Road traffic accidents (RTAs) are a significant concern in developing countries, such as Bangladesh, resulting in the loss of life or property. To minimize those valuable losses, it’s necessary to gain deeper insights into the associated factors and circumstances of these accidents. Although extensive work has been done on RTA in developed countries, developing countries lag far behind. This study was conducted to bridge the literature gap, identify associated factors and assist authorities in making informed decisions. The main purpose of this research is to identify the age group (young, middle-aged and old) that is most frequently involved in road crashes and the circumstances (crash factors) that influence the crash occurrence of specific age groups from the perspective of a developing country. No research has been conducted to investigate the associations between crash scenarios and driver age groups in a developing country context. The study utilized a Driver Behavioural Questionnaire (DBQ) which had 3000 participants from Rajshahi, Bangladesh. To analyse the relationship between age and crash involvement, this research utilized three models: Poisson Regression, Gamma Regression and Ordered Probit Regression from where the Ordered Probit Model showed the best balance between the model’s complexity and performance. The analysis has revealed that factors such as vehicle speed, lighting conditions, driver occupation, possession of a driving license, improper lane change and driving disability have significant influences on determining age groups involved in crashes. Middle-aged male drivers are more likely to engage in aggressive driving, resulting in higher crash involvement rates. Maintaining smooth driving and careful lane changes greatly decreases crashes. In contrast, sudden speed reductions, disabilities, and inattentiveness during lane changes have led to frequent accidents among middle-aged drivers.
