🔍 Key Concepts

• INLAND Navigation Rules special lighting signals • Meaning of an alternating red and yellow flashing light on the water • Differences between law enforcement and public safety vessel lights

💭 Think About

• Think about which type of vessel would need a highly distinctive, attention‑getting alternating light instead of normal navigation lights alone. • Consider how a distress signal is usually shown at night. Does it normally involve a specific color pattern, or a variety of options? • Ask yourself which choice is specifically tied to government authority versus emergency response roles.

✅ Before You Answer

• Verify which vessel type is assigned an alternating red and yellow flashing light specifically under the INLAND rules. • Confirm what lights a vessel in distress may show and whether a very specific color sequence is mandated. • Check the difference between law enforcement signaling lights and lights used for public safety or restricted maneuverability.
