South Carolina Window Tint Laws (2026): Legal VLT Limits
South Carolina Window Tint Laws (2026): Legal VLT Limits
South Carolina requires front side windows to allow at least 27% of visible light through on all vehicle types. Passenger cars must also meet the 27% minimum on back side and rear windows, while SUVs, vans, and pickups can use any non-reflective darkness on the windows behind the driver. Red, yellow, and amber tint are banned statewide.
What is the legal tint limit in South Carolina?
South Carolina sets a 27% VLT minimum on the front side windows for every vehicle class. Whether you drive a sedan, an SUV, a pickup, or a van, the front side glass must transmit at least 27% of visible light.
The distinction between sedans and multipurpose vehicles comes into play on the back glass. For passenger cars (sedans), the 27% rule applies all the way around: front side, back side, and rear window all must let through at least 27% of light. For multipurpose vehicles such as SUVs, vans, and pickup trucks, the windows behind the driver can be any darkness, as long as the film is non-reflective.
A brief explanation of how VLT works: visible light transmission is the percentage of visible light a window lets through. A higher VLT percentage means a lighter, more transparent look. A lower percentage means a darker appearance. South Carolina's 27% is moderately dark and is among the more permissive front-window limits in the southeastern United States.
| Window | Passenger Car (Sedan) | Multipurpose Vehicle (SUV/Van/Pickup) |
|---|---|---|
| Front side | 27% min VLT | 27% min VLT |
| Back side | 27% min VLT | Any darkness (non-reflective) |
| Rear window | 27% min VLT | Any darkness (non-reflective) |
| Windshield | Above AS-1 line only | Above AS-1 line only |
Windshield tint rules in South Carolina
South Carolina permits non-reflective tint on the windshield only above the AS-1 line. The AS-1 line is marked directly on most windshields and typically falls about 5 to 6 inches from the top of the glass. Tint may not extend below that line onto the main viewing area of the windshield.
All tint in South Carolina must be non-reflective, including whatever strip you add to the windshield. Mirrored or metallic film is prohibited on any window. South Carolina also bans specific colors outright: red, yellow, and amber tinted film may not be used on any vehicle window.
These color restrictions apply across all windows, not just the windshield. A film that gives glass a reddish or yellow-amber cast would violate the law regardless of its VLT percentage.
Medical exemptions
South Carolina allows a medical exemption for window tint when a driver or regular passenger has a documented medical condition requiring reduced ultraviolet or visible light exposure. To qualify, a physician must certify the medical need in writing.
Importantly, South Carolina requires that a formal medical exemption certificate be obtained and carried in the vehicle. Simply carrying a doctor's letter is not sufficient on its own. The exemption process involves the required certificate document in a form the Department of Public Safety recognizes.
If you have a condition such as lupus, severe photosensitivity, or a serious ocular disease that requires protection from sunlight, begin the exemption process before installing darker film. Operating a vehicle with non-compliant tint and no formal certificate exposes you to fines and potentially a misdemeanor charge.
How tint is measured and certified
Tint darkness is measured using a VLT meter, a portable device that reads how much visible light passes through the glass. Law enforcement officers can use one during a traffic stop, and installers typically use them to verify compliance before finishing a job.
South Carolina's statute does not specify a measurement tolerance. There is no written buffer above or below the 27% minimum, so a reading that comes in under 27% on the front side glass is a potential violation.
South Carolina requires a certificate of compliance for tinted windows. This certificate must be affixed to each tinted window in the form that the Department of Public Safety prescribes. This is a physical sticker or label on the glass, not just paperwork in your glove box. Make sure your installer provides and applies the required compliance documentation.
Vehicles with out-of-state registration and tint that meets their home state's rules may face scrutiny in South Carolina if the film does not meet the 27% front-side minimum. South Carolina enforces its own standards for vehicles operating on its roads.
Penalties for illegal tint in South Carolina
A violation of South Carolina's window tint law is a misdemeanor offense under S.C. Code 56-5-5015. The penalty is a fine of up to $200 or up to 30 days in jail, or both. This is a more serious classification than the civil infraction approach used in many other states.
The misdemeanor classification means the offense can appear on your criminal record. Multiple non-compliant windows can give rise to multiple charges. South Carolina's enforcement is real, particularly during vehicle stops for other reasons.
The practical resolution is typically to remove the illegal film and bring the vehicle into compliance. But because this is a misdemeanor, it is better to avoid the violation entirely by choosing a legal VLT from the start.
If you want to tint your windows in South Carolina
South Carolina's 27% front-window minimum is workable for drivers who want some privacy and heat reduction. Here is how to navigate the process correctly:
First, identify your vehicle type. If you drive an SUV, van, or pickup, you have full flexibility on the back side and rear windows. Your front side windows must still meet 27% on any vehicle.
Second, choose a film rated at 27% VLT or higher for the front side windows. Many popular films in the 30-35% range are legal. Confirm the exact VLT rating with your installer before purchase.
Third, ensure your installer affixes the required compliance certificate to each tinted window. This is a legal requirement in South Carolina, not just a best practice. Keep the certificate in place throughout the life of the tint.
Fourth, avoid any film with a red, yellow, or amber color cast. Even if the VLT passes the 27% test, a prohibited color makes the film illegal. Stick to standard neutral shades such as gray, charcoal, or bronze.
Fifth, if you have a qualifying medical condition, pursue the formal exemption through the Department of Public Safety before having darker film installed. Carry the exemption certificate in the vehicle at all times.
