Petrol pumps across Delhi have implemented a ban on fuel supply to vehicles without a valid Pollution Under Control (PUC) certificate, following a directive aimed at enhancing air quality. This rule, which was initially announced in October 2025, is now being enforced more rigorously and is set to be a permanent measure. Delhi Chief Minister Rekha Gupta stated that the government is dedicated to improving the environment and tackling air pollution through effective interventions. Under Rule 115 (sub-rule 7) of the Central Motor Vehicles Rules, 1989, all vehicles must possess a valid PUC certificate one year after registration. Despite this requirement, many vehicles continue to operate without certification, contributing to pollution. The enforcement of this directive aligns with the revised Graded Response Action Plan (GRAP) from the Commission for Air Quality Management (CAQM), which calls for strict actions against polluting vehicles, including penalties and potential seizures. Various departments, including the Transport Department and Delhi Traffic Police, are responsible for ensuring compliance.
