Show answer & explanation
Correct answer: Steering and braking will be less effective..
When driving on a road where there is a lot of surface water; a film of water can build up between the tyres and the road surface. When this occurs it is called aquaplaning; it reduces the grip of the tyres on the road and can result in the total loss of control over the vehicles steering and braking.
