Which light configuration indicates a vessel is restricted in its ability to maneuver?

The configuration of lights that indicates a vessel is restricted in its ability to maneuver is red over white. This specific light arrangement is used to communicate to other vessels that the vessel displaying these lights is unable to navigate normally due to special circumstances, such as those encountered by vessels engaged in fishing, towing, or working on construction.

When a vessel has this light configuration, it clearly signals to other boats that they should take caution and navigate around it since it might not be able to change its course or speed effectively. This system of maritime signaling is crucial for safety on the water, allowing vessels to communicate their operational status without the need for verbal conversation.

Understanding and recognizing the significance of these light configurations is essential for operators to navigate safely and responsibly.
