Question 323 Rules of the Road

The correct answer is C) special flashing light. According to the Inland Navigation Rules, when two vessels are meeting and will pass 1/4 mile apart, the vessel being overtaken (Vessel "B") must display a special flashing light. This light helps to identify that Vessel "B" is the overtaken vessel and ensures safe passage between the two vessels. The other answer choices are incorrect because: A) the yellow towing light is only required on vessels engaged in towing operations, which is not the case here; B) the red sidelight is a standard navigation light, not a special light used in this situation; and D) not all of these lights would be visible on Vessel "B" in this meeting situation.
