1. Why is passing on a curve prohibited even when the traffic seems light?
Show answer
Answer C: You cannot see far enough around it to know the lane is clear
A pass is only as safe as the distance you can see, and a curve hides the very lane the maneuver uses.
-
2. 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.
-
3. A helmet falls from the seat onto a hard floor but shows no cracks. What should the owner do?
Show answer
Answer C: Replace it or have it checked, because the liner can be crushed inside
The foam liner can be compressed with no outside sign, and crushed foam will not absorb a second impact, so a helmet that has taken a hard knock should be replaced.
-
4. The car ahead drifts across the lane line and back again several times. What should you do?
Show answer
Answer C: Assume that the driver is distracted or impaired, and keep well back
Drifting is a classic sign of a distracted, drowsy or impaired driver, and distance is your protection from all three.
-
5. A rider needs to stop quickly while leaned over in a curve. What is the best technique?
Show answer
Answer D: Bring the motorcycle upright where possible, then brake firmly with both brakes
An upright tire has more traction available for braking, so lean angle should be reduced as brake pressure is increased.
-
6. When should most of your braking for a turn be finished?
Show answer
Answer B: Before you begin to turn the wheel
Slow to the right speed before the turn begins; braking hard while turning uses up the grip the tires need for steering.
-
7. A yellow diamond shows a horse with a rider. Besides slowing down, what else should a driver do?
Show answer
Answer C: Avoid using the horn or revving the engine
The equestrian crossing sign warns of horses on or across the road, and a sudden noise can startle an animal into the traffic lane.
-
8. You have a green light and an ambulance with lights and siren enters the intersection against its red. What should you do?
Show answer
Answer B: Stop and let the ambulance go through
An emergency vehicle answering a call may cross against a red, and every other driver yields to it whatever their own signal shows.
-
9. 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.
-
10. You must cross tracks or pavement seams that run in nearly the same direction as your path of travel. What should you do?
Show answer
Answer C: Move far enough away to cross at an angle of at least 45 degrees, then turn sharply across
A shallow crossing lets the groove catch and steer the front wheel, so the rider sets up to cross at 45 degrees or more and makes one deliberate turn across it.
-
11. You are approaching an intersection in a line of traffic. What can you do to be more visible to a driver waiting to pull out?
Show answer
Answer D: Move to a lane position where you are not hidden behind the vehicle ahead
A motorcycle tucked directly behind a larger vehicle is invisible to a waiting driver until the moment it appears, so the rider moves to where the headlight can be seen.
-
12. When may a passenger get off the motorcycle?
Show answer
Answer D: Only after the rider has stopped, braced the machine and said so
A passenger climbing off before the rider is ready removes weight from the back of a machine the rider is still holding upright, which can drop it.
-
13. A face shield keeps fogging up in cool, damp weather. What helps?
Show answer
Answer A: Cracking the shield open slightly, or using an anti fog shield
Fog forms when warm breath meets a cold shield, so moving a little air behind the shield or using an anti fog design is the safe fix.
-
14. You have driven at 70 mph for an hour and then exit onto a town street. What is the common risk?
Show answer
Answer B: Your sense of speed adapts, so 35 mph feels slow and you drive too fast
After a long stretch at high speed the brain adapts, so town speeds feel unnaturally slow; check the speedometer instead of trusting the feeling.
-
15. A driver on a hands free call looks straight at a red light and drives through it. What best explains this?
Show answer
Answer B: The eyes saw it but the brain did not process it
Attention, not eyesight, decides what a driver actually sees, and a loaded mind can leave a driver looking straight at a hazard without registering it.
-
16. What does the thick foam liner inside a certified helmet actually do in a crash?
Show answer
Answer C: It crushes so the head slows down over a longer time and distance
The crushable liner is the part that absorbs energy, letting the head decelerate gradually instead of stopping instantly against a hard surface.
-
17. A crossing guard steps into the roadway ahead of this sign with one hand raised. What must the driver do?
Show answer
Answer B: Stop and stay stopped until the guard waves traffic on
An adult guard is controlling traffic at that crossing, so the instruction given by that person governs and the driver waits to be released.
-
18. You have a green arrow to turn left. What still applies?
Show answer
Answer D: You must yield to any pedestrian or vehicle still inside the intersection
A green arrow protects your turn from conflicting traffic, but you must still let anyone already in the intersection get clear before you move.
-
19. Where should the weight of a load sit in relation to the rear axle?
Show answer
Answer A: Over the rear axle or in front of it
Weight placed behind the rear axle acts as a lever against the steering and can make the motorcycle wobble and handle and brake poorly.
-
20. A driver waiting to turn left appears to be looking straight at you. What should you assume?
Show answer
Answer C: That the driver may still not have seen you, and may turn across your path
Drivers look toward motorcycles without registering them, so eye contact is not evidence that the rider has been seen and no plan should depend on it.
