What is the requirement for using red flares and red meteors in visual distress signaling?

The requirement for using red flares and red meteors in visual distress signaling is that a boat must carry a combination of signaling devices that are able to attract attention effectively. The answer indicates that having one handheld red flare along with two red meteors satisfies the legal requirement for visual distress signaling.

Handheld red flares are effective for alerting nearby vessels or people that you are in distress, as they are highly visible against the backdrop of water and sky. Red meteors, which are fired into the air and explode into a red flare, also serve the same purpose but can be viewed from a greater distance and provide a different signal method. The mixture of these signaling devices enhances visibility and ensures that the distress signal is recognized by passing boats or rescue personnel.

The law mandates a specific number of devices to ensure redundancy and increase the chances of rescue, which is why this combination meets the legal requirement. Other combinations might not provide the necessary visibility or quantity for effective signaling in a distress situation.
