Legal basis: Provisions on the Administration of Road Transport Practitioners Article 6 The State implements the qualification examination system for road transport practitioners. Professional qualification is the basic evaluation of the professional quality of road transport practitioners engaged in specific positions. Drivers of commercial road passenger and freight transport and practitioners of road dangerous goods transport must obtain corresponding qualifications before they can engage in corresponding road transport activities. The proportion of motor vehicle maintenance technicians and motor vehicle driver training coaches who have obtained professional qualifications is one of the necessary conditions for relevant operators to obtain motor vehicle maintenance and motor vehicle driver training business licenses according to law.
