In a crossing situation, which vessel may sound the danger signal?

• A. Either vessel
• B. The vessel with the right of way
• C. The vessel making way
• D. The vessel not making way

Answer: (A)

Any vessel may sound the danger signal when there is a danger of collision. In a crossing, the goal is to clearly warn the other vessel if a hazardous situation is developing, and this warning can come from either vessel involved, not just the one with the right of way. The standard danger signal is five short blasts, and it serves to alert the other vessel to take immediate action to avoid collision. This signal is about communicating a hazard, not about asserting which vessel has priority. The other vessel should respond promptly by adjusting course, speed, or both to ensure safe passage. If the danger continues, the signal may be repeated.
