ABSTRACT:
An emergency warning traffic sign comprises a conventional stop sign which has been divided vertically in the middle into two sheet portions carrying portions of the message on one face of each of the sheet portions. The sheet portions are connected by a hinge such that a first of the portions may be mounted to a traffic signal post and the second sheet portion may be rotated between a first position in which the message is obscured to a second open message position. A locking bar is attached to the first sheet portion and is pivotally movable across the back of the sign and within its perimeter to lock the sign in both its open and closed positions. In a second embodiment of the invention, another sign carrying a different message is also divided vertically into a third and forth sheet portions and these sheet portions are hingedly connected to each other. The third sheet portion is stationarily mounted to the back of the second sheet portion such that the second sign with its message may be displayed when the first sign is folded and vice versa.
