VLT is the share of light the glass lets through, film and glass together. Source: K.S.A. 8-1749a, checked Nov 5, 2026. Laws change; confirm with the statute before tinting.

Kansas regulates window tint through K.S.A. 8-1749a. Below: the minimum visible light transmission (VLT) for each window, the windshield rule, what counts as too reflective, who can get a medical exemption, and how an officer checks a car at the roadside.

  • Front side windows: at least 35% VLT.
  • Back side windows: at least 35% VLT.
  • Rear window: at least 35% VLT.

VLT is measured through film and glass together. Factory glass already blocks some light, usually landing between 70% and 80% VLT before any film, so a roll sold as "35%" on a window that started at 75% ends up darker than 35% once installed. Officers meter the finished window, not the box the film came in.

Windshield

A nonreflective strip along the top only, not extending below the AS1 line, and not red, yellow or amber.

Federal standard FMVSS 205 sets the baseline for the glass itself: the windshield and front side windows of a new car must transmit at least 70% of visible light. State law decides what film may be added afterwards, which is why the windshield rule is usually a strip above the AS-1 line rather than a percentage.

Reflective and colored film

Film on every window must be nonreflective; the Highway Patrol treats any mirrored tint as illegal. Film colors not permitted: red, yellow, amber (windshield strip).

Medical exemptions

Kansas allows darker tint with a medical exemption. Only clear, colorless UV-blocking film with at least 78% transmittance is allowed, backed by a signed physician or optometrist statement; it does not permit darker tint.

Stickers, mirrors and enforcement

No sticker or certificate is required for legal tint. Tinting the rear window does not trigger a second-mirror requirement. Misdemeanor (K.S.A. 8-1749a(h)); the offense is not on the 8-2118 uniform fine schedule.

In practice

Kansas applies a single 35% floor to the front side, rear side and rear windows, measured as total transmission through film and factory glass combined. The statute states no tolerance. A driver cited without the medical statement has 60 days to produce it or show the film was removed, after which the citation is dismissed. Tinted headlamp covers are separately banned, and installing noncompliant film is itself unlawful.

Common questions about tint in Kansas

Is 35% tint legal on front windows in Kansas?

Yes. 35% is the darkest Kansas allows on front side windows: the glass and film together must let at least 35% of visible light through. Anything darker fails a meter check.

Can I tint my windshield in Kansas?

A nonreflective strip along the top only, not extending below the AS1 line, and not red, yellow or amber. Film below that line is not permitted for ordinary drivers.

Does Kansas allow darker tint for medical reasons?

Yes, with documentation. Only clear, colorless UV-blocking film with at least 78% transmittance is allowed, backed by a signed physician or optometrist statement; it does not permit darker tint.

What happens if my tint is too dark in Kansas?

Misdemeanor (K.S.A. 8-1749a(h)); the offense is not on the 8-2118 uniform fine schedule.

What we don't publish

No reviews, no star ratings, no "best installer" lists. Prices on shop profiles are entered by the owner and checked for format, not negotiated or verified by us; where a shop lists nothing, we say "Quote on request" rather than fill the gap. What a person at Armor Atlas does verify is that the shop exists, installs the service and answers the phone — and that check is dated on every listing.
