When the office has suspended the driving privilege of a person under § 27-16-505, such person shall be required to furnish written proof in the form of a “Restoration to Competency” from the court that declared the person incompetent before the office will consider reinstating the driving privilege. However, when the office has suspended the driving privilege of a person under the provisions of this subsection, such person shall furnish a medical release or statement from a physician licensed to practice medicine in this State before the office will consider reinstating the diving privilege. If the suspension was the result of such person having epileptic seizures, diabetic blackouts, or chronic alcohol/drug/narcotic addiction, then the driving privilege can be restored only after the person has been seizure free and that such condition is under control, has suffered no diabetic blackouts, or is no longer addicted to alcohol/drugs/narcotic for no less than one (1) year and that this period of one (1) year is verified in the form of a physician's statement.
