1. You are about to descend a long steep grade. How should you control your speed?
Show answer
Answer D: Select a lower gear before starting down and use the brakes in firm, brief applications
Engine braking in a lower gear carries most of the load down the grade, while continuous brake pressure overheats the brakes and reduces their effectiveness.
-
2. What is the purpose of the engine cut-off switch?
Show answer
Answer B: To stop the engine without letting go of the handgrips
The cut-off switch, usually a red switch near the right handgrip, shuts the engine down while the rider keeps both hands in control of the motorcycle.
-
3. You are driving at night on an unlit road using low beams. How should you choose your speed?
Show answer
Answer C: So you could stop within the distance your headlights light up
Driving faster than you can stop within the lit area is called overdriving your headlights. Anything beyond the beam is invisible until it is too late to react.
-
4. Another driver is behaving aggressively toward you. What should you do?
Show answer
Answer D: Avoid eye contact, give them room to go on their way and do not respond to provocation
Responding to an aggressive driver escalates the conflict, while creating distance and refusing to engage takes you out of the situation. Report serious threats once you can do so safely.
-
5. Which shape is used for the school advance warning sign and the school crossing sign?
Show answer
Answer B: An upward-pointing pentagon
The five-sided pentagon with its point up identifies school signing, so the outline alone tells a driver that children may be present.
-
6. A traffic signal separates you from the rest of your group. What should you do?
Show answer
Answer B: Continue at a safe and legal pace and rejoin the group farther along
Staying with a group never justifies breaking a traffic law, so a separated rider proceeds normally and the group regroups at a planned point.
-
7. Why is it harder for a rider to judge distance and closing speed after dark?
Show answer
Answer D: Only lights are visible, so closing speeds are hard to read
At night you see lights rather than whole vehicles and the scene around them, which strips away the cues that tell you how far away something is and how fast it is closing.
-
8. On a two-lane road with a broken yellow center line, may you cross it to turn into a driveway on the left?
Show answer
Answer C: Yes, when it is safe and the oncoming lane is clear
A broken center line may be crossed for a pass or for a left turn into a road or a driveway, once the oncoming lane is clear.
-
9. A bee gets inside your jacket while you are riding. What is the recommended action?
Show answer
Answer B: Pull off the road and stop before you try to deal with the insect
Being stung hurts, but losing control while swatting hurts much more, so ride to a safe place, stop and then deal with the insect.
-
10. You are following a car at night with the high beam on. What should you do?
Show answer
Answer C: Switch to the low beam so the driver ahead is not blinded
A high beam fills the mirrors of the vehicle ahead and blinds its driver, which is dangerous for the very driver most able to affect the rider.
-
11. When should headlights be switched on besides during the hours of darkness?
Show answer
Answer C: Whenever rain, fog, snow or dust makes it harder to see or to be seen
Headlights are as much about being seen as about seeing, so they go on whenever visibility drops.
-
12. A sign beside the signal reads STOP HERE ON RED. What does it tell you?
Show answer
Answer B: Stop at that point on red, not closer to the intersection
The sign marks the required stopping point, which is set back from the corner so that turning vehicles and sight lines are not blocked.
-
13. Which of these is checked in the Chassis step of T-CLOCS?
Show answer
Answer C: The frame, the suspension, the chain or belt and the fasteners
The chassis step covers the frame and its welds, the front and rear suspension, the final drive and the nuts and bolts holding everything together.
-
14. You are crossing a divided highway with a wide median. How should you treat the two roadways?
Show answer
Answer D: As two intersections, waiting in the median only when your vehicle fits
Each roadway of a divided highway is a separate intersection, and you should wait in the median only if it is long enough to hold your vehicle clear of both roadways.
-
15. Traffic has built up behind you while you wait for a gap to turn left. How should that affect your decision?
Show answer
Answer C: It should not change it; wait for a gap that is genuinely safe
Pressure from behind does not make a small gap bigger, and rushing a left turn across traffic is a common cause of serious crashes.
-
16. The only person offering you a ride home has been drinking. What should you do?
Show answer
Answer B: Do not get in; find another way home
A passenger in an impaired driver's vehicle shares all of the risk and can do nothing about it from the seat, so the only safe answer is another ride.
-
17. 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.
-
18. You reach an uncontrolled intersection at the same moment as a vehicle approaching from your left. What should you do?
Show answer
Answer A: Proceed, but only once you see that driver slowing
You have the right of way over the vehicle on your left, but a right of way is something the other driver has to give, so confirm it before you commit.
-
19. How much space should the leader of a group keep behind the vehicle ahead of the group?
Show answer
Answer D: At least the normal following distance a rider would keep when riding alone
Riding in a group does not shorten the space a motorcycle needs to stop, so the leader keeps the same cushion any rider would keep alone.
-
20. Which ability does alcohol usually affect first?
Show answer
Answer A: Judgment and self control
Alcohol reduces judgment and inhibition before a drinker notices any clumsiness, which is why an impaired driver often feels perfectly capable while already driving worse.
-
21. An entrance ramp joins a highway just before an exit ramp leaves it. What should you expect in that short section?
Show answer
Answer D: Vehicles crossing paths as some enter and others leave
In a weaving section entering traffic moves left while exiting traffic moves right over the same short stretch, so lane changes there need extra room and extra care.
-
22. You brake hard on a wet road and need to steer around a stalled car. How do antilock brakes help you do that?
Show answer
Answer B: They stop the wheels locking, so the tires can still turn the vehicle
Locked wheels slide and cannot change direction. By preventing lockup the system lets you brake at full force and steer at the same time.
-
23. After the leader of a staggered group completes a pass, what should the leader do?
Show answer
Answer A: Move to the left position and hold passing speed to open room for the next rider
Returning to the left position and keeping speed opens the gap the next rider needs to finish the pass and settle back into formation.
-
24. What must a driver be ready to do along the stretch of road where this sign is posted?
Show answer
Answer D: Slow down and stop for a child who steps into the roadway
Children misjudge speed and distance and act without warning, so the driver reduces speed, covers the brake and scans the sidewalks and parked vehicles.
-
25. 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.
