Alaska Window Tint Laws (2026): Legal VLT Limits

Alaska regulates aftermarket window film under 13 AAC 04.223. Front side windows must still 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 take aftermarket film down to 40% VLT, and a separate federal-standard route applies to multipurpose vehicles, motor homes, limousines, and buses used for hire.

What is the legal tint limit in Alaska?

Alaska's window tint regulations are found at 13 AAC 04.223. The regulation is written around aftermarket material: subsection (a) bars driving with aftermarket tinting material or aftermarket striping material on any window except as the rest of the section allows, and subsection (b) then sets the levels aftermarket film may meet. That distinction matters, because factory privacy glass on many SUVs, vans, and pickups reads well below 40% VLT and is not aftermarket material.

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 aftermarket film that drops a front side window below that threshold is not allowed.

For windows behind the driver, including rear door windows, quarter glass, and the back glass, Alaska allows aftermarket film down to 40% VLT.

Alaska does treat one vehicle class differently. Under 13 AAC 04.223(b)(4), limousines and passenger buses used to transport persons for hire, motor homes, and vehicles identified by the vehicle manufacturer as multipurpose may instead have tinting material that complies with Standard No. 205, Glazing Materials, in 49 C.F.R. 571.205 (1992). Many SUVs, vans, and minivans are manufacturer-designated multipurpose passenger vehicles, so this alternative route to compliance covers a large share of the vehicles on Alaska roads.

There is also a narrow grandfather clause. Subsection (h) exempts a tinted rear window from these limits if the owner has proof that the rear window tinting was installed before July 1, 1994 and the vehicle is equipped with driver-side and passenger-side rearview mirrors.

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 the material restrictions. No tint is permitted on the main driving area of the windshield below that 5-inch strip.

Alaska prohibits mirrored tinting material on any vehicle window, including the windshield strip. Beyond the mirror ban, 13 AAC 04.223(d) sets out which materials are permitted: tinting material must be green, gray, bronze, or neutral smoke in color, or a sun reflective auto film. The regulation does not define which specific products fall into that last category, and the mirrored-material ban in subsection (a) applies regardless of which category a film is sold under.

This material rule is more specific than most states, so you cannot simply choose any dark film product. Confirm with your installer that the specific film they plan to use fits one of the categories named in 13 AAC 04.223(d) 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.

13 AAC 04.223(c) allows windows to have tinting that permits less light transmittance than the standard limits if three conditions are met: a driver or a passenger who frequently travels in the vehicle is required for medical reasons to be shielded from the direct rays of the sun, the medical reasons are certified annually by a physician licensed to practice in Alaska, and the certification is carried in the vehicle.

The in-state licensing requirement is easy to miss. The regulation calls for a physician "licensed to practice in this state," so a certification signed by an out-of-state physician does not meet its terms. If you move to Alaska with a medical tint exemption from another state, obtain a new certification from an Alaska-licensed physician.

"Annual" matters too: 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 plus-or-minus 3% figure is not an informal enforcement courtesy or a matter of interpretation. 13 AAC 04.223(e) builds it into the measurement itself: light transmittance must be measured using a light transmittance measuring device, with an allowance for manufacturing variances of plus or minus three percent, and the device's accuracy must be certified by its manufacturer. In practice, that allowance is part of the standard rather than an exception to it.

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 material and VLT rules.

Because Alaska limits tinting material to the categories in 13 AAC 04.223(d), make sure any receipt or product documentation identifies the specific film product and its listed category so you can demonstrate compliance if needed.

Penalties for illegal tint in Alaska

A window tint violation in Alaska is an infraction, not a crime. AS 28.90.010(c) provides that a person convicted of violating a regulation adopted under Title 28 is guilty of an infraction punishable by a fine not to exceed $300. AS 28.90.010(d) adds that an infraction is not a criminal offense, cannot result in imprisonment, does not by itself cost you your driver's license, and does not carry a right to a jury trial or court-appointed counsel.

The amount is set statewide, not by each jurisdiction. Administrative Rule 43.1, the Traffic Bail Forfeiture Schedule adopted by the Alaska Supreme Court under AS 28.05.151, lists "13 AAC 04.223 Tinted windows" as "Corr/150": a $150 bail forfeiture that can be paid without a court appearance. If you do appear in court and are convicted, the penalty imposed may not exceed that scheduled amount.

The "Corr" designation is the part most drivers need to know. Under Rule 43.1, a citation for an offense listed as "Corr" must be dismissed or voided if proof of correction is presented to an inspection official within the time allowed. Remove or replace the non-compliant film, have the correction verified, and the citation goes away. If the required repair is not made, the offense can be disposed of without a court appearance by forfeiting the $150.

One caveat on where you are stopped: Rule 43.1 doubles the listed bail amounts for Title 28 violations committed within a designated highway work zone or traffic safety corridor.

If you want to tint your windows in Alaska

Alaska's 70% minimum on front side windows is strict, and many standard aftermarket tint films are far darker than that. The practical result is that very little visible aftermarket 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: aftermarket film down to 40% VLT is allowed and provides meaningful heat and glare reduction. Choose a film that fits one of the material categories in 13 AAC 04.223(d): green, gray, bronze, neutral smoke, or a sun reflective auto film. If your vehicle is a motor home, or one the manufacturer identifies as a multipurpose vehicle, ask whether the federal Standard No. 205 route in subsection (b)(4) applies to it instead.

Use a licensed installer familiar with Alaska regulations. Ask for the specific product name and confirm its material classification. If you have a medical need for darker front-window tint, obtain the certification from an Alaska-licensed physician before installation and plan to renew it annually. Keep all documentation, including the product receipt and any medical certification, in the vehicle.
