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 and pickup trucks must also meet the 27% minimum on back side and rear windows, while SUVs, vans, and other multipurpose passenger vehicles 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) and pickup trucks, 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 passenger vehicles such as SUVs and vans, the windows behind the driver can be any darkness, as long as the film is non-reflective; pickup trucks do not get this exemption.

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.

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. Subsection (B) adds a second rule that changes the answer on some vehicles: if the AS-1 line is not visible, no sunscreening device may be applied to the windshield at all.

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's medical exemption runs with the vehicle's registration, not with whoever happens to be riding in it. It covers a motor vehicle registered in this state in the name of a person, or that person's legal guardian, who holds an affidavit signed by a physician or an optometrist licensed to practice in South Carolina stating that the person has a physical condition making the otherwise non-compliant sunscreening material necessary. A frequent passenger who is not the registered owner, or that owner's ward, does not bring the vehicle within the exemption.

The affidavit itself is the required document. It must be kept in the vehicle at all times during operation, produced on request of a law enforcement officer, and updated every two years.

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 qualifying affidavit 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. Under subsection (K), a person who owns or operates a motor vehicle in violation of the section is guilty of a misdemeanor triable in magistrate's court and, upon conviction, must be fined not more than $200 or imprisoned not more than 30 days. The statute is written in the alternative, so a court imposes the fine or the jail term, not 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. A separate and in some ways harsher penalty covers the certificate-of-compliance duties in subsections (E) and (G): a consumer who violates them must be fined not less than $200 or imprisoned not more than 30 days for each offense, and a professional window tinter must be fined not less than $1,000 or imprisoned not more than 30 days, or both, for each offense. 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 or van, you have full flexibility on the back side and rear windows. Pickup trucks do not get this exemption and must meet the 27% minimum on all windows, same as a sedan. 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 and the vehicle is registered in your name or your legal guardian's, have a physician or optometrist licensed in South Carolina sign the required affidavit before having darker film installed. Carry the affidavit in the vehicle at all times and renew it every two years.
