Sample South Dakota Permit Test Questions

Question 1

When towing a trailer in South Dakota, what must the safety chains or cables be strong enough to do if the regular hitch fails?

  1. A Increase the trailer’s permitted speed
  2. B Control the trailer and prevent the drawbar from dropping to the ground
  3. C Replace the trailer’s service brakes
  4. D Allow passengers to ride in the trailer

Correct answer: B – Control the trailer and prevent the drawbar from dropping to the ground

Safety chains or equivalent devices must have only enough slack for proper turning. They must be connected to the towing vehicle, trailer, and drawbar in a way that keeps the drawbar from falling to the ground if it fails. The chains or cables must also be strong enough to control the trailer after a hitch or coupling failure.

Source: SDCL § 32-19-10 – Safety chain slack and coupling--Violation as misdemeanor

Question 2

What is the safest practice when entering a South Dakota highway work zone?

  1. A Reduce speed and be prepared to stop, even when workers are not visible
  2. B Slow down only when workers are standing in your lane
  3. C Keep your normal following distance to prevent delays
  4. D Ignore temporary signs when construction equipment is not moving

Correct answer: A – Reduce speed and be prepared to stop, even when workers are not visible

Work zones may contain lane closures, rough pavement, equipment, and sudden traffic changes. The driver manual directs motorists to reduce speed, increase following distance, and prepare to stop even when workers are not present. When workers are present in a posted limited-speed work area, the fine for speeding may be doubled, subject to the statutory maximum.

Question 3

Driving much more slowly than surrounding traffic is likely to:

  1. A Create a hazard and cause vehicles to bunch up or pass
  2. B Eliminate the possibility of a collision
  3. C Have no effect on traffic safety
  4. D Always qualify as defensive driving

Correct answer: A – Create a hazard and cause vehicles to bunch up or pass

Going much slower than nearby traffic can cause vehicles to collect behind you and prompt additional passing maneuvers. South Dakota also prohibits driving so slowly that you impede normal and reasonable traffic movement. This rule does not apply when the reduced speed is necessary for safe operation or required by law.

Source: SDCL § 32-25-5.1 – Unreasonably slow speed prohibited--Violation as misdemeanor, South Dakota Driver License Manual — General Driving, “Adjusting to Traffic and Interstate Driving”

Question 4

For a first South Dakota DWI conviction, which consequences are authorized or required?

  1. A Up to one year in county jail
  2. B A fine of up to $2,000
  3. C Driver license revocation for at least 30 days
  4. D All of these choices

Correct answer: D – All of these choices

A first DWI conviction is a Class 1 misdemeanor. That classification authorizes up to one year in county jail, a fine of up to $2,000, or both. The court must also revoke the person’s driver license for at least 30 days and may impose additional restrictions or a longer revocation within the limits established by law.

Source: SDCL § 32-23-2 – Punishment for prohibited driving--First offense--Limited driving privilege, SDCL § 22-6-2 – Misdemeanor classes and penalties--Restitution--Misdemeanor when no penalty imposed

Question 5

When a U-turn is lawful on a multilane divided road, where should you position your vehicle to begin?

  1. A On the right shoulder
  2. B In the leftmost lawful lane or a designated turn lane
  3. C Anywhere in the median
  4. D In any lane without nearby traffic

Correct answer: B – In the leftmost lawful lane or a designated turn lane

A vehicle making a leftward turning movement should approach from the extreme left-hand lane lawfully available or from a designated turn lane. A U-turn may be made only where it is permitted and can be completed safely without interfering with traffic. Do not use the shoulder or an unauthorized part of the median to begin the maneuver.

Source: SDCL § 32-26-18 – Left-turning vehicle--Manner of making turn--Violation as misdemeanor, South Dakota Driver License Manual — General Driving, “Turning and Turnabouts” and “U-Turns”

Question 6

You are traveling 55 mph in the left lane of a 65-mph highway. When could the slow speed be unlawful?

  1. A When poor weather makes the reduced speed necessary
  2. B When it impedes the normal and reasonable movement of traffic
  3. C Never, because driving below the limit is always lawful

Correct answer: B – When it impedes the normal and reasonable movement of traffic

South Dakota prohibits driving at such a slow speed that normal and reasonable traffic movement is impeded. Reduced speed is allowed when it is necessary for safe operation or required by law. On multilane roads, the driver manual also directs slower traffic to use the rightmost travel lane and identifies the left lane as the usual passing lane.
