S.D. Codified Laws § 32-30-3.1
If any removal agency as defined by § 32-36-2 removes any unattended motor vehicle from a public street or highway and the removal is not at the written request of the owner, an authorized agent of the owner, or a law enforcement officer, the removal agency shall report the removal to the owner within twenty-four hours of removing the motor vehicle. However, if the removal agency is unable to contact the owner, the removal agency shall report the removal to the county sheriff, if the removal occurred outside any municipality, or to the chief of police, if the removal occurred inside any municipality, within twenty-four hours of removing the motor vehicle. Failure to make a report as provided by this section is a Class 2 misdemeanor.
