What is the correct hand signal for stopping?

The correct hand signal for stopping is to extend the arm downward. This signal indicates to drivers behind you that you are coming to a stop, allowing them to react accordingly. Extending the arm downward clearly communicates your intention to stop, as it is easily recognizable and widely accepted among road users, both drivers and cyclists.

It's important to note that proper hand signaling is critical for maintaining safety on the road. Signals should be clear and visible to others, so using a downward arm position helps ensure that others can see your intention to stop, even when visibility may be compromised by factors like distance or traffic conditions. This hand signal is part of the broader set of signaling practices that help ensure safe and effective communication among all road users.
