INLAND ONLY You are overtaking another power-driven vessel and sound a whistle signal indicating that you intend to pass the vessel along her starboard side. If the other vessel answers your signal with five short and rapid blasts, what action should you take?

Correct Answer: Option C — not overtake the other vessel until both vessels exchange the same passing signal

33 CFR 83.34(d) states that if a vessel is in doubt as to the intentions of another, it must sound the danger signal of at least five short and rapid blasts. Overtaking cannot proceed until both vessels have exchanged and agreed upon the same passing signal.
