ABSTRACT:
A highway marker having a base inserted into a hole formed in highway pavement so that the upper surface of the base is below the surface of the pavement and an integral upstanding flexible tab which projects above the surface of the highway. A light reflecting member is secured on one side of the tab for reflecting light directed against the member to indicate the location of the marker. The height of the tab is less than the distance from the base of the tab to the side of the marker facing away from the light reflecting member so that when a vehicle is driven over the marker the tab is bent down against the top of the base below the surface of the pavement and flexes back to the upright position upon passage of the vehicle. The surface of the light reflecting member may be angled back at a 4.degree. angle with respect to the vertical to improve reflection back to drivers of vehicles approaching the marker.
