A guardrail terminal having a number of vertical supporting members fixed into the ground one after the other along the edge of the road; a curved or straight first transverse horizontal retaining member fixed to the vertical supporting members at a given height off the ground, and curving in the horizontal plane so as to extend gradually away from the edge of the road, as of the end of the guardrail; and a curled second transverse horizontal retaining member, which projects from the terminal end of the first transverse horizontal retaining member, curves back in the horizontal plane towards the first transverse horizontal retaining member, and is fixed by its own terminal end to the start end or to an intermediate portion of the first transverse horizontal retaining member, so as to form, together with the first transverse horizontal retaining member, a substantially tear-shaped collapsible annular member.
