A tactile indicator for motor vehicles is proposed which in conjunction with a distance alarm device gives an appropriate signal to the driver when a minimum distance to the vehicle in front is not maintained. As a tactile signal, vibrations of the vehicle or of its parts such as steering wheel or driver seat are proposed. The vibrations are caused, for example, by intermittent cutting out of the engine ignition.
