While creating all-terrain vehicles (A TVs) for off road operation, peculiarities of natural climatic conditions especially ones of the far Northern areas where the subsoil is permafrost are often ignored. One of the most common human interferences in the nature of the North is damage to vegetative cover by transport vehicles in the summer time, resulting in thermokarst formation. More than 70% of top-soil cover destruction of the tundra ecosystem is caused by the existing ATVs. The regeneration of the destroyed soil will take decades and even hundreds of years. The issue of ecological balance conservation is closely related to the well-being of 26 native peoples of the North. The contradiction between the transport exploitation of the far North and the necessity to conserve the ecoregions must be solved by creating on-land all-terrain motor vehicles with the reduced impact on the bearing surface. The current stage of development of all-terrain vehicles and, in particular, wheeled vehicles intended for use in severe road conditions can be characterized by a variety of their types and lay-out solutions and, in particular, by different steering arrangements. The choice of the steering arrangement for transport machines designed for applications on soft soils must be made by consideration minimized negative impacts on the bearing surface, providing the tangential stresses in the contact of the wheel with the soil do not exceed the soil resilience values. Therefore, the assessment criteria of curvilinear motion of such ATVs can be the minimized tractive forces necessary to perform a turn. From the standpoint of energy consumed by turning and impact on the bearing surface, the wheel steering arrangement can be regarded as the most favourable, and the worst arrangement is differential.
