S.D. Codified Laws § 32-22-51.2
The unloading of livestock as defined by subdivision 39-5-6(11) is prohibited for the enforcement of violations of §§ 32-22-16 and 32-22-21. The officer shall issue to the driver of the vehicle at the point of violation a special overweight permit for the amount of the overload if the load cannot be adjusted to the legal limits without unloading. The permit authorized pursuant to this section is issued at the flat rate of one hundred dollars for an overweight permit. The flat rate shall include the cost of issuing the permit. This permit authorizes the driver to operate the overweight vehicle to the point of destination within the state or the point of exit from the state. This permit does not, however, exempt the operator from any other enforcement actions.
