North Carolina Window Tint Law: What Actually Changed in December 2025
North Carolina holds every window on an ordinary passenger car to a minimum of 35 percent visible light transmission, and then does something most states leave to enforcement practice: it writes the enforcement cushion into the statute. A window metering above 32 percent is conclusively presumed to comply. That is why the DMV itself advertises 32 percent rather than 35 as the number to build to. The rule sits in N.C. Gen. Stat. 20-127, and it measures the film and the factory glass together, never the film alone.
The December 2025 change, and the bill almost everyone credits for it
Search interest in North Carolina tint law runs far ahead of every other state, and that is because the law genuinely moved. Session Law 2025-47 took effect on December 1, 2025. It removed window tint from the annual safety inspection and abolished the ten dollar tint inspection fee. It left the 35 percent standard completely untouched. The same act added a duty to lower whichever window a law enforcement officer approaches during a stop, and lifted the cap on concurrent medical exemption permits from two to four.
The bill nearly every summary names for this is Senate Bill 43. That bill passed a first reading in February 2025, was referred to Senate Rules, and never moved again. The provisions became law inside Senate Bill 391, an omnibus transportation act. Coverage describing SB 43 as a bill that scrapped the tint restrictions compounded the error twice over: the bill did not pass, and its text removed the inspection rather than the limits.
What North Carolina is left with is genuinely unusual. Illegal tint is still a criminal offense here, and the annual test that used to catch it is gone. Enforcement is now entirely roadside.
| Glass | Minimum light transmission | Notes |
|---|---|---|
| Front side windows | 35 percent, compliant above 32 | No exemption by vehicle class |
| Back side windows | 35 percent on a passenger car | No limit behind the driver on a multipurpose vehicle |
| Rear window | 35 percent on a passenger car | Exempt on a property-hauling vehicle |
| Windshield | Film limited to the top 5 inches or to the AS-1 line, whichever allows more | Clear UV film permitted across the whole windshield |
| Reflectance | 20 percent or less | Waived for certain vehicle classes |
What a violation costs, and the fifteen day escape hatch
Tint here is a Class 3 misdemeanor, not a civil ticket. The maximum fine is two hundred dollars, and for a driver with no meaningful record the judgment is a fine only. District court costs are charged separately and on top of it. The statute assigns no license points, because this is an equipment offense rather than a moving violation.
The cure defense is worth knowing about before you plead anything. Strip the film within fifteen days of the charge, get a certificate from the DMV or the Highway Patrol confirming the window now complies, and produce it in court or hand it to the prosecutor before trial. The charge does not survive that. Very few states put a documented path like this in the code.
Shops carry their own exposure. Applying film that leaves a window out of compliance is a separate Class 3 misdemeanor for the installer, independent of anything the driver is charged with.
Where the 35 percent floor simply does not reach
Any window behind the driver on a multipurpose vehicle is outside both the transmission limit and the reflectance cap. The statute names minivans and pickup trucks outright and defines the class as a passenger vehicle carrying ten or fewer people that is either built on a truck chassis or has special features for occasional off-road operation. Whether a particular unibody crossover satisfies that test is a per-vehicle question; the statute gives a test, not a model list.
Limousines, motor homes, ambulances, excursion passenger vehicles and law enforcement vehicles go further. Because the statute exempts a window of a limousine rather than a window behind the driver of a limousine, those classes face no transmission or reflectance limit on any glass except the windshield, front doors included.
One rule survives every exemption on that list, and it is the one summaries drop. No film on any vehicle may be red, yellow or amber, and none may be reflective. A pickup can run blackout film on its rear glass and still fail for a colored tint.
The medical permit, and why nobody can quote you a number for it
A driver who is photosensitive to visible light applies to the DMV Drivers Medical Evaluation Program on the Tinted Window Waiver form, with a physician completing the medical section. A permit runs up to five years, covers up to two vehicles per application, has to travel in the vehicle it applies to, and arrives with a sticker that goes in the lower left corner of the rear window between the glass and the film. Four permits may be valid at once since July 2025.
There is no published darkness figure for exemption holders, and that is by design. The permit itself states which windows may be tinted and to what level, so the answer is whatever your permit says. Missing the sticker is separately punishable by a two hundred dollar fine.
Registered somewhere else and driving through? The statute exempts a vehicle registered in another state that complies with the rules of the state it is registered in. Compare against Virginia, Georgia or South Carolina if you are moving rather than visiting, and see every state and province side by side for the full picture.
