North Carolina law requires tinted vehicle windows to let in at least 35% of visible light. A window measuring above 32% on an approved meter is presumed to meet that standard.
As of December 1, 2025, window tint is no longer checked during the annual state safety inspection. The tint limits in N.C. General Statute 20-127 remain in force, and officers can still measure your windows during a traffic stop.
Legal tint percentages for North Carolina vehicles
The measurement that matters is visible light transmission, or VLT. It’s the percentage of outside light that passes through the glass and the film together.
A 35% VLT window lets 35% of available light through. Lower numbers mean darker glass.
N.C. General Statute 20-127 sets the standard at 35% VLT for tinted windows. The same statute builds in a tolerance: a window that measures more than 32% on a light meter approved by the Commissioner is conclusively presumed to comply. NCDMV publishes the rule in those practical terms, stating that tinted windows may not measure darker than 32% on an approved meter.
Reflectance may not exceed 20%, and the film must be nonreflective. Red, yellow, and amber films are prohibited.
The legal tint percentage in North Carolina depends on which window you are covering and what you drive.

What changed for vehicle tint on December 1, 2025
Session Law 2025-47 amended several North Carolina transportation statutes. Window tint appears in 3 of them.
Window tint was removed from the annual safety inspection checklist in G.S. 20-183.3(a). Inspection stations no longer measure aftermarket film.
The 10 dollar after-factory tint inspection fee was repealed from G.S. 20-183.7(a). Drivers with tinted windows now pay the same inspection price as every other motorist.
A new duty was added to G.S. 20-127. A driver of a vehicle with tinted windows must lower the driver-side window when a law enforcement officer approaches, and the passenger-side window if the officer approaches from that side.
All 3 changes took effect December 1, 2025, and apply to offenses committed on or after that date.
The legal tint limits themselves were left alone. The 35% standard, the windshield rule, the exemptions, and the penalties all read the same as they did before. Enforcement moved from the inspection station to the roadside.
Windshield tinting rules in North Carolina
The windshield is governed by a location limit. Under G.S. 20-127(b), windshield tint may run along the top of the glass only. It may not extend more than 5 inches below the top of the windshield, or below the AS-1 line, whichever measurement is longer.
The AS-1 line is a small marking etched near the top edge of most windshields by the manufacturer. Where that line sits more than 5 inches down, it becomes the boundary.
Clear film that blocks ultraviolet light is permitted across the full windshield, since it doesn’t reduce visible light transmission.
Which vehicles can have darker rear windows?
G.S. 20-127(c) lists exceptions to the 35% standard. The one that reaches the most North Carolina drivers covers multipurpose vehicles.
The statute defines a multipurpose vehicle as a passenger vehicle designed to carry 10 or fewer passengers that is either constructed on a truck chassis or has special features for occasional off-road operation. Most SUVs, pickup trucks, and vans meet that definition. Any window behind the driver on one of these vehicles is exempt from the light transmission requirement.
Front side windows stay at 35% on every vehicle. SUVs and trucks included.
The statute lists other exceptions:
- Rear windows on property hauling vehicles
- Excursion passenger vehicles, motor homes and limousines
- Ambulances and law enforcement vehicles
- Vehicles registered in another state that meet that state’s tint requirements

Medical exemptions for darker tint
North Carolina issues a permit for drivers with a medical condition that causes photosensitivity to visible light. The process runs through NCDMV’s Medical Review Program.
An applicant completes the Tinted Window Waiver Application, and their examining physician certifies the condition and recommends how long the permit should last. NCDMV issues permits for 2, 3, 4, or 5 years. A permit holder may hold up to 4 valid permits at one time.
Once a permit is approved, NCDMV supplies a sticker that must be displayed in the lower left corner of the rear window. Failing to display it carries a 200 dollar fine.
Penalties for tint that is too dark
A window tint violation is charged as a Class 3 misdemeanor under G.S. 20-127. A criminal charge, not a civil infraction.
The maximum fine for a Class 3 misdemeanor is 200 dollars under G.S. 15A-1340.23. For a driver with no more than 3 prior convictions, the judgment is a fine only.
The statute provides a defense. A driver charged with operating a vehicle with an unlawfully tinted window can answer the charge by removing the film within 15 days and having the window verified as compliant with the Division.
Since tint left the inspection checklist, a traffic stop is now the point where noncompliant film gets identified.
