In this on-road study, it was found that about 25% of older drivers overestimated their driving skills. Overestimators showed poorer on-road driving performances, a higher likelihood of prospective near and minor at-fault accidents, poorer cognitive performances in specific driving-related domains, and reduced annual mileage.
Objectives: Older drivers often show less precise self-ratings with a tendency to overestimate themselves. It is unclear, however, how overestimators differ from underestimators or drivers with adequate self-ratings.Methods: 59 healthy older drivers participated in this on-road study. Besides standardized on-road driving assessment, the study protocol included the collection of neuropsychological and driving-related data as well as different self-ratings. Statistical analyses involved correlations between different subjective and objective ratings as well as statistical comparisons between drivers who overestimated and drivers who adequately rated their on - road driving performance (no drivers underestimated their performance).Results: Despite positive correlations between different self- and expert ratings, our results revealed that 25 % of the participants overestimated their on-road driving skills. Among other things, overestimators showed poorer on-road driving performances, more prospective near and minor at-fault accidents, poorer cognitive perfor- mances in specific driving-related domains and reduced annual mileage.Discussion: Our results suggest that older drivers who overestimate their driving skills show poorer performances within a broad range of skills that directly reflect or are closely related to driving safety. Against the background that an adequate self-assessment is required by German traffic regulations, our findings suggest that over - estimators represent a risk group among the population of older drivers.
