Oklahoma law requires front and rear side windows to allow at least 25% of light through and reflect no more than 25%, permits tint on the windshield only above the AS-1 line near the top, and that strip cannot be red or amber. These limits come from 47 O.S. § 12-422, and violating them is a misdemeanor.
Oklahoma’s Window Tint Laws: VLT% Limits by Window
Oklahoma regulates window tint through its vehicle equipment code, 47 O.S. § 12-422. The statute measures tint by visible light transmission, or VLT%: the share of light that can pass through the glass and film together. A lower VLT% means a darker tint.
Here is how the limits break down by window:
- Windshield: Non-reflective tint is allowed only on the strip above the manufacturer’s AS-1 line, typically about five inches down from the top of the glass.
- Front side windows: Must allow more than 25% of light through (VLT% above 25) and reflect no more than 25% of light.
- Back side windows and the rear window: Held to that same 25% VLT% floor and 25% reflectivity cap on any car, truck, or SUV from the 1996 model year or later.
Is There Really No Darkness Limit on Back Windows in Oklahoma?
A lot of tint shops and drivers repeat a myth: front windows have a 25% floor, but the back windows can be as dark as you want. That is not correct for a standard vehicle built in 1996 or later. Section 12-422(D)(1) exempts side or back windows from Oklahoma’s tint restrictions only when the film allows at least 25% light transmission and reflects no more than 25%, the identical standard used for the front side windows.
A second, narrower exemption in 12-422(D)(10) does allow a 10% VLT% floor on windows behind the driver, but only on vehicles from before the 1996 model year, and only when the car has outside mirrors on both sides positioned to give the driver a clear 200-foot rearview. Outside that specific, older-vehicle scenario, “any darkness in the back” is not the rule in Oklahoma.
Reflectivity, Color, and the Windshield’s AS-1 Line
Darkness is only part of the standard. Oklahoma also limits how mirror-like a tint looks and what color it can be:
- Reflectivity: No window may carry a tint that reflects more than 25% of light. Mirrored or metallic finishes are not allowed.
- Color: Tint applied above the windshield’s AS-1 line cannot be red or amber.
- Placement: Windshield tint below the AS-1 line, which covers the driver’s normal forward view, is not permitted at all, regardless of color or reflectivity.
Oklahoma doesn’t flatly ban red or amber tint film on every window, but using it on back or side windows still risks confusion with emergency and law enforcement vehicle equipment, which is regulated separately.
Certification and Who Is Responsible for Compliance
Oklahoma does not require tint film manufacturers to pre-certify their products with the state. It does put a duty on whoever sells or installs the tint: state law requires a written, bold-face statement, made part of the sale or installation contract, certifying that the product meets Oklahoma’s reflectivity and light-transmission limits. That same statement has to tell the customer that installing tint on the front driver’s or passenger’s window may be illegal in other states, which is worth knowing if the car will be driven or registered elsewhere.
Oklahoma does not issue a physical compliance sticker for tinted windows. That written seller’s certificate, kept with the sale paperwork, is the main record showing the tint was installed to the legal standard at the time. Day to day, a vehicle owner is the one responsible for making sure the tint still meets the law, including after it is resold or re-tinted. The full vehicle equipment code sits in Title 47 of the Oklahoma Statutes, published by the state legislature.
Medical Exemptions for Darker Window Tint in Oklahoma
Oklahoma allows a medical exemption from the standard tint limits for a driver or regular passenger who needs protection from direct sunlight for a documented medical reason. The exemption is issued by the Commissioner of the Department of Public Safety, part of Oklahoma’s state government. It is not automatic just because a doctor recommends it. The application has to include a written attestation from a physician licensed under 59 O.S. Section 495, and the Commissioner decides whether to issue the exemption for that specific vehicle.
A separate, narrower provision covers non-attached, removable sun shades on a front wing vent or window (the clip-on kind, not film applied to the glass) used only while the vehicle is being driven in daylight. That is a limited accommodation for temporary glare, not a general rule allowing extra-dark permanent tint whenever a car is driven only in daylight hours.
