Alaska window tint laws require front side windows to allow at least 70% VLT and rear windows to allow at least 40% VLT. A confirmed violation is a correctable infraction with a $150 bail amount under state court records. The windshield permits only a narrow non reflective strip along the top edge. This guide also covers vehicle types, exemptions, and Anchorage enforcement under Alaska Administrative Code Section 13 AAC 04.223.
Key Terms Defined
Visible Light Transmission, known as VLT, is the percentage of light that passes through a vehicle window. A higher percentage means a clearer window and a lower percentage means a darker one. Alaska law sets separate minimum VLT percentages for different windows on a vehicle. Understanding this single measurement is the starting point for understanding every other rule that follows in the state regulation.
VLT and Net VLT Explained
Net VLT is the real number that matters under Alaska law. It reflects the combined effect of factory glass and any aftermarket film applied on top of it, not the percentage printed on a film label. A film rated 50% installed over tinted factory glass can test well below 40% once measured together. This is why tint sometimes fails inspection even when the film package claimed compliance.
What the Law Says
Alaska Administrative Code Section 13 AAC 04.223 sets the statewide standard for aftermarket window tinting. The regulation took effect October 2 1992 and was amended February 8 1998. It remains the controlling rule for vehicles operated on Alaska highways, public roads, streets, and parking lots. The rule addresses the windshield, the front side windows, the rear side windows, the rear window, and permitted tint colors separately.
Windshield Rule
The front windshield may carry a strip of tinting material along its top edge, commonly called an eyebrow strip in the industry. That strip cannot extend more than five inches downward from the top of the glass. The material used for this strip must be non reflective. No other tint of any kind is permitted anywhere else on the windshield under the current state regulation.
Front Side Window Rule
The driver window and the front passenger window must permit at least 70% VLT under Alaska Administrative Code Section 13 AAC 04.223. This is one of the stricter front window standards nationally, since many states permit noticeably darker front tint. Because most factory windshields and front windows already sit close to this threshold, adding any aftermarket film to these windows will often push them below the legal minimum.
Rear Side Window and Rear Window Rule
Rear door windows, quarter glasses, and the back glass must permit at least 40% VLT under the same state regulation. This 40% threshold is meaningfully more permissive than the 70% required for front windows. Vehicle owners should note that this rule applies to rear glass on standard passenger cars, while a separate provision addresses multipurpose vehicles differently later in this guide.
Color and Reflectivity Restrictions
Alaska Administrative Code Section 13 AAC 04.223 subsection d limits permitted tint colors to green, gray, bronze, or neutral smoke, or a sun reflective auto film meeting the standard. Mirrored or metallic tinting material is prohibited on any window under subsection a of the same regulation. This color rule applies separately from the VLT rule, meaning a compliant VLT percentage in a prohibited color is still a violation.
Who It Applies To
Alaska Administrative Code Section 13 AAC 04.223 applies broadly to any motor vehicle driven on a highway, public road, street, or parking lot within the state. The rule does not distinguish between residents and visitors, meaning vehicles registered in other states are still subject to Alaska law while operating there. Certain vehicle categories receive distinct treatment under subsection b of the regulation, described in the following subsections.
Passenger Vehicles
Standard passenger cars, including sedans and similar vehicles, must meet the 70% VLT front window standard and the 40% VLT rear window standard described above. These percentages apply uniformly regardless of the vehicle’s make or model. There is no separate lighter standard for passenger vehicles compared with the general rule stated in Alaska Administrative Code Section 13 AAC 04.223 subsection b.
Multipurpose Vehicles, Limousines, and Buses
Limousines and passenger buses used to transport persons for hire, along with motor homes and vehicles the manufacturer identifies as multipurpose, may instead use tinting material that complies with federal Standard No. 205 for glazing materials under 49 C.F.R. 571.205. This creates a distinct compliance path for these vehicle categories rather than requiring them to meet the standard passenger vehicle VLT percentages described earlier in this guide.
Requirements or Elements
Measurement Tolerance
Alaska Administrative Code Section 13 AAC 04.223 subsection e allows a tolerance of plus or minus 3% when using a certified light transmittance measuring device. This tolerance accounts for instrument accuracy during enforcement, not extra room to install darker tint intentionally. A front window reading 67% falls within tolerance of the 70% requirement, but the rule does not lower the standard itself to 67%.
Penalties or Consequences
Statewide Bail Amount
According to the Alaska Court System’s Vehicle and Traffic Offenses Booklet, a violation of Alaska Administrative Code Section 13 AAC 04.223 is a correctable infraction with a bail amount of $150. The penalty section for this offense is Alaska Statutes Section 28.90.010 subsection c. Because the offense is correctable, a driver may have the citation dismissed by fixing the tint and providing proof to an inspecting official.
Anchorage Municipal Enforcement
The Municipality of Anchorage enforces its own parallel window tinting rule under Anchorage Municipal Code Section 9.36.045, in addition to the statewide regulation. This municipal ordinance sets the same 70% front window and 40% rear window thresholds confirmed by the Anchorage Police Department window tint FAQ. Drivers within Anchorage should understand that municipal enforcement operates under a separate code section from the statewide regulation described earlier.
Exceptions and Limitations
Medical Exemption
Alaska Administrative Code Section 13 AAC 04.223 subsection c permits darker tinting material than the standard VLT limits when a driver or frequent passenger needs shielding from direct sunlight for medical reasons. The medical reason must be certified annually by a physician licensed in Alaska. That certification must be carried in the vehicle to support the exemption if the vehicle is stopped for a tint check.
Common Misconceptions
Film Percentage vs. Net VLT
A common misconception is that the percentage printed on a window film package tells a driver whether their car is legal. Alaska law measures net VLT through the factory glass and the film together, not the film rating alone. A driver installing 50% film onto tinted factory glass can end up with a combined reading below the 40% rear window minimum, even though the label suggested compliance.
Pending Legislation Is Not Yet Law
Alaska lawmakers have introduced Senate Bill 51 and Alaska House Bill 211 pending window tinting legislation, which would add a new section to Alaska Statutes and could set a 35% rear window minimum instead of the current 40% standard. Neither bill has been enacted as of this guide’s most recent verification. Laws may change, so drivers should check official state sources for the latest confirmed rules.
Drivers researching this topic should rely on the Alaska Administrative Code Section 13 AAC 04.223 full text for the complete regulation language. The Alaska Court System Vehicle and Traffic Offenses Booklet confirms the official statewide bail schedule, and Anchorage drivers can consult the Anchorage Municipal Code Section 9.36.045 on window tinting for local rules.
