Kentucky window tint laws set the legal VLT limit for front side windows at 35% minimum light transmission. The rear side window limit for sedans is 18% VLT minimum. SUVs and vans can use any darkness on rear windows. This guide covers windshield rules penalties and medical exemptions. The Kentucky Revised Statutes Section 189.110 provides the legal authority for these limits.
Windshield Tint Rules
Kentucky law now allows windshield tinting with a minimum 70% VLT. Senate Bill 46 passed in 2024 changed this rule. The law took effect in July 2024. Windshields previously could not have any aftermarket tint below the AS-1 line. The AS-1 line is a factory mark about 5 inches from the top of the windshield.
Tint above the AS-1 line is still permitted as before. Tint below the AS-1 line must now allow 70% of light through. This rule applies to all passenger vehicles in Kentucky. Commercial vehicles may have different requirements. The law does not allow any tint that reduces visibility below the AS-1 line.
Enforcement officers use light meters to test windshield VLT. The meter measures the combined light transmission of the glass and the tint film. A 70% reading meets the legal standard. Readings below 70% violate the statute. Officers may allow a 3% tolerance on meter readings.
Front Side Window Limits
Front side windows must allow at least 35% VLT. This rule applies to the driver and passenger windows beside the front seats. The 35% limit is the same for all vehicle types. Sedans and SUVs and trucks must all follow this rule. Tint films with lower VLT percentages violate the law.
The 35% VLT measurement includes the factory window glass. Some factory glass already reduces light transmission by a few percent. A tint film rated at 38% may read 35% when installed. A film rated at 35% may read 32% or 33% on the meter. The 3% enforcement tolerance accounts for these variations.
Reflectivity on front side windows is limited to 25%. The tint film cannot have a mirrored or metallic appearance above this level. High reflectivity can cause glare for other drivers. The law prohibits reflective tint that obscures the vehicle interior. Enforcement officers check reflectivity during traffic stops.
Rear Side Window Rules for Sedans
Sedans and passenger cars have a rear side window limit of 18% VLT. This applies to windows behind the front seats on both sides. The 18% limit is less restrictive than the front window 35% rule. Sedan drivers can use darker tint on rear passenger windows. The rear window itself also falls under this 18% limit for sedans.
The 18% VLT means the tint allows 18% of visible light through. A 20% tint film may read 18% when installed on factory glass. The 3% enforcement tolerance applies to rear side windows as well. Readings below 18% violate the statute. Officers issue citations for readings under the minimum.
Sedan rear windows must have dual side mirrors if the rear window is tinted. The driver must see behind the vehicle through the side mirrors. Dark rear tint can reduce rear visibility. The side mirrors provide the required visibility. This rule applies to all sedans with rear window tint.
SUV and Van Rear Window Rules
SUVs vans and trucks can use any darkness on rear windows. The law does not set a VLT minimum for these vehicles. Rear side windows and the back window can be completely opaque. This rule recognizes the different design of larger vehicles. Many SUVs and vans have factory privacy glass with low VLT.
The front side window 35% limit still applies to SUVs. The windshield 70% rule also applies to SUVs. Only the rear window areas have no VLT limit. Dual side mirrors are required on SUVs with dark rear tint. The driver must maintain visibility through the side mirrors at all times.
Commercial trucks and buses follow the same rear window rules. The law exempts these vehicles from rear VLT limits. Vehicle manufacturers sometimes install dark glass from the factory. Factory installed tint must meet federal safety standards. Aftermarket tint on rear windows of SUVs has no additional state restriction.
Color and Reflectivity Restrictions
Kentucky law prohibits red yellow amber and blue tint colors. These colors resemble emergency vehicle lights. Tint with these colors is illegal on any window of a passenger vehicle. The law also restricts any tint that imitates law enforcement markings. Violators face the same penalties as VLT violations.
Reflectivity on front side windows is capped at 25%. The reflective coating cannot exceed this percentage. Reflective tint can cause dangerous glare in sunlight. Drivers behind a reflective vehicle may experience reduced visibility. Enforcement officers check reflectivity during vehicle stops.
Metallic and mirrored tint films must stay within the reflectivity limit. Some high performance films reflect more than 25% of light. These films are illegal on Kentucky front side windows. Rear windows have no explicit reflectivity limit in the statute. However extreme reflectivity could still draw law enforcement attention.
