Notes
Massachusetts requires motor vehicle repair shops to be licensed by the Registry of Motor Vehicles (RMV). Individual technicians working in these shops must also meet registration requirements. Class 1 covers general mechanical repair including diesel. Technicians must pass required exams and demonstrate experience. Verify individual technician vs. shop licensing requirements with the MA RMV.
