Question 888 Rules of the Road

The correct answer is B) Five short and rapid blasts. The reasoning is that when you are the stand-on vessel in a crossing situation and you believe the give-way vessel is not taking sufficient action to avoid a collision, the International and Inland Navigation Rules (Rule 34(d)) require you to sound five short and rapid blasts on the whistle. This is a warning signal to indicate that you have the right-of-way but the other vessel is not responding appropriately, and you may be forced to take evasive action. The other options are incorrect because: A) is the wrong signal for this situation, C) is the wrong signal since you should not maintain course if the other vessel is not taking action, and D) is incorrect as you are required to sound the warning signal per the Rules.
