Today the red and white flag is so strictly associated with scuba diving that it is also used to indicate a place where there are services for divers, for example stores selling or renting diving equipment or scuba service stations. It may be seen on the windows or bumpers of cars belonging to divers.
Code flag alfa/alpha also represents the letter 'A' in signalling.
Rock band Van Halen used the red and white flag as the cover art of their 1982 album Diver Down.
The Webcomic Alpha Flag features both the American and International variant of the diver down flag among other signal flags as part of its plot device.
