| Summary: | Previous research about subjective driving skills has revealed that drivers, especially younger males, tend to rate their driving skills more highly than those of the average driver. This study examines the accuracy of Japanese novice drivers' self-evaluation of their driving skills by comparing their self-assessments with assessments made by a driving examiner. We also examined the effects of gender and age on the accuracy of driver self-evaluation of their skills.
A sample of Japanese driving test candidates (n=2021) completed a self-assessment using a 5-point scale applied to 19 items. The candidates completed the assessment shortly after passing their practical driving test conducted at a driving school. Their performance was also assessed by an examiner who used the same scale. The comparison between self-assessment and examiner-assessment revealed that around 40% of Japanese driving school students made a realistic assessment of their skills. With regard to the gender differences, although males displayed higher levels of overconfidence than females did, the differences were not as large as earlier studies with questionnaires had suggested. Furthermore, the effect of age on the accuracy of novice drivers' skill assessment was found to be relatively small. Our findings, which are based on a comparison of subjective assessments of driving skills between examiners and novices, instead of a questionable method which relies on a comparison with a hypothetical average driver, suggest that the majority of candidates in fact do not overrate their own skills. These results were discussed from the viewpoint of the driver education system and compared to other European research using the same framework.
