An oil truck driver transports crude oil in a tanker truck from an oil field to a secondary facility, where workers can use it as is or process it for future use. In this career, you are a commercial delivery truck driver, so you must have your CDL. Your responsibilities include driving hazardous materials according to the laws and regulations of each state you enter, helping to load and unload oil from your tanker, and keeping accurate trip logs, either on paper or in an electronic logging system. You also have truck maintenance duties.
