<p>A rear underride protection (1) intended for vehicles (2) comprising a bar (10) transversal to the direction of motion of the vehicle (2) and fixed to the vehicle (2), and a movable bar (13) displaceably arranged in the longitudinal direction of the fixed bar (10). At one end the movable bar (13) has a means of attachment (14) to enable fitting of an implement, e.g. in the form of a side-plough (3). The projection of the movable bar (13) can be adjusted at one's option and the sliding motion to which oil is supplied from the forced oil system of the vehicle (2). The hydraulic cylinder actuates the movable bar (13) by a buffer means, the purpose of which is to spare the rear underride protection (1) and implements connected to this great mechanical stresses. When the rear underride protection (1) is not connected to any implement the movable bar (13) is operated to a position where the means of attachment (14) does not project outside the lateral surface of the vehicle (2).
