What is the PUC Certificate?
A Pollution Under Control (PUC) certificate is a mandatory document that certifies a vehicle's emissions are within the prescribed limits set by law. Under the Central Motor Vehicles Rules, 1989, every vehicle must have a valid PUC certificate after one
year from its initial registration. This applies to all petrol, diesel, CNG, and LPG vehicles. The primary purpose of the PUC check is to identify and curb polluting vehicles, a significant contributor to Delhi's air quality problems. Electric vehicles are exempt from this requirement due to their zero tailpipe emissions.
Why the Strict Enforcement Now?
The enforcement drive, which began on October 1, 2026, is a critical component of the region's Winter Action Plan and the Graded Response Action Plan (GRAP). These plans are designed to preemptively tackle the severe spike in air pollution that Delhi-NCR experiences every winter due to factors like stubble burning, lower temperatures, and reduced wind speed. By making it difficult for non-compliant vehicles to operate, authorities aim to reduce vehicular emissions before the pollution season peaks. The Commission for Air Quality Management (CAQM) has directed states across the NCR, including districts in Uttar Pradesh, Haryana, and Rajasthan, to implement the rule.
The 'No PUC, No Fuel' Mandate
The core of the policy is straightforward: fuel stations across Delhi and the wider NCR are required to deny petrol, diesel, or CNG to any vehicle that does not have a valid PUC certificate. To enforce this, around 500 fuel stations in Delhi, and over 1,000 across the NCR, are being equipped with Automatic Number Plate Recognition (ANPR) cameras. These cameras scan a vehicle's number plate upon entry and check its PUC status against a central database. If the certificate is invalid or has expired, the pump will not dispense fuel. At stations where ANPR systems are not yet active, staff have been instructed to manually verify the certificate.
Penalties for Non-Compliance
Driving without a valid PUC certificate is a punishable offence under the Motor Vehicles Act. Vehicle owners caught without one can face a hefty fine of ₹10,000, imprisonment for up to six months, or both. This is in addition to being denied fuel at the pump. Repeated offences can even lead to a suspension of the driver's licence for up to three months. The enforcement is not just limited to fuel stations; traffic police are also conducting roadside checks and issuing challans to violators.
How to Get and Renew Your PUC
Getting a PUC certificate is a relatively simple offline process. You must take your vehicle to an authorized emission testing centre, which can often be found at petrol pumps or as standalone workshops. A technician will insert a probe into the exhaust pipe to measure emission levels. If the vehicle passes, a certificate is issued. The cost is regulated, typically around ₹60-₹80 for two-wheelers and petrol cars, and ₹100 for diesel vehicles. For new BS-IV and BS-VI compliant vehicles, the certificate is valid for one year, while for older vehicles, it may require more frequent renewal. While the test is offline, you can download a digital copy of your certificate from the official Parivahan portal using your vehicle's registration and chassis number.
