Window tint laws in Alaska (2026)

The rules, window by window

Windshield

The front windshield may have a strip of tinting material applied to the top edge (industry term 'eyebrow') that does not extend downward more than 5 inches from the top of the glass.

Reflectivity

Mirrored tinting material is prohibited on any window of the vehicle; the regulation text obtained does not otherwise specify a numeric reflectance percentage limit separate from the mirrored-material ban.

Color restrictions

Tinting materials must be green, gray, bronze, or neutral smoke in color, or a sun-reflective auto film.

Medical exemption

A darker exemption is available where an occupant of the vehicle requires shielding from direct sun rays for medical reasons, certified in writing by a physician licensed in Alaska, with the certification renewed annually and carried in the vehicle.

Enforcement

Light transmittance is measured with a light-transmittance measuring device, with an allowance for manufacturing variance of plus or minus 3 percent.

Notes

The governing rule is an administrative regulation, 13 AAC 04.223 (Tinted vehicle windows), adopted under the general vehicle-equipment authority of AS 28.05.011, rather than a numbered Alaska Statute directly setting VLT percentages. Front side (driver/front passenger) windows require at least 70% light transmittance; rear door windows, quarter glass, and the back glass require at least 40%. Limousines and passenger buses used to transport persons for hire, motor homes, and vehicles the manufacturer identifies as multipurpose vehicles may instead comply with the federal glazing standard, 49 CFR 571.205 (1992), which can permit darker rear-of-vehicle tint than the 40% state floor. The regulation text obtained does not specify whether the percentage is measured as 'net' film-only transmittance or 'combined' glass+film transmittance; this was not resolved from the text available and should be treated as unverified. The official Alaska Legislature regulations portal (akleg.gov) could not be directly fetched in this research pass (blocked/format issue); the text above was cross-checked across two independent full-text reproductions of 13 AAC 04.223 (Cornell Legal Information Institute and Justia Regulations), both of which quote the same operative language, but neither is the primary akleg.gov instrument itself, so a human reviewer should confirm the current text on akleg.gov directly before publishing.
