Brief study of
MORTH Specifications
Ministry of Road Transport and Highways (India).
Introduction:
The Ministry of Road Transport and Highways, a ministry of the Government of India, is the
apex body for formulation and administration of the rules, regulations and laws relating to road
transport, and transport research, in order to increase the mobility and efficiency of the road
transport system in India. Road transport is a critical infrastructure for economic development
of the country. It influences the pace, structure and pattern of development. In India, roads are
used to transport over 60% of the total goods and 85% of the passenger traffic. Hence,
development of this sector is of paramount importance for the India and accounts for a
significant part in the budget
Creation:
The Department of War Transport was formed in July, 1942, by the bifurcation of the then
Department of Communications into two Departments:
i) Department of Posts
ii) Department of War Transport.
Functions:
The functions allocated to the Department of War Transport include Major Ports, Railways
Priorities, utilization of road and water transport, Petrol rationing and Producer Gas. Broadly
speaking, the functions of the War Transport Department were to coordinate the demands for
transport in war time, Coastal Shipping and the administration and development of major ports.
Later, the planning of export was undertaken as a corollary to the Departments control of
transport priorities also.
Changes made over years:
 1957: Department of War Transport was renamed as Ministry of Transport &
Communications and Department of transport was placed under it.
 1966: On 25 January, under President's order the Department of Transport, Shipping &
Tourism was placed under Ministry of Transport and Aviation.

 1967: On 13 March, the Ministry of Transport and Aviation was bifurcated into
Ministry of Shipping and Transport and the Ministry of Tourism and Civil Aviation.
 1985: On 25 September, during reorganisation the Ministry of Transport and Shipping
became the Department of Surface Transport under the Ministry of Transport.
 1986: On 22 October, the Department of Surface Transport under Ministry of Transport
was renamed as Ministry of Surface Transport.
 1999: On 15 October, Ministry of Surface Transport was subsequently re-organized
into departments, namely Department of Shipping and Department of Road Transport
and Highways.
 2000: On 17 November, the Ministry of Surface Transport was bifurcated into two
Ministries namely Ministry of Road Transport and Highways and Ministry of Shipping.
