TAC APPROVAL FOR AUTOMOBILE: The Certification that production samples of a design will get after achieving specified performance standards is known as vehicle type approval. With the implementation of the India Central Motor Vehicles Rules in 1989, AIS certification became available (CMVR). The CMVR publishes rules and regulations relating to vehicle approval, traffic restrictions, and the production and maintenance of motor vehicles, among other things. The Ministry of Road Transport and Highways is the responsible body for enforcing emission legislation, including Type Approval and production Conformity. The MORTH has established a standing Committee on Emission Legislation implementation, chaired by joint Secretary of MORTH, to advise the nodal agency on such implementation. TACs are awarded for products that must meet stringent technical and safety standards.
If the number of base models and variants manufactured/imported is more than one, and the individual base model and variants are less than 250 in any six-month period in a year, the testing agencies may select one vehicle from among such models and variants once a year to conduct such tests.
