Abstract
One major way of increasing efficiency in production, construction and agriculture industries is to use motor- and tractor-trailers for transportation needs. At the same time, a tractor-trailer is a complex and less maneuverable machine in comparison with a single vehicle. Exceeding the velocity regime, especially in the case of tractor-trailers, leads to a loss of stability during linear motion, on curvilinear sections of the trajectory or in complex traffic conditions. Speed limit is a standard prevention method; however, it does not guarantee any acceptable result. Other ways of resolving this issue have almost exhausted their potential. It should be noted that solving this problem is further complicated by a lack of a unified road-movement theory for tractor-trailers – thus, mainly restrictive measures are used. The authors suggested a hypothesis on possible improvement of tractor-trailer safety by means of increasing their motion stability via upgraded design characteristics of towing tractor-trailer couplers. The higher stability would be achieved by raising the damping factor of transverse oscillations by applying lateral disturbing forces. The authors proposed over 55 technical solutions, all protected by certificates of authorship in engineering, of upgrading the towing couplers and providing the increase of tractor-trailer operation safety in various road conditions.

Summary
One major way of increasing efficiency in production, construction and agriculture industries is to use motor- and tractor-trailers for transportation needs. New energy-saturated wheeled tractors, which come into operation, have higher velocity characteristics (over 80 km/h) and may well compete with motor-trailers on a highway. Published under licence by IOP Publishing Ltd motion stability, maneuverability and others) and design safety do not allow one to use the velocity of tractors to its full potential. Performance characteristics of motor- and tractor-trailers, such as maneuverability and trajectory motion stability, are way below those of a single vehicle, which has negative impact on safety and work environment of drivers. Better active design safety is achieved in particular by improving such a factor as the tractor-trailer stability [1], which would allow to maintain linear motion despite the disturbing forces that provoke skidding or overturning, especially at high speeds. As the number of trailers on the road is a lot less than the number of single vehicles, it really manifests higher danger from tractor-trailers when it comes to road accidents
