1. Where is the no passing zone pennant sign installed?
Show answer
Answer A: On the left side of the roadway
The pennant is placed on the left side of the roadway at the beginning of the no-passing zone, in the field of view of a driver who is thinking about overtaking.
-
2. You are behind a slow vehicle on a two-lane road and a marked passing lane begins a mile ahead. What is the sensible choice?
Show answer
Answer D: Wait for the passing lane rather than using the opposing lane
A passing lane lets you overtake without ever entering the lane used by oncoming traffic, which is far safer than a pass a minute earlier.
-
3. You are traveling at 55 mph on a rural road and come up behind a horse-drawn buggy. What is the main danger?
Show answer
Answer D: You close on it very quickly because it moves at walking pace
A buggy travels only a few miles an hour, so the gap closes far faster than drivers expect and there is very little time to brake once you see it.
-
4. You realize your tires are running on ice. Which set of inputs is safest?
Show answer
Answer C: Gentle steering, no sudden braking, and no sudden acceleration
Whatever grip is left is used up at once by any sudden input, so every movement of wheel, brake and accelerator must be slow and small.
-
5. In a work zone a flagger signals you to stop, but the sign beside the road says the lane is open. What should you do?
Show answer
Answer C: Obey the flagger
A flagger controls the work zone in real time and the instruction outranks the signs and markings, which cannot reflect what is happening at that moment.
-
6. On loose gravel or deep fresh snow, how does an antilock system affect the stopping distance?
Show answer
Answer D: It can lengthen it, although you keep the ability to steer
On loose surfaces a locked wheel piles up a wedge of gravel or snow that helps it stop, so the antilock stop can be longer even though steering still works.
-
7. You are on a country road with no sidewalk and two people are walking toward you on your side of the shoulder. What should you do?
Show answer
Answer C: Slow down and move over to give them room
Where there is no sidewalk, people are expected to walk on the shoulder facing traffic, and drivers must slow and give them space.
-
8. You are riding a shaded back road in autumn and reach a mat of wet leaves covering the pavement. What should you expect?
Show answer
Answer D: Traction can be nearly as poor as ice, so slow down before you reach them
Wet leaves are slick and they hide whatever is underneath, so reduce speed before the patch and cross it upright without braking or turning.
-
9. An obstacle appears ahead and you can see there is no room left to stop before it. What should you do?
Show answer
Answer D: Swerve around it
Once the distance is too short to stop, changing direction is the only option left, and a motorcycle can change direction faster than it can stop.
-
10. You want to move into the right lane just as an entrance ramp joins the highway at that point. What is the better choice?
Show answer
Answer B: Wait until you are past the merge area so you do not squeeze the entering traffic
The merge area is where ramp traffic has to find a gap, so adding a lane change of your own into the same space creates a conflict.
-
11. Why is the road often most slippery during the first few minutes of rain after a long dry spell?
Show answer
Answer C: Oil and dust on the surface mix with the water into a slick film
Oil drippings and road dust build up on dry pavement, and the first light rain lifts them into a slippery film before heavier rain washes it away.
-
12. How should a riding jacket fit?
Show answer
Answer B: Snug at the neck, wrists and waist so that it cannot balloon open
A jacket closed at the openings stays in place in a fall and does not flap in the wind, which is both tiring and distracting.
-
13. How should the mirrors be set before setting off?
Show answer
Answer B: So that each mirror shows the lane behind and part of the lane beside
Mirrors aimed too far inward show mostly the rider, wasting the view that is meant to cover the traffic behind and to the side.
-
14. Your motorcycle starts to wander while you ride over rain grooves or a bridge grating. What should you do?
Show answer
Answer A: Relax, hold a steady speed and ride straight across
The wandering feeling on grooved surfaces and gratings is unsettling but generally not hazardous, while zigzagging to fight it is far more dangerous.
-
15. A pedestrian starts to cross against a Do Not Walk signal, right in front of you. What should you do?
Show answer
Answer D: Slow or stop and let the person reach safety
Even when a pedestrian is crossing unlawfully, a driver must take reasonable care to avoid hitting that person.
-
16. Where is ice most likely to form first on a cold day?
Show answer
Answer B: In shaded areas and on bridges and overpasses
Shaded spots stay cold longer and bridges and overpasses lose heat from below as well as above, so ice appears there before it appears elsewhere.
-
17. On a regulatory sign, what does a red circle with a diagonal slash drawn over a symbol mean?
Show answer
Answer D: The movement or action shown by the symbol is prohibited
A red circle with a diagonal slash is the standard way of showing that the movement pictured inside it, such as a U-turn or a right turn, is not allowed.
-
18. 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.
-
19. Which action makes a wobble worse instead of better?
Show answer
Answer A: Braking or accelerating to try to ride out of it
Braking or adding power during a wobble can amplify it. Close the throttle gradually, hold the bars firmly and let the speed fall until the machine settles.
-
20. How does a wet road change the distance you need to stop?
Show answer
Answer C: It lengthens it, so you need a much bigger gap ahead
Water between the tire and the road cuts grip, so braking distance grows and the gap that works on dry pavement is no longer enough.
