Kentucky Window Tint Law
Kentucky regulates window tint under KRS 189.110. The law sets specific VLT (Visible Light Transmission) limits depending on your vehicle type and window position. Kentucky also uniquely requires installers to place a permanent vinyl label on every tinted vehicle.

Kentucky VLT Limits at a Glance
VLT (Visible Light Transmission) is the percentage of light that passes through your window film. Lower numbers mean darker tint.
What Does VLT Mean?
VLT stands for Visible Light Transmission — it measures the percentage of visible light that passes through your window and film combined. A 35% VLT window allows 35% of outside light in and blocks 65%.
Kentucky allows a ±3% tolerance on all VLT measurements. This means a 35% VLT window could read anywhere from 32% to 38% and still pass inspection. At Classic Shades, we always aim for the safe side of the tolerance to keep you compliant.

Reflectivity Limits
Kentucky limits the amount of reflectivity (mirror effect) in window tint. Highly reflective or mirrored films can blind other drivers and are restricted.
All Autobahn ceramic films installed by Classic Shades are non-reflective and fall well within Kentucky's reflectivity limits.
Kentucky's Unique Installer Label Requirement
Kentucky is one of the few states that requires the tint installer to affix a non-removable vinyl label on the inside of the driver's (left) door jamb. The label must include the installer's trade name and installer information.
Every Kentucky installation from Classic Shades includes this compliance label at no extra charge. It's one more reason to choose a professional installer who knows the law.
Medical Exemptions
Kentucky allows medical exemptions under KRS 189.110(5), but they are very narrowly applied. To qualify, you must:
- Have a diagnosed photosensitive medical condition
- Obtain a physician certification documenting the condition
- Carry the certification in the vehicle at all times
If you believe you qualify, consult your physician first. Classic Shades can install exempt-level tint once you have proper documentation.
Penalties for Illegal Tint
Under KRS 189.990, Kentucky takes tint violations seriously, with escalating penalties for repeat offenses:
Fine only
Fine + possible jail time
Fine + jail time
What Classic Shades Recommends
With over 37 years of experience and thousands of installations for Kentucky drivers, here's what we recommend:
For Sedans & Coupes
35% VLT on the front side windows with 18% or 20% on the rear side and rear windshield. This keeps you legal while providing solid heat rejection and privacy.
For SUVs & Trucks
35% VLT on the front side windows with 15% or darker on the rear. Kentucky's generous SUV/truck rear limits let you go much darker for maximum privacy and UV protection.
Our Film of Choice
We install Autobahn ceramic film — it blocks up to 99% of UV rays and rejects more heat than dyed films, all while staying within Kentucky's reflectivity limits. Every install comes with a lifetime warranty.
