5. No player shall use words or signals that disconcert opponents when they are preparing to put the ball in play. No player may call defensive signals that simulate the sound or cadence of, or otherwise interfere with, offensive starting signals.
Approved Ruling 7-1-5 V 3/2 @ B-45. Team A is in formation and the snap is imminent. Team A QB is in shotgun formation and is using a clap as a starting signal.
