The paper is concerned with research of mobility of vehicles, specifically of flotation. The new definition “discrete flotation” is considered. The subject of moving over the snow road surface is considered, especially the crossing of terrain compartments with varying height of snow blanket. The classification of discrete snow obstacles is given separated by the next features: the occurrence of directed anthropogenic factor, the type of formation source, the structure, the degree of shape uniformity of formation source, the stress-strain properties, the composition and the shape of discrete obstacle. The relation describing the shape of snow drifts is given containing the parameters determining the distribution shape, the scale, the area of longitudinal section and the dimension. The relations intended to determine the resistance to moving when crossing the snow drifts and the condition of flotation loss are given.
