From the Myrtle Beach Online:
Emissions tests of 1995-model and older vehicles ended Saturday, exempting some of Charlotte's likeliest polluters from the dragnet intended to catch them.
Annual emissions tests for those vehicles no longer will be required in Mecklenburg, Gaston, Cabarrus, Union and the five other N.C. counties where they've been the law since the early 1990s. More than 600,000 cars and trucks - one vehicle in four in those counties - will get a pollution pass.
Older vehicles are those most likely to flunk the tests, state records show.
So the genius of this state stops testing the cars most likely to emit pollution.
