Oklahoma window tint laws require front side windows to allow more than 25% VLT under Oklahoma Statutes Title 47 Section 12-422. Back side and rear windows follow the same 25% VLT floor on standard passenger cars. Multi purpose vehicles such as SUVs vans and trucks receive broader exemptions on rear glass under the same statute. This guide covers windshield rules reflectivity limits penalties and the medical exemption process. The primary source is Oklahoma Statutes Title 47 Section 12-422 enforced through the Oklahoma Department of Public Safety.
Key Terms in Oklahoma Tint Law
Visible Light Transmission describes the percentage of light that passes through the combined tint film and glass. A higher VLT percentage means a clearer window and a lower VLT percentage means a darker window. Oklahoma Statutes Title 47 Section 12-422 uses light transmission percentages to set the legal floor for each window type. Luminous reflectance is a separate measurement describing how much light the tint bounces back outward rather than letting it pass through, and Oklahoma caps this separately from VLT.
The AS-1 Line Explained
The AS-1 line is a factory mark near the top of the windshield showing where manufacturers permit certain treatments to the glass. Oklahoma Statutes Title 47 Section 12-422 allows non reflective material on the windshield only above this line or within the top five inches of the windshield, whichever point sits closer to the top. Material placed below that line or lower than five inches down violates the statute regardless of how light the tint appears to be.
What Oklahoma Statutes Title 47 Section 12-422 Requires
The statute makes it unlawful to sell install or operate a vehicle with any object or material placed on the windshield or side or rear windows that obstructs or reduces the driver’s clear view. It also bars any transparent material that alters window color or reduces light transmittance except where the statute lists a specific exception. These rules apply uniformly across Oklahoma regardless of county or city, since window tint regulation in this state is set at the state level rather than through local ordinance.
Front Side Window Rules
Front side windows on a standard passenger vehicle must allow more than 25% VLT under Oklahoma Statutes Title 47 Section 12-422 subsection D. This means the film and glass combined cannot block enough light to drop transmission at or below the 25% threshold. Front side windows also carry a reflectivity limit alongside the VLT rule, since a compliant VLT percentage does not automatically make a highly reflective tint legal on its own.
Back Side and Rear Window Rules
Back side windows and the rear window on a standard passenger car must also allow more than 25% VLT under the same subsection of Oklahoma Statutes Title 47 Section 12-422. The statute separately exempts side windows to the rear of the driver and back windows meeting at least 10% VLT and at most 25% reflectance for vehicles manufactured before 1996 model years, provided the vehicle carries dual outside mirrors. Multi purpose vehicles receive additional statutory flexibility on rear glass compared to standard sedans.
Reflectivity and Color Restrictions
Oklahoma Statutes Title 47 Section 12-422 defines luminous reflectance as the ratio of total light reflected outward by the tint compared to the total light striking it, expressed as a percentage. The statute restricts transparent material on the windshield to non reflective material only, and any material placed there cannot be red or amber in color. These color and reflectivity limits apply in addition to the VLT thresholds, so a tint can fail the law on reflectivity or color even while meeting the VLT percentage.
Who Oklahoma Tint Law Applies To
Oklahoma Statutes Title 47 Section 12-422 applies to any person who sells installs or operates a motor vehicle within the state, covering both the installer and the vehicle owner or driver. The statute lists fifteen specific situations excluded from the general restriction, ranging from rearview mirrors to certain factory equipment to vehicles not subject to Oklahoma registration. Understanding which exemption category a vehicle or situation falls under is central to knowing whether a given tint configuration is lawful.
Sedans Compared to Multi Purpose Vehicles
Standard passenger cars must meet the 25% VLT floor on front side back side and rear windows without the broader rear window flexibility given to larger vehicle classes. Multi purpose vehicles including SUVs vans and trucks receive different statutory treatment on rear windows under the same section, reflecting the practical reality that these vehicle types often include cargo or passenger areas separated from the driver. The windshield rule and the front side window rule remain identical across both vehicle classes.
