Why are distress signals standardized internationally?

Distress signals are standardized internationally primarily to ensure effective communication among different countries during emergencies. In situations where lives are at risk, it is crucial that signals are universally recognized and understood, regardless of language barriers or local practices. Standardization allows for quick and efficient responses from rescue services and other vessels in the vicinity, increasing the likelihood of successful assistance and coordination during distress situations.

By having a consistent set of signals, mariners and rescuers can interpret distress calls accurately and without ambiguity, fostering a cooperative and effective response. This international agreement on signals stems from conventions such as the International Convention on the Safety of Life at Sea (SOLAS), which underscores the importance of such standardization for maritime safety and efficiency.
