Alaska window tint laws require front side windows to allow at least 70% VLT and rear side and back windows to allow at least 40% VLT. The windshield may only carry a non reflective strip on the top 5 inches. A tinted window violation is a correctable infraction with a $150 bail amount that can be dismissed if the tint is fixed. This guide covers who the rule applies to, medical exemptions, penalties, and exceptions. The controlling source is Alaska Administrative Code Section 13 AAC 04.223.

What Alaska Law Says About Window Tint
Alaska Administrative Code Section 13 AAC 04.223 sets the statewide rule for aftermarket window tint. A driver may not operate a motor vehicle with mirrored tinting material on any window. Outside of that ban, aftermarket tint is allowed only within specific limits for each window position. The Alaska Administrative Code 13 AAC 04.223 tinted vehicle windows regulation sets out these limits in full detail.
The windshield may carry a strip of tinting material along the top edge only, known in the industry as an eyebrow. This strip cannot extend more than 5 inches down from the top of the glass. No other part of the windshield may be tinted under state law. This rule applies uniformly across passenger cars, trucks, and other standard vehicle types statewide.
The driver and front passenger side windows must allow at least 70% light transmittance. This is one of the stricter front window standards among United States tint laws. The rear door windows, quarter glasses, and back glasses have a separate and lower minimum, requiring at least 40% light transmittance. Both figures are measured as net VLT through the combined glass and film.
Tinting materials permitted under Alaska law must be green, gray, bronze, or neutral smoke in color, or a sun reflective auto film. Materials outside these approved colors do not meet the regulation regardless of their VLT rating. Reflectivity is treated as a separate requirement from color and darkness, meaning a film in an approved color can still fail the rule if it produces a mirrored or metallic appearance.
Understanding VLT and Net VLT
VLT stands for visible light transmittance, defined under Alaska Administrative Code Section 13 AAC 04.223 subsection f as the ratio of total light passing through a window to the total light striking that window, expressed as a percentage. A higher VLT percentage means more light passes through and the tint is lighter. A lower VLT percentage means less light passes through and the tint is darker.
Net VLT is the reading that actually matters for compliance. It reflects the combined effect of the factory glass and any aftermarket film layered on top of it, not the film manufacturer’s printed percentage alone. A film box labeled 40% does not guarantee a 40% reading once installed, since factory glass already reduces some light transmittance before the film is added.
Light transmittance must be measured using a light transmittance measuring device, and the regulation builds in an allowance for manufacturing variances of plus or minus 3%. This variance exists to account for instrument accuracy, not to give drivers extra room to install darker tint. A reading a few points below 70% or 40% due to equipment tolerance is treated differently than a film chosen specifically to sit near that lower edge.
Who These Rules Apply To
The tint rules under Alaska Administrative Code Section 13 AAC 04.223 apply broadly to any motor vehicle driven on a highway, public road, street, or parking lot within the state. Standard passenger vehicles, including sedans, must follow the base windshield, front window, and rear window limits described above without any separate carve out for vehicle type.
Limousines, passenger buses used to transport people for hire, motor homes, and vehicles identified by the manufacturer as multipurpose vehicles are treated differently. These vehicle types may use tinting material that complies with Standard No. 205, Glazing Materials, under 49 CFR Section 571.205 as it existed in 1992. This federal glazing standard is incorporated directly into the state regulation rather than existing as a competing rule.
This carve out generally reflects why many SUVs and vans come from the factory with darker rear glass than the 40% state minimum would otherwise allow for aftermarket film. Factory installed glazing on a manufacturer designated multipurpose vehicle is evaluated under the federal standard referenced in the regulation, while aftermarket film added later on any vehicle type is still evaluated under the state VLT percentages described above.
Anchorage Municipal Tint Rule
Drivers in Anchorage face an additional layer of regulation beyond the statewide rule. The Alaska DMV road test equipment guidance page states that mirrored tinting material or aftermarket tint is illegal both under the state regulation, Alaska Administrative Code Section 13 AAC 04.223, and under the Municipality of Anchorage’s own ordinance, Anchorage Municipal Code Section 09.36.045.
This means a vehicle driven within Anchorage may be subject to both the state administrative code and the municipal code at the same time. A driver based in another part of Alaska is generally subject only to the statewide rule. Readers who drive primarily in Anchorage should treat the municipal layer as a separate, additional compliance point rather than assuming the state rule alone covers every situation there.
