A green buoy has a yellow triangle on it. This is a(n) __________.

🔍 Key Concepts

• Intracoastal Waterway (ICW) aids to navigation markings • Meaning of yellow symbols (triangles and squares) added to standard red/green lateral buoys • How ICW marks can be used in combination with normal lateral system buoys

💭 Think About

• Ask yourself: In the U.S. lateral buoyage system, what color and shape are normally used for port and starboard channel markers, and how do yellow shapes modify (not replace) that meaning? • Consider where mariners commonly see yellow triangles and squares on buoys and daybeacons—are they used for errors, off-station buoys, information buoys, or for an additional route? • Think about what it means when the ICW route passes through or along another channel—how do aids to navigation show that a buoy serves more than one purpose?

✅ Before You Answer

• Verify what yellow triangles and yellow squares signify on lateral aids in the U.S. Aids to Navigation System (see USCG Light List or Coast Pilot concepts). • Confirm whether error/off‑station buoys are marked in a standardized way with yellow triangles—or whether they are instead published in Local Notice to Mariners. • Check which answer choice explicitly mentions a combined or overlapping waterway and whether that matches how yellow shapes are actually used.
