Until 1997, the transport corporation was divided into 21 divisions which were later merged to form 8 divisions. TNSTC along with its subsidiaries, owns 321 depots and five workshops with a combined fleet strength of 21,678 buses. TNSTC also offers contract and tourist services. Every bus owned by the corporation displays a portrait of Tamil poet Thiruvalluvar along with a two-line verse from Thirukkural inside the bus.

The planning commission, in consultation with this ministry, has advised the state government to set up a road transport corporation under the Transport Corporations Act and the matter is under the consideration of the state government. Operation of nationalized transport services through a corporation is favoured so as to achieve railroad coordination, and to ensure operation on business lines. The general policy of the government is to establish corporations and the planning commission have advised that if the state governments want to nationalise the road services, they should form corporations and they should not be run as far as possible through government departments. It has also been suggested by the planning commission that the railways should participate or contribute to the state governments for running all the nationalised road services only when they decide to set up a corporation.^[4]

All the road transport corporations named after a popular or historical figure were changed to the current names after caste violence erupted between the caste groups of Devendrakula Velalars and Maravars in Virudhunagar district (then Kamarajar district), after the formation of Veeran Sundaralingam Transport Corporation (VSTC) by the bifurcation of Pandiyan Roadways Corporation (PRC). The Maravars opposed the naming of the new corporation on Veeran Sundaralingam, who is supposedly believed from the Devendrakula Velalar community.^[5]
