What is the primary reason for using hand signals while riding a motorcycle?

The primary reason for using hand signals while riding a motorcycle is to communicate intentions to other road users. Hand signals provide a clear and effective way for motorcyclists to signal their intentions, such as turning or stopping, to drivers, cyclists, and pedestrians. This non-verbal communication is critical for enhancing safety on the road, as it can help others anticipate a rider's actions and adjust accordingly.

Using hand signals is especially important because motorcycles can often be less visible than larger vehicles, and many riders may not be equipped with the same types of turn signals that are standard on cars. Therefore, hand signals serve as an important tool for ensuring that all road users are aware of a motorcyclist's movements, thereby reducing the risk of accidents.

In contrast, options that involve showing off riding skills or trying to increase speed do not serve a safety purpose and can lead to dangerous situations. Confusing other drivers is counterproductive and could also lead to misunderstandings that might result in accidents.
