A collapsible post structure having a fragile region that allows the post to collapse when the latter is struck. The post structure includes an elongated anchoring member. The anchoring member having an anchoring member hollow section that extends longitudinally into one longitudinal end thereof and defining an anchoring member inner surface. The post structure also includes an elongated supporting member. The supporting member having a supporting member hollow section that extends longitudinally into one longitudinal end thereof and defining a supporting member inner surface. The post structure further includes a connecting component, the connecting component having a connecting component first section and a connecting component second section. The connecting component first section and the connecting component second section are configured and sized so as to be respectively insertable into the anchoring member hollow section and the supporting member hollow section. The connecting component first section and the connecting component second section respectively define a first friction surface and a second friction surface. The supporting member is frictionally attached in end-to-end relationship to the anchoring component by the connecting component with the first friction surface frictionally contacting the anchoring member inner surface and the second friction surface frictionally contacting the supporting member inner surface. The anchoring member and the supporting member having a greater resistance to impact than the connecting component.
