How many yards is the penalty for an illegal procedure foul?

The penalty for an illegal procedure foul is indeed 5 yards. This infraction usually occurs when the offense violates the rules concerning the manner in which they set up or begin a play, such as not being set for a full second before the snap or having players move in a way that creates an unfair advantage. The 5-yard penalty is consistent across many similar procedural violations, reflecting the NFHS's commitment to maintaining fair play while allowing the game to flow smoothly. This enforcement helps to discourage unnecessary disruptions that can be caused by a team's failure to adhere to the basic setup requirements for a play.
