When you see a red and white light at night, what is your responsibility?

Seeing a red and white light at night indicates that you are approaching another vessel that is restricted in its ability to maneuver or is at anchor. The presence of these lights informs you of the other vessel's position and situation, which is crucial for safe navigation.

As the give-way vessel, your responsibility is to take action to avoid a collision. This generally means altering your course or speed to ensure a safe distance from the other vessel, which may include slowing down or steering away. Recognizing your role as the give-way vessel helps prevent accidents and promotes navigational safety.

Understanding this context is essential for all boaters to navigate responsibly and adhere to maritime rules. The other options such as maintaining course, being the stand-on vessel, or increasing speed do not align with the required actions when you encounter a red and white light; they could potentially lead to dangerous situations on the water.
