Question: 1 / 400

If you see a red, a green, and a white light on another boat, what does this indicate?

A boat is anchored

A boat is approaching you head-on

Seeing a red, a green, and a white light on another boat indicates that the vessel is approaching you head-on. When observing navigation lights at night or in poor visibility conditions, the red light represents the port side (left), the green light represents the starboard side (right), and the white light typically indicates the stern of the vessel.

If you can see all three lights simultaneously, it signifies that the other boat is approaching from the front because you can see both side lights along with the white stern light. This visibility pattern is consistent with vessels on a collision course, which is why it's crucial for operators to understand navigation light configurations for safe boating practices, particularly to ensure appropriate actions can be taken to avoid collisions.
