Expert characteristics of the highway, allowing to define a condition of a covering, its geometry, visibility, etc., influencing the road accident (RA) mechanism are considered. Road and transport examination is urged to establish all reasons and the conditions promoting studied road accident. Values of flatness of a cloth, standard of geometrical characteristics of the highway, value of a cross bias depending on a covering, requirements to road infrastructure, including installation or reconstruction of signs, drawing a marking are considered. Research of elements of the road was conducted by means of instrument and tool base. Road characteristics are studied: width of the carriageway and roadsides, geometrical and meteorological visibility of a surface of the highway and the counter vehicle, radiuses of curves in the plan and a longitudinal profile, flatness, a roughness and coupling qualities of a covering, level of the contents are expensive (a full or partial schistka of a covering from snow, dirt or frostings), existence or lack of road signs, marking, technical means of the organization of movement.
