A truck driver claimed to fall down a set of metal stairs near a loading dock approximately 90 minutes prior to sunrise. We performed an engineering evaluation of the lighting environment in order to assess whether the exterior lighting was sufficient to see and successfully descend the stairs. Our analysis uncovered the visual effect of one potentially malfunctioning exterior light that was alleged to have contributed to the fall.
