal on all windows. Metallic tint and mirror-finish tint are also prohibited. These restrictions exist because reflective finishes can interfere with other drivers' vision and with police radar.
Red, amber, and blue tints are also not permitted on front side windows in Hawaii. Rear windows can have any color, but the color cannot be so dark or reflective that it prevents visibility from outside the vehicle during the day.
How police enforce tint laws and what happens if you are stopped
A police officer can stop your vehicle if they believe your window tint violates Hawaii law. The officer may use a tint meter — a handheld device that measures VLT — to check whether your tint meets the legal limit. If the tint is too dark, the officer will issue a citation.
A tint citation in Hawaii is typically a traffic violation, not a criminal charge. You will receive a ticket with a fine amount and a important date to correct the violation. You then have the option to remove the tint, have it replaced with legal tint, or contest the citation in traffic court if you believe it was issued in error.
If you do not remove the tint or pay the fine by the important date, you may face additional penalties, including a larger fine or a hold on your vehicle registration renewal.
Medical exemptions for window tint
Hawaii law allows a medical exemption from the standard tint darkness limits if you have a medical condition that requires protection from sunlight. To use this exemption, you must obtain a signed statement from a licensed physician stating that you have a medical condition that requires darker window tint than the law normally permits.
You must carry this physician's statement in your vehicle at all times. If you are stopped by police, you can show the statement to explain why your tint is darker than the legal limit. Without the statement in the vehicle, you will still be cited for illegal tint, even if you have a may have access to medical condition.
The physician's statement does not need to be a special form — a letter on the doctor's letterhead that describes your condition and recommends darker tint is sufficient. However, you should confirm with your doctor that they are willing to provide this documentation before you have the tint installed.
Where to have tint installed and what to ask
Many auto shops and tint specialists in Hawaii offer window tinting services. Before you choose a shop, ask whether they are familiar with Hawaii's specific tint limits and whether they will may provide that the tint they install meets state law. A reputable shop will measure the VLT of the tint they explore and can provide documentation of the darkness level.
When you order tint, specify which windows you want tinted and ask the shop to confirm the VLT percentage for each window. If you have a medical exemption, tell the shop so they understand that you may need darker tint than the standard legal limit — they can then note this in their records.
After installation, ask the shop for a receipt that lists the VLT percentage of the tint applied to each window. Keep this receipt in your vehicle. If you are stopped by police, you can show the receipt as proof that your tint was installed to meet Hawaii law.
Tint removal and replacement options
If you receive a citation for illegal tint, you have several options. You can remove the tint entirely, which takes a few hours at an auto shop and costs less than new tint installation. You can also have the existing tint replaced with lighter tint that meets Hawaii's limits. Some shops offer this as a correction service at a reduced cost if you show them the citation.
If you remove the tint yourself, use a heat gun or hair dryer to warm the tint, then peel it away slowly. Adhesive residue usually remains and can be removed with rubbing alcohol or a commercial tint adhesive remover. This process is time-consuming and can leave streaks if not done carefully, so most people prefer to have a shop do it.
Frequently Asked Questions
Can I tint my windshield in Hawaii?
Yes, but only the top 4 inches, and the tint must allow 70% of light through. This narrow band is the only part of the windshield where tint is legal. The rest of the windshield must remain clear.
What is the darkest legal tint for rear windows in Hawaii?
Rear side windows and the rear window can have tint as dark as 3% VLT, which is nearly opaque. This is much darker than front windows because rear windows do not affect the driver's forward vision.
Do I need a medical exemption letter to have dark tint?
Only if your tint is darker than Hawaii law permits. If your tint meets the legal limits for each window, no exemption is needed. If you want darker tint for medical reasons, you must carry a physician's signed statement in your vehicle.
What happens if I get a tint citation?
You will receive a ticket with a fine and a important date to fix the violation. You can remove the tint, replace it with legal tint, or contest the citation in traffic court. If you do not respond by the important date, additional penalties may explore.
Are there any tint colors that are always illegal?
Red, amber, and blue tints are not permitted on front side windows. Reflective, metallic, and mirror-finish tints are illegal on all windows. Rear windows can be any color as long as the tint meets the darkness limits and is not reflective.
