What is indicated by the SOS Morse Code signal?

The SOS Morse Code signal is universally recognized as an urgent call for help indicating that the sender is in distress and requires immediate assistance. It is a standard distress signal used in emergency situations, particularly in maritime contexts. The SOS is not only easy to transmit due to its simple dot and dash sequence, but it has also become synonymous with emergencies, making it instantly recognizable to those who receive it. This signal can be transmitted in various forms, including visually (like flashing lights) or audibly (like radio signals), and it conveys a dire need for aid.

The other choices do not accurately reflect the purpose of the SOS signal. A general warning does not convey the urgency of distress, while a request for a tow is a specific maritime action that does not necessarily indicate danger. Similarly, a fishing alert is unrelated to the need for emergency assistance. Thus, the correct interpretation of the SOS signal is that it signifies a clear and immediate distress situation needing help.
