Question 864 Rules of the Road

The correct answer is A) Three lights in a vertical line, the highest and lowest red and the middle white. This is the correct answer because the International Regulations for Preventing Collisions at Sea (COLREGS) state that a vessel restricted in her ability to maneuver must exhibit three all-round lights in a vertical line, the highest and lowest being red and the middle one being white. This lighting configuration helps to identify the vessel as one that is restricted in its ability to maneuver, allowing other vessels to take appropriate action to avoid a collision. The other options are incorrect because they do not match the required lighting configuration specified in the COLREGS for a vessel restricted in her ability to maneuver.
