Step 1: Visit the PUC Center:

Drive your vehicle (two-wheeler, car, or any other vehicle) to the chosen authorized PUC testing center. Ensure you carry your vehicle's Registration Certificate (RC) for verification. While not always mandatory to present, it's good practice to have it. Step 2: Undergo the Emission Test:

The operator at the PUC center will conduct an emission test using a specialized gas analyzer connected to your vehicle's exhaust pipe. For petrol/CNG/LPG vehicles, the levels of Carbon Monoxide (CO) and Hydrocarbons (HC) are checked. For diesel vehicles, the smoke density is measured. You might be asked to start your vehicle and rev the engine as instructed by the operator during the test. Ensure your vehicle's AC is turned off during the test. Step 3: Receive the PUC Certificate:

If your vehicle's emission levels are within the permissible limits set by the government, the operator will generate the PUC certificate. The certificate will contain details such as your vehicle's registration number, the PUC certificate serial number, the date of the test, the validity date, and the emission readings. Verify all the details on the certificate are correct before leaving the center.
