An improved sign and sign stand assembly is disclosed wherein the sign stand includes means for mounting the sign on a frame member of the stand. The frame member includes means for permitting the sign to laterally pivot or swing under side-wind loads in order to allow a resilient portion of the frame member to deflect generally along a predetermined plane, thereby substantially preventing the sign and stand assembly from tipping over. Means are also provided for displaying warning flags or other warning devices on said sign and stand assembly without restricting or impeding such laterally pivoting or swinging of the sign.
