ABSTRACT OF THE DISCLOSURE A self-cleaning reflective road marker comprises a housing formed of a generally cylindrical portion insertable into the road and a flanged portion for lying on the road surface connected thereto. The housing contains a stud mounted on a rubber hemisphere. The stud contains a circular reflector and the housing contains a circular o-ring located in the flanged portion opposite the reflector. In response to the passing of a tyre over the marker, the stud is depressed and the reflector is wiped clean by the o-ring. On removal of the tyre force, the resilience of the rubber hemisphere forces the stud into its original position and the reflector is further cleaned by the o-ring. The stud consists of two parts connected together, from above by a threaded bolt such that when the marker is fixed in the road the part can be removed to enable removal or replacement of the reflector and the o-ring.
