Car Smog Test Pakistan 2026 — Requirements, Fees & What Happens If You Fail
What Is the Car Smog Test in Pakistan?
The car smog test — officially called the Vehicle Emission Test — is a mandatory inspection that measures how much air pollution your vehicle produces through its exhaust. In Pakistan, the test is carried out by the Punjab Environmental Protection Agency (EPA) and checks your engine’s exhaust for carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and visible exhaust opacity (smoke density).
Pakistan’s smog crisis, particularly in Punjab, has become one of the worst in the world. Lahore’s Air Quality Index (AQI) regularly crosses 165 — “Unhealthy” levels — with PM2.5 concentrations running around 76 µg/m³, which is roughly 15 times higher than the World Health Organization’s safe guideline. Road transport is one of the biggest contributors to Punjab’s total anthropogenic emissions of 7,017 kilotons per year. The emission test programme is the government’s primary weapon against vehicle-sourced pollution.
Which Cities Enforce the Smog Test?
As of 2026, vehicle emission testing is mandatory throughout Punjab province. The programme was first rolled out in Lahore before expanding province-wide. All vehicles without a valid green emission sticker now face fines and legal action from traffic police and Safe City cameras.
The key cities with active enforcement are:
- Lahore — strictest enforcement, Safe City e-challan cameras in operation
- Faisalabad — active testing stations and police checkpoints
- Rawalpindi / Islamabad — emission testing extended to the federal capital area
- Multan — seasonal crackdowns especially during winter smog months
- Gujranwala — regular testing as part of Punjab-wide programme
- Sargodha, Sahiwal, Gujrat, Bahawalpur — included in the 62-location province-wide rollout
Islamabad (ICT): The Federal Capital is implementing a parallel carbon emission testing requirement. Registration offices have been instructed to verify emission certificates before processing annual licence renewals, with full enforcement expected through 2026.
Who Must Get the Emission Test?
The Punjab EPA has made emission testing mandatory for:
- All private cars and SUVs registered from year 2000 onwards
- All motorcycles and three-wheelers (rickshaws)
- Commercial vehicles including trucks, buses, and vans
- Vehicles older than three years are the primary enforcement target
Even brand-new vehicles are encouraged to test annually to maintain their green sticker and avoid any future compliance issues.
Emission Test Fee Structure 2025–2026
The Punjab government officially ended the free emission testing period and introduced mandatory fees from November 10, 2025. All payments are made digitally via e-Pay — no cash accepted. Fees are deposited directly into the EPA account at time of testing.
| Vehicle Type | Engine Size | Fee (PKR) |
|---|---|---|
| Motorcycle | Any | Rs. 100 |
| Rickshaw / Three-Wheeler | Any | Rs. 300 |
| Car / SUV | Up to 1,000cc | Rs. 500 |
| Car / SUV | 1,001cc – 1,500cc | Rs. 800 |
| Car / SUV | 1,501cc – 2,500cc | Rs. 1,000 |
| Car / SUV | 2,501cc – 4,500cc | Rs. 1,500 |
| Large SUV / Luxury | Above 4,500cc | Rs. 2,000 |
Common cars like the Suzuki Alto (660cc), Suzuki Mehran (800cc), and Toyota Corolla 1.3L (1,300cc) all fall in the Rs. 500–800 fee bracket. Larger vehicles like the Toyota Prado 4,000cc pay Rs. 1,500.
Where to Get the Smog Test Done
Punjab EPA has established 62 emission testing stations across the province. In Lahore alone, testing booths operate at:

What the Test Measures — Pass/Fail Criteria
Your vehicle is tested against Pakistan’s National Environmental Quality Standards (NEQS). The test instruments measure:
| Pollutant | What It Measures | Why It Matters |
|---|---|---|
| Carbon Monoxide (CO) | % volume in exhaust at idle | Toxic gas, causes suffocation |
| Hydrocarbons (HC) | Parts per million (ppm) | Contributes to smog formation |
| Nitrogen Oxides (NOx) | Parts per million (ppm) | Acid rain, respiratory illness |
| Exhaust Opacity | % light blocked by smoke | Visible black/white smoke |
The good news: according to EPA data, approximately 90% of tested vehicles already pass the emission test — especially cars manufactured after 2010. Only about 10% of vehicles fail, and these are mostly older models (15–20 years old) with worn engines or missing catalytic converters.
What Is the Green Sticker and How Long Is It Valid?
Vehicles that pass the emission test receive a green EPA sticker with a unique QR code, which must be displayed on the front windshield. The sticker:
- Is valid for 12 months from the date of issue
- Proves compliance with Punjab Environmental Quality Standards
- Can be verified by traffic police and Safe City cameras via the QR code
- Must be renewed annually (or earlier if the sticker is damaged or removed)
Note: Punjab EPA has extended the validity of stickers issued during the 2025 campaign through June 2026 to give vehicle owners additional time to comply.
What Happens If Your Car Fails the Emission Test?
