Describe the characteristics of hand-held flares.

Hand-held distress flares are red because red light stands out best against the dark night sky and sea, making it easy for rescuers to spot you from a distance. The key purpose is to mark your exact location, not to indicate distance to shore. Because they are most visible in low light, they’re used at night. The other options mix colors or times with the wrong signal purpose—daytime signaling relies on different signals, and orange or white signals aren’t the standard for pinpointing your position at night. So, a red flare used at night to mark your precise location is the correct description.
