S.D. Codified Laws § 32-12-18
No person may apply for any driver license until the licensee surrenders to the Department of Public Safety all valid driver licenses in the licensee's possession issued to the licensee by this state or any other jurisdiction. All surrendered licenses issued by this state shall be canceled and all surrendered licenses issued by another jurisdiction shall be destroyed by the department. The issuing jurisdiction shall be notified that the licensee has applied for a driver license in a new jurisdiction. No person may have more than one valid driver license at any time. If any person, after having surrendered all valid driver licenses in that person's possession, fails to pass the test of that person's ability to read and understand highway signs regulating, warning, and directing traffic, and of that person's knowledge of the traffic laws of this state, then the Department of Public Safety shall issue a temporary permit which entitles the person to continue to drive for a period of thirty days. If an expired driver license is surrendered, the person shall take the knowledge test as required by § 32-12-4.
