Why Do People Get Angry While Driving? The Qualitative Study for Establishing A New Questionnaire

Anger on the road is a mechanical manifestation of hate and disapproval of an individual or a circumstance [1]. However, angriness while driving can undermine one’s performance as a driver and he or she may hurt people physiologically and psychologically. This paper develops a new measure to quantify level of angriness that they experience while driving. Qualitative investigation is carried out with the help of interviews to identify various factors those may predict the degree of anger drivers experience during the process of driving. Reliability and validity of the instrument are reported as well. The study identifies four distinctive dimensions of anger while driving.
