In Singapore, cars and other vehicles drive on the left side of the road, as in neighbouring Malaysia, due to its British colonial history (which led to British driving rules being adopted in India, Australia, New Zealand, and Hong Kong as well). As a result, most vehicles are right-hand drive. However, exemptions have been made to allow foreign vehicles and construction machineries to utilise the roadspace of Singapore. As such, vehicles with left hand drive configurations are required to either be driven with a sign indicating "LEFT-HAND-DRIVE" or towed.
