Alaska Window Tint Laws (2026): Legal VLT Limits
Alaska Window Tint Laws (2026): Legal VLT Limits
Alaska law requires front side windows to allow at least 70% of visible light through, making it one of the strictest front-window rules in the country. Rear door windows, quarter glass, and the back window may be tinted to 40% VLT.
What is the legal tint limit in Alaska?
Alaska's window tint regulations are found at 13 AAC 04.223. The law sets a strict 70% VLT minimum on front side windows for all vehicles. Before going further, here is the key concept: a higher VLT percentage means lighter (less tinted) film, while a lower VLT percentage means darker film. So 70% is very light, close to factory glass on most vehicles, and any film that drops below that threshold on the front side windows is illegal.
For windows behind the driver, including rear door windows, quarter glass, and the back glass, Alaska allows film down to 40% VLT. Alaska does not appear to distinguish between passenger cars and multi-purpose vehicles (SUVs/vans/trucks) for these rear positions; the 40% rule applies generally.
| Window | All Vehicles |
|---|---|
| Front side windows | 70% VLT minimum |
| Back side windows (rear doors/quarter glass) | 40% VLT minimum |
| Rear window (back glass) | 40% VLT minimum |
| Windshield | Top-edge strip only, max 5 inches down |
Windshield tint rules in Alaska
Alaska permits a tint strip along the top edge of the windshield, but it cannot extend more than 5 inches down from the top. This strip is intended as a sun visor aid and must comply with color restrictions. No tint is permitted on the main driving area of the windshield below that 5-inch strip.
Alaska prohibits mirrored material on any vehicle window, including the windshield strip. Beyond the mirror ban, Alaska specifies which tint colors are actually permitted: film must be green, gray, bronze, or neutral smoke. Any other color, including blue, red, amber, or purple, is not permitted on Alaska vehicles.
This color rule is more specific than most states and means you cannot simply choose any dark film product. Confirm with your installer that the specific film they plan to use falls within the permitted color range before installation.
Medical exemptions
Alaska offers a medical exemption for drivers who need additional protection from sunlight due to a qualifying medical condition. Common qualifying conditions include photosensitivity disorders, lupus, skin conditions requiring UV protection, and certain eye conditions.
To qualify, you need an annual certification from a licensed physician. "Annual" is important: unlike some states where a one-time certificate suffices, Alaska requires you to renew the documentation each year. You must carry the current physician certification in your vehicle at all times so you can present it to law enforcement during a traffic stop.
If your certification has lapsed, an officer is entitled to cite you even if you have a genuine medical need. Mark your calendar to renew the physician certification before it expires each year.
How tint is measured and certified
Alaska uses a VLT meter to measure the percentage of visible light passing through a window during enforcement. The state's practical tolerance is plus or minus 3%, so a front side window measuring 67% on a meter could still be within the spirit of the 70% minimum under that tolerance, though any reading below 70% is technically a violation.
Alaska does not require a compliance sticker or installer label on the vehicle. That said, keeping a receipt or installer certificate in your glove box is a good practice if you are ever questioned about whether your tint complies with the color and VLT rules.
Because Alaska restricts tint colors to green, gray, bronze, and neutral smoke, make sure any receipt or product documentation identifies the specific film product and its listed color category so you can demonstrate compliance if needed.
Penalties for illegal tint in Alaska
A window tint violation in Alaska is classified as an infraction, which is a civil rather than criminal matter. Infractions do not carry jail time and result in a fine. The specific fine amount can vary by jurisdiction and is set under Alaska's infraction schedule.
While an infraction is less serious than a misdemeanor, it still results in a fine and may require you to correct the violation within a specified period. Continuing to drive with non-compliant tint after receiving a citation could lead to additional infractions.
If your tint violates the color restriction (using a prohibited color such as blue or red) in addition to the VLT minimum, you may face separate findings for each violation.
If you want to tint your windows in Alaska
Alaska's 70% minimum on front side windows is strict, and many standard after-market tint films are far darker than that. The practical result is that very little visible tinting is legal on Alaska front side windows. Most factory-installed glass already transmits around 70-75% VLT, so any film applied will reduce that figure and push it close to or below the legal limit.
For the back side windows and rear glass, you have more flexibility: film down to 40% VLT is legal and provides meaningful heat and glare reduction. Choose a film in one of the four permitted color categories: green, gray, bronze, or neutral smoke.
Use a licensed installer familiar with Alaska regulations. Ask for the specific product name and confirm its color classification. If you have a medical need for darker front-window tint, obtain the physician certification before installation and plan to renew it annually. Keep all documentation, including the product receipt and any medical certification, in the vehicle.
