The real South Dakota knowledge test is the DMV exam used for a learner permit. This page contains one fixed 20 question slice of the full free 180 question bank, with an explanation after each answer.
Sample question from test 4
signs
What does this ONE WAY arrow tell you about traffic on that street?
- Traffic flows only in the arrow's direction
- Drivers may choose either direction after stopping
- The arrow marks a recommended detour
- Only trucks must follow the arrow
Answer: Traffic flows only in the arrow's direction. A one-way sign tells you that traffic is allowed only in the direction shown by the arrow. The detour choice is wrong because South Dakota treats this as direction control, not route advice. The cue is the black arrow paired with ONE WAY; line up your turn or lane position so your vehicle moves with that arrow and never against it.
