What does a "diver down" flag look like?

The "diver down" flag is recognized as a red flag with a white diagonal stripe running from the top left corner to the bottom right. This flag is used to indicate that there are divers in the water, alerting other boaters to proceed with caution in the vicinity. The red color signifies the need for attention and caution, while the white stripe communicates that divers are present below the surface, creating a clear visual signal for safety during recreational diving activities.

The other options do not represent the accepted "diver down" flag. A blue flag with a yellow circle is commonly associated with indicating a "diving area" or "divers in the water," but it does not conform to the standard for the diver down flag. The green flag with a diver symbol and the plain orange flag without markings are also not recognized flags in the context of surrounding divers, making them unsuitable representations for this specific purpose. This clear identification of the diver down flag is essential for ensuring the safety of divers and boaters alike.
