The state government of Bihar has given high emphasis to developing a first-rate infrastructure for the swift movement of people and goods. The State of Bihar will have 4,006 km of state highways and 5,358 km of national highways as of 2022. Now, why is road tax in Bihar levied at State level? Since every state is responsible for paying for its own portion of the expense of the construction of these highways, every state imposes its own road tax.

Why is Road Tax Levied at State Level

For safety and maintenance of the roads and traffic plying on them, the state government has set up a separate department for regulation and compliance of the provisions of Motor Vehicles Act, 1988. This Department of Transport (DoT) ensures that there is smooth implementation of the central law, MV Act and the rules laid thereunder. The state has been conferred the power by the Constitution to collect road tax and DoT helps in maintaining its well ordered functionality.
