What does the term “Securité” indicate in radio communications?

The term "Securité" in radio communications is specifically used to indicate safety messages. When a radio operator transmits a message prefaced by "Securité," it alerts listeners to potential hazards or important safety information related to navigation or maritime operations. This could include warning about adverse weather conditions, navigational dangers, or other situations that could pose a risk to safe navigation. It is a crucial element of maritime communication meant to protect life and property at sea.

Other options, while related to maritime communication, do not accurately define "Securité." Distress signals require immediate assistance but are indicated by different terms such as "Mayday." General communications between vessels, while important, lack the specific safety emphasis that "Securité" embodies. Similarly, confirmations of arrival are operational messages that do not communicate safety information in the way that "Securité" does.
