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. Medical authorizations are issued in the name of the person with the condition and are valid as long as the person has the condition or until the vehicle is sold.
It is important to obtain the medical authorization before adding the sun-shading or tinting.
