Question 8157

When there are patches of ice on the roadway, what is the most advisable and safest way to drive down a long downhill grade?

  1. By reducing speed with the parking brake, especially when going through curves.
  2. In a low gear, to brake as little as possible.
  3. In a high gear, to improve the grip of the drive wheels.
Show answer and explanation

Correct answer: In a low gear, to brake as little as possible.

On a long downhill grade with patches of ice, slow down before you start and use a low gear. The engine holds the car back so you need to brake very little, which is what you want on ice, because any braking can lock the wheels. High gears are useful on level ground and uphill, and using the parking brake in curves can make you skid.
