1. In combination:

  • a vehicle including;

    a front end;

    a rear end; and

    a rear viewing device obscuring a portion of an operator'"'"'s forward view;

    a vehicle operator performance monitor comprising;

    a housing including first image sensing means having an optical axis;

    said first image sensing means for sensing optical images and for producing a first image signal representing the sensed images;

    an event detection circuit connected to said housing producing a trigger signal responsive to detection of a predetermined triggering event;

    a playback circuit connected to said housing including;

    a persistent memory device an output port;

    operator control means for producing a control signal responsive to operator activation; and

    a programmed computer connected to said persistent memory, to said output port, and to said operator control means; and

    a capture circuit connected to said first image sensing means for receiving and capturing the first image signal therefrom, connected to said event detection circuit for terminating capture of the first image signal within a predetermined time period upon receipt of a trigger signal therefrom, and connected to said persistent memory device for loading the captured first image signal therein; and

    mounting means for mounting said monitor to said vehicle such that said monitor is disposed substantially within the portion of the operator'"'"'s view obscured by said rear viewing device and said optical axis is directed for receiving desired images;

    wherein said programmed computer is programmed for downloading the first image signal from said persistent memory device to said output port responsive to a control signal from said operator control means; and

    wherein said playback circuit is readily removable from said housing mounted in said vehicle for removal from said vehicle to a remote location for playback.
