Question 435Rules of the Road90% to pass
INTERNATIONAL ONLY Which vessel would display three red lights in a vertical line?
AI Explanation
The correct answer is B) A vessel constrained by her draft.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel constrained by her draft is required to display three red lights in a vertical line as a visual signal to indicate her status. This signals to other vessels in the area that the constrained vessel has limited ability to maneuver and may require additional space or clearance to safely navigate.
The other options are incorrect because they do not match the specific signaling requirements for a vessel constrained by her draft under the COLREGS. A vessel aground, a vessel dredging, or a vessel not under command would have different light configurations to indicate their respective statuses.
