ABSTRACT OF THE DISCLOSURE A position indicator for automobiles, trucks, and other vehicles includes a numerical display of the vehicle position with respect to an interstate highway by providing a readout of the mile marker location of the vehicle. The display is actuated by an electrical circuit including a presettable up/down counter in which the initial location of the vehicle with respect to a reference marker along the highway is stored. Subsequent vehicle movement increments or decrements the stored count in response to the receipt of vehicle movement pulses from a pulse generator. A calibration circuit is provided to accurately calibrate the system for different vehicles. In one embodiment, a digital keyboard is provided for entering the initial vehicle position information.
