1. Need For PUC

Pollution caused due to vehicles can have adverse effects on people’s health as well as the environment. At a time when city’s pollution levels are on the rise, every citizen must play their part to curb pollution.

Carpooling, choosing public transport, cycling, maintaining your vehicle, and keeping your vehicle’s pollution level in check are small steps one can take for the betterment of the environment. The need for a PUC certificate is felt to ensure that vehicles do not cross the pollution limits and if they do so, then the respective vehicle owners are penalized with RTO traffic fines.

2. What does the law say?

It is mandatory to get a PUC certificate as per Central Motor Vehicles Rules, 1989. It is compulsory to keep renewing the PUC certificate from time to time else one needs to pay RTO fines. A PUC certificate is generally valid for a year in case of four-wheelers and for six months in case of two-wheelers. The PUC certificate is a compact receipt that is given to the vehicle owner after the vehicle meets the following criteria:

Type of VehicleCarbon Monoxide (%)Hydrocarbon (PPM)
2 and 3 wheelers (2/4-stroke) manufactured on or before 31st March 2000



2 and 3 wheelers (2-stroke) manufactured after 31st March 2000



2 and 3 wheelers (4-stroke) manufactured after 31st March 2000



4 wheelers manufactured according to Pre Bharat Stage II Norms



4 wheelers manufactured according to Pre Bharat Stage II, Stage III or subsequent norms



The charges to get a PUC certificate are around Rs. 100. Precise cost depends upon your vehicle. Driving a vehicle without getting a PUC certificate or not renewing an expired PUC certificate is an RTO traffic violation. The RTO traffic fine for driving without a valid PUC certificate is Rs. 1000. For repeated offense, it is Rs. 2000. Thus, it is suggested to renew your PUC certificate before its expiry date to avoid RTO fines.

3. From where to get a PUC certificate?

It is extremely easy to get a PUC certificate. You might have seen vans near highways with PUC written on them. You can get your PUC certificate from there. Several petrol pump outlets also have a stall from where you can get your PUC certificate.

The process takes around five minutes and requires the owner to just switch on the engine for a few seconds. The executive checks the necessary figures as mentioned in the table with the help of a hand-held machine and notes down the numbers. If they are in accordance with the numbers stated by law, you will receive your PUC certificate. The expiry date is mentioned on the certificate, that is when you have to get your PUC certificate renewed.

Driving without a valid PUC certificate is illegal and will result in RTO fines. Keep a track of your PUC certificate’s expiry date by setting a reminder on your mobile phone.
