%X The increase in traffic safety and the design of safer roads includes installation of guardrail systems on separate road segments as part of the highway infrastructure for withholding the vehicle back on the road. In cases when there are no authorities to monitor the highway infrastructure or the EU regulations are taken as a recommendation but no obligation, situation like the bad restrain systems installation can occur. One example of not proper installation of the guardrails is misaligning the bolt holes for the fastener connection between the segments usually resulting in removing them. The aim of this study is to examine the influence of missing fastener sets between the guardrail segments. For model initial input and its validation parameters data from real-life accident were taken. This accident was fatal for the passenger¡¯s life.
