Different research traditions have attempted to explain individual differences in risky driving behavior and traffic accident involvement. This study was designed to improve a model for risky driving attitudes (RDA) and to understand the mechanisms underlying drivers' risktaking behavior in traffic. The questionnaire used in this study was composed of "the driver's behavior" questionnaire, improved by Reason, Manstead, Stradling, Baxter, and Campbell, (1990), and "the scales measuring attitudes and behavior" questionnaire, improved by Ulleberg and Rundmo (2003). The questionnaire survey was carried out among 600 drivers. Analysis revealed that risky drivers' attitudes are related to factors such as obedience to speed rules, risk-taking tendency in traffic and positive attitudes towards traffic.
