A device to be used in connection with an automotive vehicle for indicating rates of acceleration above pre-set thresholds so that the vehicle operator may change such rate in a fashion to reduce fuel consumption. The device includes a box-like housing containing a mercury switch having two electrodes located at a first end thereof and which are adapted to be bridged when the mercury mass moves under the influence of acceleration forces. These electrodes are connected in a series circuit with a source of electrical potential and an indicator means such that a signal is given when and if the vehicle is accelerated at a rate above an adjustable, pre-set level.
