What does the danger signal indicate?

• A. Doubt about another vessel's actions
• B. A request for assistance
• C. A warning of danger in the waterway
• D. An instruction to alter course

Answer: (A)

The danger signal communicates doubt about another vessel’s actions. When you’re not confident about what the other vessel intends to do—whether they’ll turn, slow, speed up, or pass on a certain side—you use this signal to let them know you’re uncertain and to prompt them to clarify or adjust their maneuver. This helps reduce the risk of collision by encouraging predictable behavior and can prompt a response from the other vessel. It’s not a request for help, it doesn’t signify a general danger in the waterway, and it isn’t an instruction for you to alter course—that would be a different type of signal or instruction. If you observe or hear the danger signal, slow down, keep a safe distance, and be ready to react once the other vessel’s intentions become clear.
