answer:You are suppose to notify the Department of Motor Vehicles and your insurance vehicle whenever you move. Even if it is across the street. Your address is then updated and the taxing authorities are kept abreast of your address in case you live in an area that imposes a personal property tax on your vehicle. It varies by state, but you legally become a resident of another state, in most instances 30 days, you are suppose to have insurance on your vehicle with the new address, your driver’s license and your vehicle tagged, titled and registered with your new address. There are exceptions for active duty military, students and employed outside your home state but maintaining residency at your old address. Residency for college and divorce is different than a resident registering a vehicle.
