Answer: A. downshifting, turning, or starting on hills.
Incorrect gear use can lead to accidents when downshifting, turning, or starting on hills.
Why this is the answer
The handbook says a rough, jerky downshift can lock the rear wheel and cause a skid, and it tells riders not to shift gears while turning. It also explains that starting on a hill with a clutch and gears is harder than starting on level ground, and that releasing the clutch too quickly can stall the engine or lift the front wheel. Those warnings point to downshifting, turning and hill starts as the situations where incorrect gear use can get you into trouble.
Why the other answers are wrong
- B. changing gears on plain roads. — Changing gears on plain roads is not singled out; the handbook's warnings are about rough downshifts and shifting while turning, not ordinary gear changes on flat roads.
- C. riding in heavy traffic. — Riding in heavy traffic is not mentioned in the passages as a gear-use accident situation; the handbook focuses on downshifting, turning and hill starts.
- D. riding with a passenger on two-way roads. — Riding with a passenger on two-way roads is not covered by these passages as a gear-use hazard, so it does not fit the handbook's warnings.
Remember it
Link each risky moment to its fix: gear sorted before the turn, clutch eased on the hill.
