Abstract
Driving is one of the most complex tasks that humans perform on a regular basis, placing significant demands on human perceptual, cognitive, and motor capabilities, so age-related declines in these capabilities negatively affect driving performance. Although older adults create a risk on the road because of their high crash rates, it is important to note that not all older drivers have impaired driving performance or high crash risk. Thus researchers have developed test batteries to identify at-risk older drivers. The literature pertaining to the development and testing of at-risk driver assessment tools, including major assessment tools and evidence supporting their use is reviewed.
