The effects of motor impulsiveness and optimism bias on risky driving behavior in Chinese urban areas

The present study investigated the influence of motor impulsiveness and optimism bias on self-reported risky driving behavior. Two components of risky driving behavior, angry driving and traffic violation for convenience were identified. Structural Equation Modeling results supported motor impulsiveness directly predicting angry driving and traffic violation for convenience, with optimism bias partially mediating the relationship between motor impulsiveness and angry driving. Traffic violation for convenience was significantly related to safety performance. Practical implications and safety interventions were discussed.
