Abstract
A motor vehicle operator alerting apparatus is disclosed having a portable housing having a front face and a plurality of fastening clips to attach the apparatus to a support structure within a vehicle. An alert indicator and an alarm indicator are mounted visibly to the front face of the housing, and are used to select an alert time duration and an alarm time duration, respectively. An alert time comparison timer and an alarm time counter compare selected time durations, and energize the alert and alarm indicators, respectively, based upon such comparison. A reset button in communication with both the alarm time counter and the alert time comparison timer is used for de-energizing either the alert indicator or the alarm indicator. An LCD or LED display in communication with the alert time comparison timer displays the time remaining on the alert time comparison timer.
