What does a loud signal or warning from a ship’s horn indicate?

A loud signal or warning from a ship’s horn indicates a critical situation, often signaling distress, particularly in immediate proximity to other vessels. This use of the horn serves as an urgent alert that draws attention to the ship in trouble, conveying to nearby ships that immediate action might be required to assist or respond. It emphasizes safety by ensuring that other vessels are aware of potential dangers or emergencies that may threaten the wellbeing of those on board.

In the context of maritime communication, other reasons for sounding a horn, such as celebration or routine communication, do not involve a loud signal interpreted as a distress call. Such sounds are typically governed by specific regulations and customs that dictate when and how different signals should be used, which helps maintain clarity in critical situations at sea.
