Correct answer: C. Engage a lower gear early and use gentle braking applications to keep the speed down.
In snow or ice, a vehicle takes longer to stop. Before starting a steep descent in a large vehicle, the driver should reduce speed and select a lower gear, brake gently and only when needed. If the vehicle is fitted with a manually selectable retarder, engage it before starting the descent.
