Which signal corresponds to Send Rider?

• A. Arm straight above head.
• B. Thumbs Up.
• C. Patting of the head.
• D. Put arms in X to stop sending riders.

Answer: (B)

The signal for Send Rider uses a thumbs up. This gesture clearly communicates approval and permission to proceed, which is exactly what you need when you’re ready to dispatch a rider. It’s quick to see, easy to understand from a distance, and universally understood as “go ahead.”

The other gestures don’t fit as well. An arm straight above the head can look like signaling for attention or a different instruction, not specifically permission to send. Patting the head is ambiguous and easy to misread in a fast-paced setting. Crossing the arms in an X clearly means stop or don’t proceed, which is the opposite of sending a rider.
