What type of film must be installed on the front windshield without the need for medical exemptions?

Clear UV film is specifically designed to block harmful ultraviolet rays without affecting the visibility of the driver's view out of the windshield. This type of film does not introduce any tint or color that would impede the driver's ability to see clearly and does not require a medical exemption for installation. It is important in maintaining safety while driving, as it allows for normal light transmission while still providing protection against UV radiation.

In contrast, colored film, reflective film, and dark tint film may affect visibility and could potentially violate Texas laws concerning windshield tinting. These types often require medical exemptions due to their capacity to alter the amount of light that enters the vehicle, hindering a clear view and leading to dangerous driving conditions. Therefore, the installation of clear UV film is not only permissible but is also a practical choice for enhancing passenger comfort without compromising safety.
