A signalling device comprises a flag which is attached to a pole. The flag has a first surface (x) and an opposite second surface (y) with a different appearance, and the flag is provided with a fold line (7) over which the flag can be folded. In a first folded position the flag's first surface (x) faces outwards, and in a second folded position, where the flag's surfaces are folded 360 DEG in relation to the first folded position, the flag's second surface (y) faces outwards.
