One of the major benefits of obtaining a commercial driver license is that drivers have a great deal of flexibility. People that work in factories, offices and other static facilities have little flexibility in terms of where they live. Truck drivers, however, are not under the same types of restrictions. Many companies have no residency requirements for their drivers. What that means is that moving to a new city, or state does not mean having to find a new job. In addition, drivers can choose from full-time, part-time, seasonal, long-haul, short-haul and local jobs.
