A diver down flag, or scuba flag, is a flag used on the water to indicate that there is a diver below. In North America it is conventionally red with a white stripe from the upper left corner to the lower right corner. Internationally, the code flag alfa/alpha, which is white and blue, is used to signal that the vessel has a diver down and other vessels should keep well clear at slow speed.

Famous quotes containing the word flag:
“Swift blazing flag of the regiment,
Eagle with crest of red and gold,
These men were born to drill and die.
Point for them the virtue of slaughter,
Make plain to them the excellence of killing
And a field where a thousand corpses lie.”
—Stephen Crane (1871–1900)
