What is the most important hand signal to agree upon with your helper?

Establishing a clear signal for stopping is crucial in any operation that involves a helper, especially in situations where visibility is limited or where vehicle movement can pose risks. A stop signal ensures that both the driver and the helper are on the same page regarding the immediate cessation of motion, which is vital for safety. Recognizing when to stop prevents accidents and allows time to assess the environment, check for obstacles, and ensure that everyone involved is safe before proceeding with any further actions.

While signals for moving forward or turning are also important, they can lead to more complex situations if not executed properly. A stop signal acts as the first point of control in operation, allowing for clear communication and coordination before taking any additional steps. The emphasis on having a universally understood stop signal underscores its role as a fundamental safety practice in any driving or maneuvering scenario.
