VLT is the share of light the glass lets through, film and glass together. Source: 47 O.S. §12-422, checked Nov 5, 2026. Laws change; confirm with the statute before tinting.
Oklahoma regulates window tint through 47 O.S. §12-422. 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.
Legal tint limits in Oklahoma
- Front side windows: at least 25% VLT.
- Back side windows: at least 25% VLT.
- Rear window: at least 25% 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
Only a strip above the AS-1 line or within the top 5 inches, whichever is closer to the top; it may not be red 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
Luminous reflectance may not exceed 25% on side and rear windows. Film colors not permitted: red, amber (windshield strip).
Medical exemptions
Oklahoma allows darker tint with a medical exemption. DPS Medical Standards Unit issues a letter on a licensed physician's written attestation; carry it in the vehicle. Rule caps the exemption at 15% VLT, and below 20% may add a daylight-only license restriction.
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; the default Title 47 penalty is a $5-$500 fine and/or up to six months (47 O.S. §17-101(C)).
In practice
The 25% floor is measured through film and glass together and applies to every window behind the windshield on every vehicle type; the only body-type carve-out is windows behind the driver's seat on buses and taxicabs. Pre-1996 models may run 10% behind the driver if outside mirrors on both sides show 200 feet to the rear. Louvers may not cut visibility below 50%. The section was last amended in 2005, so websites announcing 2025 or 2026 changes have no statutory basis.

Common questions about tint in Oklahoma
Is 25% tint legal on front windows in Oklahoma?
Yes. 25% is the darkest Oklahoma allows on front side windows: the glass and film together must let at least 25% of visible light through. Anything darker fails a meter check.
Can I tint my windshield in Oklahoma?
Only a strip above the AS-1 line or within the top 5 inches, whichever is closer to the top; it may not be red or amber. Film below that line is not permitted for ordinary drivers.
Does Oklahoma allow darker tint for medical reasons?
Yes, with documentation. DPS Medical Standards Unit issues a letter on a licensed physician's written attestation; carry it in the vehicle. Rule caps the exemption at 15% VLT, and below 20% may add a daylight-only license restriction.
What happens if my tint is too dark in Oklahoma?
Misdemeanor; the default Title 47 penalty is a $5-$500 fine and/or up to six months (47 O.S. §17-101(C)).
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.
