For answer  A 

The automatic braking system has no influence on preventing the phenomenon of aquaplaning. Aquaplaning is caused by the loss of contact between the tires and the carriageway due to a layer of water. In this case, braking systems, including automatic ones, do not help, because the problem is related to grip, not to braking capability.

For answer  B 

Aquaplaning can be avoided when the motorcycle’s tires are in good condition, with sufficient tread to disperse the water from the carriageway, and when the riding speed is reduced. The grip of the tires depends on their ability to evacuate the water, and reduced speed minimizes the risk that the layer of water prevents contact between the tires and the road. If these conditions are met, the motorcyclist can maintain control of the vehicle, preventing skidding or loss of balance, which are major risks in the case of aquaplaning. More about the ABS system can be found here - ABS System

The most important risks in the case of aquaplaning with a motorcycle:

• Loss of grip, which can lead to the lateral slipping of the front or rear wheel.
• Loss of the motorcycle’s balance, which can cause falls or collisions.
• Increase of the stopping distance, which increases the risk of an accident, especially in heavy traffic conditions.

For answer  C 

Overloading the motorcycle does not prevent aquaplaning. Even if a heavier motorcycle might seem more stable in certain situations, it remains vulnerable to losing grip on a water-covered carriageway. In addition, overloading the motorcycle (loading it beyond the maximum authorized total mass (MTMA)) is prohibited and can generate other problems related to road safety.

The correct answer is: B
