Abstract. The aim of the publication is to present the principles, methods and techniques of testing the condition of vehicle serviceability, management and logistics of operation, where the development of digital technologies is fast and intensive, and users must keep up with the changes and adapt to them. This concerns trends in the logistics of using and servicing vehicles, including operation engineering, logistics in maintaining serviceability, engineering management of serviceability and safety, and all this supported by information technologies. The presented, out of necessity, signal elements of safety, logistics and technical diagnostics as the main problems in maintaining the technical readiness of military vehicles. The practice of operation and legal requirements indicate new trends in the area of maintaining the serviceability of vehicles, shaping modern vehicle maintenance services. The work presents useful concepts and tools that can support further development of safety and maintaining vehicles in readiness.
