For a non-transport vehicle in Assam, what is the validity period for the registration certificate after it has been renewed?

The correct answer is 5 year . Key Points Initially, the registration certificate for a non-transport (private) vehicle in Assam, like elsewhere in India, is valid for a period of fifteen years from the date of its first registration. After the completion of this initial fifteen-year period, the vehicle's registration certificate must be renewed to remain legally valid for use on public roads. Upon renewal, the registration certificate for a non-transport vehicle is then valid for a subsequent period of five years. This five-year renewal cycle continues as long as the vehicle is deemed roadworthy after inspection by the registering authority. This periodic renewal and inspection process ensures that older vehicles continue to meet safety and emission standards, contributing to road safety and environmental protection.
