1. You realize you have just gone past your exit on a freeway. What should you do?
Show answer
Answer C: Carry on to the next exit and turn around there
A missed exit costs a few minutes, while backing up or cutting across the striped gore area puts you in the path of traffic that is not expecting it.
-
2. A sign with a blue background and a white legend and border tells road users about
Show answer
Answer A: services such as fuel, food, lodging, hospitals and rest areas
Blue is the background of the general service series, which points travelers toward the services available along or near the route.
-
3. 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.
-
4. You arrive at an intersection where the traffic signals are completely dark after a power failure. What should you do?
Show answer
Answer A: Treat the intersection as an all-way stop and take turns
When a signal is dark or out of order, drivers on every approach must stop and proceed in turn, exactly as at a four-way stop.
-
5. During the reversing part of a three-point turn, where should you be looking?
Show answer
Answer C: Over your shoulder through the rear window, glancing both ways
You look through the rear window in the direction the car is moving, checking both ways for traffic and people, because mirrors and cameras leave blind areas.
-
6. A black on white regulatory sign at an intersection reads NO TURNS. What may a driver do there?
Show answer
Answer B: Only continue straight through the intersection
The NO TURNS sign bans turns in every direction at that intersection, so the only lawful movement from that approach is straight through.
-
7. A rectangular marker with alternating black and retroreflective yellow stripes set at a slant is used to
Show answer
Answer C: mark an obstruction, with the stripes sloping down toward the side on which traffic should pass
This striped panel is an object marker, and the direction in which the stripes slope shows the driver which side of the obstruction to pass on.
-
8. Which practice matches current child passenger safety guidance?
Show answer
Answer D: Keep a child rear facing until the top height or weight limit of the seat is reached
A rear facing seat spreads crash forces across the child's whole back, so it should be used as long as the seat allows, and never in front of an active passenger air bag.
-
9. You began a turn from the wrong lane and are already inside the intersection. What should you not do?
Show answer
Answer A: Reverse in order to get back into the correct lane
Backing up in an intersection puts you into the path of traffic that cannot expect it; finish the movement and fix your position afterwards.
-
10. You come back to find that your parked car has rolled out into the street. What most likely went wrong?
Show answer
Answer C: The parking brake was not set and the wheels were not turned
The parking brake, a gear or park, and turned front wheels are three separate safeguards, and a runaway means at least the first two were missing.
-
11. How does alcohol affect a driver's ability to handle several things at once?
Show answer
Answer B: It cuts the ability to divide attention between tasks
Driving means watching the road, the mirrors and the instruments together, and alcohol narrows attention so that one of those tasks is dropped without the driver noticing.
-
12. At roughly what speed can hydroplaning begin when a lot of water is lying on the road?
Show answer
Answer C: At speeds as low as about 35 mph
With enough water and less than perfect tread, a tire can start to ride on the water at around 35 mph, well below normal highway speeds.
-
13. What is meant by keeping a space cushion?
Show answer
Answer C: Keeping open space on all sides of your vehicle so you always have somewhere to go
Open space ahead, behind and to the sides gives you time to react and an escape path when a hazard appears, which is the core idea of defensive driving.
-
14. You are ready to pull out of a parallel parking space into the traffic lane. What should you do?
Show answer
Answer C: Signal, check the mirror and blind spot, and wait for a gap
A driver leaving a parking space must yield to traffic already in the lane, so signal, look for the gap and only then move out.
-
15. How much of a traffic lane is a motorcycle entitled to use?
Show answer
Answer D: The full width of the lane
A motorcycle is entitled to the full lane, and riders move within it to stay visible and to avoid surface hazards, so drivers should never try to share a lane with one.
-
16. A motorcycle ahead of you is weaving slightly as it crosses a stretch of grooved pavement. What should you do?
Show answer
Answer D: Give the rider extra room until the surface improves
Grooves, metal plates and loose material affect a motorcycle far more than a car, so back off and let the rider deal with the surface.
-
17. The blue signs mounted before a freeway interchange that carry the logos of individual businesses are
Show answer
Answer C: specific service signs, which show the brands available at that exit
Specific service signs, often called logo signs, list eligible businesses for categories such as gas, food, lodging, camping, attractions and 24-hour pharmacies at the upcoming interchange.
-
18. You have just passed a large truck on the freeway. Why is it dangerous to pull back in front of it and then brake for your exit?
Show answer
Answer B: A loaded truck needs much more distance to stop than a car
A fully loaded tractor-trailer can need the length of a football field or more to stop from highway speed. Cutting in and braking leaves the driver no room to avoid hitting you.
-
19. What should you do before you back out of your own driveway at home?
Show answer
Answer A: Walk around the vehicle and check behind it for children or objects
A small child, a bicycle or a toy can sit entirely inside the blind area behind a vehicle, and a walk-around is the only way to be sure it is clear.
-
20. You come around a bend and find loose sand spread across your lane. What should you do?
Show answer
Answer D: Ease off the gas, avoid sudden braking or steering, and keep straight
Loose material acts like ball bearings under the tires; smooth inputs preserve what little grip remains, while sudden braking or steering breaks it.
-
21. You have stopped at a stop line but parked cars hide the cross street. What comes next?
Show answer
Answer C: Edge forward to where you can see, stopping again if needed
The legal stop at the line is only the first stop; you then move up slowly to a point where you can see, and stop again if traffic requires it.
-
22. In most states, how far before a turn must your signal already be on in city traffic?
Show answer
Answer B: At least 100 feet, roughly the length of six or seven cars
Most states require the signal for at least 100 feet before a turn in city driving, which gives drivers behind you time to react before you slow; several require more at higher speeds.
-
23. You are turning left at an intersection and an oncoming bicyclist is approaching in the bike lane. What must you do?
Show answer
Answer B: Yield and complete the turn only after the bicyclist has passed
A bicycle in the roadway has the same right of way as a vehicle, so a left-turning driver must yield to an oncoming rider just as to an oncoming car.
-
24. A pedestrian is waiting to cross ahead of you and you have slowed down. What helps most?
Show answer
Answer D: Making eye contact, so that you both know you have seen each other
Eye contact confirms that you have seen each other; waving someone across can send them into the path of another vehicle.
-
25. What should you do as you approach your exit from a roundabout?
Show answer
Answer A: Signal right and check the crosswalk for pedestrians before leaving
A right signal tells following drivers and waiting drivers that you are leaving, and pedestrians cross at the exit leg, so the crosswalk must be checked.
