Question 851Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND A vessel which is unable to maneuver due to some exceptional circumstance, shall show two red lights in a vertical line and which additional lights or shapes?
AI Explanation
The correct answer is A) when making way at night, sidelights and a stern light.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel that is unable to maneuver due to some exceptional circumstance must display two red lights in a vertical line, as well as the normal navigation lights required for a vessel underway, which includes sidelights and a stern light.
The other options are incorrect because they do not accurately describe the lighting requirements for a vessel that is unable to maneuver. Option B and C describe shapes, not lights, which are used for vessels that are not underway. Option D includes additional lights, such as masthead lights, which are not required for a vessel that is unable to maneuver.
