Trucking Carriers

Active US trucking and bus carriers with 10 or more power units, from official public data, updated daily: fleet and drivers, operation, operating authority, safety rating, cargo, crashes over 24 months (fatal, injury, tow-away) with the crash rate per 100 power units, and roadside inspections with driver and vehicle out-of-service rates. /trucking/carriers/{carrier} gives one carrier (by carrier number or page name) with its fleet rank and the averages of all carriers, of its state and of all roadside inspections.

The answer is {total, limit, offset, sort, order, filters, data_date, rows, about}. Until the first load is finished it has empty rows and note "Data is being prepared".
