A mechanic is a skilled professional who repairs and maintains vehicles, including cars, trucks, and motorcycles. They diagnose problems, perform routine maintenance, and replace worn-out parts to ensure vehicles operate safely and efficiently. Mechanics often work in garages or auto repair shops and use various tools and equipment to complete their tasks. To become a mechanic, individuals typically undergo training through vocational schools or apprenticeships. They learn about different vehicle systems, such as engines, brakes, and electrical systems. Many mechanics also obtain certifications, such as those from the National Institute for Automotive Service Excellence (ASE), to demonstrate their expertise and enhance their job prospects.
