Reducing the Problems of Nighttime Driving for Older Individuals

Older persons often give up or greatly reduce driving during the hours of darkness. The reason for this is apparently age-related changes in vision that are most noticeable under conditions of low illumination. This paper reviews research that shows how the nighttime visual performance of older drivers can be aided. Improvements discussed involve the detection and legibility of highway signs and the detection and identification of potential hazards such as large trucks.
