If you are communicating with another station and hear a station in distress break in, what should you do?

Distress communications have absolute priority over all other transmissions on amateur radio frequencies. If you hear a station in distress break into your ongoing conversation, it is your legal and moral obligation to immediately stop your routine traffic and address the emergency. You must acknowledge the calling station to let them know they have been heard. Your primary goal is to gather critical information, specifically their exact location and the nature of the assistance they require, so you can rapidly relay this to the proper authorities. Simply ceasing all transmissions or changing frequencies is incorrect and dangerous. If you abandon the frequency, you might be the only person who heard their call, leaving the distressed station without vital help.
