If you purchase your snowmobile from a dealership, they will process the title transaction for you and issue your sticker. If you buy your snowmobile via a private sale, you must go to a licensed Maryland title service, where they will electronically process the registration for you. You must present a completed Application for Certificate of Title and a completed Application for Title Decal for Mopeds, Motor Scooters, ATVs, UTVs, Off-Road Motorcycles and Snowmobiles.
