A Commercial Motor Vehicle is defined as any self propelled or towed vehicle bearing an apportioned plate or having a Gross Vehicle Weight Rating (GVWR) or Gross Combination Weight Rating (GCWR) of 10,001 pounds or more, which is used in commerce on a public highway.  

A Farm Vehicle Driver is a person who drives only a commercial motor vehicle that is controlled and operated by a farmer as a private motor carrier or property, and being used to transport either agricultural products, farm machinery or farm supplies.  A farm vehicle driver is also a person who drives only a commercial motor vehicle that is also not being used in the operation as a for hire motor carrier, not carrying hazardous materials of a type or quantity that requires the commercial motor vehicle to have placards according to the regulations, and being used within 150 miles of the farmer's farm.  

A Farmer is any person who operates a farm or is directly involved in the cultivation of land, crops or livestock, which are owned by that person or are under the direct control of that person. 

A nurse tank meets the definition of a cargo tank. Nurse tanks used in agricultural operations for the transportation of anhydrous ammonia must be repaired by a facility that maintains an 'R' stamp issued by the National Board of Boiler and Pressure Vessel Inspectors (National Board). This 'R' stamp authorizes the facility to perform welded repairs on cargo tanks built to the American Society of Mechanical Engineers (ASME) code. 'Repair' means any welding on a cargo tank wall done to return a cargo tank or a cargo tank motor vehicle to its original design and construction specification, or to a condition prescribed for a later equivalent specification in effect at the time of the repair. Only facilities that have been issued an 'R' stamp by the National Board are authorized to perform repairs to nurse tanks.
