North Carolina window tint law
Updated November 6, 2026 · 5 min read
Short answer
In North Carolina, tinted side and rear windows must let in at least 35% of light, with a meter reading above 32% presumed legal. Reflectance must be 20% or less, and red, yellow and amber tint are not allowed. On SUVs, pickups and minivans, windows behind the driver are exempt from the darkness limit.
The main rules
- Side and rear windows: at least 35% total light transmission. A reading above 32% on a state-approved meter is presumed to comply.
- Reflectance: 20% or less. Mirror-like film is not allowed.
- Colors: no red, yellow or amber tint.
- Windshield: tint only along the top, no lower than 5 inches from the top or the AS1 line, whichever is longer. Clear UV film is allowed.
Who is exempt from the darkness limit
These exemptions never cover the windshield.
- Windows behind the driver on multipurpose vehicles, which includes most SUVs, minivans and pickup trucks
- The rear window of a property-hauling vehicle
- Limousines, motor homes, ambulances and some other special vehicles
- Cars registered in another state that meet that state’s rules
- Drivers with a valid NC medical exception permit
Medical exceptions
If a medical condition makes you sensitive to light, you can apply in writing to the NC DMV Drivers Medical Evaluation Program, with a form completed by your doctor. Permits are usually valid for 5 years. You must keep the permit in the car and display the sticker on the lower left corner of the rear window.
Penalties
Driving with illegal tint, or installing it on a car that needs an NC safety inspection, is a Class 3 misdemeanor. It is a defense if you remove the tint within 15 days and get a DMV or Highway Patrol certificate showing the window now complies. Tint is also checked at your annual safety inspection.
What this means at the shop
A reputable Charlotte installer will tell you which film shade keeps you legal on your vehicle. Film shades are labeled by light transmission, but the reading is taken through the glass and film together, and factory glass already blocks some light. That’s why many shops use 35% or lighter film on sedans.
Common questions
Is 20% tint legal in NC?
Not on the front side windows of a passenger car. On an SUV, pickup or minivan, it’s allowed on windows behind the driver.
Can I tint my whole windshield?
No. Only the top 5 inches or down to the AS1 line. Clear, non-tinted UV film is allowed.
This is a plain-language summary, not legal advice. Check the statute or ask NC DMV if you’re unsure about your vehicle.
