To facilitate road-side parking, a vehicle's dampers (2) are adapted to perform a second function, in the parking mode, in order to bounce the vehicle on its tyres by converting the vehicle's dampers (2) into hydraulic rams to produce vertical acceleration. Spring loaded, telescopic, struts, pivoted to the underside of the vehicle's body are lowered diagonally and, as the vehicle descends in the bounce cycle the struts grip the road surface and push the vehicle horizontally while it is intermittently airborne. The piston rod (16) of the damper (2) is composed of two coaxial pipes (50, 56) and conveys hydraulic pressure fluid sequentially to and from the damper's lower (54) and upper chambers (56). The escape holes, which control the passage of fluid through the piston (14) in the travel mode of operation, are automatically blocked in the parking mode.
