Summary
This study investigates the prevalence and determinants of driver anger among car drivers in Batu Pahat, Johor, Malaysia, a region identified as having the highest number of road accidents in the state. Motivated by the link between uncontrolled anger, aggressive driving behaviors, and traffic crashes, the research aims to identify specific situational factors that provoke anger using the Driver Anger Scale (DAS) and to evaluate the relationship between these factors and overall driver anger levels. The researchers employed a cross-sectional survey design, distributing questionnaires to 250 randomly selected car drivers between March and May 2015. The instrument, validated with a Cronbach’s Alpha of 0.907, collected demographic data, driving history, and ratings of anger provocation across six DAS subscales: discourtesy, hostile gestures, traffic obstruction, slow driving, police presence, and illegal driving. Data were analyzed using SPSS version 20.0, utilizing descriptive statistics, chi-square tests, correlation analysis, and multiple regression analysis. The findings indicate that "discourtesy" was the most dominant factor contributing to driver anger, with specific triggers such as failing to signal lane changes or taking reserved parking spots eliciting the highest anger ratings. Conversely, "police presence" was the least provoking factor. Chi-square tests revealed significant associations between higher anger levels and younger age, less driving experience, longer driving distances, prior involvement in traffic crashes, and history of receiving traffic tickets. Correlation analysis confirmed strong, significant positive relationships between driver anger and four of the six DAS factors: discourtesy, hostile gestures, slow driving, and traffic obstruction. Multiple regression analysis further established that discourtesy exerted the greatest influence on driver anger (β = .412, p < .05), followed by traffic obstruction, while the model explained 25% of the variance in driver anger. The study concludes that discourteous behavior is the primary catalyst for driver anger, which in turn predisposes drivers to aggressive and risky behaviors. The authors recommend that authorities implement action plans to curb discourteous driving, improve driver training curricula to foster better attitudes, and promote defensive driving skills. Additionally, mass media campaigns are suggested to advocate for tolerance and highlight the negative impacts of aggressive driving, thereby addressing the root causes of road rage and improving overall road safety.
