A vertical highway marker is provided having a mounting base, a marker post and a mounting bracket. The mounting bracket secures the marker post to the mounting base. The highway marker includes a flexible region which bends so that the marker post will rotate relative to the mounting base when the marker post is impacted by a vehicle. The mounting base is a low-profile, square rubber pad which may be driven over by a vehicle without disturbing the driver's control of the vehicle. A resilient member is disposed proximate to the flexible region of the highway marker for bending with and stiffening the flexible region. Blocking members extend on forward and rearward sides of the resilient member and the flexible region for limiting a range of bending over which the resilient member bends with the flexible region, such that the stresses within the resilient member are not substantially greater than the yield strength of the resilient member. In a preferred embodiment, two strips of the elastomeric belting are used to provide the forward and rearward blocking members. The blocking members are secured on one end to the mounting base and have opposite ends which extend upward on the forward and rearward sides of the marker post.

[ What is claimed is:] [1.] In a highway marker of the type having a mounting base, a marker post and a mounting bracket securing the marker post to the mounting base, one of the mounting base, the marker post and the mounting bracket being flexible for bending in a flexible region to rotate the marker post relative to the mounting base in response to forces acting on an outward end of the marker post, the improvement comprising:a resilient member disposed proximate to the flexible region for bending with and stiffening the flexible region of the one of the mounting base, the marker post and the mounting bracket which is flexible and bends in response to the forces;a blocking member extending on at least a rearward side of the resilient member for limiting a range of bending over which the resilient member bends with the flexible region of the one of the mounting base, the marker post and the mounting bracket;wherein the blocking member limits the range of bending of the resilient member to determine a minimum radius of curvature for the resilient member such that stresses within the resilient member are not substantially greater than a yield strength of the resilient member; andwherein the blocking member comprises an elastomeric strip mounted aside of the flexible region of the one of the mounting base, marker post and mounting bracket.
