What is a recommended safety measure for bicyclists on the road?

Using hand signals is a recommended safety measure for bicyclists on the road because it effectively communicates the cyclist's intentions to drivers and other road users. When cyclists signal their upcoming turns or lane changes, they help to ensure that surrounding vehicles can react appropriately, reducing the risk of accidents. Hand signals are universally recognized and provide a clear visual cue that enhances safety for everyone on the road.

Riding without brakes, wearing dark clothing, and riding in the center of the lane do not promote safety. Bicyclists need to be visible, especially in low-light conditions, and should always have functional brakes for safe maneuvering.
