The largest source of ozone pollution in the Austin metropolitian area is motor vehicles. This isn't suprising when we consider that over half a million motor vehicles are registered in this area. Each one of them has the potential to be a source of ozone pollution. The emissions from one poorly maintained automobile equal that from 25 properly-funcitoning cars.
