Color-specificity to enhance identification of rear lights.
30 male and 13 female licensed drivers were given a static reaction-time test for Donders Type B reactions to the onset of automotive rear lights. The lights were displayed as by conventional systems and by a new color-specific method referred to as the "Red Light Means Stop approach." When subjects were instructed to regard all red colored light as brake-signal light, both incidence of identification error and reaction time decreased. Results support the hypothesis that addition of color specificity to rear lighting might prevent some rear-end collisions which occur under adverse driving circumstances.
