+= General
+
+A vehicle is any machine that moves on land and is either self-propelled or attached to a self-propelled machine.
+Trailers or train wagons are considered separate vehicles.
+However, permanently attached parts, such as the front and rear of an articulated bus are considered a single vehicle.
+The vehicle class contains all land vehicles including wheeled or tracked vehicles.
+In this version of the standard, only wheeled vehicles are considered.
+
+The vehicle 3D geometry is generically structured into the node structure defined in the next section.
+The structure starts with a Root node as a parent to all other nodes in the structure
+A separation of vehicle parts into different groups enables movement or animation of parts, such as wheels and doors, positioning external light sources in a simulation and many other use-cases.
+Each node is an empty node representing the coordinate origin of the contained geometry.
+Meshes are to be placed in the corresponding group node.
+Not all node have to be present in every vehicle 3D model, as not all vehicle have parts to fit all groups.
+Additional group nodes may be added to facilitate additional use-cases, but they shall be integrated into the general structure of external/internal and static/dynamic groups and follow the naming convention.
