When do I need an inspection sticker and registration for my new car in Massachusetts by?

I just bought a 2014 Honda Civic Ex in Massachusetts today, and there's no inspection sticker or registration. There's an oil change sticker on it. I tried calling the car dealer but he didn't return my call yet. Will I get in trouble if I drive it to work tomorrow? I work in New Hampshire, by the way.

You have no inspection or plates? Yeah, you will have trouble. Are you a Mass resident? Did you buy the car in MA? If so, why didn't you have the dealer register and inspect it for you. Most of them will do it and only charge the actual costs of registration. Beats standing in line at the RMV.

However, since MA does not do temporary plates, you CAN use your old ones on your new car for up to 7 days before you get a chance to transfer them to the new car. Keep your bill of sale in your car for proof.
