What are the colors of a Diving Flag?

The correct answer, red with a white stripe, is the internationally recognized signal for a diving flag. This flag indicates that divers are in the water, and other boaters should maintain a safe distance to avoid accidents. The red background symbolizes the danger associated with diving, while the white stripe running diagonally across the flag serves to attract attention and provide a clear visual indication of the presence of divers below the surface.

Understanding the significance of this flag is crucial for anyone operating a boat in areas where divers might be present, as adhering to this guideline ensures the safety of both the divers and the vessel. Other flag colors mentioned in the options do not represent diving activities and are therefore not applicable in this context. For example, a blue and yellow flag is commonly used for a different purpose, indicating that there are no swimming hazards but does not alert boaters about diver presence.
