South Carolina window tint laws set the front side window minimum at 27% VLT for every vehicle type. The rear-most window follows a separate rule under Code Section 56-5-5015. A vehicle owner who violates the rule faces a fine of at least $200. A professional tinter faces a fine of at least $1000. Red, yellow, and amber tint are banned statewide.
What Is VLT and Why It Matters
VLT stands for visible light transmission. It measures the percentage of outside light that passes through the combined glass and film on a vehicle window. A higher VLT number means more light gets through, so the window looks lighter and more see through. A lower VLT number means the window is darker and closer to the legal floor set in Code Section 56-5-5015.
The AS-1 Line Explained
The AS-1 line is a marking etched near the top of most factory windshields. Code Section 56-5-5015 allows a nonreflective sunscreening device only above this line, and the film may not extend downward past it. If the AS-1 line is not visible on a windshield, the statute does not permit any sunscreening device there. This line traces back to a federal glazing marking standard.
Sunscreening Device and Certificate of Compliance
Code Section 56-5-5015 uses the term sunscreening device for any tint film applied to vehicle glass. The statute requires that products sold or used in South Carolina come with a manufacturer certificate of compliance. That certificate must be affixed to the tinted glass in the form the state prescribes. It functions as a physical label on the window, not paperwork kept separately.
What South Carolina Law Requires
The core rule under South Carolina Code Section 56-5-5015 on sunscreen devices covers the windshield, front side wings, side windows next to the driver, and windows behind the driver. If no aftermarket device has been added to a window, the transmission provisions do not apply at all. Factory glass alone, even if darker, is not a violation under this section.
Legal VLT Limits by Window
The front side windows next to the driver must combine with any factory tint to reach at least 27% VLT. This floor applies to the side windows immediately right and left of the driver. The rear-most window follows its own provision. A device applied there must be nonreflective and reach at least 27% VLT, and using it requires both a right and a left outside mirror.
Windshield Strip Rule
A sunscreening device on the windshield may only be used along the top portion, above the AS-1 line, and it may not extend downward past that line. The statute treats this as a placement restriction rather than a percentage threshold, so even a very light film is prohibited below the marked line. No device may be applied at all if the AS-1 line cannot be identified.
Reflectivity and Color Restrictions
Every device installed under Code Section 56-5-5015 must be nonreflective, meaning the material absorbs light rather than reflecting it outward. Metallic or mirror finish films that bounce light toward other drivers fail this rule regardless of VLT percentage. The statute also bans red, yellow, and amber tint on any window. Other colors such as charcoal, bronze, or blue shaded film remain permitted if VLT and reflectivity rules are met.
Who the Tint Rules Apply To
Code Section 56-5-5015 applies to any motor vehicle required to be registered in South Carolina and operated on a public highway, road, or street. The statute does not create a separate lighter standard for larger vehicles on the front windows. Every vehicle class must meet the same 27% front side window floor, and the real distinction only appears for windows located behind the driver.
Passenger Cars
For a passenger car such as a sedan, coupe, or wagon, the 27% floor in Code Section 56-5-5015 applies to the front side windows, and the rear-most window follows the separate rear window provision described above. Passenger car owners cannot rely on a looser standard for any window position. This uniform treatment across the vehicle differs from states that apply looser rules to larger vehicle classes.
SUVs, Vans, and Pickup Trucks
Multipurpose vehicles including SUVs, vans, and pickup trucks must meet the same 27% front side window standard as passenger cars. The meaningful difference for these vehicle types involves windows located behind the driver, where secondary sources commonly describe more flexibility for larger vehicles. Readers should treat the statute language itself, not a vehicle type assumption, as controlling for any specific window position.
Certificate and Documentation Requirements
South Carolina requires that sunscreening devices sold or installed in the state include a manufacturer certificate of compliance. Code Section 56-5-5015 states the certificate must be affixed permanently to the tinted glass rather than stored separately. A vehicle owner who receives tint work without a properly affixed certificate has not met the documentation requirement, independent of whether the film meets the VLT threshold.
