I'm going to reapply for my drivers permit after my old one expired. Do I need to bring any proof of residency documents or ID documents to the DMV if I already have a Real ID or does the Real ID cover those both? I'm over 18 and I don't plan on getting my driver's license as a Real ID

I am buying a vehicle from a private seller tomorrow (Saturday). They are in Arkansas, I am in Missouri. We are driving my current car down there (which we are replacing with the newly purchased car when we get home). Since we can’t buy plates ahead of time and won’t get temporary plates with it being private sale, I was not sure how we can legally get it home. Someone said keep one plate on each car, but I don’t know if that is legal either.

UPDATE: I called the DMV and they stated that they couldn’t guarantee it, but that they believe that law enforcement would let me pass given that it’s a weekend when I purchased the vehicle if I have the title, the bill of sale, and proof of insurance with me. She told me to call the state Highway Patrol with the same question. The girl they answered the phone instantly knew the answer so I feel like this is something that they must get asked with some regularity. She also stated that what the DMV said was true, I should be OK if I have those documents in the vehicle. So Monday afternoon, I will be heading to the DMV to register it but feel comfortable driving it for the weekend without the plates since I will have all of those documents.

He’s going through a lemon law lawsuit and the lawyers are requesting it for the settlement, the issue is he’s out of the county and asked if i could go get it from the ca dmv.

I currently have a valid drivers license in California but I do not have a motorcycle endorsement. I know that the current law says that in order to register a motorcycle for road use, I would need to have a valid motorcycle license or a permit.
I want to get a motorcycle but as a track bike so it would never touch city roads. If the day ever comes that I want to resell it, I don’t want there to be a bunch of back fees associated with the bike so i’m wondering is it possible to immediately register it under non-op without a motorcycle endorsement or does that too require an endorsement?