Penalties for Illegal Window Tint in Oklahoma
Violating Oklahoma’s window tint law is a misdemeanor under 47 O.S. § 12-422(I), punishable as provided in 47 O.S. § 17-101. In practice, that can mean:
- A fine, with the exact amount and any court costs set by the court handling the citation.
- An equipment citation or fix-it order requiring the tint to be brought into compliance or removed before the case closes.
- Points added to a driving record for repeated violations, which can affect insurance rates.
- A required court appearance in repeat-offense situations, rather than a simple fine.
An officer can check tint darkness during any traffic stop, including one made for an unrelated reason like speeding. Illegally dark tint is not usually the reason a car gets pulled over in the first place, but it can add a second citation once a stop happens.
How a Tint Violation Can Affect a Car Accident Claim
A window tint citation by itself is a traffic infraction, not a car accident case. But the two can end up connected. If a stop for suspected illegal tint turns up other issues, or an insurance adjuster tries to make an issue of your tint after a crash that wasn’t your fault, the citation does not erase the other driver’s responsibility for causing the collision. Fault for a wreck and fault for an equipment violation are evaluated separately under Oklahoma law.
If you have been issued a window tint ticket around the same time as a crash, how a traffic ticket can factor into your claim is worth understanding before you talk to an adjuster.

Frequently Asked Questions About Oklahoma Window Tint Laws
Do Oklahoma’s tint laws vary by city, like Tulsa or Oklahoma City?
No. The VLT% and reflectivity limits in 47 O.S. § 12-422 apply the same way statewide. Local police departments enforce the same statute rather than setting their own separate tint rules.
Is 5% tint legal in Oklahoma?
No. Often called “limo tint,” 5% VLT% is far below Oklahoma’s 25% floor for both front and back windows on a standard vehicle, and it doesn’t fit the narrow pre-1996 exception either, since that one tops out at 10%. A Department of Public Safety medical exemption is the only route to legally running tint that dark on a specific vehicle.
Is 20% tint legal in Oklahoma?
Not on a typical car, truck, or SUV. Oklahoma’s standard floor is 25% VLT% for front side windows and for back side and rear windows alike. The one exception is a vehicle from before the 1996 model year with adequate outside mirrors, which can go as low as 10% on the windows behind the driver. So 20% would only be legal in that specific, older-vehicle situation.
Do out-of-state vehicles have to follow Oklahoma’s tint law?
Yes, while they’re being driven in Oklahoma. A tint that’s legal in a driver’s home state is not automatically legal here, so carrying documentation of the tint’s specs can help resolve questions during a stop.
Do window tint installers need a special license in Oklahoma?
Oklahoma doesn’t individually license tint installers. What the law requires is a written, bold-face certification, made part of the sale or installation paperwork, stating that the product meets the state’s reflectivity and light-transmission limits.
How much does it cost to have illegal tint removed?
Professional removal typically runs between $50 and $150, depending mainly on the vehicle’s size and how much of it is tinted.
What exactly is the AS-1 line on a windshield?
It’s a manufacturer-marked line, usually about five inches down from the top of the windshield, separating the section where non-reflective tint is allowed from the section where it isn’t.
Can I be cited for illegal tint while the car is parked?
It’s uncommon but possible. Most tint citations happen during a traffic stop made for another reason, since an officer generally needs to see the vehicle in operation or have some other basis for contact.
Are tinted license plate covers legal in Oklahoma?
No. Oklahoma law requires license plates to stay clearly legible, and a tinted or smoked cover that obscures the plate is not allowed.
Can window tint become illegal over time even if it was installed correctly?
Yes. Tint film can fade, bubble, or discolor with age and sun exposure, which can drop its actual light transmission below the legal floor even though it met the standard when installed. A periodic check, especially before a registration renewal, can catch this before it becomes a citation.
