045-23 Wyo. Code R. § 23-4
(a) The Department may issue permits for the closure of state highways for special events upon terms and conditions relating to the safe and orderly movement of traffic that the Department finds necessary. All applications for special event road closures are contingent upon the concurrence of county governmental authorities if the closure would restrict the use of any county road in the unincorporated area of the county.
(b) If an event calls for closure of a state highway within an incorporated city or town, for which there is no readily accessible alternate route, the city or town shall request Department approval for the closure.
(c) The Department, in issuing permits for the use of state highways, shall not be responsible for the conduct or operation of the permitted activity.
(d) The permit applicant shall agree to indemnify and hold harmless the State against any and all claims, for acts or omissions committed by other than state employees, arising out of any activity for which the permit is issued.
(e) Special event permits will not be issued for the Interstate highway system.
(f) Events on state highways outside corporate limits of a city or town requiring a permit will be allowed only during daylight hours.
(g) The permitting process is not limited to single event applications; provided, that applications specifically address multiple events scheduled throughout the year.
(h) No permit is required for any special event where participants comply with all applicable traffic statutes and highway traffic is not stopped, delayed or detoured.
