Which signal should be used to indicate stopping while riding a motorcycle?

The appropriate signal to indicate stopping while riding a motorcycle is pointing downward. This signal is clear and universally recognized, prompting other road users to understand that you are about to stop. By pointing downward, you convey a direct message of your intention without creating confusion.

This method of signaling is particularly effective because it allows you to keep your other hand on the throttle or brake, maintaining better control of the motorcycle, especially in traffic situations where swift communication is essential. It is important for the signal to be distinct and noticeable to ensure that drivers and pedestrians are aware of your actions, contributing to overall road safety.

Other signals, such as raising a hand above the head or striking the left arm, are generally associated with different actions like turning or stopping in non-motorcycle contexts but may not effectively communicate stopping intentions to those around you.
