ABSTRACT:
A safety rear view mirror for vehicles with a restricted field of view is mounted in a preferred position between a standard external rear view mirror on the side of the vehicle opposite the driver's side and the vehicle. The safety rear view mirror or simply safety mirror is positioned to be observed by a driver trainer or driver assistant sealed in a seat adjacent the driver's seat. The position of the safety mirror may be such with respect to the structure of the cab of the vehicle that the safety mirror may not be observed by the driver of the vehicle, hence, that it is only accessible to the driver assistant. In a preferred embodiment the safety mirror includes a safety shield which is disposed between the reflective element of the safety mirror and the driver of the vehicle. The safety shield may be adjusted to an optimum position in which the safety shield restricts the driver's view of the safety mirror in cases where the mirror can not be conveniently mounted to be observable by the driver assistant only. The safety shield protects the driver from receiving a double image of the rear field of view to thereby allow the driver to concentrate on the image observed through the standard external rear view mirror.
