Driving recently purchased truck what's needed to drive it home?

I won a bid in Richie Bros "Truck planet", the truck is in Michigan and I have to bring it to Southern California, I have the insurance already, my question is, did you even went inside the scales? I don't know if Richie bros going to issue the temp plates, but since I'll be out of commerce, do I have to abide by the HOS rules with a 18k bobtail? When you went to the DMV did they charge you per every state or just a one time fee for the permit?

 

Non trucking liability insurance, bobtail coverage, maybe a temp tag if your buying from a dealer, be sure you have a bill of sale and or title, current inspection.. Or contact company you're leasing to and ask for documentation to get truck home. OR Use Personal Conveyance. Scales I never stop when under P.C. Yes I am an O/O. I'm sure there are some that will say that's not legal but 43 years can't be too wrong. No tickets.
