S.D. Codified Laws § 58-11-9
No policy insuring against loss resulting from liability imposed by law for bodily injury or death suffered by any person arising out of the ownership, maintenance, or use of a motor vehicle may be delivered or issued for delivery in this state with respect to any motor vehicle registered or principally garaged in this state, except for snowmobiles, unless coverage is provided therein or supplemental thereto in limits for bodily injury or death equal to the coverage provided by such policy for bodily injury and death, for the protection of persons insured thereunder who are legally entitled to recover damages from owners or operators of uninsured motor vehicles and hit-and-run motor vehicles because of bodily injury, sickness, or disease, including death, resulting therefrom. However, the coverage required by this section may not exceed the limits of one hundred thousand dollars because of bodily injury to or death of one person in any one accident and, subject to the limit for one person, three hundred thousand dollars because of bodily injury to or death of two or more persons in any one accident, unless additional coverage is requested by the insured. Any policy insuring government owned vehicles may not be required to provide uninsured motorist coverage.
