What are VDS classified as?

Visual Distress Signals (VDS) are classified primarily as day signals, night signals, or signals that can be used during both day and night. This classification is important because different situations and times of day may require specific types of signals to ensure visibility and effectiveness. For instance, some signals like flares are visible both during the day and at night, while others might only be effective in one condition or the other.

Understanding this classification is crucial for boaters, especially in emergency situations, where using the appropriate signal type can significantly increase the chances of being seen and helped. Being aware of when and how to use different signals is also part of safe boating practices, reinforcing the importance of preparedness and understanding the legal requirements for distress signaling.

The other options do not accurately represent the nature of VDS; for example, VDS are not restricted to nighttime use, nor are they exclusively for commercial vessels or recognized solely by the Coast Guard. Effective use of VDS can apply broadly across different types of watercraft and situations.
