emissions test
Tailpipe pollution screening
An emissions test is an inspection of a vehicle's exhaust to measure pollutants released into the air.
Many jurisdictions require periodic emissions testing for vehicle registration, ensuring cars meet environmental standards: My car failed its emissions test, so I had to get the catalytic converter replaced.
