Which statement best describes ground rules and rules book precedence in effect during a game?

• A. Ground rules always override rules in the book.
• B. Ground rules do not supersede a rules book rule and become in force only when both A and B occur.
• C. Only rules book rules apply and ground rules are not binding.
• D. Ground rules can be used only if both coaches agree and they must align with the book.

Answer: (B)

Ground rules describe local field conditions and are used to handle park-specific situations, but they do not override or supersede any rule in the official rules book. They can be in effect for a game only if they have been agreed upon and published for that game, and they must align with the NFHS rules. If a ground rule conflicts with a rule in the book, the book rule takes precedence. This is why the best description is that ground rules do not supersede a rules book rule and become in force only when they are in line with the book and have been agreed upon for that game.
