Which signals are recognized globally as maritime and aviation emergency signals and must be treated as distress?

• A. Red and White Flares
• B. White Alpha Signals
• C. Flag Signals of Distress
• D. Red and Orange Flares

Answer: (D)

Visual distress signals that are recognized worldwide are red and orange flares. Red flares, whether hand-held or parachute rockets, are used to indicate immediate distress and request urgent assistance, especially at night or in low visibility. Orange flares, typically orange smoke or flame-type signals, provide daytime visibility over a wide area to help rescuers locate you. The combination of red and orange flares is standardized across international maritime and aviation signaling, so any observer—ship or aircraft—must treat their appearance as a distress situation and respond accordingly. Other signals, like white signals or various flag symbols, carry different meanings and are not universally recognized as immediate distress cues, so they aren’t treated the same way.