Medical Exemption Process
Kentucky law allows a medical exemption for darker window tint. Kentucky Revised Statutes Section 189.110 subsection 5 provides this authority. A licensed physician must certify a photosensitive medical condition. Qualifying conditions include lupus albinism and xeroderma pigmentosum. Other light sensitive skin or eye conditions may also qualify.
The physician must provide a written certification for the exemption. The certification must state the specific medical condition. The patient must carry the certification in the vehicle at all times. Law enforcement may request to see the certification during a traffic stop. The exemption allows tint darker than the legal VLT limits.
Patients must renew the medical exemption certification periodically. The physician determines the renewal timeline based on the condition. The exemption applies only to the vehicle driven by the patient. Other drivers of the same vehicle cannot rely on the exemption. The exemption does not waive the windshield tint rules.
Compliance Sticker Requirement
Kentucky law requires a compliance sticker on every tinted vehicle. The sticker certifies that the tint film meets state standards. The tint installer must place the sticker on the driver side door jamb. The sticker cannot be removed or obscured. Installation shops receive the stickers from the tint film manufacturer.
The compliance sticker shows the tint film VLT rating. Officers can check the sticker during a traffic stop. The sticker helps enforcement verify legal tint quickly. Vehicles without a compliance sticker may receive a citation. The law requires the sticker for all professionally installed tint.
Do it yourself tint installation also requires a compliance sticker. Drivers must obtain a sticker for self installed tint. Tint film manufacturers provide stickers with certified film products. The sticker must match the actual installed film. Using a sticker with the wrong VLT rating violates the law.
Penalties for Violation
Window tint violations in Kentucky are Class B misdemeanors. A first offense typically results in a fix it ticket. The driver must remove the illegal tint and provide proof. The ticket is dismissed upon compliance within the deadline. The fine for a first offense ranges from $20 to $100.
Repeat offenses carry higher fines and potential jail time. A second offense can result in fines up to $250. A third offense can result in fines up to $500. Misdemeanor convictions appear on a driving record. Jail time is possible for multiple repeat offenses.
The total cost of a tint violation includes more than the fine. Court costs typically add $50 to $100 to the penalty. Removal of illegal tint costs between $50 and $150. Reinstalling legal tint costs between $100 and $300. The total real cost can exceed $500 for a single violation.
Out of state drivers receive citations under the same law. Kentucky law applies to all vehicles on Kentucky roads. Out of state drivers cannot claim their home state laws apply. Kentucky officers can stop out of state vehicles for tint violations. The penalties apply equally to residents and non residents.
Enforcement and Inspection
Kentucky State Police and local law enforcement enforce tint laws. Officers can stop a vehicle based solely on suspected tint violation. Light meters are used to measure VLT during traffic stops. The meter provides a numerical reading of light transmission. Readings below the legal limit result in a citation.
The 3% enforcement tolerance applies to all VLT measurements. Officers generally do not cite for readings within 3% of the limit. A 32% reading on a front side window may not receive a citation. The tolerance gives drivers a small margin for variance. The tolerance is not a legal right but an enforcement practice.
Regular vehicle safety inspections may include tint checks. Kentucky does not have a statewide annual safety inspection. However some local jurisdictions conduct inspections. County clerks may check tint during vehicle registration. Law enforcement can also check tint during roadside safety checks.
Comparison of Vehicle Types
Sedans and SUVs have different rear window VLT rules. Sedans rear side windows require 18% VLT minimum. SUVs rear side windows have no VLT minimum. This distinction confuses many Kentucky drivers. The front side window 35% rule applies to both vehicle types.
The rear window of a sedan requires 18% VLT minimum. The rear window of an SUV has no VLT minimum. The windshield 70% VLT rule applies to all vehicles. The AS-1 line tint rule also applies to all vehicles. The reflectivity limit of 25% applies to front side windows on all vehicles.
Manufacturer installed glass already has some light reduction. Factory glass typically transmits 70% to 80% of visible light. A 35% film on factory glass may read 28% VLT. This means a 35% film can be illegal on many vehicles. Drivers should verify the combined VLT with a light meter.
Law Updates and Changes
Senate Bill 46 changed Kentucky window tint law in 2024. The bill allowed windshield tint with 70% VLT minimum. The previous law prohibited any aftermarket windshield tint. The bill took effect in July 2024. This change brought Kentucky in line with many other states.
