The main objective of this study is to investigate the possible influencefactors on driving skills and positive driving behaviors via data collected from self-reported instruments. A self-reported questionnaire survey was conducted in a sample of 683 licensed drivers and a total of 532 questionnaires were completed and analyzed in this study. Driving skills, measured by a 28-item driver skill inventory (DSI), are grouped into a three-factor structure, containing basic skills, advanced skills, and safety motives. Positive driving behaviors, assessed by a 13-item driver behavior questionnaire (DBQ), are also classified into three factors, namely facilitatingsmooth driving, taking care of other road users, and being polite. Rasch model is applied to measuring the ability of respondents and the difficulty of items regarding driving skills and positive driving behaviors. It is found that respondents had a higher propensity to endorse their driving skills than that to positive driving behaviors. Experienced drivers had moreconfidence in their driving skills. The results of multiple regression analysis reveal that respondents with lower scores on safety motives and higher driving speeds had greater likelihood of involving in traffic accidents and committing traffic offences.
