🔍 Key Concepts

• INLAND Navigation Rules – Rule 34 (Maneuvering and Warning Signals) • Use of light signals instead of or in addition to whistle signals for passing intentions • Which colors and characteristics are permitted for these passing-intention lights (color + all-round)

💭 Think About

• Think about what kind of light is allowed to be used in place of or along with whistle signals to indicate passing on the Inland Waters. • Ask yourself: when a vessel is showing its passing intentions by light at night, what color(s) does the rule specifically permit, and what shape/sector (all-round or not) must that light be? • Compare each answer choice with the rule: Which choices describe a light that clearly matches the permitted colors and is described as all-round for signaling maneuvers?

✅ Before You Answer

• Verify in Rule 34 that the passing-intention light must be all-round (visible through 360°). • Check exactly which colors are authorized by the Inland Rules for these maneuvering signals (is it only white, only yellow, white or yellow, or red/yellow?). • Eliminate any options that include a color combination or flashing pattern not mentioned in Rule 34 for passing-intention lights.
