Question 778 Rules of the Road
90% to passBOTH INTERNATIONAL & INLAND You are approaching another vessel at night. You can see both red and green sidelights and, above the level of the sidelights, three white lights in a vertical line. Which vessel is required to have these lights?
The correct answer is D) a vessel towing a tow more than 200 meters astern. According to the International and Inland Navigation Rules, a vessel towing another vessel or object that is more than 200 meters astern is required to display three all-round white lights in a vertical line, in addition to the red and green sidelights. This configuration of lights helps identify the vessel as one that is towing a long tow. The other options are incorrect because they do not match the lighting configuration described in the question. A vessel not under command, a vessel underway and dredging, and a vessel trawling have different lighting requirements that do not include the three vertical white lights.
