The techniques used have been the documentary analysis of five police reports of reconstruction in traffic accidents and the interview of five specialists, whose selection criteria have been based on their specialty and field of action, for which reason, they have been part of the sample, two experts specialized in traffic accidents from the Traffic Accident Prevention and Investigation Unit – UPIAT Cusco; an expert in traffic accidents from the PNP Echarati Police Station; and two magistrates of the Judiciary specializing in criminal law, which allows us to show a high level of reliability for the results found. From the results of the present investigation, it has been possible to establish that the reconstruction of traffic accidents is very important to establish the criminal responsibility of the defendants; however, due to the lack of preparation of the intervening police officers, an adequate treatment of the evidence found in the event is not carried out; in the same way, a perpetuation of the transit event is not carried out that prevents the alteration of the scene until the arrival of the experts; consequently, the phases of the transit event are not determined; what causes, the loss of evidence; which causes the reconstruction to be incomplete and historical.
