Question 442Rules of the Road90% to pass

INTERNATIONAL ONLY A vessel constrained by her draft may display which lights?

AI Explanation
The correct answer is D) Three all-round red lights in addition to the lights required for a power-driven vessel of her class. A vessel constrained by her draft, as per the International Regulations for Preventing Collisions at Sea (COLREGS), is required to display three all-round red lights in addition to the regular navigation lights required for a power-driven vessel of her class. This distinguishes the vessel as being constrained by her draft, which means she has limited maneuverability due to her deep draft. The other options are incorrect because they do not accurately reflect the lighting requirements for a vessel constrained by her draft under the COLREGS.
