The article deals with the technique of determining the share of kinetic energy costs for the development of deformations and the speed of the vehicle equivalent to these costs at the technical reconstruction of the accident. The coefficients used in this technique affecting the value of the vehicle speed at the time of collision are studied. The dependence of the calculation results on the choice of this coefficient is determined, and the problem of their refinement for each model of the car is set. The modernization of the rigidity coefficients used in expert practice, considering modern trends in the automotive industry, is highlighted.
