This document outlines various hand signals used by officials in basketball games to communicate scoring, timeouts, substitutions, violations, fouls, number of players, and other key information during gameplay. The signals provide a visual method for referees to notify coaches, players, and spectators about events, penalties, and the status of the game clock without interrupting play with verbal announcements.
