🔍 Key Concepts

• Inland Navigation Rules – special signals for dredging/underwater operations (think about how obstructions and safe passages are marked at night) • Meaning of pairs of vertical red lights versus flashing yellow lights on inland waters (do they mark safe water or danger?) • How dredge pipelines or construction areas are lighted to show you where you may and may not pass

💭 Think About

• First decide what kind of situation this is: another vessel under way, or fixed aids/markers around an obstruction? What do multiple fixed yellow flashing lights in a row usually indicate on rivers and channels? • Ask yourself: Do red lights in vertical pairs usually mean “go here” or “do NOT go here”? Once you answer that, which side or area in the picture likely represents the safe passage for your vessel? • Look at the symmetry of the lights. If a pipeline or obstruction is running across the channel, how would the lights be arranged to show you the ends of the obstruction and the route you should take?

✅ Before You Answer

• Be sure you can clearly identify which lights are marking the obstruction and which are marking the safe channel or passing area. • Confirm from your Inland Rules study materials how dredge/pipeline markings are arranged at night, especially the role of red vs yellow flashing lights. • Before choosing an option, match the described maneuver (waiting, stopping, passing between reds, or leaving all lights to starboard) with what you know about how to safely pass a dredging or pipeline operation.
