Can High-Risk Older Drivers Be Identified Through Performance-Based Measures in a Department of Motor Vehicles Setting?

Older drivers are a rapidly growing segment of the driving population and are overly represented in crashes and fatalities per mile driven. Thus, identifying older drivers at risk is becoming more and more vital in order to avoid dramatic increases in traffic fatalities over the coming decades. This article reports on a prospective cohort study undertaken to evaluate the relationship between performance-based risk factors and subsequent at-fault motor vehicle collision (MVC) involvement in a cohort of older drivers. The study included 2,114 individuals aged 55 to 96; the authors analyzed data from 1,910 individuals recruited through Motor Vehicle Administration (MVA) field sites. Measurements included the Gross Impairment Screening Battery that covers Rapid Pace Walk, Head/Neck Rotation, Foot Tap, Arm Reach, Cued Recall, Symbol Scan, Visual Closure subtest of the Motor Free Visual Perception Test (MVPT), Delayed Recall, and the Trail Making Test; the Useful Field of View (UFOVs); a Mobility Questionnaire; and information on MVC occurrence. The results showed that, in drivers aged 55 and older with intact vision, age, sex, history of falls, and poorer cognitive performance predicted future at-fault MVC involvement. After adjusting for annual mileage, participants aged 78 and older were 2.11 as more likely to be involved in an at-fault MVC. Older adults, men, and individuals with a history of falls were more likely to be involved in subsequent at-fault MVCs. The authors conclude that high-risk older drivers can be identified through brief, performance-based measures, administered in the standard MVA setting.
