Introduction. In the course of their professional activities, traffic police inspectors of State Road Safety Inspectorate (SRSI) are exposed to harmful working conditions. The aim of study is to provide scientific justification for the periods of service of inspectors that are important for the diagnosis of early signs of professionally caused diseases. Materials and methods. The study was carried out in a group of traffic police inspectors of the traffic police in accordance with the ethical standards set forth in the Declaration of Helsinki, 1975 (with additions, 1983), a positive conclusion of the ethical committee. The age of the traffic police officers was 24-50 years old, the experience was 1-19 years (average values 34±0.46 and 8.21±0.40 years). Results. In the course of the study, a class of working conditions was determined-3.4. low-level traffic police officers showed signs of disadaptation, a high risk of morbidity with temporary disability and professionally caused pathology of the cardiovascular, musculoskeletal, nervous, endocrine, and digestive systems. Conclusions. It is advisable to conduct an in-depth preventive medical examination of inspectors after 1-2 years of service. The first 4 years of service are important for preventive measures.

Road safety depends on several factors associated with the vehicle, to the infrastructure, as well as to the environment and experience of vehicle drivers. Concerning the vehicle factors influencing the safety level of an infrastructure, it has been shown that the dynamic interaction between the carried liquid cargo and the vehicle influences the operational safety limits of the vehicle. A combination of vehicle and infrastructure factors converge when a vehicle carrying liquid cargo at a partial fill level performs a braking maneuver along a curved road segment. Such a maneuver involves both longitudinal and lateral load transfers that potentially affect both the braking efficiency and the lateral stability of the vehicle. In this paper, a series of models are set together to simulate the effects of a sloshing cargo on the braking efficiency and load transfer rate of a partially filled road tanker. The model assumes the superposition of the roll and pitch independent responses, while the vehicle is equipped with Anti-lock braking System brakes (ABS) in the four wheels. Results suggest that cargo sloshing can affect the performance of the vehicle on the order of 2% to 9%, as a function of the performance measure considered. A dedicated ABS system could be considered to cope with such diminished performance.
