Kansas window tint laws set a 35% minimum visible light transmission for all windows on passenger vehicles. The law permits tint on the windshield only above the AS-1 line and prohibits reflective mirrored tint. A violation of Kansas window tint laws is a Class C misdemeanor with a total fine of about $96.50. This article explains the legal VLT limits, the AS-1 line rule, the penalty structure, and the commercial vehicle exception. The rules come from Kansas Statutes Annotated Section 8-1749a and the Kansas Highway Patrol.
Visible Light Transmission and Key Terms
Visible light transmission or VLT measures the percentage of light that passes through your window and tint film together. A 35% VLT means the window allows 35% of visible light through and blocks the other 65%. The law requires 35% VLT as the absolute minimum for every window on a Kansas passenger vehicle. Higher VLT numbers mean lighter tint while lower numbers mean darker tint that is illegal. Many people confuse film VLT with the total combined VLT that includes the factory glass.
Factory window glass already reduces light transmission before you add any aftermarket film. A film labeled 35% VLT may produce a combined VLT of 30% or lower when applied over factory glass. The legal standard in Kansas applies to the combined VLT not just the film rating. You need a tint meter to accurately measure the total light transmission of your installed window. The Kansas Highway Patrol uses these meters during traffic stops to test compliance.
The AS-1 line is a marking on the windshield typically located about five inches from the top edge. Windshield tint cannot extend below this AS-1 line on the driver side. The tint above the AS-1 line must be non reflective and cannot be red yellow or amber. The AS-1 line marking is often visible as a dark band or etched line in the glass. You can check your windshield to locate this line before applying any tint.
What the Kansas Window Tint Law Says
Kansas Statutes Annotated Section 8-1749a establishes the legal requirements for window tint on vehicles registered in Kansas. The statute requires 35% minimum VLT for front side windows rear side windows and the rear window. Windshield tint is permitted only above the AS-1 line with non reflective material. Reflective mirrored tint is prohibited on any window of a passenger vehicle. The statute also bans red yellow and amber tint colors on all windows.
The law enforcement exception allows police vehicles to have darker tint than the 35% standard. The statute explicitly states that Kansas does not offer medical exemptions for darker window tint. A doctor note does not permit you to install tint below the 35% minimum in Kansas. The law requires the AS-1 line measurement from the top of the windshield for passenger cars. Kansas Highway Patrol guidance confirms these requirements on their consumer equipment page.
The Kansas statute also addresses sun screening devices and defines them as any material applied to glass to reduce light transmission. The law treats window film as a sun screening device subject to the VLT requirements. The statute includes provisions for the rear window mirror requirement when tint is applied. If the rear window has tint below 35% VLT the vehicle must have dual side mirrors. This requirement ensures driver visibility even with a tinted rear window.
Who the Kansas Window Tint Law Applies To
The Kansas window tint law applies to all passenger vehicles registered in the state of Kansas. This includes cars sedans SUVs vans and pickup trucks operating on Kansas roads. The 35% VLT rule applies uniformly across all these vehicle types without exception. SUVs do not have different tint rules for rear windows in Kansas. Passenger vehicles with aftermarket tint must comply with the 35% minimum on every window.
Commercial vehicles have a different standard that comes from federal regulations. Federal Motor Carrier Safety Regulation 49 CFR Section 393.60 requires 70% VLT for front side windows on commercial vehicles. This federal standard applies to the windshield and front side windows of commercial trucks and buses. The 70% requirement is stricter than the state 35% rule for these specific windows. Commercial vehicle operators must meet the federal standard on those windows regardless of Kansas law.
The Kansas Highway Patrol enforces the state law on all public roads within Kansas. Out of state drivers with tint below 35% VLT may receive citations in Kansas. The law does not apply to vehicles that are not registered in Kansas. Enforcement typically occurs during traffic stops for other violations. Kansas Highway Patrol officers are trained to use tint meters during roadside inspections.
Requirements and Elements of Legal Tint
Non reflective tint is the only type allowed under Kansas Statutes Annotated Section 8-1749a. Reflective or mirrored tint creates a metallic appearance that is prohibited on any window. The non reflective requirement applies to all windows including the rear window of SUVs. You can use tint that reduces glare without creating a mirror like appearance. The statute does not specify a maximum reflectance percentage because reflective tint is entirely banned.
Color restrictions in Kansas prohibit red yellow and amber tint shades. These colors are banned because they can mimic emergency vehicle lights. The law allows neutral gray smoke black and other non red non yellow non amber colors. Tint with a slight green or blue hue is generally acceptable under the statute. The Kansas Highway Patrol can issue citations for tint colors that appear red yellow or amber.
The dual side mirror requirement applies when you tint your rear window. Kansas law requires both a driver side and passenger side outside mirror if the rear window has tint. These mirrors allow you to see behind your vehicle without relying on the rear window. The mirrors must provide a clear view of the road behind you. Many vehicles already have dual side mirrors as standard equipment.
