Unlike many careers, becoming a commercial truck driver does not require a four-year college degree. In order to prepare to take the CDL exam, most new drivers choose to complete a very short training program with a truck driver training school. This training is then followed by on-the-job training which gives students real-life experience. Keep in mind that the length and depth of training depend upon the state and locale in which the program is offered. That said, most training programs last no longer than six weeks, making it attainable for those that do not have the time or resources to attend traditional college courses.
