Mobile Machinery Registration

Mobile Machinery Definition

According to Wyoming Statue 31-18-203, mobile machinery is defined as "heavy equipment, except shop or hand tools, which is self propelled, towed or hauled and used primarily in construction and maintenance of roads, bridges, ditches, buildings, or land reclamation."

Mobile Machinery Registration Requirements

The Statute also states that "no mobile machinery shall be operated in this state, whether or not upon the public highways of this state, unless registered under this division.” 

If operating mobile machinery in Teton County you must register your equipment with a mobile machinery sticker, purchased at the office of the County Treasurer. Wyoming contractors are required to list all such equipment upon the tax rolls through the Assessor's Office, as well as an annual purchase of a mobile machinery sticker. Out of state contractors may obtain registration for any period of less than 12 months. All machinery brought into the state must be registered. Exemptions apply only to demonstrate the operation of equipment to prospective buyers, not to exceed a period of 7 calendar days. Contact the County Treasurer for an application form.
