Sample speed limits & control questions
According to the South Dakota manual, what conditions are posted speed limits intended for?
- A Nighttime driving with headlights on
- B Summer months on dry pavement
- C Winter conditions with plowed roads
- D Any weather, as long as it is daylight
Show answer
B. Summer months on dry pavement
South Dakota's winter tips say to drive well below the posted limit because posted limits are intended for summer months on dry pavement. On snow and ice it takes much longer to stop and steer.
You are driving much slower than other traffic on a highway. What risk does the manual warn about?
- A Your cruise control may shut off
- B Only that you will arrive late
- C None, because driving slower is always safer
- D You can be ticketed for impeding traffic
Show answer
D. You can be ticketed for impeding traffic
Going much slower than other vehicles is dangerous, and you can be ticketed for impeding traffic. It makes vehicles bunch up and pass you. If a line forms behind you, pull over when safe and let them pass.
When should you slow down for a curve?
- A Before entering the curve
- B After you can see the end of the curve
- C Only if a curve warning sign shows a lower speed
- D In the middle of the curve
Show answer
A. Before entering the curve
Always reduce speed before entering a curve, to a speed that lets you use slight, steady acceleration through it. Slow down more when traction is poor or you cannot see the end of the curve.
A highway posts a minimum speed limit that feels too fast for you. What should you do?
- A Drive on the shoulder at your own speed
- B Use another road
- C Drive below the minimum with hazard lights on
- D Stay in the left lane so others can pass on the right
Show answer
B. Use another road
Some high-speed roads have minimum speed limits, and you must travel at least that fast so you are not a hazard to others. If the minimum is too fast for you, use another road.
