Question 761 Rules of the Road

The correct answer is C) underway. The lights displayed in illustration D052RR indicate that the vessel is underway at night. The illustration shows a vessel displaying the required navigation lights for a power-driven vessel underway - a masthead light forward, sidelights (red and green), and a stern light. This lighting configuration is specifically required by the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules for a power-driven vessel underway at night. The other answer choices are incorrect because the lights do not match the requirements for a vessel transferring dangerous cargo (A), aground (B), or at anchor (D).
