Not sure about the other states, but Ca. would require you to get a temporary moving pass to drive on the roads, even if you were from out of state and picking it up and driving it back home to another state. The CHP would tell you, if you got pulled over that you should have checked with the local DMV before driving the vehicle. (personal experience)
They are free I believe in CA. I would check with each state through their web site and make sure.
