To operate a motor vehicle, a driver shall possess certain physical and mental abilities. The first and primary purpose and intent of Service Oklahoma is to license new applicants and to renew driver licenses of persons with these abilities but, when necessary and upon the recommendation of the Department of Public Safety, to restrict, deny, cancel, or disqualify the driving privilege of those applicants or licensees who present an unwarranted risk or do not meet the minimum standards. The standards and rules included in this Part are created upon the recommendations of the Department of Public Safety.
