All of these statutes apply to the State Trail System on which OHRVs are ridden.
RSA 508:14, I - An owner, occupant, or lessee of land, including the state or any political subdivision, who without charge permits any person to use land for recreational purposes or as a spectator of recreational activity, shall not be liable for personal injury or property damage in the absence of intentionally caused injury or damage.
RSA 215-A:34, II - It is recognized that OHRV operation may be hazardous. Therefore, each person who drives or rides an OHRV accepts, as a matter of law, the dangers inherent in the sport, and shall not maintain an action against an owner, occupant, or lessee of land for any injuries, which result from such inherent risks, dangers, or hazards. The categories of such risks, hazards, or dangers which the OHRV user assumes as a matter of law include, but are not limited to, the following: variations in terrain, trails, paths or roads, surface or subsurface snow or ice conditions, bare spots, rocks, trees, stumps, and other forms of forest growth or debris, structures on the land, equipment not in use, pole lines, fences, and collisions with other operators or persons.
RSA 216-F:3 - No person who has granted a right of way for a trail across his land, or his successor in title, shall be liable to any user of the trail for injuries, suffered on said portion of the trail unless the same are caused by the willful or wanton misconduct of the grantor or such successor in title, as the case may be.

II. An owner, lessee or occupant of premises who gives permission to another to hunt, fish, trap, camp, hike, use OHRVs as defined in RSA 215-A, sightsee upon, or remove fuelwood from, such premises or use said premises for water sports, or winter sports does not thereby:
(a) Extend any assurance that the premises are safe for such purpose, or
(b) Constitute the person to whom permission has been granted the legal status of an invitee to whom a duty of care is owed, or
(c) Assume responsibility for or incur liability for an injury to person or property caused by any act of such person to whom permission has been granted except as provided in paragraph III hereof.
III. This section does not limit the liability which otherwise exists:

(c) The injury caused by acts of persons to whom permission to hunt, fish, trap, camp hike, use for water sports, winter sports or use of OHRVs as defined in RSA 215-A, sightsee, or remove fuelwood was granted, to third person as to whom the person granting permission, or the owner, lessee or occupant of the premises, owed a duty to keep the premises safe or to warn of danger.
