But back to the topic, it's not that she was in a cage with her dog in the back of a truck that would concern me, but that she was in the cage in the back of a truck traveling on a turnpike.
Traveling down a two lane or dirt road at 35 MPH or less...no real big issue. Not wise, but not necessarily inherently dangerous or against the law.
I'm not sure what the vehicle safety laws are in PA regarding passengers riding in open pickup truck beds, but here in Florida, it is very much “against the law”, not to mention insane, to transport live humans, unsecured, in the back of a truck while traveling at legal speeds of 70 MPHs on our turnpikes and highways.
Just saying....
Considering how bad Pennsylvania's roads are, one good bump, and that cage would have flown out of the back.
I've seen it happen. Had a large shipping container strapped to a pallet jump out of the back of a pickup and land right in front of me on I-78. The moron who was driving the pickup went another mile before he realized something was missing.
