To be considered in the transportation industry you must be subject to the DOT rules and regulations :
Per DOT requirements, any driver operating a vehicle with a weight capacity of 10,001 pounds or more, a vehicle transporting 8 or more personnel (including the driver), or a vehicle transporting hazardous material that requires placarding is required to have a driver qualification (DQ) file. This necessary qualification is separate from commercial driver's license (CDL), and the application for each is therefore slightly different.
