Massachusetts is a “title” state. This means that the person or dealer you purchase your car from must sign over the title to you before you attach your plates and take the car home … even though the dealer may be going to the Registry of Motor Vehicles for you. An insurance stamp is also required before going to the RMV.
Once your vehicle is registered, you have seven days to complete the annual, MA inspection sticker ($29).
