What is the main purpose of visual distress signals?

The main purpose of visual distress signals is to signal for help in emergencies. These signals are crucial for safety on the water, as they alert nearby vessels or rescue services that someone is in trouble and needs assistance. Types of visual distress signals include flares, flags, or lights that can be seen from a distance.

Using these signals effectively can mean the difference between life and death in an emergency situation, as they help ensure that others can quickly locate and respond to individuals in distress. It is important for boaters to be familiar with the various types of distress signals and how to use them properly to maximize their chances of receiving timely help when needed.

Other choices, such as identifying a vessel's type, indicating navigational paths, or assisting in docking, do not relate directly to the primary function of visual distress signals, which is solely focused on emergency communication.
