When does the game clock start if a snap is being used?

The game clock begins to run after the ball is legally snapped. This is in accordance with NFHS football rules that dictate the timing of the game. Understanding this rule is crucial because it impacts gameplay strategies, such as when to execute a play and how to manage the clock effectively during critical moments in the game.

The other options may seem plausible but do not align with the established rules regarding timing. For example, the referee's signal to start the clock may seem like a logical starting point, but the actual game clock timing is tied directly to the act of the snap. Similarly, the timing does not commence at the end of the previous play, as that would lead to confusion and inconsistent game flow. When the ball is placed for the snap is also inaccurate, as this does not initiate the timing; the timing mechanism is only engaged once the snap occurs. Thus, the correct focus is on the moment the ball is snapped, which is the definitive trigger for starting the game clock.
