Currently, vehicles registered in the Philadelphia region (Bucks, Chester, Delaware, Montgomery and Philadelphia counties) and the Pittsburgh region (Allegheny, Beaver, Washington and Westmoreland counties) are required to undergo an annual emissions inspection prior to receiving a new safety inspection sticker.
Diesel-fueled vehicles are not required to participate in Pennsylvaniaâs emissions inspection program because the federal Environmental Protection Agency (EPA) has not yet approved, and required, an emissions inspection for diesel-fueled vehicles.
