Samenvatting The objective of this study was to evaluate the ability to predict on?road driving in cognitively impaired older drivers. Participants were drivers with cognitive impairment (Mini-Mental State Examination score < 26, N = 43, mean age 74). Measurements were The Roadwise Review, a hazard perception test (HPT), several vision tests, and a standardized 18-km driving assessment. Results showed that the best prediction of passing or failing the on-road test was a combination of the HPT, leg strength, visual acuity, visual search and working memory, and number of medications taken (Nagelkerke coefficient of determination = 0.40). The sensitivity of the model was 71%, and the specificity was 75%. The study concludes that further research is required to determine how these tests may be used or combined with other data (e.g., medical history) to assess fitness to drive of cognitively impaired older drivers.
