The darkest legal tint varies by country and within the US, by state. Generally, the legal limit for window tint is measured by the percentage of Visible Light Transmission (VLT)—which is the percentage of light that's allowed through your car windows. In most US states, the front side windows must have a VLT of at least 50%, but many states allow the rear side and back windows to be darker. It's crucial to check your local laws to ensure compliance and avoid potential fines.
