ABSTRACT OF THE DISCLOSURE A self-erecting highway guide post for insertion in the ground is constructed in the form of a resilient plastic channel having a substantially flat center surface flanked on either side by a pair of flat side portions which are joined at an obtuse angle to the center portion by curved surfaces. A second, arcuately cross-sectioned channel is attached by fasteners through the center portions of each channel to the rear of the first channel. The rear, concave surface of the arcuate channel is directed toward the rear surface of the first channel and lies within its side portions. Such a configuration results in a self-erecting highway guide post when one end is imbedded in the ground to denote the margin of a highway. When the post is struck the curved portions flatten allowing the post to bend when run over by a vehicle and to recurve once the vehicle passes to re-erect the post. The self-erecting post may include features including integrally constructed barbs or holes to prevent removal of the channel once inserted in the ground, reflective elements attached to the face of the channel such as reflective tape, construction from a thermo-plastic poly- carbonate resin, and a construction in which the curved portions joining the sides to the central portion are uniformly curved. Other embodiments may omit the second arcuately cross-sectioned channel or may be of the two member con- struction with the first channel being arcuately cross-sectioned.
