What is the purpose of using hand signals in bright sunlight?

The correct choice highlights the primary reason for using hand signals in bright sunlight: to ensure visibility of your intentions. When riding a motorcycle, it's crucial to communicate effectively with other road users to enhance safety. Bright sunlight can make it difficult for others, including drivers in vehicles and fellow motorcyclists, to see turn signals or brake lights clearly. By using hand signals, a rider can communicate their intended actions, such as turning or stopping, in a way that is more easily observable, thus reducing the risk of accidents. This practice is particularly important in circumstances where electronic signals might be impaired due to glare or lack of visibility.

While looking professional, alerting other riders, and complying with laws may have their own merits, the essence of using hand signals in bright sunlight is fundamentally centered on ensuring that your intentions are clearly visible to others on the road.
