Tracked OHRV Registration Requirements
As of July 1, 2012, in order to operate on state-approved snowmobile trails, an OHRV (wheeled vehicle) that has had the wheels or tires removed and replaced with tracks, cleats or skis, MUST be properly registered in New Hampshire as a snowmobile.
The tracked OHRV must meet the definition of a snowmobile as defined by law.
The OHRV, with the tracks on, cannot exceed 54 inches in width and 2000 pounds.
If operating as a wheeled vehicle, a New Hampshire OHRV registration is required.
Machines operated as a tracked OHRV on snowmobile trails in the winter, and as a wheeled OHRV, must be dually registered in New Hampshire; both an OHRV and snowmobile registration are required. Both sets of decal stickers must be displayed on the machine
