What can be the effect of aquaplaning?

The selected combination of answers, which includes reduced ability to steer the vehicle and reduced vehicle braking capability, is correct because both effects are critical in understanding aquaplaning. When a vehicle experiences aquaplaning, it occurs when water on the road prevents the tyres from maintaining contact with the surface. This loss of contact results in a significant reduction in steering control and braking efficiency, which can lead to dangerous situations.

According to German traffic regulations, drivers are required to maintain a safe speed and distance from other vehicles, especially in wet conditions, to mitigate the risks associated with aquaplaning. Recognizing the impact of these factors is essential for safe driving and adherence to road safety laws in Germany. The option regarding increased tyre static friction does not fit here, as aquaplaning actually reduces the friction between the tyre and the road, making it crucial to understand the implications of the correct choices.
