Question 440Rules of the Road90% to pass
INTERNATIONAL ONLY In addition to her running lights, a vessel constrained by her draft while underway shall carry which lights in a vertical line?
AI Explanation
The correct answer is D) Three red lights.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel constrained by her draft while underway shall carry three red lights in a vertical line where they can best be seen. This is specified in Rule 28 of the COLREGS, which states that vessels constrained by their draft shall exhibit the lights prescribed for a vessel of her length. The three red lights serve to indicate the vessel's limited ability to maneuver and the need for other vessels to give way.
The other answer choices are incorrect because they do not match the specific lighting requirements for a vessel constrained by its draft as outlined in the COLREGS.
