Question 329 Rules of the Road

The correct answer is B) special flashing light. When two inland vessels are meeting and will pass 1/4 mile apart, the International Regulations for Preventing Collisions at Sea (COLREGS) require the vessel on the right (in this case, vessel "B") to display a special flashing light. This flashing light alerts the other vessel ("A") that the vessels are in a meeting situation and must take appropriate action to safely pass each other. The other answer choices are incorrect because a yellow towing light is not required in a meeting situation, and red sidelights are used to indicate the port (left) side of the vessel, not for meeting lights.
