Rev. Stat. § 215-C:9, VI; provided, however, a snowmobile may be driven upon the right of way of any railroad for a crossing of the tracks at their intersection with an authorized trail, road, or highway where a snowmobile is not otherwise prohibited. Any person violating the provisions of this paragraph shall be guilty of a violation for the first offense and shall be guilty of a misdemeanor for any subsequent offense.
VII. No person shall operate a snowmobile upon any airport runway or landing field, or within cemeteries, except in an emergency pursuant to the provisions of N.H. Rev. Stat. § 215-C:9, VI.

IX. Pursuant to N.H. Rev. Stat. § 215-C:31, city or town councils and boards of selectmen may authorize the use of sidewalks and class IV, class V, or class VI highways and bridges, or portions thereof, for use by snowmobiles. The operation of snowmobiles may also be allowed on sidewalks adjacent to class I, II, III, or III-a highways pursuant to N.H. Rev. Stat. § 236:56, II(e). Operators of snowmobiles using said roads, or portions thereof, shall keep to the extreme right and shall yield to all conventional motor vehicle traffic. The bureau, or its designee, shall so post such highways where authorized. Following a duly noticed public hearing, except in the case of an emergency closure, such city or town authorities may change the allowable usage of a class IV, class V, or class VI highway by snowmobiles by giving notification to the supervisor of the bureau and removing any signs that no longer apply.
X. A person may operate a snowmobile across any public way where the operation of said snowmobile is not otherwise prohibited by law, but said person shall comply with the following provisions:
(a) The crossing shall be made at an angle of approximately 90 degrees to the direction of the public way and at a place where no obstruction prevents a quick and safe crossing;
(b) The operator shall bring the snowmobile to a complete stop before crossing the shoulder or, if none, the public way, before proceeding;
(c) The operator shall yield the right of way to all motor vehicle traffic on such public way which constitutes an immediate hazard to such crossing; and

No person shall operate a snowmobile on the traveled portion of any public way classified as a class I, class II, class III, class III-a, class IV, class V, or class VI highway, where said highway is maintained for winter use by conventional motor vehicles, except as specifically provided in paragraphs IX and X, and in accordance with paragraph XII.
XII. In those instances where a municipality does not maintain a class IV, class V, or class VI highway for winter use by conventional motor vehicles, the city or town council or board of selectmen may authorize the use of such a highway by snowmobiles; or, alternatively, it may authorize dual use of such highway by snowmobiles and by those conventional highway vehicles that are being used solely for access to property abutting such highway. Vehicles of any type being used for law enforcement, firefighting, rescue, and road maintenance shall have unrestricted access to such highways in either case. The bureau or its designee shall post said highways in accordance with the status established by municipal authorities as provided in this paragraph. Following a duly noticed public hearing, except in the case of an emergency closure, such authorities may change the status of a highway by giving notification to the supervisor of the bureau and removing any signs that no longer apply.
XIII. Notwithstanding any other provision of law, a snowmobile may be operated within the right-of-way of a public way across a bridge when operated in accordance with a permit issued by the commissioner of public works and highways pursuant to N.H. Rev. Stat. § 215-C:2, IX.
