To take your permit test in South Dakota, you can simply visit any South Dakota driver license exam station. However, scheduling an appointment online or calling 605-773-6883 can help minimize wait times.

Make sure you have these documents:
- Proof of date of birth, identity, and lawful status in the US (Birth certificate, U.S. passport…). If your legal name differs, provide proof with a marriage certificate or a court order.
- Proof of Social Security number.
- Two proofs of residential address (such as utility or phone bill, mortgage document, or bank statement). If you are minor, a parent/guardian could provide these for you.

The DMV written test in South Dakota is offered in both English and Spanish. It is advisable to have a basic understanding of English since you will find road signs always in English when driving.
The DMV written test covers various topics, such as road signs, parallel parking, turning, passing a vehicle, yielding the right of way, etc. Studying the official South Dakota Driver’s Handbook is the first step to pass the exam because it contains all of this information.
