What action should be taken when a vessel displays a flag indicating distress?

When a vessel displays a flag indicating distress, the appropriate response is to proceed toward the vessel. The reason this is the best course of action is that the distress signal indicates an urgent situation where the crew may require immediate assistance. Approaching the vessel can facilitate a timely response, potentially saving lives or helping to resolve a dangerous situation.

Monitoring for further instructions is not as proactive as going to the distressed vessel. While maintaining a safe distance may seem prudent to avoid further danger, it can also delay necessary assistance. Ignoring the signal altogether is unacceptable, as it could lead to a tragic outcome if the vessel in distress is in critical need of help. Thus, moving towards the vessel aligns with maritime safety practices and the obligation to aid others in distress.
