Question 316 Rules of the Road

The correct answer is B) White. According to the United States Coast Guard regulations, a fleet of moored barges extending into a navigable channel must display white lights at night. This is to ensure that the presence of the barges is clearly visible to other vessels navigating the channel, thus preventing collisions. The other answer choices are incorrect because yellow, amber, and red lights are not the required colors for this situation. Yellow and amber lights are typically used for cautionary or warning purposes, while red lights are reserved for port-side navigation lights on vessels.
