What is the purpose of a Distress Signal?

The purpose of a Distress Signal is to request assistance in emergencies. When a vessel or person is in distress or facing life-threatening situations, sending a distress signal alerts nearby vessels, rescue agencies, and authorities that immediate help is needed. This signal can take various forms, including visual signals like flares, auditory signals such as radio distress calls (like "Mayday"), or other recognized signals that convey urgency. The primary aim is to ensure quick and effective response from others who can provide aid. This critical communication can be vital for survival in situations such as capsizing, grounding, or medical emergencies at sea.

Other options, while relevant to maritime communication, do not accurately represent the specific function of a distress signal. For instance, providing weather updates, signaling for the arrival of vessels, or informing about routine traffic do not involve the urgency or life-saving aspect that a distress signal embodies.
