Abstract

Anger and driver aggression increase crash risk. However, how these manifest according to the purpose of the journey (work vs personal) and the unique relationships between sources of anger and aggressive expressions of that anger is under-researched. The current study examined the relationships between different types of anger and aggression, recent crashes and infringements between drivers who drive mainly for work with those who drive mainly for personal reasons. Participants (N = 630) completed an online questionnaire reporting their driving anger tendencies across situations of travel delays, danger and hostility from others, frequency of aggressive driving (using the vehicle, verbal or physical) and crash and infringements in the previous year. Drivers were classified as work or personal drivers based on the percentage of the time they drove for each reason. Relationships between anger sources and aggression types were examined using Structural Equation Modelling, comparing models between the two groups. The relationships between aggression and safety outcomes were explored using Mann-Whitney U tests. The relationships between anger and aggression were similar across work and personal drivers. However, some group differences in the situations that contributed to anger and aggression were identified. Aggression was more frequent for drivers who drove mainly for work and had received a traffic violation, compared to those who had not received a traffic violation. These findings can inform the development of targeted interventions to manage the triggers of anger and aggression. Interventions are likely to impact work and personal drivers; thus, could target employers and road transport authorities.
