A Pollution Under Control Certificate is easy to postpone because the test is usually quick. The useful habit is not simply renewing it: check that the slip belongs to your vehicle and that the validity date is visible before you leave the testing centre.
What the certificate should show
The prescribed Form 59 format includes the registration number, manufacturing details, fuel, PUC code, fees, test fields and a validity date. It may also carry a QR code and the vehicle image. Before you drive away, match the registration number and fuel type to your RC, and make sure the expiry date is legible in the photo or PDF you keep.
Build a simple renewal routine
Set two reminders: one a month before expiry and one a week before. Carry or retain a digital copy with your other vehicle papers. Delhi Traffic Police notes that RC, insurance and PUC can be shown from DigiLocker or mParivahan where accepted, but a digital copy is not a substitute for ensuring the certificate itself is current and correctly issued.
When the reading needs attention
A PUC test is not a full diagnosis. If a centre flags an abnormal reading, do not assume a tune-up is the only answer. Ask for the measured value, retain the slip, and have an authorised workshop investigate the likely cause. An illuminated malfunction indicator or a noticeable change in fuel economy also deserves attention before a re-test.
Keep the documents together
- RC or its valid digital record
- Active insurance record
- Current PUC certificate
- Service invoices relevant to an emissions complaint
The official Form 59 PUCC format is a useful reference for the fields you should see. Requirements and enforcement can vary by State, so use the relevant transport department for local rules.
