Logan • A far northern Utah county says it’s ditching a system that determines whether vehicles are working properly based on tailpipe testing.

The Cache County Council voted last week to rely on vehicles' own diagnostic testing. A scanner can reveal whether vehicles are in good working order.

The Herald-Journal in Logan reports that the change is expected in 2021.

County attorney James Swink says tailpipe testing is expensive. And, he says, it doesn’t makes economic sense as older vehicles get replaced by newer ones that have the technology to monitor emissions.

The council implemented an emissions and maintenance program in 2014 to improve air quality.
