Drivers of heavy trucks and tractor-trailer rigs
Truck driving employs more than 3 million people, making it one of the largest occupations. A commercial driver's license is the most important qualification for most of these jobs. Most prospective truck drivers take driver-training courses at a technical or vocational school to prepare for commercial driver's license tests.
Drivers are typically responsible for picking up and delivering freight and handle loading and unloading too. They must follow driving laws, keep logs of their activities and make sure their equipment is in good condition. Heavy truck and tractor-trailer drivers are mostly long-haul drivers, delivering goods over routes that may span several states.
Expected growth rate: 21 percent.