Medical Exemption Requirements
Alaska Administrative Code Section 13 AAC 04.223 subsection c allows tinting material that permits less light transmittance than the standard minimums when a driver or a passenger who frequently travels in the vehicle requires shielding from direct sunlight for medical reasons. This exemption applies to the front and rear window minimums, not to the windshield eyebrow strip restriction.
To qualify, the medical reason must be certified annually by a physician who is licensed to practice in Alaska. The certification itself must be carried in the vehicle at all times, since it serves as the documentation that supports a lower VLT reading during a stop. The regulation does not specify a fixed alternate percentage for medical exemption cases, unlike some other states.
Because the certification requirement is renewed annually and depends on the physician’s assessment of a specific medical condition, drivers considering this option often benefit from confirming current requirements directly with a licensed attorney in your state or with official Alaska sources before installing tint darker than the standard limits. Details of what qualifies as a valid medical reason can vary by individual circumstance.
Penalties for Illegal Window Tint
A tinted window violation under Alaska Administrative Code Section 13 AAC 04.223 is classified as an infraction under Alaska Statute Section 28.90.010 subsection c. According to the Alaska Court System Vehicle and Traffic Offenses Booklet, this offense carries a bail amount of $150 and is listed as a correctable offense.
A correctable offense gives the driver an option beyond simply paying the fine. If the driver shows proof that the illegal tint has been corrected, the citation can be dismissed entirely under Alaska’s Administrative Rule 43.1 and the Minor Offense Rules governing correctable citations. This distinguishes a tint violation from many other traffic offenses that carry a fixed penalty with no correction based dismissal path.
Bail amounts under Alaska’s traffic offense schedule can be doubled for violations that occur within a designated highway work zone or traffic safety corridor. A driver who requests a trial and is found guilty generally faces a maximum fine equal to the scheduled bail amount plus any applicable surcharge, rather than a higher court imposed penalty, since the bail schedule caps the maximum for offenses at this classification.
Exceptions and Grandfathered Tint
Alaska Administrative Code Section 13 AAC 04.223 subsection h provides a grandfather exception for certain older rear window tint. A tinted rear window is exempt from the standard tinting rules if the vehicle owner has proof that the rear window tinting was installed before July 1, 1994, and the vehicle is equipped with both driver side and passenger side rearview mirrors.
This exception exists because the regulation set July 1, 1994 as the statewide compliance deadline under subsection g, meaning all vehicles had to meet the current standards by that date going forward. Tint installed before that deadline on a rear window, paired with proper mirrors to compensate for reduced rear visibility, can remain in place without being treated as a new violation of the current percentages.
The regulation’s history shows it became effective October 2, 1992, and was amended April 2, 1994 and again February 8, 1998. The version reviewed for this guide is current through February 24, 2025 according to the Alaska Administrative Code. This effective date history explains why the grandfather clause is tied specifically to the 1994 compliance deadline rather than a more recent date.
Pending Legislation Is Not Current Law
Two bills before the Alaska State Legislature would change how window tint is regulated if enacted, but neither had passed as of this guide’s most recent verification. The Alaska State Legislature House Bill 211 text proposes moving tint rules out of the administrative code and into Alaska Statutes Section 28.35.271, with a rear window minimum of 35% light transmittance instead of the current 40%.
A separate proposal, Senate Bill 78, would create a distinct crime of improper installation of window tinting, aimed specifically at installers rather than vehicle owners, and would classify that offense as an infraction. Because neither bill has been enacted, the current controlling rule for both installers and drivers remains Alaska Administrative Code Section 13 AAC 04.223 as described throughout this guide.
Readers should treat any online source describing a 35% rear window minimum, or a separate installer specific tinting crime, as describing proposed rather than current Alaska law unless that source confirms the bill has since passed. Laws and enforcement may change, so checking official state sources for the latest rules is a reasonable step before relying on any specific percentage for a purchase or installation decision.
Common Misconceptions About Alaska Tint Law
A common misconception is that the 3% meter variance built into Alaska Administrative Code Section 13 AAC 04.223 lowers the real legal minimum to 67% for front windows and 37% for rear windows. The variance exists solely to account for measuring device tolerance during enforcement, not to establish an intentionally darker installation target that a driver can rely on as a safe margin.
Another misconception involves factory tinted glass on SUVs and vans. Some drivers assume any factory rear glass darker than 40% must be illegal, when in fact manufacturer designated multipurpose vehicles are evaluated under the federal glazing standard referenced in subsection b of the regulation rather than the aftermarket percentages that apply to added film. For questions about how these rules apply to a specific vehicle or citation, consulting a licensed attorney in your state remains the appropriate step, and readers can review the full Disclaimer for more on the limits of this informational guide.
