Training in HTC’s Medium/Heavy Truck Technology program gives you a head start on a career as a technician in the trucking industry. That’s because you divide your learning time between college courses in the classroom and skill development through paid internships at truck repair companies. You will learn about electrical and electronic systems, steering and suspension, air and hydraulic ABS brake systems and vehicle maintenance. Plus, you will perform diesel engine troubleshooting, overhaul procedures and tune-ups on both mechanical and electronic engines. Then add in clutch, transmission, and drive axle diagnosis, repair and overhaul along with preventive maintenance procedures. It’s a blend of classroom theory, shop demonstrations, and hands-on skill development that prepares you for success on the job.

Entry Requirements

Students entering the Medium/Heavy Truck Technology program must be eligible to obtain a CDL (Commercial Drivers License) and be able to pass a DOT (Department of Transportation) physical, drug screening, and background check as a condition of employment for the internship portion of the program.

People in this career frequently:

  • Use hands to handle, control, or feel objects, tools, or controls.
  • Stand for long periods of time.
  • Bend or twist their body.
  • Repeat the same movements.
  • Walk or run for long periods of time.
  • Kneel, stoop, crouch, or crawl.

It is important for people in this career to be able to:

  • Make quick, precise adjustments to machine controls.
  • Hold the arm and hand in one position or hold the hand steady while moving the arm.
  • Use fingers or hands to grasp, move, or assemble very small objects.
  • Move two or more limbs together (for example, two arms, two legs, or one leg and one arm) while remaining in place.
  • See details of objects that are less than a few feet away.
  • Hear sounds and recognize the difference between them.

Work Environment

Physical Work Conditions:

  • Usually work indoors. May occasionally repair trucks on the road.
  • Sometimes work with hazardous equipment, tools, situations, and conditions. The chance of injury is reduced when mechanics follow safety rules.
  • Occasionally wear uniforms.
  • Work inside various types of buses and trucks. Often test drive them before, during, and after repairs.
  • Often must work in extremely bright or dim lighting.
  • Are regularly exposed to contaminants. As a result, they often wear protective or safety gear. 

Job Outlook

Employment of diesel mechanics is closely tied to the trucking industry. Trucks are being used more to carry goods locally and between cities. Since diesel engines usually last longer than gasoline engines and save companies money, companies are expected to buy more diesel trucks. This increase in the use of diesel trucks will increase the number of jobs for diesel mechanics.

Demand for bus and truck mechanics may also be increased due to environmental regulations. Mechanics will be needed to retrofit and modernize existing vehicles.

This career attracts many people because of the high wages and the challenging work. Opportunities are good for those who have attended formal training programs. Those who have not attended these programs may have tougher competition for entry-level jobs.

The economy has little effect on the diesel repair business because companies need working trucks.
