What Does a Truck Driver Have to do to be Able to Drive a Tractor-Trailer Truck?
Drivers of semi tractor-trailers, big-rigs, 18 wheelers, and commercial vehicles weighing 10,000 pounds or greater are required to qualify and carry a commercial driver’s license, otherwise referred to as a CDL. Truck drivers having a commercial driver’s license may then transport cargo in their tractor-trailer truck in any U.S. state.
