In navigation, what does a steady red light typically indicate?

A steady red light in navigation generally signals that a vessel must stop. This indication is standard for various navigational contexts, such as entering a harbor or approaching a bridge. The red light serves as a clear and unequivocal warning to mariners that proceeding further could lead to dangerous situations, either due to obstacles, oncoming traffic, or restricted areas that may require caution or stopping.

Maritime navigation uses a color-coded system for lights to convey specific instructions to vessels. A steady red light is universally recognized as a stop signal, making it crucial for safety and compliance while navigating. Understanding these signals is essential for vessel operation and ensuring the safety of all who are on the water.
