The aim of this study is to examine whether driver impulsivity predicts aggressive driver behavior and to compare the predictive power of driver impulsivity and general impulsivity towards aggressive driver behavior. A total of 312 drivers, 113 women and 199 men, participated in the study and completed the Demographic Information Form, Driver Anger Expression Inventory, Barrat Impulsivity Scale-Short Form and Impulsive Driver Scale by way of an online link. The hierarchical regression analyses showed that driver dysfunctional impulsivity positively predicted physical anger expression, verbal anger expression and the use of a vehicle to express anger whereas it negatively predicted the adaptive anger expression. Driver functional impulsivity positively predicted physical anger expression, the use of a vehicle to express anger and the adaptive anger expression. The dominance analyses results show that driver dysfunctional impulsivity completely dominates all other driver impulsivity and general impulsivity dimensions for both adaptive and non-adaptive anger expression of drivers. The results of the study emphasize the importance of conceptually addressing impulsivity in future studies and the impact of the measurement tool to be used on the results.
