During which conditions is it prohibited to display visual distress signals?

Displaying visual distress signals is prohibited while on the water unless help is needed because these signals are intended to communicate an emergency situation to other boaters or rescue personnel. Using them without an emergency can cause confusion and may divert resources away from actual emergencies. This rule helps maintain clear communication on the water, ensuring that when a signal is shown, it is recognized as a genuine indicator of distress that requires assistance.

In contrast, displaying signals in calm waters, at night, or during bad weather without an emergency can mislead other boaters and emergency responders, potentially exacerbating situations where actual assistance is required. Therefore, the emphasis on only displaying distress signals when necessary helps to ensure that they retain their significance and effectiveness when truly needed.
