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

When it comes to communication between a driver and a helper, the most important hand signal to agree upon is the signal for stopping. This is vital because stopping ensures that both the driver and helper can operate safely, especially in situations where visibility may be limited or when the driver needs to halt their vehicle to avoid a potential hazard. A clear and recognized signal for stopping can prevent accidents and ensure that both parties are synchronized in their actions, particularly in high-pressure or busy environments. Without a reliable stop signal, the risk of miscommunication increases, potentially leading to dangerous situations.

While signals for turning left or right and for going ahead are also important in directing movement, ensuring that the vehicle is brought to a stop effectively is foundational for safety and coordination.
