Transcript:Keeping the country’s transportation and heavy equipment in motion takes a lot of horsepower… and a crew of highly-skilled technicians and mechanics. Heavy vehicle and mobile equipment service technicians, inspect, maintain, and repair vehicles and machinery used in construction, farming, railways, and road transportation. Diesel service technicians and mechanics service buses and trucks, or repair any type of diesel engine. Many work for trucking companies, wholesale trade firms, and government agencies. Farm equipment mechanics and service technicians repair farm equipment as well as smaller lawn and garden tractors. Most work for dealer repair shops, with seasonal variation in job duties. Mobile heavy equipment mechanics maintain construction and surface mining equipment, such as bulldozers, cranes, graders, and excavators. Most work for government, equipment rental shops, and large construction and mining companies. Rail car repairers keep railroad locomotives, subway cars, and other rolling stock in good repair. They usually work for railroad, public and private transit companies, and for manufacturers. These technicians often lift heavy parts and tools, handle greasy and dirty equipment, and work in awkward positions. While many work indoors in repair shops, some specialize in field service and travel to worksites that may be outdoors, in all types of weather. Service technicians generally work full time, sometimes including evenings or weekends. Overtime is common. Most service technicians have a high school education. Formal training and certificates are increasingly preferred by employers. Certificates usually take 1 to 2 years to earn. Once hired, trainees usually reach full qualification after 3 to 4 years.

What does this information tell me?

Outlook information can tell you whether a career is expected to be in demand in the future—that is, whether there are likely to be job openings if you choose this career. Please note that this does not account for the impacts of the current pandemic. Many occupations are likely to have very different outlooks due to the rapidly changing economy. When new outlook information is developed, it will be reflected here.

Careers can have one of three outlooks:

  • A Bright outlook means new job opportunities are very likely in the future
  • An Average outlook means that a small number of new job opportunities are likely in the future (less than an 8 percent increase)
  • A Below average outlook means new job opportunities are less likely in the future

You can also view local job listings in this field by clicking "Find job openings" above. This can help you see if local businesses are hiring—another way of looking at demand.

What is the source of this information?

This information comes from O*NET Bright Outlook occupations and My Next Move career outlook designations (based on Bureau of Labor Statistics Employment Projections 2022-32). It is only available at a national level, so even if you selected a state, you’ll only see this information for the whole country.
