The transport is a multifactor open system, which is a subject of many external and internal risks of different types and origins (technical, organisational, human, nature, etc.). The type of the risks is often a factor, which plays a big role in decision how to assess the risk and in our evaluation on whether it is acceptable for us. On the other hand side, the historical development of the different types of transport with their different technical, organisational and geographic aspects, is also an important factor, which contributes to the variety of practices with regards to the management and the evaluation of the risks. Therefore, the role of internationally accepted laws and standards, which ments towards the assessment and the acceptance of the risk, is very important. Such documents are for example the family of international standards IEC 61508, ARP 4753/ED 79, DO-178/ED 12B, DO-254/ED 80, ISO 26262, as well as other international standards and documents. This article aims to present a short overview of the present practices within some types of transport with regards to the criteria for risk acceptance. Presently, at an international level, many of the aspects, related to these criteria do not yet have a solution. From the point of view of the author, this article has the aim to present an objective overview, which would contribute to the discussions and provoke further conversations, analyses and research on the above subject.
