INLAND ONLY You are aboard the stand-on vessel in a crossing situation. You sound a one blast whistle signal. The give-way vessel answers with a two blast whistle signal. You should sound the danger signal and take what action?

Correct Answer: Option C — take precautionary action until a safe passing agreement is made

When a disagreement occurs regarding a maneuver, Rule 34(d) requires the sounding of the danger signal (at least five short and rapid blasts). You must then take immediate, safe, and precautionary action to avoid a collision until a clear passing agreement is established between the vessels.