Medical Exemption Affidavit Process
Code Section 56-5-5015 allows an exemption for a vehicle registered to a person, or that person’s legal guardian, who has an affidavit from a licensed physician or optometrist. The affidavit must state that a physical condition makes darker material necessary. It must stay in the vehicle at all times and be shown to an officer on request, and it must be updated every two years to remain valid.
Penalties for Violating the Tint Law
Code Section 56-5-5015 treats a violation as a misdemeanor triable in magistrate’s court rather than a simple fix-it ticket. The statute separates the penalty structure by who committed the violation. This distinction is frequently missing from other summaries, even though the difference in exposure between a vehicle owner and a professional installer is significant and written directly into the statute.
Penalties for Vehicle Owners
A consumer who violates the sunscreening device or certificate provisions of Code Section 56-5-5015 is guilty of a misdemeanor triable in magistrate’s court. Upon conviction, the statute sets a fine of not less than $200 or imprisonment of not more than 30 days for each offense. Because the fine is stated as a minimum, a court retains discretion to impose a higher amount depending on the circumstances.
Penalties for Professional Window Tinters
A professional window tinter, defined under the statute as a person who installs sunscreening devices for profit, faces a higher penalty. Upon conviction, a professional tinter must be fined not less than $1000 or imprisoned not more than 30 days, or both, for each offense. This structure means a business installing noncompliant film repeatedly carries far greater exposure than a single vehicle owner cited once.
Exceptions and Limitations
Several exceptions and clarifications appear directly in Code Section 56-5-5015 that change how the general darkness rules apply to a specific vehicle or driver situation across the entire state. These provisions matter because they determine whether the transmittance requirements are triggered at all, or whether an otherwise darker vehicle window still remains fully compliant with the statute as written today.
Factory Glass With No Aftermarket Film
If a vehicle owner has not added any aftermarket sunscreening device to a window, Code Section 56-5-5015 states that the light transmittance provisions of the section do not apply. Factory installed tinted glass, even measuring below 27% VLT on its own, is not treated as a violation as long as no film has been added on top of it. The rules are triggered specifically by aftermarket addition.
Medical Exemption Details
Beyond the general 27% standard, Code Section 56-5-5015 provides a defined path for a medical exemption tied to a documented physical condition. The exemption requires a signed affidavit from a physician or optometrist licensed in South Carolina, kept in the vehicle and updated every two years. This exemption is specific to a vehicle registered in the exempted person’s name and does not automatically transfer to a different vehicle.
Common Misconceptions About South Carolina Tint Law
Several misunderstandings about South Carolina’s tint rules persist because secondary sources often simplify the statute in ways that lose important legal detail entirely for readers. Two of the most common points of confusion involve how the VLT percentage scale actually works and how the rear-most window provision differs from the front side window rule described earlier in this guide above.
Lower VLT Number Confusion
Some drivers assume a lower VLT percentage indicates a safer or more compliant tint, when the opposite is true under Code Section 56-5-5015. A lower VLT number means less light passes through the window, so the tint is darker and sits closer to the legal floor rather than further from it. The 27% figure in the statute is a minimum, not a target darkness level.
Rear Window VLT Nuance
Many competing summaries state the rear-most window follows the identical flat 27% rule used for front side windows, but Code Section 56-5-5015 treats it as its own distinct provision. That provision requires nonreflective film reaching at least 27% VLT when a single device is used, and it separately requires both a right and a left outside mirror whenever that device is installed. This mirror requirement is often overlooked.
Pending Legislative Activity to Watch
South Carolina lawmakers have introduced multiple bills in recent sessions proposing to revise the light transmission levels set in Code Section 56-5-5015. As of this writing, these proposals remain pending and have not been enacted into the current code, so the 27% figures in this guide reflect the law currently in force. Laws and enforcement may change, and readers should check official state sources for the latest rules.
South Carolina window tint laws place clear numeric limits on darkness, reflectivity, and color, backed by a misdemeanor penalty structure that treats owners and installers differently. Readers considering aftermarket tint should confirm current requirements against the statute or with a licensed professional before installation, since a certificate of compliance and correct AS-1 placement are both independently enforceable.
