What should a boat operator do if they see a flag with a diagonal red stripe?

Seeing a flag with a diagonal red stripe is an important visual signal on the water. It indicates the presence of a diver below. This flag serves to warn other boaters to exercise caution and to maintain a safe distance from the area where the diver is located. The diver down flag is a critical safety measure designed to protect divers, as boat traffic can be a significant hazard to those underwater.

Being aware of this flag allows boat operators to navigate responsibly, ensuring they do not inadvertently endanger the diver's safety. When observing this flag, it is essential for boaters to slow down and remain vigilant to ensure that the diver can surface safely without interference from passing vessels. This practice promotes safety for everyone involved in recreational boating activities.
