Can I drive my pick-up truck on a parkway in New York State?
In addition to the New York State Department of Transportation, other agencies (Office of Parks, Recreation and Historic Preservation and the Palisades Interstate Parkway Commission, for example) or entities (such as Westchester County and New York City) have jurisdiction over parkways in New York State.
Different parkways have different vehicle restrictions. New York State law prohibits trucks from those parkways that are under the jurisdiction of NYSDOT; these include the Cross County, Hutchinson River, Saw Mill River, Sprain Brook and Taconic State Parkways.
In New York State, a "truck" is defined as a motor vehicle that is designed, used or maintained primarily to transport property. A truck or a van that is legally registered as a passenger vehicle and that has passenger plates (tags), however, is not considered to be a truck.
Motor vehicle owners in New York State register their vehicles with the Department of Motor Vehicles, not the Department of Transportation.
