What does a signal of “SOS” symbolically represent?

The signal "SOS" is internationally recognized as a distress signal, symbolizing an emergency situation. This three-letter signal is used as a call for help, indicating that the sender is in urgent need of assistance. Historically, "SOS" was chosen because it is easy to recognize in Morse code, consisting of three dots, three dashes, and three dots (---), which makes it unmistakable in audio or visual formats.

In maritime communication, "SOS" conveys a serious alert, and it should prompt immediate action from nearby vessels and rescue services. By knowing that "SOS" represents an emergency, mariners can prioritize their responses to assist those in distress effectively. Other signals may denote different situations, but none carry the same weight of urgency as "SOS," which is why it is crucial for every mariner to be aware of its meaning and significance.
