Abstract
A systematic analysis was made of the visual and auditory requirements of automobile and motorcycle driving which resulted in the identification of visual performance parameters that appear important to driving but that are not currently considered in the visual screening of driver license applicants. These include such parameters as perception of motion, dynamic performance of the total visual system, visual performance under low levels of illumination or in the presence of glare, and useful peripheral vision. The analysis did not identify similar requirements of auditory performance.
