1. (a) Unless specifically authorized in writing to do so by the motor carrier under whose authority the commercial motor vehicle is being operated, no driver shall transport any person or permit any person to be transported on any commercial motor vehicle other than a bus.

   1. (1) Employees or other persons assigned to a commercial motor vehicle by a motor carrier;
   2. (2) Any person transported when aid is being rendered in case of an accident or other emergency;
   3. (3) An attendant delegated to care for livestock.
2. (b) This section shall not apply to the operation of commercial motor vehicles controlled and operated by any farmer and used in the transportation of agricultural commodities or products thereof from his/her farm or in the transportation of supplies to his/her farm.
