Connecticut Safe Boating Practice Test

What does a single white light signify when encountered at night?

1. Power-driven vessel which must give way

2. Sailing vessel which must stand on

3. Vessel that is anchored

4. All-around white light

The correct answer is: Power-driven vessel which must give way

A single white light when encountered at night indicates a vessel that is anchored. This type of light is used to show that a vessel is not underway and is stationary. The purpose of this signaling is for the safety of navigation, as it alerts other vessels to the presence of an anchored craft, allowing them to avoid potential collisions. In addition, an anchored vessel is required to display a single white light if it is not at anchor in a designated area, following the rules set out in the navigation regulations. Understanding the significance of these lights is crucial for safe boating practices, especially during nighttime operations when visibility can be limited. Recognizing a single white light means that the observing vessel should be aware of its surroundings and take necessary caution while navigating in the vicinity.
