All residents who operate a motor vehicle on any South Dakota street or highway must have an South Dakota driver’s license or learner's permit. To obtain an instruction permit, you must be at least 14 years of age and pass the vision and knowledge test. The South Dakota written test covers the contents of the South Dakota Driver's Manual, and includes questions on safe driving practices, road rules, road signs and signals. The SD DMV knowledge test consists of 25 questions, and you must score 80% or higher (at least 20 correct answers) to pass.
