What is the color and flashing sequence of an isolated danger buoy?

• A. Green, 2 every 6 seconds
• B. Red, 1 every 3 seconds
• C. White, 2 every 4 seconds
• D. Yellow, 3 every 5 seconds

Answer: (C)

An isolated danger buoy is marked with the color white and displays a specific flashing light sequence to signal boaters. The correct identification of this buoy's color and light pattern is important for navigation safety. The white color signifies that there is danger in the area, but that it is safe to navigate around the buoy, as it indicates the presence of a hazard such as a wreck, shoal, or other underwater obstruction. The flashing sequence of two flashes every four seconds indicates the buoy's isolated status—meaning it marks a single, specific danger rather than a series of hazards. Recognizing this light pattern is crucial for operators to make informed decisions while navigating, as it provides essential information about potential dangers in the waterway. The other options represent different types of navigational aids that serve other purposes and therefore have distinct colors and flashing sequences. These distinctions help ensure that mariners can quickly and accurately interpret buoys and other markers they encounter on the water.
