Road traffic accidents involving motorcyclists have increased steadily over the years in Malaysia. The causation of road traffic accidents is normally related to individual and environment factors. Therefore, this review aims to identify human risk factors for road traffic accidents among motorcyclists in Malaysia. We conducted a systematic review on the following electronic databases: Scopus, Wiley Online Library, Emerald, Web of Science, Google Scholar and Malaysian Institute of Road Safety Research (MIROS) from 1970-2017. A total of 1369 titles were identified and following the screening and review processes (i.e. title screening, abstract screening and full text reviewed), only four studies were included.  Results showed that motorcyclists’ traffic violation behavior is the main risk factor that contributes to road traffic accidents. This review paper helps to provide an understanding of the role of human factor contributing to road traffic accidents in Malaysia. It is suggested that an effective road safety campaigns could help in reducing the number of road traffic accidents in the future. More studies are needed to provide a better insight on the risk factors that lead to road traffic accidents.
