What does it mean when the lights on the hub are green?

When the lights on the hub are green, it indicates that everyone is allowed on the field. This status signifies that the field is in a safe condition for team members, volunteers, and other authorized personnel to enter. In the context of competitions, this is crucial for ensuring smooth operations during events, as it provides clear communication about who can be present in the competition area at any given time.

In contrast, when the lights are not green, access may be restricted to only specific individuals, such as team managers or event staff, for safety and operational reasons. Therefore, understanding the meaning of the light signals helps all participants to adhere to the rules and maintain a safe environment during the event.
