You are sailing south on the Intracoastal Waterway (ICW) when you sight a red nun buoy with a yellow square painted on it. Which statement is TRUE?

Correct Answer: Option A — You should leave the buoy to port.

In the ICW, yellow symbols indicate the route. A yellow square on a red nun buoy signifies that the buoy should be kept to the port side when traveling south. This system overrides standard lateral marks to ensure consistent navigation along the Intracoastal Waterway's unique geographic orientation.
