Narrative & sources
Diesel service technicians and mechanics inspect, repair, and overhaul buses, trucks, or any vehicle with a diesel engine.
Diesel service technicians and mechanics usually work in well-ventilated and sometimes noisy repair shops. They occasionally repair vehicles on roadsides or at worksites. Most diesel technicians work full time, and overtime and evening shifts are common.
Although most diesel service technicians and mechanics learn on the job after a high school education, employers are increasingly preferring applicants who have completed postsecondary training programs in diesel engine repair. In addition, industry certification may be important.
The median annual wage for diesel service technicians and mechanics was $60,640 in May 2024.
Employment of diesel service technicians and mechanics is projected to show little or no change from 2024 to 2034.
