Trucks are not born. We don't have parents. There is no father and mother who taught me how to run on roads. In fact I cannot run on roads without someone with biological parents handling me. Though I cannot do things on my own, but I do carry a lot of power. More powerful than any of the living being with biological parents.
A truck is a complicated piece of machinery. There is a variety of material that is used to make me. I have got steel in me, a lot of steel. This steel might have come from India or UK or god knows from where. Someone Narendra in India or Theresa in UK would have run the plant to make the steel. The steel itself comes from one of the iron ore mines, may be Kiruna Mines. Stefan would have worked to excavate the mines to get the iron ore.
