🔍 Key Concepts

• Rule 34(d) – Maneuvering and Warning Signals in the Navigation Rules • The purpose of the danger signal (five or more short, rapid blasts)** • Responsibilities of stand-on vessel vs give-way vessel in a crossing situation

💭 Think About

• Ask yourself: In any situation where there is doubt or confusion about another vessel’s intentions, who is allowed to indicate that doubt with a danger signal? • Think about whether the danger signal is tied to a specific role (stand-on or give-way) or to the existence of doubt about the situation. • Consider if the rules ever limit the use of danger signals to only one vessel in a meeting, crossing, or overtaking situation.

✅ Before You Answer

• Verify in Rule 34 that the danger signal is used when there is doubt as to the other vessel’s intentions or actions. • Check whether Rule 34(d) says the danger signal is restricted to only one type of vessel (stand-on or give-way) or not restricted. • Confirm that the question is specifically about a crossing situation, but the rule for danger signals applies to all situations where doubt exists, not just one type.
