You may not even realize you're doing it, but if your car engine is idling while waiting in a drive-through line, especially on days that already have bad air quality, you may be contributing to a hyper-local hotspot of air pollution. A new study by University of Utah researchers monitored the air quality at drive-through COVID-19 testing sites to assess the impact of idling on air quality and found that during temperature inversions, emissions from idling vehicles caused a local pollution hotspot in the testing area, potentially exposing workers providing COVID tests to elevated levels of air pollution.
