Question 335 Rules of the Road

The correct answer is B) Sound the danger signal. The reasoning is that when you are meeting another power-driven vessel head-on and you sound one short blast as a passing signal, but the other vessel answers with two short blasts, this indicates the other vessel does not understand or intend to take the action you proposed. In this situation, the proper action is to sound the danger signal, which is five or more short and rapid blasts, to indicate you do not understand the other vessel's intentions and to warn them of a potentially dangerous situation. The other answer choices are incorrect because: A) Passing astern of the other vessel is not the appropriate action when the other vessel has indicated it does not understand your proposed action. C) Passing on the other vessel's starboard side is also not the correct action in this scenario. D) Holding your course and speed is also not the right choice, as you need to take action to avoid a collision.
