🔍 Key Concepts

• Inland navigation lights and signals for bridges in 33 CFR Part 118 • How the draw or center of the navigable channel under a bridge is indicated to vessels • Differences between regulatory shapes/signs (like diamonds) and light configurations used at night

💭 Think About

• Think about what mariners most need to know when approaching a floating drawbridge at night: what specifically has to be clearly identified for safe passage? • Consider which option sounds like a standard, codified light arrangement rather than a general warning shape or color. • Ask yourself: which of these patterns would clearly mark the exact location where the draw opens, not just the presence of a bridge?

✅ Before You Answer

• Verify in 33 CFR Part 118 – Bridge Lighting and Other Signals what configuration is prescribed for the draw span opening. • Check which options use lights versus dayboards/signs; floating drawbridge draw-span marking is primarily a light signal question. • Confirm whether the correct configuration is symmetrical on each side of the draw opening so a vessel can line up with the safe passage.
