Ensuring the safety and smoothness of road traffic in transports, which by their parameters may cause a special situation in road traffic, is the primary task of the team of workers accompanying overweight and/or oversized vehicles. In order to successfully carry out such an activity, it is necessary not only the appropriate technical equipment but also the knowledge of accompanying staff on the issue of critical points during transport and knowledge of how to prevent the danger in the most appropriate way. For these reasons, there is a need to focus the interest of companies on the course of such transport and to increase the safety of all road users through trained staff to accompany vehicles performing overweight and/or oversized transport.
