How should cyclists signal their turns?

Cyclists should use hand signals to indicate their turns because these signals are universally recognized and provide clear communication to other road users about their intended actions. Hand signals allow cyclists to keep both hands on the handlebars while signaling their intentions, creating safer conditions for everyone on the road.

Using hand signals is critical for enhancing visibility and ensuring that motorists and other cyclists can anticipate the rider's movements. Proper hand signaling can prevent accidents and misunderstandings among all road users, making it an essential aspect of cycling safety.

Other methods, like shouting, may not effectively convey intentions, especially over distance or amid traffic noise. Pointing the bike or using light signals, while they could convey messages in some scenarios, do not provide the clarity and consistency that hand signals offer within a cycling community.
