Accidents involving express buses in Malaysia tend to attract a lot of local media attention. Based on statistics from the Royal Malaysia Police (RMP), express buses recorded the highest percentage of total bus crashes during the 3-year period from 2007 to 2009. In this study, data were collected from three different festive seasons in Malaysia with express bus drivers' behaviour being the main focus. Express buses and the journey they took were randomly selected regardless of the express bus company. Data collected from observations were analysed with respect to speeding. Findings of this study reveal that drivers were more likely to exceed the posted speed limit during night-time. Smoking and eating while driving were significantly associated with speeding. The study suggests that further efforts aimed at reducing risky bus driver behaviour demand critical consideration and actions from relevant enforcement agencies and stakeholders. In addition, express bus operators are encouraged to monitor the risky driving behaviour of drivers using suitable monitoring system.
