Question 132Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND While underway at night, you sight a vessel ahead displaying the lights shown in illustration D071RR below. How should the vessels pass?

AI Explanation
The correct answer is B) Both vessels should alter course to starboard and pass port to port.
This is correct because the lights displayed in illustration D071RR indicate that the vessel ahead is a power-driven vessel underway. According to the International Regulations for Preventing Collisions at Sea (COLREGS), when two power-driven vessels are meeting head-on, they should both alter course to starboard and pass port-to-port.
The other options are incorrect because: A) Sounding an overtaking signal is not appropriate in a head-on situation. C) Altering course to port would result in a starboard-to-starboard pass, which is the opposite of the COLREGS requirement. D) Holding course and speed is not the correct action for a head-on encounter.
