Traffic accidents represent a significant safety challenge, and analyses in the Republic of Srpska show that one of the most common driver errors is improper overtaking and turning. These actions require high concentration, assessment of road conditions and correct decision-making, and their improper execution often leads to collision situations. Overtaking, in particular, is a complex action that includes numerous factors such as assessing speed, distance and the reactions of other road users. 

The aim of this paper is to determine, through a temporal-spatial analysis, who and to what extent contributed to the occurrence of a traffic accident in a case where vehicles performed turning and overtaking actions. Special emphasis will be placed on whether these actions were permitted in the specific circumstances, as well as on determining the causal factors that led to the accident. The analysis will be conducted through a review of the traffic and technical expertise of this case, taking into account relevant traffic regulations, technical aspects and the behavior of the participants in the accident. 

The results of this research can contribute to a better understanding of risk factors when performing overtaking and turning actions, and provide guidelines for improving traffic safety, both through improving regulations and by raising driver awareness of the risks associated with these maneuvers.
