An entry-level truck driver is a student driver who is still mastering the skills of being on the road with a large commercial truck. Driving a commercial truck differs substantially from driving a car, so you need a Commercial Driver’s License (CDL) to drive a truck legally. When you get a job as an entry-level driver, you receive on-the-job training from a mentor who helps with fine-tuning your driving skills and other road habits in preparation for getting a Class A CDL. You need this license before you can drive solo and transport cargo along a designated route. At this level, your responsibilities primarily revolve around learning, but your mentor may assign you other duties as well.
