What signal indicates that a Jammer has officially been designated as Lead Jammer?

The correct signal indicating that a Jammer has been officially designated as Lead Jammer is the sound of two quick whistles in succession. This signal is a crucial part of the game's rules, as it allows everyone involved—players, officials, and spectators—to recognize who has earned the Lead Jammer status during a jam.

When a Jammer is designated as Lead, they gain the strategic advantage of being able to call off the jam by tapping their hips, which can be crucial for points and game strategy. The two quick whistles serve as an immediate audible signal, distinct from other game sounds and also different from other signals that might indicate game play changes.

In contrast, other signals, like a single long whistle or continuous whistle, do not specifically denote Lead Jammer designation and may be used for other purposes. The clarity and promptness of the two quick whistles are essential for maintaining the smooth flow of gameplay and ensuring that all players and officials are on the same page regarding who has Lead status.
