What is a trailer mechanic?

As a trailer mechanic, you diagnose and repair mechanical and electrical issues in large vehicles, such as semi-trucks and tractor-trailers. Your primary responsibility is the maintenance and repair of heavy trucks. Your job duties are to identify problems, replace parts, and handle repairs to electrical systems, hydraulics, and brake systems. You report to a manager who ensures that repairs are completed to company standards. Another aspect of the job is answering client inquiries, so people skills are helpful. The qualifications for a career as a trailer mechanic are a diploma or certificate in mechanics and heavy truck technology.
