Visibility at intersections in road traffic plays a key role in ensuring the safety and efficiency of the traffic flow. Insufficient visibility at intersections can significantly increase the risk of traffic ac- cidents. This paper investigates the importance of visibility at intersections and its impact on the safe merging of vehicles into traffic. The state of visibility at intersections in the city of Banja Luka is analyzed in order to identify factors that lead to a lack of visibility. Research results are presented that indicate insufficient visibility at certain intersections, which can lead to an increased risk of traffic accidents. Recommendations and opportunities for improving visibility at intersections are also discussed, includ- ing proper placement of traffic signs, signage and removal of obstructions that impede visibility. The importance of driver awareness of the importance of visibility and timely reaction at intersections is emphasized. This paper provides insight into the problem of lack of visibility at intersections and high- lights the need to take measures to improve road traffic safety.
