From a very generalised perspective, it can be said that humans are the weakest link regarding road traffic safety. Researchers have focused on their health status, physical, mental and psychological characteristics, gender and age, etc. They have been exploring the question of whether there are persons who are particularly predisposed to becoming the perpetrators or victims of accidents or catastrophes, posing a direct risk of accidents and catastrophes, or causing road traffic hazards. This paper is focused on the issues related to aggression and anger that drivers experience and so-called road rage. The author identifies and analyses the factors determining such conduct, discussing its causes and behaviour prior to such incidents and considering external conditions. Emphasis is placed on the fact that anger, aggression and rage are often followed by a hazard, resulting in an accident or other road incidents mentioned above. Attempts are made to point to yet unexplored spheres of possibly identifying symptoms that indicate aggression or rage, which have been a neglected issue so far and which could be significant for taking anticipative and preventive measures without risk of penalty. The author asserts that the analysis of criminal cases and the evidence collected in the course of such procedures, including tachograph records, event data recorders, video recordings and surveillance cameras, may constitute materials used by an interdisciplinary team of experts to create an algorithm that allows preventive measures to be undertaken before outbursts of aggression, rage and violence take place. Undoubtedly, it is a cybersecurity-related task, which, by no means, may be associated with an excessive surveillance of behaviour on the roads
