Due to the operating speeds almost the same as the speed limit of the main carriageways itself, T. H. Law et al. (2005) suggest that the minimum width of the segregated motorcycle lane at the Federal Highway should be set at 3.81 m. However, the average width the existing segregated motorcycle lanes, such as that which is located on the Federal Highway, is only two meters wide. The width of the motorcycle lane is too narrow for bigger motorcycles, as well as for the purpose of overtaking.
