Background: Road accident statistics has been seen increasing over the years despite numerous efforts made by the authorities. Human factors have contributed 90% of accident occurrence with risky driving behavior being one of the significant human factors that can be further explained through norms. This review paper aimed to investigate the relationship between norms and drivers’ risky driving behavior. Methods: A systematic review process was conducted through four academic databases namely Scopus, Wiley Online Library, Emerald and Web of Science of no limitation for date. Overall, 3443 titles were identified and after several screening and reviewing processes, only 27 studies were included. Results: The results of the review demonstrated mixed findings between subjective norm and risky driving behavior, whereas the relationship between group norm, moral norm, injunctive norm, descriptive norm and risky driving behavior were observed significant. Conclusion: Appropriate educational awareness is required to educate the society in practicing good norms for mutual benefit of the society. Parents also need to set a good example for their children by abiding the traffic rules and regulation.

Road accident statistics has been reported increasing over the years and become one of the significant death contributors worldwide. In response towards this issue, appropriate countermeasures need to be outlined. Proposing a preventive plan requires comprehensive understanding on factors behind the occurrence of road accident. Therefore, this review paper aimed at investigating the factors behind the occurrence of road accident focusing on the technical factors. A review over five academic databases such as Emerald, ScienceDirect, Scopus, Web of Science and Wiley Online Library has been conducted leading towards an overall finding of 2462 related records. After screening and reviewing the records, only 38 studies were included. The result of the review indicated several technical factors in terms of road and vehicle faulty toward the occurrence of road accident.

Human factors specifically, perceived behavioural control (PBC) is among the accident causation factors leading to risky driving behaviour among young drivers. Therefore, this paper aims to investigate the relationship between PBC and young drivers' risky driving behaviour, PBC and accident involvement as well as the mediating role of risky driving behaviour to mediate the relationship between the PBC and accident involvement. The sample of this study involved active young drivers aged between 18 and 25, possess valid driving license, with at least six months of driving experience and have been involved in a road accident for the past 12 months. Results showed a significant relationship between PBC and young drivers' risky driving behaviour as well as the PBC and accident involvement. Moreover, risky driving behaviour was proved to mediate the relationship between PBC and accident involvement.
