| Summary: | Road characteristic is one of the main contributing factors for fatality to the motorcycle when involve in HGV crash. In particular, the studies related to HGV and motorcycle crashes affecting by the road characteristics have been relatively limited. This article provides eight road characteristics that were identified in the crash between HGV and motorcycle. The purpose of this article is to examine the severity of a motorcycle crash when it is engaged in the HGV crash. This study intends to evaluate the road characteristics which are significantly giving effect to the fatal crashes between HGV and motorcycle. The data acquired from RMP crash database for the past three years was cleaned and filtered then analysed statistically through descriptive and simple logistic regression analysis using SPSS software. The result reveals that eight main risk factors of road characteristics are associated to contributing to HGV-motorcycle crash fatality. Descriptively, fatality occurrence is higher in unexpected road characteristic as per common assumption; more fatalities in straight road as compared to other road geometry characteristic. Furthermore, not every characteristic is statistically significant towards the probability of fatality to occur in HGV-motorcycle crash, such as the bend and the sloppy road. Hence, findings in this study are expected to provide a new insight in evaluating the road characteristics factor affecting the HGV-motorcycle crash fatality. © 2024, Semarak Ilmu Publishing.
