The article analyses international experience in the use of three-axle road trains with a total length of over 25 m in the field of road freight transport. It considers the main technical and operational characteristics of such vehicles, the conditions for their use, as well as the regulatory and infrastructure restrictions in force in different countries. It analyses approaches to regulating the movement of three-unit road trains in the European Union, Scandinavia, Australia, etc., taking into account requirements for dimensions and weight parameters, routes, road safety and the impact on transport infrastructure. The potential advantages of using road trains of this length in terms of increasing transport efficiency, reducing transport costs and environmental impact are identified, and reservations about possible risks and limitations are highlighted. The results of the analysis can be used to justify the feasibility of further introducing three-unit road trains into international and domestic freight transport, particularly in the context of adapting the national road infrastructure and regulatory framework
