VLT is the share of light the glass lets through, film and glass together. Source: N.C. Gen. Stat. §20-127, checked Nov 5, 2026. Laws change; confirm with the statute before tinting.
North Carolina regulates window tint through N.C. Gen. Stat. §20-127. Below: the minimum visible light transmission (VLT) for each window, the windshield rule, what counts as too reflective, who can get a medical exemption, and how an officer checks a car at the roadside.
Legal tint limits in North Carolina
- Front side windows: at least 35% VLT.
- Back side windows: at least 35% VLT.
- Rear window: at least 35% VLT.
SUVs, trucks and vans follow a different rule behind the driver: back side windows any darkness and the rear window any darkness.
VLT is measured through film and glass together. Factory glass already blocks some light, usually landing between 70% and 80% VLT before any film, so a roll sold as "35%" on a window that started at 75% ends up darker than 35% once installed. Officers meter the finished window, not the box the film came in.
Windshield
Tint only along the top, no more than 5 inches down or below the AS-1 line, whichever is longer; clear UV-blocking film is allowed anywhere.
Federal standard FMVSS 205 sets the baseline for the glass itself: the windshield and front side windows of a new car must transmit at least 70% of visible light. State law decides what film may be added afterwards, which is why the windshield rule is usually a strip above the AS-1 line rather than a percentage.
Reflective and colored film
Film must be nonreflective and total reflectance may not exceed 20%. Film colors not permitted: red, yellow, amber.
Medical exemptions
North Carolina allows darker tint with a medical exemption. DMV Medical Review Program issues a permit (up to 5 years, max four at once since July 1, 2025) naming the vehicle, windows and levels; carry it in the car and show the DMV sticker in the rear window's lower-left corner ($200 if missing).
Stickers, mirrors and enforcement
No sticker or certificate is required for legal tint. Tinting the rear window does not trigger a second-mirror requirement. Class 3 misdemeanor for driving with or installing noncompliant tint (G.S. 20-127(d)); dismissal if removed within 15 days and certified.
In practice
A meter reading above 32% is conclusively compliant, giving a built-in tolerance on the 35% limit. Windows behind the driver on multipurpose vehicles (10 or fewer passengers on a truck chassis or with off-road features; minivans and pickups count) are exempt, as are limousines, motor homes and vehicles legally tinted in another state. Since Dec 1, 2025 (S.L. 2025-47) tint is no longer metered at the annual safety inspection, but roadside enforcement continues, and drivers with tint must lower the window on the side an officer approaches.

What we don't publish
No reviews, no star ratings, no "best installer" lists. Prices on shop profiles are entered by the owner and checked for format, not negotiated or verified by us; where a shop lists nothing, we say "Quote on request" rather than fill the gap. What a person at Armor Atlas does verify is that the shop exists, installs the service and answers the phone — and that check is dated on every listing.
