S.D. Codified Laws § 32-6B-30
The department shall prescribe, by rule, the size, color, material, and design of dealers' demonstration, in-transit, and temporary forty-five day license permits to be used by dealers licensed under this chapter. Every temporary forty-five day license permit, or dealers' demonstration, or in-transit permit, authorized by this chapter shall show the dealer's license number, which shall be of the dimensions prescribed by the department and shall have a space in which the dealer shall enter in ink the date upon which the vehicle was delivered to the purchaser and other information as the department considers necessary. Any dealer may obtain his required supply of dealers' demonstration or in-transit permits from his own source, but the permit shall conform to the requirements of the department.
