Question 788 Rules of the Road

The correct answer is A) a towing light in a vertical line above the stern light. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a power-driven vessel towing astern is required to show a towing light in a vertical line above the stern light. This is specified in Rule 24(c) of the COLREGS, which states that a vessel towing astern shall show the same lights as a power-driven vessel, with the addition of a towing light in a vertical line above the stern light. The other answer choices are incorrect because they do not accurately reflect the COLREGS requirements for a power-driven vessel towing astern. Option B and C require additional towing lights that are not mandated, while option D calls for a light in lieu of the stern light, which is not the correct configuration.
