Question 198 Rules of the Road

The correct answer is B) white stern light. According to the International Regulations for Preventing Collisions at Sea (COLREGS), when a vessel is overtaking another vessel, the overtaking vessel (Vessel A) shall keep out of the way of the vessel being overtaken (Vessel B). In this situation, Vessel A will observe the white stern light of Vessel B, as the stern light indicates the direction the vessel is heading. The other answer choices are incorrect because: A) the green sidelight would not be visible from the overtaking position, C) the yellow towing light is not relevant in this scenario of a simple overtaking maneuver.
