Question 786Rules of the Road90% to pass

BOTH INTERNATIONAL & INLAND Which light(s) shall a vessel being towed astern show?

AI Explanation
The correct answer is B) sidelights. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel being towed astern is required to show sidelights (green on the starboard side and red on the port side). This is specified in Rule 24(e) of the COLREGS, which states that "a vessel being towed shall show the sidelights." The other options are incorrect because a vessel being towed is not required to show masthead lights (option A), a special flashing light (option C), or all of the above (option D). The sidelights are the only lights that are specifically required for a vessel being towed astern under the COLREGS.
