What is the required light transmission percentage for window tinting?

The required light transmission percentage for window tinting typically refers to the minimum percentage of light that must be allowed to pass through the tinted windows. This regulation is important for ensuring visibility both for the driver and for law enforcement officers. A light transmission percentage of 35% means that at least 35% of the available light must be transmitted through the window tint.

This level is chosen to strike a balance between reducing glare and heat from sunlight while maintaining sufficient visibility, which is essential for safe driving. Tints that allow more light to pass through help ensure that drivers can see clearly out of their windows, particularly at night or during poor weather conditions. When window tinting regulations specify a light transmission minimum, they are prioritizing safety by preventing excessively dark tints that could impair visibility.
