This study examined the relationship between stress and indirect aggression on driving behaviours. These variables were investigated as there was lack of research to examine this. Gender, and age were also examined in other analyses. A total of 84 participants completed the questionnaire and results of the questionnaires were investigated. The study was a cross-sectional, correlational study, which used survey research to examine the hypotheses. The results of a Pearson’s r correlation determined no significant result of the relationship between stress and indirect aggression on driving behaviours. Of the two independent samples T-tests that were run, one was found to be partially significant, with use of malicious humour (a sub-scale of indirect aggression) being identified to be higher in males than in females.
