How may a distress signal be used?

A distress signal is a crucial method of communication utilized to indicate that a vessel or individual is in danger and requires immediate assistance. The correct answer emphasizes that a distress signal can be used in conjunction with other signals, enhancing its effectiveness and visibility. For example, using visual signals, such as flares, combined with auditory signals, like horns or alarms, increases the likelihood that rescuers will notice the call for help. This multi-faceted approach underscores the importance of drawing attention in various ways to ensure that the distress message is received promptly.

In a broader context, employing multiple signals often creates a higher chance of successfully reaching nearby vessels or emergency services compared to using a single signal in isolation. Therefore, while distress signals can technically exist as stand-alone alerts, their effectiveness is significantly multiplied when combined with other signals during an emergency situation.
