Aggressive driving and its counterpart, road rage, are serious safety problems. Four hundred and fifty-two students and University employees representing a variety of ages (18–70 years old), ethnicities, and driving habits, participated in this study to examine whether gender, age, and traffic congestion correlated to driver anger and aggressive driving. Results indicated that students and employees did not differ on driver anger or aggressive driving, suggesting that past research on students could be generalized to university employees. Driver anger was significantly correlated with aggressive driving and age. Younger drivers were more angered by a variety of driving situations than older drivers. These differences were able to account for a large proportion of the age differences in aggressive driving but did not completely eliminate the importance of age as an independent predictive factor. Exposure to traffic congestion was found to be unrelated to driver anger or aggressive driving tendencies. |
