(a) The Alabama State Law Enforcement Agency (ALEA), upon application from a person required for medical reasons to be shielded from the direct rays of the sun, may issue an exemption from this chapter for any motor vehicle owned by the person or in which the person is a habitual passenger. The application shall be supported by written statement of that fact from a physician licensed to practice medicine in this state. Except as otherwise provided in subsection (b), the exemption may be issued with the conditions and limitations prescribed by ALEA.
(b) An exemption granted pursuant to subsection (a) to persons with light-sensitive prophyria shall apply to all areas of the windshield and windows prescribed by the physician in the written statement submitted as part of the application.
(c) ALEA shall design a decal with a unique identification number to be issued to each person granted an exemption pursuant to this section. The decal shall be placed on the windshield of each motor vehicle operated by the exempt person. The department may charge a reasonable fee for each decal issued. The proceeds of the fee shall be used by the department to defray the costs of designing the decal and administering the exemption process.
