In Auto Racing, the Dark Blue with Orange Diagonal Stripe Flag is often seen as the opposite to the Blue Flag with
yellow diagonal stripe. Whereas the Blue Flag with yellow diagonal stripe has the yellow stripe going from top right to bottom left, the Dark Blue with Orange Diagonal Stripe Flag has the orange stripe going from top left to bottom right.
This flag is primarily and only seen in FIA-sanctioned championships but IndyCar and NASCAR have it as well but all use the same "Move to the Outside" meaning. The flag does not appear in iRacing.
FIA-sanctioned championships, IndyCar, & NASCAR: Move To the Outside.
