What types of vehicles are referred to as motor vehicles?

[DeClara]

Motor vehicles include cars, trailers, trolleybuses, agricultural transport vehicles, motorcycles, motorized tricycles, and transport tractors (including wheeled tractors with trailers), as well as wheeled special-purpose machinery vehicles, but exclude any vehicles operating on tracks. Motor vehicles are driven by their own power devices, have two or more wheels, do not require overhead lines or tracks, and can travel on roads or off-road surfaces. They are primarily used for transporting people, goods, or fulfilling certain specialized work requirements as "vehicles." Vehicle classification is a fundamental aspect of various vehicle standard systems. Different standards have different vehicle classification methods, which may reference each other while also having their own focuses and distinctions. Only by correctly understanding and grasping the basic concepts and applicable scopes of different classification methods, and clarifying the connotations and extensions of specific definitions, can one accurately apply relevant standard clauses in motor vehicle inspection practices, precisely determine vehicle types, and correctly issue inspection conclusions.
