Connecticut Safe Boating Practice Test

What indicates that a commercial vessel is towing or pushing a barge?

1. A white light at the stern

2. A series of red lights

3. A yellow light in place of the sternlight

4. A green light on the starboard side

The correct answer is: A yellow light in place of the sternlight

A yellow light in place of the sternlight is the correct indicator that a commercial vessel is towing or pushing a barge. This is a specific visual cue that is part of the navigation rules established to ensure safety on the water. The yellow light signals to other vessels that the towing vessel is engaged in a tow operation, which necessitates caution from anyone near the vessel, indicating that there may be limited maneuverability or additional hazards associated with the towed barge. Understanding the purpose of navigation lights is crucial for safe boating practices. Each color and its placement convey specific information regarding the vessel's activities and help prevent accidents. Other light combinations, such as series of red lights or green lights on the starboard side, serve different functions and do not communicate the same information about towing operations. The use of a white light at the stern also does not indicate towing; it simply signifies the rear position of a vessel.
