Question 853Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND Two all-round red lights displayed in a vertical line are shown by which vessel?
AI Explanation
The correct answer is C) not under command.
According to the International and Inland Navigation Rules, a vessel displaying two all-round red lights in a vertical line is indicating that it is "not under command." This means the vessel is unable to maneuver as required by the rules and is therefore unable to keep out of the way of other vessels.
The other answer choices are incorrect because they do not match the specific lighting configuration described in the question. Vessels at anchor, pushing a barge, or being towed would display different light signals to indicate their status and navigation.
