The state classifies trike scooters with an engine displacement of 50cc or more as motorcycles, requiring a motorcycle endorsement on your driver's license. Additionally, you must comply with specific safety and equipment regulations for motorcycles. Always check with the New York Department of Motor Vehicles for the most current requirements.
In most States they require a Motorcycle Operators License in addition to a regular Drivers License. My State requires a drivers license for under 50cc use on roads, while NY requires the scooter or moped to be registered with license plates also. Every State has their MVB rules and regulations available on the internet. If you were able to read my answer then surely you could also find the answer for your specific State.
