In 2013, 632 602 private cars were involved in road crashes, this amounting to 64% of all road crashes on
Malaysian roads. Risk is often used to quantifying the level of road safety whilst exposure is an essential
component of risk measurement. The calculation of VKT (vehicle kilometre travel) in this study using
odometer reading data obtained from automobile manufacturer is used for cars. This average in 2013
was 24,129 kilometres, the highest recorded in Selangor with 28,575 kilometres and the lowest at
16,342 kilometres a year, in Johor. This method is believed to be reliable with a high yielding number
of samples as well as a good representative set of samples for Malaysia.
