What vehicles are included in motor vehicles?

[PaulDella]

Motor vehicles, abbreviated as "motor vehicles," are wheeled "vehicles" driven or towed by their own power devices, without the need for tracks, and can travel on land. In China, they generally refer to vehicles used on roads for passenger transport, transporting goods, or performing specialized tasks. These 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. However, they do not include any vehicles that operate 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 non-road surfaces. They are primarily used for transporting people, goods, or meeting certain specialized work requirements.
