Abstract
A study is presented that explored the role of macho personality, age, and power of car as predictors of aggressive driving behavior. A total of 154 male motorists completed two subscales of the Hypermasculinity Inventory as a measure of macho personality and self‐reports of aggressive driving behavior based on the Driver Behaviour Questionnaire. They also provided information about their age, annual mileage, horsepower of their car, and features that had guided their choice of a car. A multiple regression analysis showed that each of the predictors was significantly related to aggressive driving: Younger motorists, those driving powerful cars, and those showing macho personality were significantly more likely to report driving aggression. Together, the three predictors accounted for 35.8% of the variance. In addition, macho men assigned greater importance to speed and sportiness of a car and less importance to safety aspects than nonmacho men. The findings are discussed with reference to individual and situational explanations of driving aggression. Aggr. Behav. 28:21–29, 2002.
