A metal anchor tube is driven into the ground or blacktop and defines a cavity which receives the lower end portion of an elongated cylindrical flexible marking tube extruded from a resilient plastics material. The upper end portion of the marking tube supports a light reflecting member which may be in the form of a reflective sheet located within the marking tube and visible through an opening or window within the tube. In one embodiment, the lower end portion of the marking tube is releasably coupled to the anchor tube by an internal wedge plug which compresses the marking tube against the anchor tube and is inserted and removed by means of a tool. In another embodiment, the releasable coupling is formed by an anchor tube having tabs which project inwardly into corresponding holes within the flexible marking tube. A flexible plastic reinforcing tube extends within the marking tube and assures the self-erecting of the marking tube to an upright vertical position after the marking tube has been impacted and bent by a motor vehicle accidentally passing over the tube.

A self-erecting roadway marking post comprising an elongated flexible and resilient marking tube of plastics material and having an annular cross-sectional configuration, said marking tube having a lower end portion adapted to project downwardly into a hole defined within the ground and an upper portion projecting substantially above the ground, means no said upper portion of said marking tube for reflecting light, said upper portion of said marking tube being capable of bending above the ground through an angle of ninety degrees in response to being accidentally impacted by a motor vehicle, an elongated tube erecting member of resilient flexible material, said erecting member extending with said upper and lower portions of said marking tube and being completely surrounded by said marking tube, said erecting member having an intermediate portion disposed for bending within said marking tube when impacted by the motor vehicle, and said erecting member and the surrounding said marking tube being cooperatively effective to provide said marking post with a substantial number of self-erections in response to vehicle impacts on said marking post while minimizing the damage of said marking post.
