Can an out-of-state vehicle with a cardboard tag be tested in Pennsylvania?

A vehicle with a cardboard tag can indeed be tested in Pennsylvania if it is capable of being driven on the highway. This is primarily because the cardboard tag signifies that the vehicle is currently registered, albeit temporarily, which allows for it to be legally operated on public roads. As long as the vehicle meets the necessary condition of being roadworthy, it can undergo the emissions testing required in Pennsylvania.

The other options may erroneously imply restrictions or preconditions that do not align with the regulations regarding emissions testing for temporary registration situations. Recognizing that the ability to drive the vehicle legally is a crucial factor is essential in understanding this aspect of emissions testing procedures in Pennsylvania.
