1. An automotive recorder for use with a motor vehicle comprising:

  • one or more sensors adapted to transmit a signal indicative of a safety related vehicle operation variable, one of said one or more sensors being adapted to transmit a signal indicative of vehicle speed;

    a processor having one or more inputs, a timer, an operator alerting output, and an information output, the one or more processor inputs being coupled responsively to said one or more sensors;

    an indicator coupled responsively to the operator alerting output of said processor, said indicator being located for easy perception by an operator of the vehicle when the operator alerting output of said processor is energized; and

    a storage unit coupled to the information output of said processor, said storage unit being substantially non volatile and adapted to receive and accumulate information transmitted from the information output of said processor for review by a monitoring authority after an operation episode;

    said processor being adapted to energize the operator alerting output when the signal from one of said sensor exceeds a predetermined value corresponding to a predefined maximum safe vehicle operating condition, the timer being adapted to trigger said processor to automatically and beyond the control of the vehicle operator transmit information from the information output to said storage unit for review by the monitoring authority after the vehicle operation episode when a predetermined time elapses from the time of energization of the operator alerting output and the signal from said sensor has not receded below the predetermined value.
