Notes
New Jersey requires motor vehicle repair facilities to be licensed by the New Jersey Motor Vehicle Commission (MVC). Technicians performing repairs in these facilities, including diesel engine repair, must work under a licensed facility. The MVC licenses repair facilities in specific categories including diesel engines. Individual mechanic licensing is tied to facility licensing. Verify current individual technician requirements with the NJ MVC.
