1. Your front wheel drops off the edge of the pavement onto a lower shoulder. What is the safest way back?
Show answer
Answer D: Ride straight, slow down, then turn back sharply enough to cross the edge
Trying to climb a raised pavement edge at a shallow angle lets the tire slide along it, so the rider settles first and then crosses the edge at a sharp angle.
-
2. Heavy rain has left standing water on the road where this sign is posted. What does the law expect of the driver?
Show answer
Answer C: Driving below the posted figure, at a speed that suits the conditions
Drivers must adapt to conditions, so in rain, fog, snow or dense traffic the safe speed falls below the posted maximum and keeping to that maximum can itself be an offense.
-
3. A flashing red lamp is mounted above a stop sign at a rural intersection. What does it add?
Show answer
Answer C: Emphasis, while the required stop stays the same
A stop beacon makes an easily missed stop sign more visible, but it neither adds to nor takes away from the obligation the sign already imposes.
-
4. What is the first thing to do once your disabled vehicle is stopped on the shoulder?
Show answer
Answer A: Switch on the hazard warning lights so other drivers can see the vehicle
Hazard lights are the fastest way to make a stopped vehicle visible, and everything else can follow once traffic has been warned.
-
5. You are moving at walking pace through a crowded parking area. Which combination gives the steadiest control?
Show answer
Answer B: Steady throttle, the clutch held in the friction zone and light rear brake
Slipping the clutch in the friction zone against a steady throttle and a light drag of rear brake keeps power smooth and the machine stable below walking speed.
-
6. Two drivers each have three drinks, one over three hours and one in half an hour. What is the difference?
Show answer
Answer C: The fast drinker reaches a higher peak level
The liver removes alcohol at a steady rate, so drinking faster than the body can clear it pushes the blood alcohol level much higher.
-
7. You must park on soft ground or on asphalt softened by heat. What should you do about the sidestand?
Show answer
Answer A: Put a flat, firm object under the stand to spread the load
A sidestand concentrates the weight of the machine onto a very small area, and on soft ground it sinks in until the motorcycle falls over.
-
8. Why is smooth, early braking better than hard, late braking?
Show answer
Answer D: It keeps you in control and gives the driver behind more warning
Braking early and gently keeps the tires well within their grip and gives following drivers time to react to your brake lights.
-
9. Why must a rider pay attention to the turn signal after completing a turn or lane change?
Show answer
Answer A: Many motorcycle signals do not cancel themselves and can mislead other drivers
A signal left flashing tells other drivers the rider is about to turn again, and a driver may pull out in front of the motorcycle because of it.
-
10. On a highway with mileage-based exit numbering, you have just passed exit 42 and are looking for exit 55. About how far is it?
Show answer
Answer B: Thirteen miles
With mileage-based numbering each exit takes the number of the nearest milepost, so subtracting one exit number from another gives the distance in miles.
-
11. You must slow suddenly on a highway and a vehicle is following close behind you. What helps prevent a rear-end collision?
Show answer
Answer D: Tapping the brake pedal early so your brake lights flash a warning
Early brake light flashes give the driver behind more time to react, and slowing gradually instead of suddenly reduces the chance of being struck.
-
12. How does the distance needed to stop change when a rider doubles speed?
Show answer
Answer D: It grows to roughly four times the original distance
Braking distance rises with the square of speed, so twice the speed needs roughly four times the distance in which to stop.
-
13. You park at the roadside on a hill, facing downhill. What keeps the motorcycle from rolling away?
Show answer
Answer D: Leaving it in first gear with the front wheel turned toward the curb
A motorcycle has no parking brake, so the transmission left in gear stops the wheel turning and the front wheel turned into the curb blocks any roll.
-
14. You are turning right from a one-way street onto a two-way street. Where should the turn end?
Show answer
Answer A: In the lane nearest the right curb of the street you are entering
A right turn starts and finishes as close to the right as practical, so you leave the one-way street from the right lane and arrive in the lane nearest the right curb.
-
15. A passenger is getting on at the roadside. Which side should they use if the exhaust and the sidestand allow it?
Show answer
Answer B: The side away from moving traffic, clear of the hot exhaust
Getting on and off away from passing vehicles keeps the passenger out of traffic, and the side chosen must also keep their leg clear of the hot exhaust.
-
16. At 45 mph you look at a navigation screen for four seconds. Roughly how far do you travel unseeing?
Show answer
Answer D: About 260 feet
At 45 mph you cover roughly 66 feet a second, so four seconds on a screen is around 260 feet of road that you never looked at.
-
17. This sign comes into view ahead of a driver who has already started along a ramp. What should the driver do?
Show answer
Answer B: Pull clear where it is safe, then turn around and leave the ramp traveling properly
The driver is traveling against the legal flow, so the safest response is to stop clear of the lanes, turn the vehicle around and get off the ramp before meeting traffic head on.
-
18. It is very hot and a rider is tempted to take off the riding jacket. Why can that make the heat worse?
Show answer
Answer C: A bare arm in hot moving air loses fluid fast and burns in the sun
In hot, dry air a covering layer slows the evaporation of sweat and blocks the sun, so ventilated gear can keep a rider cooler and better hydrated than bare skin.
-
19. You are in the acceleration lane and the gap you were aiming for is now beside you. What is the best adjustment?
Show answer
Answer A: Change your speed a little to line up with a gap, then merge smoothly
The acceleration lane is for matching both the speed and the position of a gap, and small speed adjustments are what line the two up.
-
20. A wide solid white line separates the through lanes from an exit lane. What does it tell drivers?
Show answer
Answer B: The choice of lane should already have been made
A channelizing line marks where the paths separate and crossing it is discouraged or prohibited, so the lane change has to happen upstream.
-
21. Why do safety agencies put head protection first among riding gear?
Show answer
Answer A: Because head injuries are the leading cause of death in motorcycle crashes
Head injury is the most common cause of death in motorcycle crashes, which is why a certified helmet is the single most important piece of gear.
-
22. How is the rear brake applied on a standard motorcycle?
Show answer
Answer D: By pressing down a pedal with the right foot
The rear brake pedal is in front of the right footrest and should be pressed down smoothly rather than stamped on.
-
23. Which facility does this sign direct a traveler toward?
Show answer
Answer B: A hospital offering emergency care
This is the standard marker for medical care, used to lead a traveler to a hospital where emergency treatment is available.
-
24. Which feature suggests that a helmet is an uncertified novelty helmet?
Show answer
Answer D: A shell less than one inch thick with no firm foam liner
Novelty helmets are typically thin and very light because they lack the stiff energy absorbing liner that a certified helmet uses to manage an impact.
-
25. What happens to your field of vision as your speed increases?
Show answer
Answer C: It narrows, so you notice less at the sides of the road
The faster you travel, the more your useful field of view narrows toward the center, so a hazard coming from the side is seen late or missed altogether.
