Question 56 Rules of the Road

90% to pass

INLAND ONLY Two vessels are in a starboard to starboard meeting situation and will pass well clear approximately 1/4 mile apart. Which action should each vessel take?

A Sound a one blast whistle signal and turn to starboard.
B Maintain course and sound no signal.
C Sound a three blast whistle signal and turn to port.
D Sound a two blast whistle signal and maintain course.
AI Explanation

The correct answer is D) Sound a two blast whistle signal and maintain course. This is the correct action because in a starboard-to-starboard meeting situation, the International Regulations for Preventing Collisions at Sea (COLREGS) state that the vessels should maintain their course and speed, and sound two short blasts on the whistle to indicate that they intend to maintain course. The other options are incorrect because A) turning to starboard would be the wrong action, C) turning to port would be the wrong action, and B) sounding no signal would not properly communicate the vessels' intentions to each other.
