Transportation in Malaysia started to develop during British colonial rule, and the country's transport network is now diverse and developed. Malaysia's road network is extensive, covering 290,099.38 kilometres, including 2,016.05 km of expressways (in 2021). The main highway of the country extends over 800 km, reaching the Thai border from Singapore. Peninsular Malaysia has an extensive road network, whilst the road system in East Malaysia is not as well-developed. The main modes of transport in Peninsular Malaysia include buses, trains, cars and to an extent, commercial travel on airplanes.
Malaysia has six international airports. The official airline of Malaysia is Malaysia Airlines, providing international and domestic air service alongside two other carriers. Most of the major cities are connected by air routes. The railway system is state-run, and covers a total of 1,849 km. Popular within the cities are commuter rail and rapid transit, which reduces the traffic load on other systems, and is considered safe, comfortable and reliable.
