ABSTRACT A kind of distress sign has a center of two- section shafts with a plurality of resilient ribs to form a structure frame supporting the canvas sheet cover of pyramid shape; every face of the pyramid canvas sheet cover is painted in triangular warning sign; a sliding slide piece on the lower shaft controls the automatic unfolding and closing of the distress sign; the upper shaft retracts itself in the lower shaft and the canvas sheet cover is folded to three plies thus to effectively lessen the volume and shorten the length of the distress sign.
