A road vehicle is disclosed having a bumper assembly fitted to the rear end of the vehicle. The bumper assembly includes a beam extending across the rear end of the vehicle and supported by an arm from the vehicle so that the beam is displaceable from a rest position in a direction towards or beneath the vehicle in the event of contact with an obstacle. The beam is provided with a spring device for biasing it towards its rest position and the spring device is directly linked to a device for signalling displacement of the beam
