1. You are circulating in a roundabout and a vehicle is waiting to enter ahead of you. What should you do?
Show answer
Answer D: Keep going, because circulating traffic does not stop for entering vehicles
Stopping in the circle to be polite surprises the drivers behind you and defeats the design; entering traffic is the side that waits.
-
2. The rear of your vehicle begins to slide sideways on a slippery surface. What is the correct correction?
Show answer
Answer C: Ease off the accelerator and steer in the direction you want the front of the vehicle to go
Looking and steering toward your intended path lines the front wheels up with the direction of travel, while sudden braking or a sharp opposite input usually makes the slide worse.
-
3. You are approaching an uncontrolled intersection on a residential street where parked cars hide the cross street. What is the correct approach?
Show answer
Answer B: Slow enough to stop and creep out until you can see
Without a sign or signal you still have to be able to yield, and you cannot yield to traffic you have not seen.
-
4. What is the rule about leaving a child or a pet in a parked vehicle?
Show answer
Answer A: Never do it; the inside can turn deadly hot very quickly
The inside of a parked vehicle heats far faster than the air outside, and cracking a window does not prevent it, so a child or animal must never be left there.
-
5. What injury does a correctly set head restraint help prevent?
Show answer
Answer A: A neck injury of the kind caused when your vehicle is struck from behind
In a rear impact the body is pushed forward and the head restraint stops the head from whipping backward.
-
6. A pedestrian has stepped into a crosswalk at an intersection ahead of you. What is your obligation?
Show answer
Answer C: Yield and let the pedestrian finish crossing before you proceed
Drivers must yield to pedestrians in a crosswalk, and an intersection has a legal crosswalk whether or not lines are painted on the pavement.
-
7. You want to turn left at an intersection with no signs or signals and a vehicle is coming straight toward you from the opposite direction. What must you do?
Show answer
Answer C: Yield and turn after the oncoming vehicle has passed
A driver turning left always gives way to oncoming traffic that is close enough to be a hazard, whether or not the intersection is controlled.
-
8. The vehicle ahead of you has pulled out to pass a truck. May you follow it out and pass as well?
Show answer
Answer B: No, wait until it is done and judge the road for yourself
You cannot see past the vehicle ahead of you, and if it has to abort the pass there is nowhere for either of you to go.
-
9. When is it appropriate to use cruise control?
Show answer
Answer B: On a dry, open highway with light traffic
Cruise control suits steady conditions where you rarely need to change speed. It is a poor choice in traffic, on curves, on slippery roads or when drowsy, because it removes you from the speed decision.
-
10. What does the solid white line running along the right side of a highway mark?
Show answer
Answer A: The right edge of the traveled way
A solid white edge line shows where the traveled way ends on the right, which is particularly useful at night and in poor visibility.
-
11. Why are drivers required to turn the front wheels when parking on a grade?
Show answer
Answer A: So that a vehicle that starts to roll leaves the traffic lanes instead of entering them
The wheel position is a last line of defense if the parking brake or transmission fails, directing the vehicle into the curb or off the roadway.
-
12. The inside of your windshield keeps fogging up on a cold, damp day. What clears it best?
Show answer
Answer B: The defroster with the air conditioning on, which dries the air
Fog on the inside is moisture from the cabin air. The air conditioner dries that air, and the defroster warms the glass, so together they clear it and keep it clear.
-
13. A stop line is painted across the pavement at this sign. Where must the vehicle come to rest?
Show answer
Answer A: Behind the stop line, with no part of the vehicle across it
The vehicle must halt behind the stop line; where no line is painted the driver stops before the crosswalk, and where there is neither, before entering the intersection.
-
14. You find that your shoulder belt has some slack in it. Why does that matter?
Show answer
Answer D: You travel further before the belt restrains you, so injuries are worse
Slack lets your body build up speed before the belt takes hold, which increases the forces on you and the risk of hitting the interior.
-
15. In which situation should you increase your usual following distance?
Show answer
Answer B: On wet roads, at night, in fog, when towing a trailer, or when following a motorcycle
Reduced traction, reduced visibility, a heavier load and a vehicle that can stop faster than yours all require extra space to keep the same margin of safety.
-
16. A pedestrian is crossing at a corner where no crosswalk is painted on the pavement. What is your duty?
Show answer
Answer A: Yield, because a legal crosswalk exists at the corner even without paint
Every intersection has a crosswalk whether or not it is marked, and drivers must yield to pedestrians crossing there.
-
17. Why is an underinflated tire especially risky on a long drive in hot weather?
Show answer
Answer C: It flexes more, builds up heat and can fail at speed
A soft tire flexes on every rotation, and that flexing makes heat that the hot road and high speed add to until the tire can come apart.
-
18. A driver holds a steady highway speed into the section this sign warns about. What is the most likely result?
Show answer
Answer B: The vehicle runs wide toward the outside and can cross into another lane or leave the pavement
Holding speed into a change of alignment asks the tires for more side grip than they can supply, so the vehicle runs wide and the driver is left with less room to correct.
-
19. You are following another vehicle down a long, steep grade. What should you do about the gap?
Show answer
Answer D: Make it longer, because both of you need more room to stop
Everything takes longer to stop on a downgrade, including the vehicle ahead, so the gap that works on the flat is no longer enough.
-
20. You are in the right-hand lane of a multilane street and that lane becomes a right-turn-only lane ahead, but you want to go straight. What should you do?
Show answer
Answer B: Change into a through lane before you reach the markings for the turn lane
A lane-use arrow is a regulatory marking, so a driver who wants to continue straight has to leave that lane before it becomes a mandatory turn lane.
-
21. Where should your hands normally rest on the steering wheel?
Show answer
Answer C: On opposite sides of the wheel, near the 9 and 3 positions
Hands placed opposite each other near the middle of the wheel give smooth, balanced control and keep the arms clear of a deploying air bag.
-
22. Why should a driver crossing several lanes change only one lane at a time?
Show answer
Answer B: Each lane has its own traffic and its own blind spot to be checked
Sweeping across two or three lanes means entering lanes you never checked, so each change gets its own signal, mirror check and head check.
-
23. A pedestrian near the curb is staring at a phone and not looking at traffic. What should you do?
Show answer
Answer A: Slow down and be ready to stop, because the pedestrian may step out without looking
Distracted pedestrians step into the street without checking. Assume they have not seen you and give yourself time and space to stop.
-
24. You are approaching a marked school crossing and children have started to cross the roadway. What is required?
Show answer
Answer A: Stop and let the children finish crossing the roadway
Drivers give way to people in a marked crossing, stopping if that is what it takes, and children in particular may change direction without warning.
-
25. Some drivers believe they can multitask while driving. What does research show?
Show answer
Answer C: The brain switches rapidly between tasks and driving performance suffers
The brain does not truly do two attention-demanding tasks at once; it alternates between them, and the driving task gets less attention each time.
