What is a "foot fault" in volleyball?

A "foot fault" in volleyball specifically refers to the situation where a player steps on or over the service line while executing a serve. This is a crucial point in the game, as serving is one of the key moments that can directly influence the score. The rules require that the server must remain behind the service line, and any movement over the line during the serve constitutes a fault.

This rule exists to ensure fairness and maintain the integrity of the serve, as stepping over the line could give the server an unfair advantage in terms of distance to the net and the angle of the serve. Understanding this violation helps players and teams adhere to the proper techniques while serving and reinforces the importance of following the established rules of the game.
