What color is the starboard side light?

• A. Red
• B. Green
• C. Blue
• D. White

Answer: (B)

The starboard side light is green as part of maritime navigation and safety regulations. In maritime practices, vessels are required to display specific colored lights to indicate their direction to other boats. The starboard side is traditionally associated with the color green, while the port side is red. This color-coding allows sailors to quickly identify the orientation and movement of other vessels during day or night operations.

The green light on the starboard side is visible from a distance and plays a crucial role in the rules of the road at sea, helping to prevent collisions by indicating which direction a vessel is facing. The navigation lights on vessels follow the International Regulations for Preventing Collisions at Sea (COLREGs), necessitating that each side of a vessel displays its respective color light.
