ABSTRACT:
A portable automobile driver testing unit comprises a cabinet having two side walls which can be swung open and an end wall in which there is a sight opening. In the bottom portion of the cabinet there is a compartment enclosed by a control panel and on the inner face of the cabinet top wall there are mounted relatively moveable elements for testing depth perception. The end wall with the opening is further provided with a pair of headlights, a first group of lights having removable letters and the brightness of which can be controlled by a rheostat, and a plurality of colored lights. A foot pedal assembly is connected to the control panel to be used in conjunction with the colored lights for testing reaction time and the assembly is stored upon the partition within the cabinet when not in use. A person facing the end wall with the opening and lights can be tested for depth perception, night vision, glare recovery, field of vision and simple and complex reaction time. The unit can also be used to test for visual acuity and traffic color recognition.
