Question 248 Rules of the Road

You are correct, the answer is C) hold course and speed. This is the correct action because the lights shown in illustration D050RR represent the lights of a vessel that is overtaking you, coming up from behind on your port (left) side. According to the International and Inland Navigation Rules, the proper action for the vessel being overtaken is to hold course and speed, allowing the overtaking vessel to safely pass. The other answer choices are incorrect because stopping the engines or altering course to port would impede the safe passage of the overtaking vessel, and sounding the danger signal is not the appropriate action in this scenario.
