An electronic device employed in vehicles, such as automobiles, to ascertain whether the vehicle has stopped at a stop point, such as a stop sign. The operation of the alert device is that it monitors the status of the vehicle's speed or wheel sensor (that it is outputting or not) and if a minimum pulse rate is present, then the vehicle is in motion. A further conclusion can be reasoned is that if there has been no pulse activity over a finite period of time that the vehicle is stopped. The alert device monitors a pulse derived voltage to determine that the vehicle has fully stopped. When the device has detected that the vehicle has come to a full stop an approximately one second tone or chime, and or a visual annunciation is generated and if enabled declare that the vehicle has come to a stop. The alert device also signals when vehicle motion initially occurs by a different tone and flash. The alert device automatically resets for the next stop or initial vehicle movement notification. The alert device facilitates compliance with the law.
