Road crashes in Malaysia in year 2006 stand at 341,232. This results in 6,287 deaths among road users giving an index of 23.5 road fatalities per 100,000 inhabitants. One of the possible reasons for the high number of crashes and injuries in results is due to beating traffic lights. Thus there is a need to look at alarming area. Therefore a cross-sectional study was conducted in Selangor, Malaysia to identify road traffic-light violations. Traffic light violations is believed to be rising and resulted in 136 motorists killed and 155 were injured in 2002. The near-miss incidents could be higher as they go unreported. This study was conducted through observations from 14 December 2005 till 22 January 2006. Four locations were chosen to represent Selangor: Kajang, Kelang, Utara Subang Jaya (USJ) and Bangi. During this 5-week period a total of 3,471 vehicles were observed. Data was analyzed using SPSS version 13.0. A bivariate analysis (logistic regression) was applied to determine any relationship between traffic light violation and three identified variables. Results showed the traffic light violation has a relationship with all three factors: camera enforcement, types of vehicles (two-wheel vehicles or four-wheel vehicles) and types of traffic lights (timer or normal).
