South Dakota issues 30-day temporary permits for newly purchased vehicles while permanent registration is being completed. Temporary permits are available from licensed dealers and county treasurer’s offices. Because South Dakota plates stay with the owner, private-party buyers must visit the county treasurer before driving. Here is how every scenario works.
How Long Is a South Dakota Temporary Permit Valid?
South Dakota temporary registration permits are valid for 30 days from the date of issue. Within those 30 days, you must complete title transfer and registration at your county treasurer’s office and receive your permanent plates. Temporary permits cannot be extended or renewed — the 30-day limit is fixed.
Who Issues South Dakota Temporary Permits?
Licensed South Dakota Dealers
Licensed South Dakota dealers issue temporary permits at the point of sale. The permit allows you to drive the vehicle while the dealer processes your title paperwork and you complete registration at your county treasurer’s office. Dealers submit title applications on behalf of buyers.
County Treasurer’s Offices
For private-party purchases and other non-dealer situations, county treasurer’s offices issue temporary permits. Visit the office in person with all required documents. The county treasurer is the primary registration authority in South Dakota, not a centralized state DMV.
What If I Buy From a Private Seller in South Dakota?
South Dakota plates stay with the owner. When a private seller sells their vehicle, they remove their plates. The vehicle has no plates when the sale is completed. You cannot legally drive the vehicle on public roads without plates or a temporary permit.
Before or immediately after taking possession of the vehicle, visit your county treasurer’s office to obtain a temporary permit or complete full registration in a single visit.
Documents to Bring to the County Treasurer
- Original title signed and assigned by the seller: all liens released
- Bill of sale with purchase price, date, and odometer reading
- Valid South Dakota driver’s license or state ID
- Proof of current South Dakota liability insurance
- Payment for title transfer fees, registration fees, any applicable county wheel tax, and sales tax
Display Requirements
Display the temporary permit in the rear window of the vehicle so all information is clearly visible from behind. Unlike a permanent metal plate, which is mounted in the rear bracket, the temporary permit is a paper document displayed inside the rear window. All printed information, including the expiration date and vehicle details, must remain legible. Do not fold, cover, alter, or obscure the permit.
New South Dakota Residents
New residents moving to South Dakota must register their vehicles at their county treasurer’s office promptly after establishing residency. Your out-of-state registration and plates remain valid during the transition period. After completing South Dakota registration, South Dakota plates are issued and your out-of-state plates must be removed.
