VLT Compliance Analysis
Visible Light Transmission (VLT) measures the amount of light passing through the glass. In South Carolina, front side window glass must transmit a minimum of 27% light.
Installing a 20% VLT film on front side windows is illegal in South Carolina. You risk a citation fine of $200 fine or up to 30 days in jail (jail is extremely rare). To stay legal, use a film rated 27% VLT or lighter.
Modifier Workarounds & Legal Options
Medical Waiver
South Carolina allows drivers with qualifying medical conditions to obtain an exemption for darker tint.
Net VLT Math
Factory glass is pre-tinted (typically 75% VLT). Adding a 20% film results in a net VLT of 15%, pushing you further under the limit.
Ceramic Film
High-quality clear ceramic films at the legal 27% VLT can block up to 99% UV and 80%+ infrared heat without darkening windows.
