Question 880 Rules of the Road

The correct answer is B) A bell and a whistle. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, vessels 20 meters (approximately 24 meters) in length and upwards are required to carry a bell and a whistle as the minimum sound signaling equipment. This requirement ensures that the vessel can make the necessary sound signals to communicate its presence and navigational intentions to other vessels, as per the collision avoidance regulations. The other options are incorrect because A) any means of making an efficient sound signal is not specific enough, C) a bell only does not meet the minimum requirement, and D) a whistle only also does not meet the minimum requirement for a vessel of this size.
