The functional state of the driver is one of the sources of information about the body readiness to perform tasks. It affects the traffic safety of all participants in this process. The problem acquires significant importance in passenger transportation by route vehicles in difficult traffic conditions. For this, a research of changes in the functional state of the drivers who drove the buses with different performance characteristics on roads in mountainous areas was carried out. This is caused by the fact that such traffic conditions complicate the driver's work. The research results show the influence of the route vehicle characteristics and conditions on the functional state of the driver. The index of activity of the driver's regulatory systems during long work can grow and reach 9 points. In this case, the body is in a state when adaptive and protective mechanisms can not cope with the load and can not react in time to the impact of external factors. Upon processing statistical data of research results, a pattern of change in the index of activity of the driver's regulatory systems depending on the mountain traffic conditions was revealed. Accordingly, the formula for determining the recommended driver's work duration was proposed. Using the influence factors of specific power of the route vehicle and the level of congestion, it is possible to take into account the influence of these factors on the functional state of the driver when developing the driver work schedules.
