Window Tint Laws in North Carolina: The 35% Rule and What Changed

Last reviewed: October 17, 2026. This article is general information, not legal advice. North Carolina changed how tint is enforced on December 1, 2025; check the current statute and NCDMV guidance before you buy film.

North Carolina's tint numbers have been steady for years, but the way they are enforced changed recently. Inspection stations no longer check tint, and there is a new rule about rolling your window down when an officer walks up. Here is the full picture. For other states, see our window tint laws by state chart.

Short answer: Window tint laws in North Carolina require every window except the windshield to have at least 35% total light transmission and 20% or less reflectance; a meter reading above 32% is conclusively presumed legal. The windshield may be tinted only in the top 5 inches or down to the AS-1 line, whichever is longer. Windows behind the driver of a multipurpose vehicle (including minivans and pickups) are exempt. Since December 1, 2025, tint is no longer checked at safety inspection, but the limits still apply.

How the 35% and 32% figures fit together

The legal standard is 35%. The 32% figure is an enforcement rule: if an approved meter reads more than 32%, the window is "conclusively presumed" to meet the 35% standard. That three-point margin allows for meter error and factory glass. It does not make 32% the limit; a window that reads exactly 32% or less does not get the presumption.

NCDMV puts it this way: "Tinted windows may not measure darker than 32 percent when tested with a North Carolina-approved window-tint meter."

Measure the finished window, film and glass together. A film sold as "35%" will usually read darker once it is on your glass.

The windshield

Under § 20-127(b), "The windshield of the vehicle may be tinted only along the top of the windshield and the tinting may not extend more than five inches below the top of the windshield or below the AS1 line of the windshield, whichever measurement is longer." An untinted clear film that blocks ultraviolet radiation and does not obstruct vision may cover the rest. Section 20-127(c) says the windshield rules apply without exception, so none of the vehicle-type exemptions below unlock a darker windshield.

Who is exempt

Section 20-127(c) lifts the 35% and 20% limits (but not the colour and reflectivity rule in (b)(3)) for:

• Windows behind the driver of a multipurpose vehicle, defined as a passenger vehicle designed to carry 10 or fewer people that is built on a truck chassis or has features for occasional off-road use. The statute says "A minivan and a pickup truck are multipurpose vehicles."
• The rear window of a property-hauling vehicle.
• Excursion passenger vehicles, motor homes, ambulances, limousines and law enforcement vehicles.
• Vehicles registered in another state that meet their home state's rules.
• Vehicles with a medical exception permit.

Commercial vehicles covered by federal motor carrier rules (49 C.F.R. Part 393) follow those rules instead (§ 20-127(b1)).

What changed in December 2025

North Carolina's 2025 transportation law, S.L. 2025-47, changed tint enforcement. According to NCDMV:

• "As of December 1, 2025, window-tint checks are no longer required as part of North Carolina safety inspections."
• The $10 window-tint inspection fee was eliminated.
• During a traffic stop, drivers of vehicles with tinted windows must roll down the window on the side the officer approaches.

That last rule is now § 20-127(g): "The driver of a vehicle with tinted windows shall roll down the driver side window upon the approach of a law enforcement officer. If the officer approaches from the passenger side, the driver shall roll down the passenger window."

So a dark-tinted car can now pass inspection, but it can still be stopped and cited on the road.

Penalties and the 15-day fix

Under § 20-127(d), it is a Class 3 misdemeanor to drive with a window that breaks the tint rules, or to apply tint that breaks them to a vehicle subject to safety inspection in North Carolina. Unless another law says otherwise, the maximum fine for a Class 3 misdemeanor is $200 (§ 15A-1340.23(b)).

North Carolina gives drivers a way out. Under § 20-127(e), it is a defense to a charge of driving with illegal tint that the tint "was removed within 15 days after the charge" and the window now complies. You must give the court, or the prosecutor before trial, a certificate from the Division of Motor Vehicles or the Highway Patrol showing the window meets the rules. Act quickly, because the 15 days start on the date of the charge.

Medical exception permits

Section 20-127(f) lets a person whose medical condition makes them photosensitive to visible light get a permit for darker tint:

1. Apply in writing to the DMV's Drivers Medical Evaluation Program.
2. Have your doctor complete the medical evaluation form provided by the Division.
3. The permit is valid for five years unless the program sets a shorter term; renewal needs a new medical certification.
4. A person may hold no more than four permits at once. Each permit names the vehicle, the windows and the permitted tint level, and must be carried in that vehicle.
5. DMV issues a sticker for the lower left corner of the rear window, placed between the glass and the film. Failing to display it is an infraction with a $200 fine.

Common mistakes in North Carolina

• Treating 32% as the legal limit. The law is 35%; more than 32% on a meter is just the safe harbour.
• Thinking inspection approval means the tint is legal. Stations no longer check it.
• Missing the 15-day window. The repair defense only works if you remove the tint within 15 days and get the certificate.
• Using red, yellow or amber film. Those colours are banned even on exempt windows.
