Free Online DMV Written Test Practice for South Dakota (2025)

Savoring the sights from Needles Highway, the Peter Norbeck Scenic Byway, and the Spearfish Canyon Scenic Byway. The exciting nightlife and social scenes in Sioux Falls and Rapid City. Commuting to work in agriculture, healthcare, or manufacturing via the comfort and convenience of your vehicle. If you want to see more of “Great Faces and Great Places,” there’s no better way to do it than by driving yourself. But to do that legally, you must obtain and hold a driver’s license.

To obtain a license, you must meet a series of requirements. One of the most crucial is to pass the official South Dakota DMV written knowledge test, which covers South Dakota’s rules of the road and safe driving practices. All aspiring drivers, regardless of their age, are required to pass this test. If you’re under 18 or need to practice driving under supervision, passing the knowledge test is also a key requirement for obtaining an instruction permit. This credential will allow you to practice supervised driving as you prepare to pass the driving (road) test for a license.

The knowledge test consists of 25 questions and has a passing score of 80%. The test is based on the official driver’s manual (South Dakota DMV Handbook (SD Driver's Manual) 2025). The DMV urges you to study this manual. Nevertheless, a whopping 70% of applicants reportedly failed the South Dakota knowledge test on their first try.

We have created a test preparation program with a set of tools to help you pass the knowledge test. This is the second of our five South Dakota Permit Practice Tests. We designed it to help aspiring drivers like you pass the DMV knowledge test on their first try. Like the official knowledge test, this practice test is based on the official South Dakota driver’s manual, and it’s up to date as of October 2025. All practice questions are multiple choice. You must choose the best or most complete answer for each question.

Our AI Assistant can help you with any practice question. It can rephrase the question, supply a hint, or answer your own questions about driving. If you still miss the question, the AI Assistant will immediately tell you and explain the correct answer.

Finally, we also offer our own South Dakota Permit Test Study Guide to help you prepare for the day of the South Dakota written test. It covers how to prepare yourself physically and mentally for the test, what documents to take to the DMV, and what fees you may have to pay, among other topics.
