Everyday on the roads there are traffic accidents where traffic participants suffer more or less harmful consequences. Unfortunately, road traffic safety is only paid attention after traffic accidents, and preventive and repressive measures only bring the results to a shorter period.The main features of the past decade in the area of road transport safety are the increase in the number of traffic accidents and injured traffic participants while the number of deaths is declining. However, despite the decreasing of the most serious consequences of traffic accidents, increasing police actions and raising public awareness of traffic safety issues, the number of traffic accidents and road deaths is still too high. Although the number of deaths on EU roads increased by 0.5% in 2015 compared to 2014, this number has declined considerably compared to 20 years ago. In road traffic in the EU, 26100 people lose their lives, while that figure in 1995 was 64000, which is a a decrease of 59.2%. In this paper, based on historical data, the main causes of traffic accidents will be analyzed and statistical analysis of the number of traffic accidents will be implemented to show the current situation in the Republic of Croatiaand statistical analysis for Lika-senj county. At the end of the work, a comparison with the situation in the European Union is given.
