1. A sign with a yellow background and a black legend generally conveys
Show answer
Answer B: a general warning
Yellow is the background color used for general warning signs, so a yellow sign tells the driver to expect something ahead rather than to obey a rule.
-
2. Approaching the point this sign refers to, which hazard is most likely?
Show answer
Answer A: A vehicle pulling out from the entering road into the driver's path
The main risk is a driver on the entering road who misjudges the gap and pulls out, so covering the brake and being ready to slow is the sensible response.
-
3. Fresh snow covers the road and earlier vehicles have left clear tracks. What line is usually best?
Show answer
Answer B: The existing tracks, where more of the tire can reach the surface
Running in the cleared tracks puts more rubber on the road surface than ploughing through loose snow, provided the tracks have not turned to polished ice.
-
4. Before making a right turn at an intersection, what should you check besides oncoming traffic?
Show answer
Answer B: Your right blind spot and the crosswalk, for cyclists and pedestrians
Right turns often catch a cyclist or a pedestrian coming up on the right, so check the blind spot and the crosswalk before you turn.
-
5. Which clue tells you that a parked vehicle is about to pull into traffic?
Show answer
Answer D: Exhaust smoke, brake lights, front wheels turned out or a driver in the seat
A running engine, lit brake lights, turned wheels or a person behind the wheel all mean the vehicle may move. Slow down and give it room.
-
6. Why is heavy braking a poor idea while two wheels are still on a soft shoulder?
Show answer
Answer B: The two sides have different grip, so the vehicle can pull sharply
With one pair of wheels on pavement and the other on loose material, hard braking slows one side more than the other and swings the vehicle around.
-
7. You have a green light and are turning right. Pedestrians are stepping off the curb into the crosswalk you are about to cross. What should you do?
Show answer
Answer B: Wait and let them cross before completing your turn
A green light does not release a turning driver from yielding to pedestrians already in the crosswalk of the street being entered.
-
8. You are on a two-lane road where a broken yellow line runs on your side of the center. What does that pattern allow?
Show answer
Answer C: Passing when the way ahead is clear and it is otherwise legal
A broken yellow center line marks a stretch where passing is permitted for traffic on that side when it can be completed safely.
-
9. You are waiting to pull out of a driveway when a bicyclist comes along the bike lane in front of you. What must you do?
Show answer
Answer D: Wait until the bicyclist has gone past
A driver leaving a driveway yields to everything already on the road, and a bike lane is part of the roadway.
-
10. A hands free phone conversation is which kind of distraction?
Show answer
Answer C: Cognitive, because your mind leaves the road
Hands free equipment removes the manual and visual parts of a call but not the mental load, and it is the mental load that makes a driver miss hazards.
-
11. 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.
-
12. A trailer that sways badly at speed is often loaded the wrong way. What is the usual fault?
Show answer
Answer A: Too much of the load sits behind the trailer axle
Weight behind the axle lightens the hitch and lets the trailer wag the vehicle. Most of the load should sit ahead of the axle to keep weight on the hitch.
-
13. 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.
-
14. What is the correct technique for backing a vehicle straight?
Show answer
Answer B: Check behind the vehicle before getting in, then turn and look through the rear window while backing slowly
Mirrors and cameras leave gaps close to the vehicle, so walk behind it first, then turn in your seat for a direct view and keep the speed low enough to stop instantly.
-
15. What is wrong with steering through a turn using the palm of one hand on the wheel?
Show answer
Answer D: You have less control and cannot correct quickly if something goes wrong
One-handed palming gives poor leverage and slow response. Use hand-to-hand or hand-over-hand steering with both hands so you can react instantly.
-
16. 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.
-
17. About how far ahead do low beam headlights let you see on a dark road?
Show answer
Answer B: About 250 feet
Low beams light roughly 250 feet of road, and high beams roughly 350 to 500 feet, which sets the limit on a safe night speed.
-
18. May you park in front of a public or private driveway?
Show answer
Answer A: No, blocking a driveway is prohibited even for a short time
Parking in front of a driveway blocks the property owner from entering or leaving, and the prohibition does not depend on how long you stay.
-
19. An ambulance has just gone by and traffic starts to move again. Why should you wait a moment before pulling back out?
Show answer
Answer B: Another emergency vehicle may be following the first one
Emergency calls often bring several vehicles, so check that nothing else is coming before you rejoin the traffic lane.
-
20. How can you check that you are keeping a safe following distance?
Show answer
Answer A: Count at least three seconds between the vehicle ahead passing a fixed object and your reaching it
Pick a fixed roadside object, start counting when the vehicle ahead passes it and make sure at least three seconds elapse before you reach it, adding more time in poor conditions.
