What does a flashing amber light signal to boaters?

A flashing amber light is a signaling mechanism used to indicate caution and safety protocols for approaching boaters. When boaters see a flashing amber light, it serves as a directive to approach the lock at a safe speed and to maintain full control of their vessel. This approach ensures that boaters are prepared for any potential changes in the situation, such as the lock being either occupied or ready for entry.

This signaling is crucial for preventing accidents and ensuring the safety of all vessels in the area. It emphasizes the importance of being cautious and in control, rather than rushing or assuming it is safe to proceed without further assessment. By adhering to this signal, boaters are better equipped to react appropriately to conditions and instructions related to the lock, fostering a safer boating environment for everyone involved.
