I was trying to find a NFHS reference to a required procedure of sounding a horn to signal for substitutions. I didn't spend to much time looking, so I might have missed something, but I was surprised that the one and only reference I found was in the NFHS Instructions To Scorers. I could find no other reference in the rulebook or casebook. I was also surprised that it is a negative reference, that is, "should not signal". I would have thought that the NFHS would have a procedure as to when to properly signal for a substitution. I'm sure that I have overlooked something in my haste to quickly come up with an answer.