Penalties for Illegal Window Tint in Kansas
A violation of Kansas window tint laws is a Class C misdemeanor under state law. Class C misdemeanors in Kansas carry a potential jail term of up to one month. The total fine for an illegal tint violation is approximately $96.50 including court costs. This amount includes the base fine and mandatory court fees added to the citation. The fine is not just a fix it ticket that disappears after removal.
Law enforcement officers can issue citations for any tint that measures below 35% VLT. The officer tests the tint using a hand held light transmission meter. If the tint fails the meter test the officer can write a ticket on the spot. The ticket requires you to pay the fine or appear in court. A citation for illegal tint appears on your driving record as a misdemeanor charge.
The court costs and administrative fees raise the total penalty above the base fine amount. You must pay the full $96.50 total when you receive a ticket. The court may also order you to remove the illegal tint from your vehicle. You may face additional charges if you fail to remove the tint after a citation. Kansas Highway Patrol data from 2023 shows hundreds of window tint citations issued annually.
The Class C misdemeanor classification means a conviction becomes part of your criminal record. A misdemeanor record can affect employment background checks and insurance rates. The court does not dismiss the charge simply because you remove the tint. You must pay the fine and accept the misdemeanor conviction on your record. The penalty is more serious than a simple equipment violation in many other states.
Exceptions and Limitations in Kansas Tint Law
Law enforcement vehicles have a full exemption from the 35% VLT requirement under Kansas law. Police cars can use darker tint for officer safety and operational needs. The exemption applies only to official law enforcement vehicles and not to private vehicles. Fire department and emergency service vehicles may also qualify for exemptions. Private vehicles cannot claim this exception for any reason.
Kansas does not allow medical exemptions for darker window tint under any circumstance. Some states offer medical waivers for individuals with light sensitivity conditions. Kansas law explicitly does not provide this medical exception in the statute. A physician statement does not authorize darker tint below the 35% minimum. Residents with medical conditions must still comply with the standard 35% VLT requirement.
Clear colorless UV blocking film is allowed with a physician statement for medical purposes. This film does not reduce VLT below the legal minimum and is not considered tint. The UV film protects against harmful rays without darkening the window. You do not need an exemption to use clear UV film on your windows. The film must remain transparent and not reduce light transmission below 35% VLT.
Variation from Neighboring State Rules
Kansas tint laws differ from some of the neighboring states you might drive through. Missouri allows 35% VLT for front side windows but permits any darkness on rear windows. Oklahoma has a 25% VLT limit for front side windows which is darker than Kansas. Nebraska allows 35% VLT for all windows similar to Kansas law. Colorado allows 27% VLT for front side windows and any darkness for rear windows.
Drivers who cross state lines should be aware that each state enforces its own tint laws. Kansas law applies to vehicles registered in Kansas regardless of where you drive. Drivers from other states must follow Kansas law while operating in Kansas. A vehicle with out of state plates can still receive a citation for illegal tint in Kansas. The enforcement officer will check your tint during a traffic stop regardless of your plates.
The legal variation between states creates confusion for drivers who travel frequently. Some drivers install tint that complies with the strictest state in their travel area. Others choose to remove tint before crossing into more restrictive states. The safe approach is to verify each state law before traveling. Kansas law requires the full 35% VLT standard for all windows on Kansas vehicles.
Common Misconceptions about Kansas Tint
Many drivers believe that a medical exemption allows darker tint in Kansas. This belief is false because Kansas Statutes Annotated Section 8-1749a explicitly denies medical exemptions. A doctor letter does not give you permission to install illegal tint. The law does not recognize light sensitivity or skin conditions as valid reasons for darker tint. You cannot avoid a ticket by presenting medical documentation to a Kansas officer.
Another common misconception is that SUVs can have darker tint on rear windows. The Kansas law applies the 35% VLT minimum to all vehicle types equally. SUVs vans and trucks have the same rear window tint requirements as sedans. The vehicle class does not change the legal standard in Kansas. Some online sources incorrectly state that SUVs have different rules but the statute says otherwise.
Drivers also believe that 35% VLT film is always legal on any vehicle. This is false because the VLT measurement includes both the factory glass and the aftermarket film. Factory glass typically reduces light transmission by several percentage points. A film labeled 35% may create a combined VLT of 28% or less. You should test the combined VLT to confirm compliance with the legal standard.
How to Check Your Window Tint Compliance
You can check your window tint by using a hand held light transmission meter. These meters measure the actual VLT of your window and film combination. You can buy a meter online or visit a tint shop for a test. The meter reading must show 35% VLT or higher for every window. A reading below 35% means your tint is illegal in Kansas.
The Kansas Highway Patrol recommends checking your tint before any traffic stop. You can identify potential problems by looking at your tint from outside the vehicle. Tint that appears very dark or reflective is likely to fail a meter test. A tint that obscures the view into the vehicle may draw officer attention. You can avoid a ticket by removing any tint that looks too dark.
You can also check with a professional tint installer for a compliance test. The installer will use a calibrated meter to measure every window on your vehicle. The installer can advise whether your tint meets the Kansas legal standard. If your tint fails the test the installer can remove the illegal film. Removal costs less than the $96.50 fine and misdemeanor record.
