A data processing device is disclosed which includes automatic screen blanking and keyboard deactivation during those times whenever the associated vehicle in which the data device is installed is detected as being in motion. Further, when a message is received while the vehicle is in motion and the display screen blanked, an audible signal is generated to announce the receipt of such received message as well as providing an indication to the user/driver of the vehicle as to the nature of such received call. All keyboard interrupts generated during the time the vehicle is in motion and the visual display blanked are simply ignored.
