The invention relates to a device reducing speed of vehicles travelling on a roadway, formed by at least one strip of flexible material, rubber or other similar material, made up of several hollow chambers which are interconnected by a calibrated conduit which enables the controlled passage of the fluid filling said chambers from that flattened by the wheel of the vehicle towards the adjacent chamber. The fluid contained therein is a non-Newtonian fluid offering the higher viscosity, the higher the stress gradient applied thereto is, the fluid itself acting as means for controlling the resistance to deformation of the strip as the higher is the speed of impact of the vehicle in said strip.
