Volleyball Rules -- Errors and faults

A player is not in the correct position at the moment of serve, or serves out of turn.

The area "6" player must be behind area "3" player, to the left of area "1" player and to the right of area "5". The area "5" player must be behind the area "4" player and to the left of the area "6" player. Symmetric rules must be respected by the front-row players (those in areas "2", "3" and "4").

When serving, a player steps on the court or the end line before making contact with the ball.
