What is the term used when opposing players commit a rule violation at the same time?

The correct term for when opposing players commit a rule violation at the same time is a double fault. In volleyball, a double fault typically refers to a situation in which both teams have committed errors simultaneously, resulting in a replay of the point rather than awarding it to one side. This term captures the essence of simultaneous infractions and reflects the idea that both teams are equally at fault for the violation occurring at that moment.

In the context of volleyball rules, understanding this term is essential because it impacts the flow of the game and how points are awarded or replayed. Recognizing that the infractions must occur concurrently plays a crucial role in officiating and in the strategic mindset of players and coaches during the match.
