Question 966 Deck General

The correct answer is B) Red light. According to the regulations for tank barges, a red light must be displayed at night to indicate that the barge is loading or discharging flammable liquid cargo. This requirement is specified in the Code of Federal Regulations (CFR) for tank vessels, which states that a red light must be used to mark a barge that is "engaged in the transfer of flammable or combustible liquid cargo in bulk." The other options are incorrect because they do not match the specific regulatory requirement for a red light. Flashing amber lights, ICC yellow lights, and two orange lights are not the proper signals for this situation as per the Coast Guard regulations.
