Aggressive driving and road rage are increasingly leading to Motor
Vehicle Collisions (MVC), especially in the developing countries. Considering that
malevolent personality characteristics, such as dark triad (narcissism,
Machiavellianism, and psychopathy) create a tendency for vengeful and aggressive
driving, we examined the power of personality variables in predicting MVC.
Specifically, using Contextual Mediated Model (Sümer, 2003), we tested a double
mediation model in which driving anger and vengeance mediate the relationships
between personality characteristics (Big Five Traits and Dark Triad) and driving
violations, and in turn, driving violations mediate the link between driving
anger/vengeance and risky driving outcomes (MVC and traffic tickets). Turkish
drivers (N = 485, female = %51) completed the measures of personality, aberrant
driving behaviors, vengeance, and driving anger. Results of path analyses revealed
that whereas narcissism and neuroticism are the critical predictors for aggressive
driving Machiavellianism is the strongest predictor of driving vengeance.
Moreover, Machiavellianism both directly and indirectly via driving vengeance and
violations predicted MVC. Personality variables and mediating variables explained
21% and 26% of the variance in MVC and traffic tickets, respectively, values much
higher than those previously reported in the past research. Findings have critical
implications for the assessment of aggressive drivers and potential for road rage.
