1. A driver is passing you. Where should you ride while it happens?
Correct answer: Hold the middle of your own lane
Holding the center portion keeps distance between you and the passing vehicle, guarding against a sideswipe, extended mirrors, thrown objects, and wind blast.

2. How do you check your following distance using the counting method in the manual?
Correct answer: Choose a marker ahead, and start counting when the back of the vehicle ahead reaches it — arriving before the count ends means you are too close
Pick a pavement mark or a lamppost, start counting when the back of the vehicle ahead passes it, and if you get there before the count ends you need to drop back.

3. Where does the manual warn that heavy buildups of oil and grease are most likely?
Correct answer: At busy intersections and tollbooths
Oil and grease pile up where vehicles idle and stop repeatedly — busy intersections and tollbooths — and riders are told to keep off those patches.

4. What collects in the middle third of a traffic lane, and does that make it unusable?
Correct answer: Debris and oil drippings gather there, but the strip usually still grips well unless the road is wet
Cars drop oil and push debris toward the center, yet the manual says the typical center strip gives adequate traction on a dry road, and you can ride to either side of the grease strip and still be in the center third.

5. How should the rider of a three-wheel motorcycle or a sidecar rig position the vehicle in a lane?
Correct answer: Toward the center, so the dual wheels do not cross the painted lines
The dual track is nearly as wide as a car, so lane position choices shrink; keeping to the center stops the wheels crossing into opposing traffic, and riding too far right risks losing traction off the pavement.

6. Why does the manual discourage riding alongside cars or trucks in neighboring lanes?
Correct answer: Because you may sit in a blind spot, and those vehicles also block your escape route if trouble appears in your own lane
Two risks are named: a driver may change lanes into you without seeing you, and a vehicle beside you takes away the escape path you might need.

7. What does the manual say about lane sharing?
Correct answer: It is usually prohibited, because cars and motorcycles each need a full lane
Both vehicles need a full lane to operate safely, and the manual notes that sharing one is generally not permitted; slipping between rows of cars leaves you exposed to opening doors and sudden turns.

8. Which lane position do many riders treat as their default, and what does the manual say about the rest of the lane?
Correct answer: The left third; no part of the lane, the center included, has to be avoided outright
Many riders default to the left third, the left car tire track, but the manual stresses varying position as conditions change and notes that no portion of the lane must be ruled out.

9. When are drivers most tempted to squeeze past you inside your own lane?
Correct answer: In bumper-to-bumper traffic, when they want by, when you set up for a turn, or when you move toward an exit
The manual lists heavy stop-and-go traffic, a driver who wants to pass, a rider preparing to turn at an intersection, and a rider moving into an exit lane as the moments to guard the center of your lane.

10. In a staggered group formation, where does the second rider ride?
Correct answer: In the right side of the lane, at least one second behind the leader
The leader takes the left of the lane and the second rider holds the right side, staying at least a second back; the third rider returns to the left, two seconds behind the leader.

11. What minimum following distance does the manual call for in normal conditions?
Correct answer: Two seconds
Two seconds is the normal minimum behind another vehicle; in traffic a motorcycle needs as much room to stop as a car does.

12. How many paths of travel does the manual say a single traffic lane offers a motorcycle?
Correct answer: Three
Because a motorcycle is narrow, each lane gives it three usable paths, and the rider should pick the one that suits the situation.
