Short answer: North Carolina law generally requires at least 35% total light transmission on regulated windows. A reading above 32% on an approved meter is conclusively presumed compliant. Windshield tint is generally limited to the top five inches or the AS-1 line, whichever measurement is longer. The exact vehicle, window and any issued medical permit matter.
Important: this page provides general information, not legal advice. Laws, regulations and official interpretations can change. Before relying on any summary, read the current North Carolina General Statute § 20-127 and NCDMV inspection guidance.
Did North Carolina make dark tint legal in 2025?
No. NCDMV says window-tint checks and the additional $10 tint fee were removed from annual safety inspections effective December 1, 2025. The same NCDMV page says vehicles with after-factory tint must still comply with G.S. 20-127.
In other words, “not checked during the annual inspection” does not mean “any darkness is legal.” The underlying restrictions remain enforceable.
What darkness does the statute allow?
For windows covered by the general rule, § 20-127(b)(1) requires total light transmission of at least 35%. It also says a window measuring more than 32% on a meter approved by the Commissioner is conclusively presumed to meet that restriction.
Total light transmission is the finished reading. It includes the vehicle glass and the installed film together. Factory glass can affect the result, so the percentage printed on a film sample or box does not guarantee the same final meter reading on every vehicle.
| Rule | What the statute says | Practical meaning |
|---|---|---|
| Light transmission | At least 35% on regulated windows | Glass and film combine in the final reading. |
| Meter presumption | More than 32% on an approved meter is conclusively presumed compliant | A labeled “35% film” is not automatically a 35% finished window. |
| Light reflectance | 20% or less | Highly reflective results may not comply. |
| Film appearance | Nonreflective; not red, yellow or amber | Color and reflectivity rules apply in addition to darkness. |
| Windshield tint | Top five inches or the AS-1 line, whichever measurement is longer | The permitted visor area depends on the windshield markings and measurement. |
What is allowed on the windshield?
The statute generally permits tint only along the top of the windshield. It may not extend more than five inches below the top or below the AS-1 line, whichever measurement is longer.
A separate provision allows an untinted clear film that does not obstruct vision and reduces or eliminates ultraviolet radiation. That language does not describe a dark full-windshield film.
Which vehicles or windows have exceptions?
Section 20-127(c) lists exceptions to the 35% light-transmission and 20% reflectance provisions for specific windows or vehicles. Examples include windows behind the driver on a qualifying multipurpose vehicle, certain motor-home, ambulance, limousine and law-enforcement windows, some property-hauling rear windows, vehicles registered in another state that comply with that state, and vehicles covered by an issued medical exception permit.
A multipurpose vehicle is a defined category; the statute says a minivan and pickup truck are multipurpose vehicles. The exact vehicle classification and window position still matter. The windshield restrictions apply without those general exceptions.
How does the medical exception work?
A person with a qualifying condition that causes photosensitivity to visible light may apply through the Drivers Medical Evaluation Program. A doctor must complete the required medical evaluation. A permit can be valid for up to five years, identifies the vehicle, windows and permitted tint levels, and must be carried in the vehicle.
The Division also issues a sticker that must be installed as directed. A medical need does not create an automatic exception without the permit process.
Who can be responsible for a violation?
Under § 20-127(d), a person who applies tint to a window of a vehicle subject to North Carolina safety inspection commits a Class 3 misdemeanor if the resulting window violates the statute. A person who drives a noncompliant vehicle on a highway or public vehicular area also commits a Class 3 misdemeanor.
The statute therefore addresses both application and operation. An installer should not imply that legal responsibility can simply be transferred to the customer, and a driver should not assume that a completed installation guarantees compliance.
What is the 15-day removal defense?
Section 20-127(e) provides a defense to a charge of driving with an unlawfully tinted window when the tint is removed within 15 days after the charge and the window then complies. To use that defense, the person charged must provide the court—or submit to the prosecutor before trial—a certificate from the Division of Motor Vehicles or Highway Patrol showing compliance.
This is a statutory defense with stated proof requirements, not a guarantee that every charge will disappear automatically. Anyone facing a citation should rely on the current statute and qualified legal advice.
What must a driver do during a traffic stop?
Section 20-127(g) requires the driver of a vehicle with tinted windows to roll down the driver-side window when an officer approaches from that side. If the officer approaches from the passenger side, the driver must roll down the passenger-side window.
Choose film without guessing
- Start with the vehicle year, make, model and body style.
- Identify factory privacy glass and any existing aftermarket film.
- Choose the performance goal: heat control, glare, UV filtering, privacy or appearance.
- Remember that the final meter reading includes the glass and film together.
- Check the current statute and NCDMV guidance before making a legal decision.
- Carry the required documentation for any issued medical exception.
