What feature distinguishes lighted buoys from others?

Lighted buoys are distinguished by their ability to convey navigational information through both the visual power of lights and the shape, color, and numbering system used. The correct choice highlights that lighted buoys can adopt various shapes and colors that correspond to lateral markers in navigation. These features are important for boaters because they help indicate safe passage, channel boundaries, and hazards in the water.

Unlike other types of buoys that may serve specific localized purposes without such visual aids, lighted buoys enhance visibility during nighttime or low-visibility conditions, allowing boaters to navigate safely. The combination of physical characteristics—like being cylindrical, rectangular, or otherwise—does not limit the information a buoy can offer. In fact, while many buoys are marked uniquely, the key aspect of lighted buoys is the additional layer of navigational guidance provided by their lights, shapes, and colors that align with established navigation rules.
