🔍 Key Concepts

• Annex IV – Distress Signals of the Navigation Rules • Differences between pyrotechnic distress signals (flares, rockets) and other lights/colors • Which colors and patterns are officially reserved for distress

💭 Think About

• Look at each option and ask: Does this exact color or action appear in the official list of distress signals in Annex IV? • Think about what colors are traditionally associated with distress at sea, and which are used for other purposes like illumination or signaling but not distress. • Consider whether arm signals are included in the Navigation Rules distress list, or if they belong more to small-craft/near-shore signaling practices.

✅ Before You Answer

• Verify which flare/signal colors are explicitly named as distress in Annex IV (e.g., rockets, stars, hand flares). • Check if orange smoke is on the official distress list or just a common safety item. • Confirm whether the specific color mentioned in one of the options is ever listed as a distress signal in the Navigation Rules.
