(a) An off-road recreational vehicle may be operated upon
any public road rights-of-way, streets, roads or highways within
Wyoming subject to the following conditions:
(i) Off-road recreational vehicles may be operated on
main-traveled roadways only upon that portion of a public road
right-of-way, street, road or highway designated open by the
state, local or federal agency with jurisdiction over the
roadway and designated a Wyoming off-road recreational vehicle
trail pursuant to W.S. 31-2-701 through 31-2-707 by the
department of state parks and cultural resources. No portion of
a public road right-of-way, street, road or highway shall be
designated as a Wyoming off-road recreational vehicle trail by

shall not be deemed a motorcycle as defined in W.S. 31-1-
101(a)(xv)(E)(I) and 31-5-102(a)(xxii). Nothing in this
paragraph shall be deemed to authorize the department to acquire
or expand any public road right-of-way in order to accommodate
the operation of off-road recreational vehicles;
(ii) Crossings of main-traveled roadways shall be
made at right angles to the roadway or as nearly so as
practicable, but in any case yielding the right-of-way to all
traffic in the main-traveled roadway;
(iii) When operating at any time from one-half (½)
hour after sunset to one-half (½) hour before sunrise, the off-
road recreational vehicle shall be equipped with lighted lamps
and illuminating devices in accordance with W.S. 31-5-910
through 31-5-940;

road recreational vehicle shall be equipped with:
(A) An approved spark arrester;
(B) A noise muffler which produces a propulsion
noise level of not more than one hundred two (102) decibels at
twenty (20) inches in a stationary test.

recreational vehicles operated on public road rights-of-way,
streets or highways for agricultural operations pursuant to W.S.
31-5-124(a)(i).
(b) Nothing in this section authorizes the operation of an
off-road recreational vehicle upon a public road right-of-way,
street, road or highway within Wyoming by a person who has not
been issued a valid driver’s license or permit.
(c) As used in this section, "public road right-of-way"
means the entire right-of-way of a street, road or highway
within Wyoming, including the traveled portions, banks, ditches,
shoulders and medians of a street, road or highway except as
provided in subsection (e) of this section.
(d) Off-road recreational vehicles as defined by W.S. 31-
1-101(a)(xv)(K)(II) that are registered pursuant to W.S. 31-2-

streets, roads or highways within Wyoming, notwithstanding the
designation of the public road right-of-way, street, road or
highway as a Wyoming off-road recreational vehicle trail
pursuant to W.S. 31-2-701 through 31-2-707.
(e) Off-road recreational vehicles as defined in W.S. 31-
1-101(a)(xv)(K) shall not be operated on the roadway or right-
of-way of an interstate highway except as authorized by
department rules and except that an off-road recreational
vehicle under this subsection:

the interstate roadway on a trail where there is a physical
barrier between the trail and the interstate highway and the
