What is the minimum percentage of glass coating or tint for vehicle windows?

The minimum percentage of glass coating or tint for vehicle windows refers to the level of light transmittance that is required for compliance with regulations. In many jurisdictions, including Texas, the law dictates that certain windows must allow a specific amount of light to pass through to ensure visibility and safety on the road. A tint percentage of 70% means that 70% of visible light is allowed to enter through the window, which strikes a balance between privacy, aesthetics, and visibility.

This standard is intended to prevent excessive darkness of window films, which could impair the driver's ability to see clearly, especially at night or in adverse weather conditions. A percentage lower than this would mean that less light is entering the vehicle, which could lead to visibility issues, especially for the driver, resulting in dangerous driving conditions.

In summary, a minimum of 70% light transmittance ensures that vehicle windows remain safe for operation while also allowing some privacy and style through the use of tinting materials.
