1. You are waiting in a left-turn lane at a green light when a fire engine with lights and siren comes toward you in the oncoming lanes. What should you do?
Show answer
Answer D: Hold your position and let the fire engine pass
Turning across the path of an approaching emergency vehicle is exactly what you must not do; stay put until it has gone by.
-
2. You are waiting inside the intersection to turn left when your light turns red. What should you do?
Show answer
Answer A: Complete the turn as soon as the way is clear
Once you have legally entered the intersection you should clear it as soon as the oncoming traffic has stopped, rather than sit in the path of cross traffic.
-
3. Your exit from a three-lane highway is about a mile ahead on the right, and you are in the left lane. What should you do?
Show answer
Answer B: Start moving right now, one lane at a time
Plan ahead and change lanes one at a time well before the exit, so you never have to cut across several lanes at the gore.
-
4. Many signs use a symbol instead of words. The main advantage is that a symbol
Show answer
Answer C: can be read from farther away and by more people
A symbol is recognized at greater distance than a line of text and does not depend on the reader knowing English.
-
5. When should you arrange your way home if you plan to drink?
Show answer
Answer C: Before the first drink
Judgment is the first thing alcohol weakens, so the plan has to be made while you can still make a good one.
-
6. A vehicle in the lane beside you has stopped at a crosswalk. What should you do?
Show answer
Answer C: Stop as well, because that driver may be yielding to a pedestrian you cannot see
The stopped vehicle hides the crosswalk from you, and passing it is a leading cause of collisions with pedestrians who are already crossing.
-
7. Which circumstance can make a South Dakota court condition a DUI defendant's driving permit on participation in the 24/7 sobriety program?
Show answer
Answer C: The defendant had a blood alcohol concentration of 0.17 percent or more, or a prior DUI conviction within the last ten years
The 24/7 sobriety program condition applies when the defendant had a very high 0.17 percent or greater BAC, or has a prior DUI conviction within the past decade.
-
8. Another driver cuts you off and you feel your temper rising. What should you do?
Show answer
Answer A: Take a breath, drop back and let it go, because the whole trip matters more
Retaliation turns a moment of bad driving into a crash, and dropping back costs you only a few seconds.
-
9. Why is following distance measured in seconds rather than in car lengths?
Show answer
Answer A: Because a time gap automatically grows with speed, while a fixed number of car lengths does not
A gap counted in seconds keeps the same margin of reaction time at any speed, whereas a fixed number of car lengths becomes far too small as speed rises.
-
10. What is the proper use of the horn?
Show answer
Answer C: To give a brief warning when another road user may not have seen you
The horn is a warning device meant to alert someone to your presence when a collision is possible, and using it in anger tends to escalate conflict rather than prevent crashes.
-
11. You wait in the aisle with your signal on for a space that is about to be vacated. What is the risk?
Show answer
Answer D: You block the aisle and drivers behind may try to squeeze past
A stopped vehicle turns a two-way aisle into a bottleneck, and drivers who try to get around it pass close to pedestrians and reversing cars.
-
12. You make eye contact with a driver waiting to pull out of a side street. What should you assume?
Show answer
Answer D: The driver may still not have seen you, so stay ready to slow or stop
Drivers can look directly at you and still not register your vehicle, especially a small one. Eye contact helps, but never rely on it.
-
13. A pedestrian is crossing a wide four-lane street and has reached the lanes on the far side. When may you go on?
Show answer
Answer C: Only after the person has finished crossing the roadway
Waiting until the pedestrian has finished crossing is correct in every state and removes any doubt about how much clearance your state demands.
-
14. At a four-way stop another driver pulls out ahead of you when it was clearly your turn. What is the correct response?
Show answer
Answer B: Let that driver go through, then take your turn when the way is clear again
Right of way is something you give, never something you take, so yielding to a driver who takes it wrongly avoids a crash you would otherwise share.
-
15. On an undivided two-lane road you meet a school bus coming toward you with its red lights flashing and its stop arm out. What must you do?
Show answer
Answer C: Stop and wait until the red lights stop flashing
On an undivided road drivers in both directions must stop for a school bus loading or unloading, because children may cross in front of it.
-
16. Which of these is never a legal place to park?
Show answer
Answer C: In a crosswalk, on a sidewalk or within an intersection
Crosswalks, sidewalks and intersections must stay clear so that pedestrians can cross and drivers can see approaching traffic.
-
17. A driver ignores this sign and passes on the opposite side. What is the main risk?
Show answer
Answer B: Ending up on the wrong side of a divider, facing traffic coming the other way
The sign settles which side of a fixed divider is the legal one, so taking the other side sends the vehicle into the opposing stream or straight at the obstruction.
-
18. Which common non-prescription medicine is most likely to make a driver drowsy?
Show answer
Answer C: A cold or allergy remedy containing an antihistamine
Antihistamines in cold and allergy remedies are a leading cause of drowsiness behind the wheel, which is why the label carries a warning.
-
19. At the scene of a crash you were part of, what are you required to do besides stopping?
Show answer
Answer B: Give your name, your address and vehicle details, and help anyone who is hurt
Every state requires drivers involved in a crash to identify themselves and to render reasonable aid to anyone injured.
-
20. Traffic is backed up beyond a railroad crossing. When may you start across the tracks?
Show answer
Answer B: Only when there is room for your whole vehicle on the far side
Never enter a crossing you cannot clear; a vehicle stopped on the tracks in a queue has nowhere to go if the signals start.
-
21. A bicyclist is riding in the middle of a narrow travel lane ahead of you. What is the correct response?
Show answer
Answer D: Slow down and wait until you can pass with wide clearance, changing lanes if needed
A bicyclist has the same right to use the lane as a driver, and a narrow lane may not leave safe passing room, so wait for a gap that lets you move over and pass with a wide margin.
-
22. How long should a young child ride in a rear-facing child seat?
Show answer
Answer D: Until the child outgrows the height or the weight limit of the seat
Rear facing is the safest position and should be kept until the child reaches the top height or weight allowed by the seat.
-
23. You are backing out of a driveway that crosses a public sidewalk. What should you do?
Show answer
Answer C: Stop before the sidewalk and check both ways
Walkers, runners and riders use the sidewalk at speeds that can bring them into your path in a second, so the stop and the look belong before the sidewalk, not after it.
-
24. What is the correct order of steps as you finish parking an automatic on a grade?
Show answer
Answer C: Turn the wheels, set the parking brake, then select park
Setting the parking brake before shifting into park lets the brake take the load, instead of leaving the whole weight of the car on the parking pawl.
-
25. What does a flashing yellow traffic light mean?
Show answer
Answer B: Slow down and proceed with caution
A flashing yellow lets you enter the intersection cautiously after yielding to pedestrians and to conflicting traffic that is already there.
