technical matters
Whether you can drive a truck in Australia with a college degree is not a question of academic qualifications, but a technical question.
Driver's license requirements
Generally speaking, your driver's license meets the requirements of driving a truck and has little to do with your education.
High academic qualifications do not mean good skills.
After all, you may not be able to drive if you can read, but you are just a rookie in theory. Compared with the old drivers who have been driving trucks for 20 years, experience and technology are scum.
Old drivers are irreplaceable.
But this is the trend of the industry. Young drivers in the future will definitely go through a series of professional training, and old drivers will eventually be eliminated.
