(Harrisburg) -- A state senator says federal vehicle emissions testing required in a number of midstate counties should be rolled back. Democrat John Wozniak is the minority chairman of the Senate Transportation Committee. He says technological improvements have made the inspections obsolete. "There's an entire new fleet of cars. It's been a generation since this was put in. The cars are much more technologically advanced than they were 10 years or 20 years ago. The garages might moan, but the fact is these (emissions testing) machines have been paid for many times over now," Wozniak says. He has introduced a bill that would ask Congress to re-evaluate the testing. The Johnstown-area lawmaker says repealing the law would put money back in the pockets of drivers who have to pay for emissions testing. Berks, Cumberland, Dauphin, Lancaster, Lebanon and York counties are among the 25 that require emissions evaluations statewide. Pennsylvania first required vehicle emissions testing a handful of counties in 1997.
