What indication does a referee give for a penalty call?

In roller derby, when a referee makes a penalty call, it is standard practice to use both visual and auditory signals to ensure that all players, officials, and spectators understand the decision being made. This dual approach encompasses a whistle blow, which serves as an immediate auditory cue that something significant has occurred, along with a hand signal that visually indicates the nature of the penalty.

The hand signal is critical, as it communicates specific information about the infraction, allowing players and coaches to quickly identify what violation has taken place. This combination of a whistle and a hand signal provides clarity and ensures that the game can proceed smoothly with all parties aware of the rules being enforced. This method enhances the overall communication during the match and upholds the integrity of the sport.
