Window tinting in South Carolina
South Carolina heat is close to the Gulf. The legal line is 27%, so a 30% or 35% shade is the practical choice, not 5%.
In South Carolina, front side windows must let at least 27% of visible light through. Rear glass must let at least 27% of visible light through. Windshield film stays a clear strip at the top, not a full tint. House and storefront film is not held to that driving rule. This is a summary of published limits, not legal advice.
