Which statement about driving on uphill and downhill roads is NOT correct?
💡 Hint
Near the top of a slope and on the downhill of a steep slope are places where you must drive slowly (Article 31(1)3 and 4 of the Road Traffic Act). On a downhill, recall what is needed for the engine brake to work, and be suspicious of reasons like 'saving fuel' that trade away safety.
Answer: ④
Explanation
Article 31(1) of the Road Traffic Act designates the area near the top of a slope and the downhill section of a steep slope as places to drive slowly. Coasting downhill in neutral gives no engine brake effect at all, so you rely only on the foot brake and risk losing braking power from overheating (fading, vapor lock). You should therefore stay in a low gear and use the engine brake as well.
