The combination of scales of the MMPI for this prole with the increased values of the scales Hs, D and Si indicates a tendency to slow reactions, thinking rigidity, obstinacy and petulance. The high values of the factors A and Pt and the low values of the factors Sf and R testify to lack of self-condence, passivity, angst and the weakness of will qualities. Even the persons with wide driving experience with such a combination of scales make mistakes if their profession deals with driving, be it a plane or a car [13; 10; 14].Fig. 1.

Personality prole of the drivers who have repeatedly committed offenses when driving.At the same time it should be noted that in some cases a different level of expressiveness of scales of the MMPI with the same type of tendency of values is observed in the persons working without violations. To make a quantitative assessment of dependence of success of activity of the person on the degree of expressiveness of these or those scales of the MMPI, a multiple correlation analysis method has been used. The highest level of interrelation of success of activity of drivers is noted: with the scale D - a tendency towards depression, Hs - a tendency towards hypochondria, Pt - a tendency towards psychasthenia. The highest coefficient of interrelation of success of motor vehicle driving for the scale D (r =-0.34). This scale estimates the presence of symptoms of depression in the examined person which is shown in self-dissatisfaction, pessimism, depression and mental block. In such persons (with high values on this scale) inclinations, motives and will activity are sharply lowered, their behavior is characterized by slowness of reactions, lack of initiative and fast fatigue. The analysis of interrelation of indicators of success of driving and the degree of expressiveness of psychophysiological and personal qualities can be used in the professional selection of drivers and when training in driving schools. In particular, a possibility to determine the professional suitability of motor vehicle drivers according to the indicators of functional agility and strength of nervous processes, of the level of development of psychophysiological functions, according to the degree of expressiveness of a number of personal qualities has been shown.Thus, the study performed by us allows to estimate the efficiency and reliability of the modelled and real activity of motor vehicle drivers on the basis of a complex of research works and their separate trends concerning the assessment, diagnostics and prediction of psychophysiological opportunities (reserves) at all the stages of professional cycle, particular persons and various categories of personnel for the optimum and effective control of states of professional activity, traffic safety and the health of workers
