Vehicle Sun-Shading Medical Authorization

Medical Authorization

DMV issues medical authorizations to individuals with medical conditions that require protection from sunlight or bright artificial light. The medical authorization allows these individuals to equip their vehicles regularly used to transport them with window tinting films or applications.

It is important to obtain the medical authorization before adding the sun-shading or tinting.

Sun-shading waivers are valid until the vehicle is sold to another person or until the medical condition no longer exits, whichever occurs first. The sun-shading must be removed from the vehicle at that time.
