Abstract: A distress sign which is adapted for placement on the upper edge of a vertically movable window of a vehicle. The sign includes a pair of elongate, substantially rigid display panels each having upper and lower marginal edges and end edges. The panels are connected together along their upper marginal edges by a substantially rigid spine panel. A hook entends downwardly from one end of the spine panel and is spaced from the end edges of the panels to provide a slot in which the upper edge of the window is received, and is configured to engage the adjacent end edges of the panels against the surface of the window when the upper edge of the window is received in the slot.
