Okla. Admin. Code § 260:135-5-48
Ordinarily, the fitness of an applicant to be granted driving privileges and a driver license can be determined by personnel of Service Oklahoma, as prescribed the Department of Public Safety. However, medical judgment is sometimes necessary to assist in this determination. Medical reports by family physicians or medical specialists may be required as provided by 47 O.S. §6-119. These medical reports may be referred to the Medical Advisory Committee for evaluation and recommendation. The Medical Advisory Committee, as authorized by 47 O.S. §6-118, recommends standards for determining the physical, emotional, and mental condition of a person to safely operate a motor vehicle. Service Oklahoma, in conjunction with the Department of Public Safety makes the final determination in the granting of driving privileges and the issuance of a driver license. Denial or cancellation of a person's driving privileges and driver license by Service Oklahoma may be appealed to the court [47 O.S. §6-211]. Other sections of the Oklahoma Statutes affecting the medical aspects of driver licensing are: 47 O.S. §§6-103(A)(7), 6-113, 6-118, 6- 119, 6-120, 6-207, and 6-209; and 43A O.S. §3-402.
