Although traffic is a precondition for the overall social development, it is at the same time a global problem, worldwide and as such it is associated with numerous negative effects from various segments, in addition to the suffering of traffic participants. In order to improve traffic safety on the roads, the police around the world, including Serbia, are constantly trying to apply all the more advanced technologies, which have a wide application in terms of improving safety in general.In this paper, we presented the development of the application of certain technical means within the Ministry of the Interior of Serbia of importance for traffic safety in Serbia, pointed out the importance of a unified information system and automatic number plate recognition. The state of traffic safety on the roads in Serbia and in Valjevo in the period 2014-2018 is given. The aim of the author was to determine how the introduction of specific measure - the use of camera - reflects on the work of the police, whether the number of registered violations is on the increase, or how it reflects on the work of the Misdemeanour Court in Valjevo in terms of increasing the number of convictions and specific sanctions. On the example of the city of Valjevo, through official data over a period of 10 years, we presented the importance of information and communication technologies in detecting two very common traffic violations in the city and sanctioning those violations by the competent Misdemeanour Court. The difference in terms of the number of detected and then sanctioned violations in the period before the start of the use of information and communication technologies in the period 2010-2014 and afterwards, 2015-2019, speaks more than clearly about the importance of wider use of these tools, both in cities but also outside the settlements, on the open road. All this is in the function of increasing traffic safety on the roads in Valjevo and safety in general, because the cameras are becoming increasingly important as they are used to detect the perpetrators of and prove various crimes.
