When a spotter signals for stopping while backing, how should the arms be positioned?

When a spotter signals for stopping while backing, the correct positioning of the arms is crossed into a large X. This specific arm signal is widely recognized in various safety protocols, especially in construction and driving environments, as a clear indication for the operator to halt their movement.

The large X formed by the crossed arms is visually distinctive, making it easily noticeable for the operator, even from a distance. This signal effectively communicates urgency, prompting the operator to stop immediately, thus enhancing safety for both the operator and those in proximity. In scenarios where the operator might be focused on their immediate surroundings, having a clear and recognizable signal helps prevent misunderstandings that could lead to accidents or injury.

Other signals, such as arms out to the side or hands raised above the head, are used for different commands, like indicating directions or indicating to move, which could create confusion if used instead of the designated stop signal. The positioning of the arms pointing towards the ground does not convey any specific action in the context of stopping and lacks clarity in communicating the urgent need to halt.
