Bryan,
What Matt didn't tell you is that if a PA car has a current inspection sticker on the windshield, for the most part, you can assume that the car is in good mechanical condition adn probably physical condition. (???)
When a mechanical inspection is performed, the inspector (mechanic) will use a variey of instruments and gauges to determine if the parts being inspected are within the minimum operating tolerances. For example: The thickness of the brake lining, the rotors, the drum diameter and the rotor runout will all be measured to within thousandths of an inch and then recorded on the inspection form. The wheel cylinders and calipers will be checked for leaking fluid or cracked/split rubber boots. The ball joints are measured for play. Tie rod ends, idler arm, pitman arm, etc. are all checked for play. The exhaust cannot leak and there are to be no holes in the body where exhaust fumes can enter the cabin or rough sheet metal that can injure a pedestrian. Any part or part of the car that does not meet the specifications and tolerances the car fails the inspection and cannot be driven on the road until the repairs are made and the car is re-inspected. Every inch, system and part of the car is to be inspected. I think you get the idea.
PA has one of the toughest auto inspections in the country. It has been that way for many a decade. The State police come around periodically and inspect the inspection stations and the inspectors (mechanics). If the records are not correct and the mechanics are not doing the inspection properly, fines can be levied and inspection licenses revoked.
Of course, sometimes things are allowed to pass and there is always going to be a black market for illegal inspections stickers. But, for the most part, the vast majority get their cars inspected.
