When a server steps past the serving line in volleyball, it is called a foot fault. A foot fault occurs when the server's foot completely crosses the back boundary line of the service area during the serving motion. This is considered an error in volleyball as the server is required to remain behind the serving line until after the ball is contacted for the serve.
To avoid foot faults, players should make sure to start their serving motion with both feet behind the serving line. By maintaining proper positioning, players can ensure that they do not commit foot faults during their serves. It is important for servers to be aware of their foot placement to avoid penalties and maintain the integrity of the game.
