Commercial vehicles such as taxis, trucks, school vans, buses, and construction vehicles operate more frequently and cover longer distances than private vehicles. Because of this higher usage, emission compliance becomes even more important. In India, every commercial vehicle running on public roads must carry a valid Pollution Under Control (PUC) certificate as per guidelines issued by the Ministry of Road Transport and Highways under the provisions of the Motor Vehicles Act.
A PUC certificate confirms that your vehicle’s emission levels are within the permissible limits prescribed by law. It is issued after an emission test conducted at an authorised pollution testing centre. These centres are commonly located at petrol pumps, RTO-authorised kiosks, and designated testing facilities.
For commercial vehicles, compliance checks are stricter compared to private vehicles. Taxis, school vans, and trucks are frequently inspected during traffic drives, highway enforcement checks, and special RTO campaigns. Authorities may check documents such as vehicle registration (RC), permit, fitness certificate, insurance, and PUC during inspections.
PUC Validity for Commercial Vehicles
- New commercial vehicle: PUC is valid for 1 year from the date of registration.
- After the first year: PUC must be renewed every 6 months.
There is no separate nationwide 3-month validity rule for commercial vehicles unless state-specific directives apply. However, due to frequent enforcement drives, operators often feel the scrutiny is higher.
Older diesel trucks and high-usage taxis may face stricter emission readings during tests. Vehicles that fail emission tests must undergo necessary repairs and re-testing before operating legally on public roads.
Why PUC Compliance Is Crucial for Commercial Vehicles?
For commercial operators, an expired PUC is not just a minor violation. It can lead to:
- Monetary fines
- Temporary vehicle detention
- Increased scrutiny during permit renewals
- Operational disruptions
- Possible complications during insurance claims
Since commercial vehicles generate income daily, even a one-day detention can result in financial loss. That is why taxi drivers, fleet owners, and logistics operators should track PUC expiry dates carefully.
Interstate PUC Rules Every Commercial Driver Should Know
Emission standards are centrally regulated. This means a valid PUC issued in one state is generally accepted across India, provided it is recorded in the central database system. Enforcement agencies often verify validity digitally through central transport databases.
Below are some of the most common real-life doubts commercial vehicle operators have about PUC compliance:

No

Question
|
Answer
|
|
1
|
Is PUC validity different for commercial vehicles like taxis and school vans?
|
No, after the first year from registration, both personal and commercial vehicles require PUC renewal every six months. However, commercial vehicles are inspected more frequently, which creates the perception of stricter rules.
|
|
2
|
Do app-based taxis (Ola/Uber) need more frequent PUC checks?
|
There is no separate national rule requiring more frequent PUC checks for app-based taxis. They follow the same six-month renewal cycle. However, aggregator platforms may suspend drivers if documentation is not valid.
|
|
3
|
My truck operates across multiple states. Do I need a separate PUC for each state?
|
No. A valid PUC certificate is accepted across India because emission standards are centrally regulated. You do not need separate PUC certificates for each state.
|
|
4
|
Can my commercial vehicle permit be suspended if PUC is expired?
|
Permit suspension is not automatic. However, repeated violations or operating without valid emission compliance may attract penalties and regulatory scrutiny that could impact permits.
|
|
5
|
What is the fine for expired PUC for commercial vehicles?
|
Under the Motor Vehicles Act:
- Rs. 1,000 for the first offence
- Rs. 2,000 or more for repeat offences
Commercial vehicles may face stricter enforcement during inspections
|
|
6
|
If my truck fails PUC, can I still transport goods until I repair it?
|
If a vehicle fails the emission test, it should be repaired immediately. Driving without a valid PUC may result in fines if caught during enforcement checks.
|
|
7
|
During school vehicle inspection, can authorities detain the vehicle for no PUC?
|
Yes. During school transport safety drives, authorities may detain or penalise vehicles operating without valid PUC.
|
|
8
|
Does vehicle age affect PUC frequency for commercial vehicles?
|
The renewal frequency remains six months after the first year. However, older vehicles, especially diesel trucks, may face stricter emission testing and higher chances of failure.
|
|
9
|
If my taxi’s PUC is expired, can passengers report it through traffic apps?
|
Some states allow traffic violations to be reported through official apps. While it may not lead to instant fines, it can trigger enforcement action.
|
|
10
|
Is PUC mandatory for construction vehicles and heavy equipment?
|
If construction vehicles (such as dumpers or site trucks) operate on public roads, valid PUC is required. Equipment used strictly within private premises may not require PUC.
|
|
11
|
Does a temporary permit vehicle also need a valid PUC?
|
Yes. Permit type does not change emission compliance requirements. Any vehicle operating on public roads must have a valid PUC.
|
To Conclude
While insurance can be purchased even if a PUC certificate has expired, maintaining valid emission compliance is advisable. During claim investigations, authorities and insurers may examine whether the vehicle was legally compliant at the time of the incident. Keeping all documents updated reduces operational and legal risks.
