INLAND ONLY A flashing blue light is used to identify which of the following vessels?

A dredge pipelines on trestles
B air-cushion vessels in the non-displacement mode
C law enforcement vessels
D U.S. submarines
AI Explanation

The correct answer is C) law enforcement vessels. The reason this is the correct answer is that under the U.S. Coast Guard regulations, law enforcement vessels are required to display a flashing blue light to identify themselves while operating. This helps other vessels recognize them as government law enforcement craft. The other answer choices do not meet this specific regulation for the use of a flashing blue light.
