What should a driver do when driving in heavy rain?
- Increase speed so that the vehicle will glide over any standing water.
- Maintain normal speeds as on a dry road.
- Correct answerBe aware that the vehicle may slide or 'aquaplane'.
- Weave the vehicle slightly in order to improve tyre grip.
Explanation
On a wet road, a film of water can build up between the tyres and the road surface. This is called aquaplaning and it 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.

司机在大雨中驾驶时应该怎么做？
- 提高速度，使车辆滑过积水。
- 在干燥路面上保持正常速度。
- 请注意，车辆可能会打滑或“水上滑行”。
- 轻微摆动车辆以提高轮胎抓地力。
在湿滑的道路上，轮胎和路面之间可能会形成一层水膜。这被称为水滑现象，会降低轮胎在路面上的抓地力，从而影响转向和制动。因此，司机在下雨时和雨后应减速行驶，并与前车保持更大的距离。
