🔍 Key Concepts

• Inland Aids to Navigation marking system for regulatory/information buoys • Difference between orange symbols: diamond, diamond with cross, circle, and square/rectangle • Purpose of white buoys with orange markings vs. mooring buoys

💭 Think About

• Think about which symbol shape is used to show a specific rule like speed limit or no wake, rather than a general warning or exclusion. • Ask yourself: which of these answer choices describes a rule you must follow in that area, not a physical hazard or a place you must stay completely out of? • Recall what color and markings a true mooring buoy has, and whether it normally uses orange symbols.

✅ Before You Answer

• Match the orange circle symbol to its meaning in the aids-to-navigation system (NOT the diamond or diamond-with-cross). • Confirm which markings are used for danger and for vessels excluded and eliminate those shapes from consideration for a circle. • Verify that a mooring buoy has a different color scheme and does not use an orange regulatory symbol.
