What is the main purpose of using "distress signals"?

The primary purpose of using distress signals is to alert nearby vessels and emergency services of a critical situation. Distress signals are specifically designed to communicate that someone is in grave and imminent danger and requires assistance. They can take various forms, including visual signals such as flares, sound signals like horn blasts, and radio communications.

Using distress signals effectively can lead to a swift response from rescuers, potentially saving lives and preventing further emergencies. Therefore, the significance of distress signals lies in their role as a vital means of communication during dire situations at sea, ensuring that those in peril can receive the help they need as quickly as possible.
