What does it mean when exhaust emissions are detected as exceeding the standard on the road?

[Paisley]

Detecting excessive exhaust emissions on the road means that the vehicle's emissions exceed the legal limits. Below is relevant information: 1. Indication of excessive emissions: When driving, the electronic screen may display a warning for excessive emissions. If remote sensing detects non-compliant emissions, the owner may face fines. Traffic police will issue a correction notice with a deadline, requiring the owner to undergo a re-inspection as per regulations. 2. Remote sensing detection: When a vehicle passes by and its emissions exceed the standard, remote sensing technology records the license plate number of the offending vehicle through data analysis. The traffic management department's connected database can then retrieve other detailed information about the vehicle, and the owner will be notified to repair the vehicle before undergoing another inspection. Traditional manual testing of vehicle emissions has many inconveniences, as it takes a long time and involves lengthy procedures.
