1. How should the rider's body be positioned in a slow, tight turn?
Correct answer: Held upright while only the motorcycle leans
Slow tight turns call for counterbalancing: let the machine lean while you stay upright.

2. What is the purpose of rolling on the throttle in a turn?
Correct answer: To hold or slightly raise your speed, which helps steady the motorcycle
Maintaining or gently increasing speed through the corner stabilizes the motorcycle, which is why the last step is to roll on.

3. As you look through a turn, what does the manual say to do with your eyes?
Correct answer: Keep them level with the horizon while looking where you intend to go
The manual asks riders to look through the corner toward their intended path and to keep their eyes level with the horizon.

4. What four steps does the manual give for taking a turn effectively?
Correct answer: Slow, look, press, roll
The four overlapping steps are slowing before the turn, looking through it, pressing the handgrip to lean, and rolling on the throttle.

5. How does lean angle relate to speed and sharpness of a turn?
Correct answer: The faster the turn or the tighter it is, the more lean is needed
The manual states that a higher speed or a sharper corner calls for a greater lean angle.

6. A rider enters a corner too fast for his skill. What two outcomes does the manual describe?
Correct answer: He drifts into another lane or off the road, or he panics and brakes so hard that he skids
Taking a curve too fast leaves riders unable to hold their line — crossing into other traffic or leaving the road — or overreacting with heavy braking that ends in a skid.

7. When turning a three-track motorcycle, what does the manual say to do with the brakes?
Correct answer: Slow enough to ride the turn safely, then let the brakes off before you enter it
The three-wheel routine is to roll off the throttle, brake down to a safe speed, release the brakes before the turn, then roll on gently for stability.

8. The manual sums up leaning with a short rule. Which statement matches it?
Correct answer: Press the left grip, the motorcycle leans left, and you go left
Pressing a handgrip leans the motorcycle to that side and steers it that way: press left, lean left, go left.

9. Why can a conventional three-wheel motorcycle not be countersteered?
Correct answer: It cannot lean
Countersteering depends on leaning, and a conventional three-wheeler stays flat, so the rider simply points the front wheel where the machine should go.

10. The manual warns that every curve is different. Which of these is one of the shapes it tells riders to watch for?
Correct answer: A curve that tightens as it goes
Riders are told to notice whether a curve holds a constant radius, opens out, tightens up, or strings several bends together.

11. On a motorcycle with a sidecar, when is the sidecar wheel most likely to lift?
Correct answer: During a right turn, above all when the sidecar carries little or no load
Turning right shifts the center of gravity sideways and tends to raise the sidecar wheel, and the effect is stronger when the sidecar carries little or no weight.

12. Where does the manual suggest positioning yourself before entering a curve?
Correct answer: In the middle of your lane, holding that position until you are out of the curve
Moving to the center of the lane before a curve and staying there until the exit lets you pick up approaching traffic early and leaves room to react to crowding or debris.
