What does a diver's flag look like?

The correct answer is a rectangle red flag with a white diagonal stripe, commonly referred to as the diver's flag. This flag, often utilized by scuba divers and snorkelers, is a signal to indicate that there are divers in the water and that vessels should keep a safe distance. The red color signifies danger, while the white diagonal stripe serves as a recognizable and iconic symbol for caution in the boating community.

Boaters encountering this flag should be aware that divers are present below the surface, making it important to navigate carefully to avoid disturbing them. Understanding the significance of this flag is crucial for anyone operating a boat, as it promotes safety and prevents accidents that could occur when a diver is in close proximity to watercraft.

Each of the other choices represents flags associated with different meanings or uses—such as the blue and white striped flag or the orange flag with a black circle—but they do not represent the specific warning for divers in the water. Proper recognition of the diver's flag is vital for maintaining a safe environment for both divers and boaters.
