Opportunities for Optimizing the Activities of the Investigator and Expert to Improve the Efficiency of the Investigation of Traffic Accidents

The subject of the study is to improve the interaction between the activities of participants in the investigation of road traffic offences. From the materials of criminal cases, it is clear that quite often the role and place of the forensic examination is unreasonably diminished by the investigator. It happens due to the fact that a large part of the physical evidence collected at the crime scene during the initial inspection of the scene of the incident and containing the necessary amount of investigatively significant information, falls out of the general picture that forms the content of the investigative situation. The most effective interaction of the investigator with the expert is realized only when it is organized from the very beginning of the investigation of the crime event, and hereby covers all stages of the investigation, from the examination of the crime scene, the appointment of the examination, the process of examination, conclusions, and end results of expert research. Gathering evidence and clarifying all the circumstances that contribute to the commission of the crime seems to be the basis for solving practical problems that confront the investigator upon arrival at the scene of an accident. For the full implementation of these tasks, the investigator resorts to the practical assistance of an expert, a specialist who has methods for solving the questions posed to them, the practical possibilities accumulated in the complex of technical and forensic, as well as theoretical support for the production of examinations. To implement the tasks set for the investigator to investigate accidents, the investigator simply needs to assress an expert for competent answers. In turn, the expert is authorized to take expert initiative in the course of the investigation, within the limits of his expert authority, to identify, evaluate and establish the circumstances indicated by the investigator in the case under investigation. Empirical and theoretical research methods, a comprehensive analysis, and other methods of scientific knowledge were used in the process of study. The results of the study made it possible to formulate a set of recommendations aimed at improving the regulatory framework governing the interaction of the investigator and expert
