A combination speedometer/odometer apparatus for displaying either the speed of a vehicle or the distance a vehicle has traveled, and including a speed pick-up attached to the vehicle for developing a first voltage signal having voltage spikes occurring at a frequency proportional to the speed of the vehicle; a pulse generator which develops a voltage pulse in response to each spike, the pulses having a predetermined duration; a signal generator controlled by the voltage pulses which develops a speed signal and a distance signal both having bursts of high-frequency signal, the number of bursts in the speed signal being proportional to the speed of the vehicle and the number of bursts in the distance signal being proportional to the total distance the vehicle has traveled; a first counter for counting the cycles of the speed signal, the counter initiating its count in response to a reset signal; a synchronizer for developing the reset signal a predetermined period of time after the occurrence of one of the voltage pulses; a second counter for counting the cycles of the distance signal; and a display for visually displaying the count of the first or second counter, thus indicating speed of the vehicle or the distance the vehicle has traveled.
