yellow flag
Track hazard signal
Yellow flag has meanings unified by caution or warning.
In racing, a yellow flag signals drivers to slow down due to hazards ahead.
In medicine and maritime contexts, a yellow flag historically indicated quarantine—a ship flying one carried disease or required inspection.
In relationships, a yellow flag is a warning sign less severe than a red flag: His temper isn't a dealbreaker, but it's a yellow flag.
Yellow flag is also a common name for certain irises that grow in wetlands.
