Lahore Emission Scanners to Target Polluting Vehicles

Lahore is moving toward a new way of checking smoky vehicles. According to source reports, the Environment Protection and Climate Change Department is preparing a pilot system that will scan vehicles as they drive past, instead of waiting for them to stop at a roadside check point.

The plan is aimed at vehicles that give off too much pollution, and it is meant to work without blocking traffic. For Lahore motorists, that means the city may soon start spotting high-emitting cars, vans, buses and trucks through camera and sensor data rather than only by visible smoke.

Nine points are planned for the pilot

According to sources, the pilot will be set up at nine entry and exit points in Lahore. The report does not name the exact locations or say when the system will go live.

The new setup will use remote sensing devices, or RSDs, placed along selected traffic corridors. These devices can measure emissions from moving vehicles while they stay in motion, so drivers do not need to stop.

The same reports say the system will also record registration numbers and related details. That will let officials match an emissions reading with a specific vehicle.

What happens if a vehicle is flagged?

According to a source report, vehicles that show high emissions may be sent for further inspection or regulatory action. But the available report does not give any fine amount, penalty rule or enforcement date.

This is important for readers because it means the announcement is still a pilot plan, not a citywide punishment drive. Motorists should not assume they have already been officially warned unless a notice comes from the department or Punjab EPA.

Why the city is using scanners instead of smoke checks

The reports say the system is meant to screen a much larger number of vehicles than visual smoke checks or standard roadside testing. That could help officials find vehicles that look fine at idle but still pollute heavily on the road.

Secretary Silwat Saeed said the idea is to allow the department to screen vehicles in real driving conditions. She also said vehicle-specific data can support evidence-based regulation and help officials decide which vehicles need detailed testing.

The project is part of the Lahore Air Improvement Framework. According to sources, a technical committee reviewed the system on August 24 and looked at equipment specs, measurement accuracy, pollutant readings, detection limits, vehicle speeds and camera integration.

PEMS checks will back up the scanner readings

The reports also say portable emission measurement systems, or PEMS, will be used on selected vehicles for deeper testing while driving. These tests will help verify the readings taken by the roadside scanners.

The Punjab Environmental Protection Agency will also set up a Vehicular Emission Testing Unit to handle technical work, quality checks and implementation.

What motorists should do now

For now, the safest step is simple maintenance. Drivers should fix visible smoke, get overdue tuning done, replace weak air filters, and check injectors and sensors if the vehicle feels rough or smells unusual. Keeping registration papers and other documents up to date is also wise.

Older or poorly maintained vehicles may face more risk of being flagged, but no specific model, fuel type or age group has been named in the available reports. How well the system works will depend on calibration, privacy safeguards and a fair appeal process.

Lahore is not getting an instant penalty net. It is getting a technology-led screening pilot, and the final rules will matter as much as the scanners themselves.
