Question 131 Rules of the Road

The correct answer is A) Stern light only. In an overtaking situation, the overtaking vessel will see the stern light of the overtaken vessel. This is in accordance with the International Regulations for Preventing Collisions at Sea (COLREGS), which state that the overtaking vessel must pass the overtaken vessel on the safe side, and therefore the overtaken vessel's stern light is the only light that the overtaking vessel will observe. The other options are incorrect because the overtaking vessel would not see the masthead lights, sidelights, or two masthead lights of the overtaken vessel in an overtaking situation.
