🔍 Key Concepts

• Regulatory/informational buoys in the U.S. Aids to Navigation System (orange and white buoys) • The four basic shapes/symbols used: diamond with cross, open-faced diamond, circle, and square • The specific meanings of danger, exclusion, controlled area, and information

💭 Think About

• First, match each symbol with its meaning: which one means areas where boats are totally kept out, and which one simply warns of hazards? • Ask yourself: does a danger marking mean "no entry at all" or "be careful"? Then recall which symbol matches that level of restriction. • Think about what kind of symbol would logically be used to show general information versus a specific hazard.

✅ Before You Answer

• Be sure you know which symbol marks an exclusion area (no boats allowed) versus a danger area (hazard present) • Confirm which symbol is used for controlled areas (like speed limits) so you don’t mix it up with danger markings • Verify which symbol is used for information and directions; once you know that, eliminate that choice from the danger options
