Question 903Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND You are on a vessel nearing a bend in the channel where, because of the height of the bank, you cannot see a vessel approaching from the opposite direction. Which signal should you sound?
AI Explanation
The correct answer is C) One prolonged blast.
The reasoning is based on the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, which both require a vessel approaching a bend in the channel where other vessels cannot be seen to sound "one prolonged blast" to indicate their presence and position. This signal alerts any approaching vessels to the presence of your vessel, allowing them to take appropriate action.
The other options are incorrect because they do not align with the COLREGS and Inland Navigation Rules for the given scenario. Five or more short blasts (A) is the signal for danger, three short blasts (B) is the signal for going astern, and one short blast (D) is the signal for a course alteration to starboard.