Statutory Exceptions Beyond Vehicle Class
Oklahoma Statutes Title 47 Section 12-422 excludes rearview mirrors adjustable non transparent sun visors mounted forward of the side windows and certain signs or stickers displayed in a defined lower corner area of the windshield. The statute also excludes rear window wiper motors rear window defrosters and rear truck lid handles or hinges from the general restriction. Buses taxicabs vehicles not subject to Oklahoma registration implements of husbandry and law enforcement vehicles owned by the state or a political subdivision are separately excluded.
Penalties for Violating Oklahoma Tint Law
A person convicted of violating Oklahoma Statutes Title 47 Section 12-422 is guilty of a misdemeanor punished under Oklahoma Statutes Title 47 Section 17-101. That section sets a fine of not less than $5 nor more than $500 or imprisonment for not more than six months or both the fine and imprisonment together. The statute does not set one fixed penalty amount, so the specific fine imposed within that range depends on the circumstances of the individual case and the court handling it.
What the Penalty Range Means in Practice
Because Section 17-101 provides a range rather than a flat fine, a person cited for illegal tint should expect a monetary penalty somewhere between $5 and $500 rather than assuming a single standard amount applies statewide. The statute also allows imprisonment up to six months as an alternative or additional penalty, though window tint violations are generally treated as equipment violations rather than moving violations. Courts retain discretion in setting the penalty within the statutory range for each conviction.
Medical Exemptions From Oklahoma Tint Law
Oklahoma Statutes Title 47 Section 12-422 subsection H allows the Commissioner of Public Safety to issue an exemption to a person who must be shielded from direct sunlight for medical reasons. The application requires written attestation from a physician licensed under Oklahoma Statutes Title 59 Section 495 confirming the medical necessity. The Oklahoma DPS tinted window exemption application is the official form used to request this exemption from the Department of Public Safety Medical Standards Unit.
How the Medical Exemption Process Works
The official application requires the licensed healthcare provider to state whether the patient’s condition affects safe vehicle operation and whether the condition is permanent or temporary. Oklahoma administrative guidance referenced on this form permits tinting up to but not exceeding 15% for an approved medical exemption. An exemption granted below 20% may also carry a daylight driving only restriction along with any other restriction the state determines appropriate for that driver’s license.
Driver License Review Tied to the Exemption
Submitting the medical exemption application means the applicant’s ability to operate a motor vehicle may be reviewed under Oklahoma Statutes Title 47 Section 6-119, following standards set by the Driver License Medical Advisory Committee created under Oklahoma Statutes Title 47 Section 6-118. This review process exists separately from the tint exemption itself, since the state uses the same medical information to evaluate overall driving fitness. Applicants submit the completed form by mail or email directly to the Medical Standards Unit.
Common Misconceptions About Oklahoma Tint Law
Many drivers assume factory tinted rear glass on an SUV or van automatically satisfies every requirement of Oklahoma Statutes Title 47 Section 12-422, but the reflectivity and color restrictions still apply regardless of vehicle class. Another common misunderstanding treats the VLT percentage as the only relevant figure, when the statute separately restricts luminous reflectance and prohibits red or amber coloring on windshield material. A third misconception assumes a single fixed ticket amount exists statewide, when Oklahoma Statutes Title 47 Section 17-101 actually sets a range between $5 and $500.
Laws and enforcement may change, so drivers should verify current requirements with official Oklahoma sources before installing or modifying window tint. The statute governing tint darkness reflectivity and color has remained in its current form since an amendment effective September 1, 2005, but administrative guidance tied to medical exemptions can be updated separately by state agencies. The Oklahoma Statutes Section 12-422 window tint law and the Oklahoma Statutes Section 17-101 misdemeanor penalties remain the two statutes governing tint darkness and its penalty in this state.
