Acting tough on those violating emission norms, Irdai has said vehicles without a valid Pollution Under Control (PUC) certificate will not be insured. Irdai in a notification has directed all general insurance companies not to insure a vehicle unless it has a valid PUC certificate. Vehicle insurance is renewed every year. The insurance regulator’s move follows an order of the Supreme Court in this regard. In August last, the apex court in M C Mehta Vs Union of India and Others case had directed insurers not to insure a vehicle unless it has a valid PUC certificate on the date of renewal of the insurance policy.
