None of the truck drivers I know make 6 figures. I suppose it’s possible that owner operators make six figures before dumping at least one of them back into the truck.
I drove commercial truck for three years. First year was over-the-road (OTR) general freight - if it fit in the trailer, I hauled it.
The other two years was dedicated flatbed, hauling shelving for Home Depot.
It is very possible for an independent driver to GROSS a six-figure income. When the costs of the business are added - fuel, insurance maintenance, permits, just to start - that independent driver is NETTING less than the company driver.
I had this conversation once with a brother driver, while I was OTR, and a company driver. He was proud that he owned the rig, no company over his shoulder, etc. so forth. I compared my earning with his. He was mortified to learn that I, as a company driver was taking home more per mile than he was. I paid no fuel, no insurance, no permits; if the truck broke, the company fixed it; and he was on the road for months, while I got home on the average every two weeks.
So yeah, it’s possible to GROSS that kind of income. But the truck’s your business, and you’re working fo rthe truck, not for yourself.
