Oh no, you put said Printed Temp MD Tag on the stolen car after you have a juvenile steal it for you!
MD doesn't have reciprocity or any number for DC police to pull up, so just drive easy.
Car won't match the plates, because there are no plates, just a beautiful, newly printed paper Maryland Temp Tag!

Place it on the far right side of your vehicle, i.e. Gas Cap, passenger door area, closest to the street for someone to walk by with a phone.
