What is the primary purpose of the International Code of Signals?

• A. To provide standardized signals for communication between ships.
• B. To set port tariffs.
• C. To describe weather patterns.
• D. To manage fishing quotas.

Answer: (A)

The main idea this question tests is that ships rely on a shared language for clear, quick communication. The International Code of Signals creates a standard set of signals using flags, shapes, lights, and later radio codes, so vessels and shore stations understand each other no matter what language the crews speak. This universal signalling system is essential for safety at sea, enabling quick distress, safety, and navigational messages to be understood worldwide. The other options don’t relate to signaling—port tariffs, weather descriptions, and fishing quotas are handled in different domains, not through standardized ship signals.
