When visibility is restricted, what should a vessel do to communicate with others?

• A. Use signals to communicate intentions.
• B. Rely solely on electronic navigation without signaling.
• C. Ignore signals to avoid confusion.
• D. Use only sound signals.

Answer: (A)

In restricted visibility, making your presence and intended maneuver clear to other vessels is essential to prevent collisions. You should communicate your actions through signals that are appropriate for the situation. This means using the available signaling methods—sound signals in fog, and where possible, light signals or radio communications—to convey how you plan to change course or speed. Relying solely on electronic navigation without signaling can leave others unaware of your intentions, and using only sound signals may not fully convey your exact maneuver. Using signals to communicate intentions best supports safe, predictable movements in poor visibility.
