Driving anger,emotional and instrumental aggressiveness,and impulsiveness in the prediction of aggressive and transgressive driving

The present study investigates the potential contribution of three predictors of aggressive and transgressive behaviors on the road: driving anger, impulsiveness and aggressiveness. A total of 455 participants (laypersons), of all age and gender, filled self-reported measures evaluating driving anger, impulsiveness, two forms of aggressiveness (instrumental and emotional forms), driving behaviors and aggressive and transgressive behaviors. Main results indicate: (1) a significant gender effect for almost all variables; (2) gender was involved in the prediction of Lapses and Errors; (3) driving anger, impulsiveness and aggressiveness were involved in a complementary manner in the prediction of aggressive and transgressive driving; (4) Aggressiveness and Impeded Progress were the best predictors of violations and aggressive violations. Results support that transgressive driving behaviors are relevant indicators of aggressive driving.
