A motor vehicle controls operation of a mobile electronic device and includes a fingerprint sensor which scans a driver's fingerprint and produces a first electronic representation of the driver's fingerprint. A wireless transceiver receives from the mobile electronic device a first air-borne signal including a second electronic representation of the driver's fingerprint. An electronic processor determines whether the vehicle is in motion, compares the first electronic representation of the driver's fingerprint to the second electronic representation of the driver's fingerprint, and causes the transceiver to transmit a second air-borne signal to the mobile electronic device. The second air-borne signal instructs the mobile electronic device to disable itself. The second air-borne signal is transmitted only if the processor determines that the vehicle is in motion and ascertains as a result of the comparison that the first electronic representation of the driver's fingerprint matches the second electronic representation of the driver's fingerprint.
