🔍 Key Concepts

• Inland river aids to navigation and what different light colors (red, green, amber) generally indicate • Meaning of a flashing amber (yellow) light on the bank in river navigation, especially near bends or crossings • Relationship between bank lights and the preferred side of the channel or safe water

💭 Think About

• Think about where bank lights are usually placed on rivers: Are they telling you which bank to hug, or are they marking something else related to the channel? • Compare what each choice tells you to do with respect to the right descending bank—does the light usually tell you to move toward that bank, away from it, or to remain in some particular part of the channel? • Ask yourself: does an amber light normally mean danger/obstruction, a work area like dredging, or a navigation guidance to stay in a certain area of the channel?

✅ Before You Answer

• Verify what a flashing amber (yellow) bank light is defined to mean in inland river navigation references (Coast Pilot, river charts, or aids-to-navigation guides). • Check whether dredging operations would be marked only by a single flashing amber light on the bank, or by a different combination of lights and shapes. • Confirm whether the instruction is usually to keep near a bank or in the channel/deepest water when you see this type of bank light.
