1. The added lane warning sign tells a driver that
Show answer
Answer A: an extra lane begins ahead, so entering traffic does not have to merge into an existing lane
Where a lane is added, traffic entering the roadway gets a lane of its own, so merging is not required, although drivers should still watch the vehicles beside them.
-
2. A lane control sign over one lane shows both a straight arrow and a left arrow. What does it tell drivers in that lane?
Show answer
Answer A: Either movement may be made from that lane
An optional movement lane control sign lists every movement permitted from the lane, so a driver may choose any arrow shown.
-
3. Can a driver be charged with impaired driving after taking a legal over the counter medicine?
Show answer
Answer C: Yes, if the medicine impairs the ability to drive safely
Impaired driving laws cover any substance that affects driving, including cold remedies, allergy pills and sleep aids sold without a prescription.
-
4. You are very angry after an argument and about to drive. What should you know?
Show answer
Answer A: Strong emotions can impair judgment and attention much like alcohol
Anger, grief and stress pull attention inward and encourage risk taking. Give yourself time to settle down before getting behind the wheel.
-
5. A small plaque mounted under this sign shows a numeral such as 2 or 3. What does that numeral report?
Show answer
Answer A: How many sets of tracks the crossing carries
The plaque states the number of tracks at that location, which is a warning that a second train may be running on another track behind the first.
-
6. What does the choke, or enrichener, do on a motorcycle that has one?
Show answer
Answer B: It gives the engine a richer fuel mixture so a cold engine will start
A cold engine needs more fuel in proportion to air, and the choke supplies that richer mixture until the engine warms up.
-
7. What must a driver be ready to do along the stretch of road where this sign is posted?
Show answer
Answer D: Slow down and stop for a child who steps into the roadway
Children misjudge speed and distance and act without warning, so the driver reduces speed, covers the brake and scans the sidewalks and parked vehicles.
-
8. A rider in the middle of the group pulls over onto the shoulder. What should the sweep rider do?
Show answer
Answer C: Stop and stay with that rider while the rest of the group continues
The sweep exists so that no rider is ever left alone at the roadside, while the remainder of the group carries on to a safe place to wait.
-
9. How does South Dakota law distinguish a license revocation from a license suspension?
Show answer
Answer D: A revocation ends the driving privilege and requires a new application, while a suspension is a temporary, sometimes conditional withdrawal
Revocation terminates the driving privilege and license outright, while suspension is described as a temporary withdrawal that can be time-limited or conditional.
-
10. Which statement about standard drinks is correct?
Show answer
Answer C: A standard serving of beer, of table wine and of distilled spirits each contain about the same amount of pure alcohol
Roughly 12 ounces of regular beer, 5 ounces of table wine and 1.5 ounces of 80 proof spirits each contain about the same amount of pure alcohol, so the type of drink does not change the effect.
-
11. You notice that the driver ahead of you is holding a phone to the ear. What should you do?
Show answer
Answer C: Assume slower reactions and leave extra space, or else hold back
A driver on the phone reacts late and misses things, so the safe response is distance rather than a lesson.
-
12. Why would a restriction like this one be applied to a stretch of road?
Show answer
Answer A: Because there is not enough visible road ahead to complete a pass safely
Limits on overtaking are set where a hill, a curve or an obstruction leaves too little sight distance for a driver to pull out, pass and return before meeting oncoming traffic.
-
13. What audibility standard does South Dakota law set for a vehicle's horn?
Show answer
Answer C: Audible from at least 200 feet under normal conditions
State law requires a horn capable of being heard from at least 200 feet away under normal conditions.
-
14. The signal turns green as you approach an intersection. What is the safest practice?
Show answer
Answer B: Look left, then right, then left again, and make sure the intersection is clear before entering
A green light gives permission but does not guarantee the intersection is empty, and a quick scan catches a vehicle running the red or a pedestrian still crossing.
-
15. At a four-way stop you and an opposing driver arrive together. You are going straight and the other driver is turning left across your path. Who goes first?
Show answer
Answer B: You do, because the left turn crosses your path
When two opposing drivers arrive together, the one going straight goes first and the left-turning driver yields.
-
16. Why is passing on a curve prohibited even when the traffic seems light?
Show answer
Answer C: You cannot see far enough around it to know the lane is clear
A pass is only as safe as the distance you can see, and a curve hides the very lane the maneuver uses.
-
17. Your left-turn lane faces a steady green ball and oncoming traffic is heavy. What are you allowed to do?
Show answer
Answer C: Move into the intersection and turn when a safe gap appears
A green ball permits the turn but gives no priority, so you may move into the intersection and wait there for a gap in the oncoming traffic.
-
18. You have stopped after a crash. Why should the engines of the vehicles involved be switched off?
Show answer
Answer A: To reduce the risk of a fire starting around any fuel that has spilled
Crashes often break fuel lines, and a running engine is a source of ignition, so switching off lowers the risk of fire.
-
19. You are approaching a multilane roundabout. When should you choose your lane?
Show answer
Answer C: Before you enter, using the lane-choice sign on the approach
You select your lane on the approach the way you would at any multilane intersection, then stay in that lane all the way around, because changing lanes inside a roundabout creates side-impact conflicts.
-
20. Your navigation device tells you to turn where a road sign says the turn is closed. What should you do?
Show answer
Answer B: Follow the signs and what you can see
A device works from stored data that can be out of date, while signs and the road in front of you show the situation now, so the road wins every time.
-
21. You are driving through a residential area where parked cars hide the side streets. What is the safest approach?
Show answer
Answer C: Slow down and cover the brake as you pass each opening
Where parked vehicles hide side streets and driveways, lower speed and a covered brake buy the time you lose in sight distance.
-
22. What kind of sole and heel suit motorcycle boots?
Show answer
Answer A: A hard, slip resistant sole with a low heel that will not catch
Boots have to grip the pavement when you put a foot down and grip the footrests while you ride, and a tall heel can catch on the ground or on the machine.
-
23. How should a riding jacket fit?
Show answer
Answer B: Snug at the neck, wrists and waist so that it cannot balloon open
A jacket closed at the openings stays in place in a fall and does not flap in the wind, which is both tiring and distracting.
-
24. There is a stop sign but no stop line and no crosswalk. Where must you stop?
Show answer
Answer A: Before entering the intersection, where you can see cross traffic
With no line or crosswalk, stop before you enter the intersection at the point where you can see traffic on the cross street.
-
25. A steady downward green arrow is displayed over a lane. What does it indicate?
Show answer
Answer C: The lane is open to traffic in your direction
A steady downward green arrow means the lane it points to is open to traffic traveling in your direction.
