[Suggestion] Not enough detail on vehicle configuration (in particular, in the truck and passenger carrying vehicle category). Need meta data (e.g, what is defined as a ''large truck'' (e.g,. greater than 10,000 lbs GVWR? SUTs and CUTs? or only CUTs?) [Response] 
Vehicle styles are taken from the crash report form. The large truck or bus is defined under Help/Variables used in the data. The definition is: Large Truck/Bus Vehicle Flag ? Indicates whether or not the unit is a commercial bus or a truck with six or more tires (except truck/tractor without trailer.)
