Abstract
A reflection road stud comprising a body member attached or attachable to a road surface without excavation thereof, a reflector assembly mounted in or integral with the body member and comprising at least one reflex reflecting surface, means for wiping the reflecting surface when a road wheel of a vehicle passes over the road stud, and a region of resilient deformability disposed between the reflector assembly and the road surface when the road stud is attached thereto, whereby, when a road wheel of a vehicle passes over the road stud the reflector assembly is depressed towards the road surface and returns substantially to its initial position when the depressing force of the road wheel is removed.
