Question 4968 Deck General

The correct answer is A) a single blue rotating light. According to the United States Coast Guard regulations, icebreakers are not permitted to use a single blue rotating light when escorting ships in ice. This light is typically reserved for law enforcement and emergency vehicles. The other options, including a single amber rotating light, a single red rotating light, and red aircraft warning lights, are all acceptable distinctive lights that a U.S. Coast Guard icebreaker may use when escorting ships in ice.
