Question 735Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND While underway at night you are coming up on a vessel from astern. What lights would you expect to see?
AI Explanation
The correct answer is A) One white light.
According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a vessel underway at night and being overtaken from astern should display a single white stern light. This light helps indicate the vessel's presence and orientation to the overtaking vessel.
The other options are incorrect because: B) Red and green sidelights are displayed on the sides of the vessel, not the stern; C) Two white lights would indicate a towing vessel, not a standard underway vessel; and D) One white light, without sidelights, is the correct configuration for an overtaken vessel at night.
