Driving in South Dakota can be an unforgettable experience, especially if you’re crossing the vast plains or winding through the Black Hills. The state is known for its open roads and light traffic, making it ideal for beginners who lack behind-the-wheel experience. However, icy roads and snow can pose a challenge in winter, even for expert drivers. You must always drive cautiously and prioritize safety.

Before you can legally explore South Dakota’s roads behind the wheel of your favorite vehicle, you must complete the Graduated Driver Licensing (GDL) program. Teen drivers begin this program with the instruction permit, which is granted after passing a vision screening and a 25-question knowledge exam. Adults are not required to hold an instruction permit, but they, too, must pass the vision screening and the official knowledge test.

South Dakota’s Department of Public Safety (DMV) publishes the official South Dakota Driver License Manual (South Dakota DMV Handbook (SD Driver's Manual) 2025). This resource describes the various aspects of driving theory in detail, helping you understand what it takes to become a safe and responsible driver. However, some students find active learning easier and more efficient than traditional study methods. They use practice tests to boost their learning potential and retain information through repetition. You can adopt a similar approach by incorporating our South Dakota DMV Written Test Study Guide practice test into your study routine.
