Show answer & explanation

Correct answer: A. Danger of 'aquaplaning' or sliding across the road surface.

The driver should moderate their speed during heavy rain or where water is building up on the road surface. This will help to avoid 'aquaplaning' which has the effect of reducing the grip of the tyres on the road, and this affects the steering and braking. For these reasons the driver should slow down during and after rain and keep a greater distance from the vehicle in front.
