1. A yellow pennant-shaped sign is posted on the left side of a two-lane road facing you. What is it telling you?
Show answer
Answer B: You are entering a no-passing zone and may not start a pass
The pennant is placed on the left so that it faces the driver who might pull out, and it marks the beginning of a no-passing zone.
-
2. Your car has side curtain airbags. What should you avoid doing?
Show answer
Answer B: Resting your head against the window or the door pillar
A side airbag deploys from the pillar or roof rail, so a head leaning against that area is directly in its path.
-
3. You are already inside an intersection when you realize you should be in the lane beside you. What should you do?
Show answer
Answer C: Stay in your lane through the intersection and change lanes afterwards
Drivers in an intersection are watching for cross traffic and turning vehicles, so an unexpected sideways move there is easily missed.
-
4. A police officer is directing traffic at an intersection and waves you through a red light. What should you do?
Show answer
Answer C: Follow the officer, whose directions come before signs and signals
Directions given by a police officer or an authorized flagger override signs, signals and pavement markings.
-
5. You are parking on a hill where there is no curb, whether facing up or down. Which way should the front wheels point?
Show answer
Answer B: Toward the shoulder, so the vehicle would roll away from the traffic lanes
With no curb to stop the vehicle, the wheels are turned toward the edge of the road so that a runaway vehicle leaves the roadway instead of entering it.
-
6. A sign on a freeway restricts trucks to the two right-hand lanes. What should a car driver expect in those lanes?
Show answer
Answer A: More heavy vehicles and slower changes of speed
A truck lane restriction concentrates heavy vehicles on the right, and those vehicles accelerate, brake and change lanes far more slowly than cars.
-
7. You are backing straight down a driveway while looking over your right shoulder. Where should your left hand be?
Show answer
Answer C: At the top of the steering wheel, holding it with a firm grip
With one hand at the top of the wheel you can hold a straight course and make small corrections while your body is turned to look behind.
-
8. A yellow diamond showing the silhouette of a deer warns that
Show answer
Answer D: large animals may cross the road in that area
The sign marks a stretch where animals are known to cross, so drivers should reduce speed and scan both roadsides, especially around dawn and dusk.
-
9. A yellow horizontal rectangular sign showing one large arrow pointing left or right, facing traffic on the far side of a sharp bend, tells the driver
Show answer
Answer C: which way the roadway turns at that point
The large arrow sign is mounted on the outside of a sharp change in alignment so that a driver approaching head on immediately sees which way the road goes.
-
10. What is threshold braking?
Show answer
Answer C: Braking hard but staying just short of locking the wheels
A rolling tire grips better than a sliding one, so the shortest stop comes from pressure held just below the point where the wheels lock.
-
11. A reduced speed limit posted with this sign and a plaque giving hours is in force
Show answer
Answer C: during the hours shown on the plaque, or while the beacon is flashing
A school speed limit applies during the periods stated on the plaque or while the attached beacon flashes, and the regular limit governs outside those periods.
-
12. How far ahead should you normally be looking as you drive?
Show answer
Answer C: About 12 to 15 seconds ahead, well beyond the vehicle in front
Looking that far down the road lets you see a problem developing and slow smoothly, instead of discovering it in time only for hard braking.
-
13. The green arrow protecting your turn changes to a steady yellow arrow. What is it telling you?
Show answer
Answer A: The protected turn is ending and you should prepare to stop
A steady yellow arrow warns that the arrow movement is being terminated and that a red indication will follow.
-
14. How does marijuana affect a driver?
Show answer
Answer C: It slows reaction time and impairs judgment of time and distance
Marijuana impairs coordination, attention and the ability to judge speed and distance. Driving while impaired by it is illegal everywhere, even where its use is legal.
-
15. An emergency vehicle with flashing lights and a siren is approaching from behind on a two-way street. What should you do?
Show answer
Answer C: Pull over to the right edge of the road and stop until it passes
Clearing a path by pulling to the right and stopping gives the emergency vehicle a predictable route, while stopping in mid-lane or inside an intersection blocks that path.
-
16. You are waiting to turn left and a motorcycle is approaching from the opposite direction. Why should you take extra care judging its speed and distance?
Show answer
Answer A: Its small size makes it look farther away and slower than it really is
A motorcycle's narrow profile fools the eye, so drivers often misjudge how soon it will arrive. Left turns across an oncoming motorcycle are a leading cause of rider deaths.
-
17. Below a speed limit sign is a smaller panel with white numbers on a black background and the word NIGHT. What does it show?
Show answer
Answer D: The limit that applies after dark
A night speed limit panel sets a separate legal maximum for the hours of darkness, and its reversed colors mark it as the night figure.
-
18. At a freeway exit ramp, this sign normally backs up which other regulatory sign posted nearer to the ramp terminal?
Show answer
Answer D: The sign that forbids entering that roadway at all
The two work as a pair at ramp terminals: one keeps drivers from turning in, and this one sits farther along to catch a driver who has already entered.
-
19. Every signal head at an intersection is flashing red in all directions. How should you treat the intersection?
Show answer
Answer C: As an all-way stop, stopping and then going in turn
Red flashing in every direction means each approach must stop, so the intersection works exactly like an all-way stop.
-
20. A sign on a divided highway reads Keep Right Except to Pass. What does it require of you?
Show answer
Answer A: Use the left lane only to overtake, then return to a lane on the right
The left lane on such a highway is reserved for overtaking, so a driver who has finished a pass must move back to the right.
-
21. A sign at the approach to a bridge reads WEIGHT LIMIT 10 TONS. What does the figure set?
Show answer
Answer B: The heaviest vehicle the bridge may legally carry
A weight limit sign is a regulation based on what the structure can bear, and it applies to the loaded weight of the whole vehicle.
-
22. Along a highway the reference markers count upward as you travel. Where does the numbering normally begin?
Show answer
Answer C: At the southern or western edge of the state
Mileage numbering starts where the route enters the state from the south or the west, so rising numbers tell a driver which way they are heading.
-
23. How far should the driver chest be from the steering wheel?
Show answer
Answer B: At least about ten inches
The airbag deploys with great force in the first instants of a crash, so about ten inches between your chest and the wheel is the recommended minimum.
-
24. Why does the speed of the right-hand lane of a freeway change so often?
Show answer
Answer B: Vehicles entering and leaving the highway all use that lane
Entrance and exit ramps feed into the right lane, so traffic there is constantly slowing to leave or speeding up to join.
-
25. The circular sign shape is reserved for which warning?
Show answer
Answer C: Advance warning of a highway-rail grade crossing
A round yellow sign with a black X and the letters RR is the grade crossing advance warning sign, and the circular outline is used for no other message.
