Penalty Signal

A penalty signal is a prearranged, standardized gesture — made with the hands and arms, or with a flag — that a match official uses to communicate a decision to everyone on and around the field of play. Because officials cannot always be heard over crowd noise or across a large playing area, a visible signal lets players, coaches, scorers, and spectators instantly understand that a rule has been broken and what happens next. The same idea recurs across most refereed and umpired sports, even though the specific gestures differ from one game to another.

Signals typically carry several layers of meaning at once: that an infringement has occurred, what type of offence it was, which team is penalized or awarded the restart, and the sanction that follows. Some sports rely mainly on hand and arm gestures from a central referee, others add flags raised or thrown by assistants or line officials, and many pair the signal with a whistle beforehand and a verbal or announced explanation afterward. To keep calls consistent between different officials and understandable regardless of language, these gestures are usually codified in an official signal chart that every referee learns.
