SDCL § 32-5-120: Special firefighter or advanced life support personnel plates--Surrender upon discharge, separation, or retirement--Exception.

If an advanced life support personnel or emergency medical technician is discharged or retires, or a firefighter is discharged or retires with less than ten years of service, the firefighter, advanced life support personnel, or emergency medical technician must surrender the special number plates identifying the person as a firefighter, advanced life support personnel, or emergency medical technician. The special plates must be surrendered to the secretary, who shall make the necessary changes in the registration file. A firefighter may retain the special number plates if the plates are removed from the vehicle and the secretary is made aware that the firefighter is replacing the plates. The firefighter, advanced life support personnel, or emergency medical technician shall then obtain regular number plates.
