Putting all uncertainties to rest over the registration of BS-III vehicles after April 1, the road transport ministry has said only manufacturing of such vehicles are not allowed after March end. The inventory of old (manufactured) vehicles, however, "needs to be protected and registered". The ministry has framed its stand on the issues raised by the Supreme Court appointed body, EPCA, which wants to put a stop to registration of vehicles which don't comply with BS-IV emission norms from March 31, linking pollution under control certificates with the annual vehicular insurance to curb air pollution. The road transport ministry has shared its stand with heavy industries ministry and has asked it to submit its stand in the Supreme Court.
