What color lights indicate a power-driven vessel at night?

• A. A red light on the starboard side and a green light on the port side
• B. A green light on the starboard side and a red light on the port side
• C. A white light at the stern and a red light on the port side
• D. A green light at the stern and a white light on the bow

Answer: (B)

Power-driven vessels are required to display specific navigation lights to ensure safe operations at night and in reduced visibility. The correct configuration includes a green light on the starboard side and a red light on the port side. This color coding is standardized within maritime navigation rules and serves as an important tool for identifying the type and direction of a vessel's travel. The green light on the starboard (right) side indicates the vessel's right side when approaching from the front, while the red light on the port (left) side serves the same purpose for the left side. These colored lights are critical for other vessels to determine the relative heading of the power-driven vessel, enabling them to assess the situation and navigate safely around it. Having the correct lights is essential for avoiding collisions, especially since they allow vessels to identify each other's situations in the dark or during limited visibility. This configuration helps promote safety at sea by allowing visual communication between different vessels navigating in close proximity.
