Which hand signal indicates that a bicycle is stopping or slowing?

The hand signal that indicates a bicycle is stopping or slowing is the left arm positioned at a right angle, also known as the "Left Arm at a Right Angle." This signal is universally recognized among cyclists and motorists as a clear indication that the cyclist is about to reduce speed or come to a stop. When a cyclist extends their left arm upward at a right angle, it effectively communicates this intention to others on the road.

Using correct hand signals is crucial for ensuring safety on the road, allowing drivers and other cyclists to anticipate the biker's actions. This practice of signaling engages all road users and contributes to safer navigation, establishing a clear system of communication. Therefore, understanding proper hand signals is essential for cyclists when sharing the road with other vehicles.