The law did not change other VLT limits. Front side windows remain at 35% VLT minimum. Sedan rear windows remain at 18% VLT minimum. SUV rear windows remain with no VLT limit. The reflectivity and color restrictions also stayed the same.
Drivers should verify current law before installing new tint. The Kentucky General Assembly can amend the law at any time. Check the Kentucky Revised Statutes Section 189.110 for updates. The Kentucky State Police website also provides enforcement guidance. Consult the Kentucky Legislature site at Kentucky Legislature for the official text of KRS 189.110.
Common Misconceptions
Many drivers believe lower VLT numbers mean lighter tint. This is incorrect. Lower VLT percentages allow less light through the window. A 5% tint is extremely dark. A 50% tint is fairly light.
Some sources incorrectly state that Kentucky has no medical exemption. This is false. Kentucky law does allow medical exemptions with physician certification. The exemption process is detailed in the statute. Drivers with qualifying conditions can apply for the exemption.
Some drivers think SUVs must follow the same rear window rules as sedans. This is also false. SUVs can have any darkness on rear windows. Sedans must maintain 18% VLT on rear windows. The vehicle type determines the applicable rear window rule.
Additional Exemptions
Police and emergency vehicles may use darker tint. Law enforcement vehicles have different VLT standards. Government officials may also qualify for exemptions. The statute specifically exempts these vehicles from certain limits. Emergency vehicles need privacy and security for operations.
Hearse vehicles have a rear window tint exemption. Hearses often have completely opaque rear windows. The law recognizes the specialized use of these vehicles. Commercial vehicles used for transportation have some flexibility. The general public does not have these exemptions.
Military vehicles operated on Kentucky roads may also have exemptions. Active duty military members may have vehicles registered in other states. Out of state military vehicles must follow Kentucky law on Kentucky roads. The exemptions are narrowly defined in the statute. Standard passenger vehicles do not qualify for these special exemptions.
Historical Context
Kentucky first enacted window tint laws to improve traffic safety. Dark tint reduces driver visibility in low light conditions. Officers could not see inside vehicles during traffic stops. The original law set conservative VLT limits. Subsequent amendments have adjusted these limits over time.
The 2024 amendment was the most significant change. The windshield tint ban was a long criticized restriction. Proponents argued windshield tint reduces glare and heat. Opponents cited safety concerns about reduced visibility. The General Assembly balanced these interests in SB 46.
Future amendments may adjust VLT limits further. The law could become more permissive as tint technology improves. Safety research continues to inform legislative decisions. Drivers should stay informed about pending legislation. The Kentucky General Assembly website provides bill tracking for proposed laws.
Practical Tips for Drivers
Check the combined VLT of factory glass and tint film. The factory glass already reduces light by 5% to 20%. A film rated at 35% may not be legal. Test the final VLT with a light meter before installation. This prevents costly removal and retinting later.
Use a professional installer who provides a compliance sticker. The sticker certifies the tint meets state standards. Installation shops have experience with legal VLT limits. They can recommend films that stay within the law. Professional installation also ensures proper application.
Keep the medical exemption certification in the vehicle. The certification is required during traffic stops. Present it to the officer if stopped. The exemption does not prevent a ticket if the officer questions its validity. Follow up with the physician if any issues arise.
Consult a licensed attorney if facing a tint violation. An attorney can explain legal options and defenses. The fix it ticket process is straightforward for minor violations. Repeat offenses may require legal representation. The attorney can help navigate the court process and penalties.
Driving with Tint
Tinted windows reduce glare and heat inside the vehicle. This makes driving more comfortable in sunny conditions. Darker tint also provides privacy for the driver and passengers. However dark tint reduces visibility at night. Drivers should consider the trade off before choosing a tint darkness.
Kentucky law balances privacy with safety. The VLT limits ensure adequate driver visibility. The limits allow officers to see inside the vehicle during stops. The restrictions reduce the risk of accidents caused by poor visibility. The law reflects a compromise between competing interests.
Out of state drivers should research Kentucky law before entering the state. A vehicle with legal tint in another state may be illegal in Kentucky. Officers enforce Kentucky law against all vehicles on Kentucky roads. Drivers can receive a citation for tint that was legal elsewhere. Kentucky law does not provide an exception for out of state registration.
If you are considering tinting your vehicle windows, first check the current Kansas window tint laws. The rules are updated periodically by the state legislature. You can verify your state tint requirements and compare with other state limits on our Kentucky traffic laws overview page.
