To work as a bus and truck mechanic, you typically need to:

• be at least 18 years old;
• have a high school diploma or equivalent;
• have a commercial driver's license to test drive trucks; and
• complete long-term, on-the-job training.

Education after high school

Some bus and truck mechanics complete formal training programs. Professional-technical schools and two-year colleges offer these programs. In most diesel service technician programs, you get a combination of class instruction and hands-on practice. Programs last between six months and two years. You usually earn an associate degree when you complete a two-year program.

In a diesel service program, you study the latest truck technology. You learn how to service and repair vehicles. You also learn how to understand technical manuals. In addition, you learn to communicate with customers and coworkers.

On-the-job training

Most bus and truck mechanics are trained on the job by an experienced mechanic. You begin by working as a helper. As a helper, you usually clean parts and put fuel in vehicles. As you gain more experience, you work on more complex tasks. During training, you learn to:

• repair and service diesel vehicles;
• service electrical systems; and
• service brake systems.

On-the-job training usually takes three to four years to complete.

Military training

Some branches of the military train people to be mechanics. They offer training in several types of engines, such as boat, auto, and heavy equipment. Training lasts eight to 29 weeks, depending on your specialty. Further training occurs on the job.
