What type of signal is considered an international distress signal?

• A. A continuous blast on the ship's whistle
• B. A series of five short blasts followed by a long blast on the ship's horn
• C. A single explosion of fireworks
• D. Raising and lowering a flag

Answer: (B)

A series of five short blasts followed by a long blast on the ship's horn is recognized as an international distress signal. This specific sound pattern is important because it conveys an urgent message to other vessels and nearby parties that there is a serious issue that requires immediate assistance. The sequence of blasts is distinctive and easily recognizable, making it a reliable method for signaling distress. The use of sound signals is particularly critical in maritime settings where visual contact may be limited, and other methods of communication may fail. Such signals are part of the established maritime protocol under the International Regulations for Preventing Collisions at Sea (COLREGs) and the International Maritime Organization (IMO) guidelines. This ensures a standardized understanding among seafarers internationally, enhancing safety at sea.
