Question 681 Rules of the Road

The correct answer is B) on pilotage duty and underway. The lights shown in illustration D078RR indicate that the vessel is on pilotage duty and underway. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel engaged in pilotage duty must display two all-round red lights in a vertical line at the fore part of the vessel. This configuration of lights identifies the vessel as being on pilotage duty and underway. The other answer choices are incorrect because the lights do not match the descriptions for a vessel not under command (A), a vessel restricted in its ability to maneuver (C), or a fishing vessel making way (D).
