Sample questions from this test
For a South Dakota driver 21 or older, what blood alcohol concentration (BAC) is evidence of driving under the influence?
- A 0.02% or more
- B 0.10% or more
- C 0.05% or more
- D 0.08% or more
Show answer
D. 0.08% or more
A BAC of 0.08% or more is evidence that an adult was driving under the influence. You can still be convicted of impaired driving below 0.08%, because impairment starts with the first drink.
What must you do at a flashing red traffic light?

- B Yield only to traffic coming from the left
- C Come to a complete stop, then go when it is safe
- D Slow down and proceed with caution without stopping
Show answer
C. Come to a complete stop, then go when it is safe
A flashing red light means the same as a stop sign. Come to a complete stop, yield to traffic and pedestrians, and go only when it is safe.
You must park on a rural highway. How much road width must be left for other traffic to pass your vehicle?
- A At least 15 feet
- B At least 8 feet
- C At least 20 feet
- D At least 10 feet
Show answer
A. At least 15 feet
If parked on a rural highway, leave at least 15 feet of road width for other traffic to pass. Your vehicle must also be visible for at least 500 feet in both directions, with parking lights and taillights on when it is dark.
What may happen to the fine for speeding in a South Dakota work zone?
- A It is replaced by a written warning
- B It is the same as anywhere else
- C It is reduced if no workers are present
- D It may be doubled
Show answer
D. It may be doubled
Fines for speeding in a work zone may be doubled. Narrow lanes, rough pavement and workers near traffic make speeding there especially dangerous.
You are passing a bicyclist on a highway posted at 55 mph. What does South Dakota law require?
- A At least 6 feet of space, and you may partly cross the center line if safe
- B A light tap of the horn, then pass at any distance
- C At least 6 feet, but you may never cross the center line
- D At least 3 feet of space, staying in your lane
Show answer
A. At least 6 feet of space, and you may partly cross the center line if safe
Above 35 mph the law requires at least six feet of separation. To give that space, you may partially cross the center line or lane line if it can be done safely, and you must keep the gap until safely past.
