Question 377 Rules of the Road

90% to pass

INLAND ONLY You are overtaking another power-driven vessel in a narrow channel. The other vessel will have to move to allow you to pass. You wish to overtake the other vessel and leave her on your starboard side. What should be your first whistle signal?

A one short blast
B two prolonged blasts followed by two short blasts
C two prolonged blasts followed by one short blast
D two short blasts
AI Explanation

The correct answer is D) two short blasts. According to the Inland Navigation Rules, when overtaking another power-driven vessel in a narrow channel, the overtaking vessel should signal their intention to pass by sounding two short blasts. This lets the other vessel know that you wish to pass them on their starboard (right) side. The two short blasts indicate your intent to overtake and pass. The other answer choices are incorrect because: A) one short blast is used to indicate you are altering course to starboard, B) and C) do not correctly signal your intent to overtake and pass on the starboard side.