Failing the emission test does not result in an immediate fine or impoundment — but you do need to act quickly:
- You receive a diagnostic report showing exactly which emissions exceeded limits
- You have 7 days to get your vehicle repaired and return for a free re-test
- Common repairs needed: engine tune-up, air filter replacement, catalytic converter servicing or replacement, oxygen sensor cleaning, or exhaust system repair
- If you still cannot pass after repeated attempts, the vehicle may need major mechanical work
Most vehicles that fail need only a basic tune-up costing Rs. 2,000–5,000. Catalytic converter replacement (for severely polluting vehicles) can run Rs. 15,000–40,000 depending on the model.
Penalties for Driving Without a Green Sticker
If you drive in Punjab without a valid green emission sticker, you face:
| Offence | Penalty |
|---|---|
| First offence (no green sticker) | Rs. 2,000 fine (e-challan) |
| Second offence | Rs. 5,000 fine |
| Repeated non-compliance | Rs. 2,000 – Rs. 10,000 + vehicle impoundment |
| Commercial vehicles (no sticker) | Stricter enforcement, possible route ban |
Fines are issued as e-challans via Safe City cameras — you do not need to be physically stopped by police. The system automatically flags your number plate if your registration record shows no valid emission certificate.
Vehicles may also be temporarily impounded until a valid emission certificate is presented. During the Punjab government’s smog crackdown (October–January each year), enforcement is significantly stricter.
How to Prepare Your Car for the Emission Test
To maximise your chances of passing on the first attempt, carry out these basic maintenance checks beforehand:
- Engine air filter: Replace if not changed in the past 12,000–15,000 km. A dirty filter causes rich fuel mixtures and high HC emissions.
- Spark plugs: Worn plugs cause incomplete combustion and high CO/HC. Replace every 30,000–40,000 km.
- Oxygen (O2) sensor: A faulty O2 sensor leads to incorrect fuel-air mixture and elevated emissions. Clean or replace if the engine warning light is on.
- Catalytic converter: The most important component for passing. Do not remove or bypass your cat converter. If it is damaged, have it serviced before the test.
- Engine oil: Old, dirty oil increases blow-by gases. Change oil before the test if overdue.
- Warm up the engine: Drive for at least 10–15 minutes before the test so the catalytic converter reaches operating temperature (800°C+). Cold catalytic converters do not function efficiently.
- Fix visible smoke: Blue smoke means burning oil; black smoke means rich mixture; white smoke may indicate coolant leak. All will cause an automatic fail.
Tips to Reduce Your Car’s Emissions Long-Term
Beyond passing the annual test, here are habits that keep your car’s emissions in check year-round:
- Switch to Euro-5 or better fuel where available (reducing sulphur content)
- Avoid prolonged engine idling — switch off at railway crossings and long signals
- Use quality engine oils and stick to the manufacturer’s service schedule
- Keep tyres properly inflated — under-inflated tyres increase fuel consumption and emissions by up to 3%
- Consider a CNG or LPG conversion from an OGRA-approved workshop if you drive long distances — CNG produces significantly lower CO than petrol

Frequently Asked Questions — Car Smog Test Pakistan
Is the emission test compulsory for cars in all provinces or only Punjab?
Currently, mandatory emission testing with green sticker enforcement is active across Punjab province. Islamabad (ICT) is implementing a parallel requirement. Sindh and KPK have their own environmental regulations but do not yet have a province-wide green sticker scheme equivalent to Punjab’s.
How often do I need to get the emission test done?
The green sticker is valid for 12 months. You must renew it annually. Punjab EPA has periodically extended deadlines during the rollout phase, but going forward, annual renewal before expiry is mandatory.
Can I drive to another city if my car does not have a green sticker?
No. Punjab has banned vehicles without green stickers from motorways and major roads. If you are caught at a checkpoint or flagged by a Safe City camera, you will receive an e-challan regardless of which city you are in within Punjab.
What if my car is new (less than 3 years old)?
New vehicles under 3 years old are generally assumed to be emissions-compliant and may be exempt from mandatory testing in the initial enforcement phase. However, the EPA recommends all vehicle owners test annually. Check with your local EPA office for the current exemption criteria.
How long does the emission test take?
The actual test takes approximately 5–10 minutes. However, waiting time at busy testing centres can be 30–60 minutes. Going during off-peak hours (early morning on weekdays) reduces waiting time significantly.
Can I get fined via the camera without being stopped by police?
Yes. Punjab’s Safe City cameras are integrated with the vehicle registration database. If your registration record does not show a valid emission certificate, you can receive an e-challan automatically when your number plate is scanned on the road — no police interaction required.
What happens if I remove the green sticker from my windshield?
The green sticker is designed to be tamper-evident. Removing it voids the sticker. You would need to re-test and obtain a new sticker. Do not remove it unless replacing it upon expiry.
Does the emission test check anything other than exhaust gases?
The primary test is exhaust emission measurement. However, EPA inspectors may also conduct a visual inspection for obvious defects such as broken exhaust pipes, excessive visible smoke, or missing catalytic converters.
