Abstract: A vehicle odometer is provided that records highway mileage traveled by a vehicle. The odometer includes a sensor for selectively activating and deactivating the recording of distance traveled by the vehicle. The sensor may be a speed sensor that is connected to a city odometer and a highway odometer. The sensor activates the city odometer to record distance traveled below a predetermined speed on the city odometer, and deactivates the highway odometer below the predetermined speed. The sensor deactivates the city odometer and activates the highway odometer at speeds above the predetermined speed to record the distance traveled above the predetermined speed on the highway odometer.
