1. If you can’t avoid a dangerously slippery surface, you should:
Speed up and lean the motorcycle.
Speed up and keep the motorcycle upright.
Slow down and lean the motorcycle.
Slow down and keep the motorcycle upright. ✓
Answer: D. Slow down and keep the motorcycle upright.
You should slow down and keep the motorcycle upright. The manual's slippery-surface section says to reduce speed before you reach a slippery surface to lessen the chance of a skid. It also calls for smooth, gradual control because a sudden change in speed or direction can cause a skid. When stopping, the manual says to straighten the handlebars in the last few feet to maintain balance and stay upright. Together, slowing down and staying upright is the safe response if you cannot avoid the slippery area.
When it starts to rain, the best move is to ride in the tire tracks left by cars. The manual lists the center of a lane as a spot that can be hazardous when wet, and it says plainly that when rain begins you should ride in the tire tracks left by vehicles. It adds that the left tire track is often the best position, depending on traffic and road conditions. The same section tells you to slow down before slippery surfaces and to avoid sudden moves, so your job in rain is to pick the less slippery part of the lane and keep your inputs smooth.
Alternate between your headlight's low and high beam settings.
Answer: B. Use your low beam headlight.
When riding in rain or fog, use your low beam headlight. The manual says to use low beam at night and in fog. These passages do not give a separate rain instruction, but the fog guidance points to low beam in reduced visibility. Low beam is the setting the manual ties to riding in fog, so it fits the bank answer. The passages do not say to use high beam in fog; the high-beam advice is about using as much light as you can when you are not following or meeting a car.
Is only a concern if the front tire is also skidding.
Answer: B. Eliminates your ability to change direction.
A skidding rear tire eliminates your ability to change direction. The manual explains that too much rear brake pressure locks the rear wheel, and as soon as that wheel locks, you lose the ability to steer the bike. You only get control back by releasing the brake. It also warns that if the rear wheel is out of line with the front when you let go, the bike can snap upright and throw you off, so a rear-wheel skid is a serious situation that has to be handled, not ignored.
5. What should a motorcyclist do to prevent possible injury when riding on a slippery surface?
Increase their speed.
Reduce their speed. ✓
Make sudden moves.
Ride on the shoulder.
Answer: B. Reduce their speed.
To prevent possible injury on a slippery surface, the motorcyclist should reduce their speed. The handbook says to slow down before reaching a slippery surface to lessen the chance of skidding. It also notes that a motorcycle needs more distance to stop and that slowing down is especially important before entering wet curves. The same passage warns that sudden changes in speed or direction can cause a skid, so the rider should stay smooth. Reducing speed fits the manual's direct guidance for slippery surfaces.
Easier than riding during the day because you can more easily see the lights of other vehicles.
More difficult than riding during the day because it is harder to see. ✓
Not allowed on highways.
Less distracting than riding during the day.
Answer: B. More difficult than riding during the day because it is harder to see.
Riding at night is more difficult than riding during the day because it is harder to see. The manual says plainly that at night it is harder for you to see and be seen, and that other drivers find it hard to pick your headlight or taillight out of the surrounding car lights. It also notes that distances are harder to judge in the dark because your eyes depend on shadows and light contrast. That is why it tells riders to slow down, keep a bigger following gap, and use the headlights of the car ahead to help read the road.
Pull off to the side of the road until the rain stops.
Ride in the tire tracks left by cars. ✓
Increase your speed.
Answer: C. Ride in the tire tracks left by cars.
When it is raining, the best choice is to ride in the tire tracks left by cars. The manual explains that the middle of a lane can be a bad place to be once rain starts, so you should put your wheels where other vehicles have already driven. Those tracks give you a better surface than the slick center. It adds that the left track is often the best spot, depending on traffic and road conditions, and reminds you to slow down and stay smooth on any wet surface. So following car tracks is the riding position the manual recommends, not stopping or speeding up.
9. When riding at night, you should do all of the following, except:
Reduce your speed.
Increase your following distance.
Decrease your following distance. ✓
Use your high beam light, if possible.
Answer: C. Decrease your following distance.
The one thing you should not do at night is decrease your following distance — you want more room, not less. The manual says following too closely is a common factor in motorcycle crashes, and that a rider normally needs at least a two-second gap behind a vehicle. At night it also tells you to slow down enough to stop within the distance your headlight shows you, and to use your high beam whenever you are not following or meeting a car. All of that points to keeping a bigger cushion after dark, so cutting your following distance goes against the manual's advice rather than being part of it.
10. Which of the following surfaces does not provide poor traction?
Wet pavement
Dry pavement ✓
Lane markings
Snow
Answer: B. Dry pavement
Dry pavement is the surface that does not provide poor traction. The manual says a motorcycle handles better on surfaces that allow good traction. It then names surfaces with poor traction: wet pavement, especially just after rain starts and before oil washes to the side, plus gravel roads and places where sand and gravel collect. Dry pavement is not among those poor-traction surfaces. That makes it the choice that does not provide poor traction, since the passage treats wet and loose-material surfaces as the problem and dry pavement as the contrast.
