What notation indicates when a Libero serves prior to the court switch?

The notation indicating when a Libero serves prior to the court switch is represented by triangles placed on both sides of the scoresheet. This is essential for tracking the participation of the Libero, who has specific rules regarding serving and positional play. The double triangles provide clear visual cues to officials and team members that the Libero is eligible to serve for that rotation, especially when the team transitions from one side of the court to the other. This helps to maintain accurate records regarding player rotations and serving responsibilities throughout the match.

Other options do not accurately reflect the necessary notation for the Libero's service. For instance, a single triangle symbol only indicates a serve or substitution but does not provide the clarity required for tracking the Libero’s unique role effectively. Similarly, a circle beside the exit score does not pertain to the Libero's serving status, and asserting that no special notation is required would undermine the need for clear communication among players and officials regarding the Libero's participation during serving situations.
