Driving down a long steep hill on a n Inter-urban road
- Go to a higher gear to complete the gradient quickly.
- Travel in Neutral.
- Brake for a few seconds so as not to drive too fast
- Correct answer: Sow down, change down to a lower gear according to the gradient
Why this is the answer
The correct answer in the official bank: Sow down, change down to a lower gear according to the gradient
On a long descent, change down to a lower gear suited to the gradient, so the engine brakes the vehicle (engine braking) and keeps the speed under control. Frequent or prolonged braking may overheat the brakes and weaken them just when they are needed. Driving in Neutral removes engine braking and impairs control of the vehicle, and a high gear weakens engine braking, so the vehicle accelerates downhill.
