An owner-operator is a self-employed truck driver who owns their own tractor. Instead of driving a company-owned truck for hourly or mileage pay, they run their own business. They are responsible for all their own costs, including truck payments, diesel, maintenance, insurance, and taxes. They make a profit by hauling loads for shippers or leasing their truck to larger fleets.
There are two main business models. Lease-on owner-operators sign a contract to haul exclusively for a large carrier, using that carrier's DOT authority and cargo dispatch. Independent owner-operators run under their own MC authority, booking their own loads directly with brokers and shippers. While it offers higher earning potential, it carries high financial risk when diesel prices rise or freight rates drop.
