Question 95Rules of the Road90% to pass

INLAND ONLY Your power-driven vessel is overtaking another power-driven vessel in a narrow channel. You wish to overtake her on her starboard side. Which whistle signal should you sound?

AI Explanation
The correct answer is D) one short blast. When overtaking another power-driven vessel in a narrow channel, the vessel being overtaken has the right-of-way. To indicate your intention to overtake on the starboard (right) side, you should sound one short blast on your whistle. This signals to the other vessel that you intend to pass on their starboard side. The other options are incorrect because they do not align with the proper whistle signal for this situation under the Inland Navigation Rules.
