- There is no danger provided that the tyre pressure has been reduced to take account of weather conditions.
- There is no danger provided that the tyre pressure has been increased to take account of weather conditions.
Explanation
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.

在湿滑路面上高速驾驶的危险是什么？
- “水滑”或在路面上滑行的危险。
- 轮胎压力可能会自动增加的危险。
- 只要根据天气情况降低轮胎压力，就没有危险。
- 只要根据天气条件增加了轮胎压力，就没有危险。
在大雨或路面积水时，司机应降低车速。这有助于避免“水上滑行”，因为这种现象会减少轮胎与路面的抓地力，从而影响转向和制动。因此，司机在下雨时及雨后应减速，并与前车保持更大的距离。
