3.4 Inspection and maintenance program
To pass the inspection, emissions of in-use vehicles must meet the emission standards for in- use vehicles as shown in Table 6. The current decentralized inspection and maintenance program for in-use vehicles is being criticized for its effectiveness since authorized private inspection centers or garages are also allowed to do repair. The inspection procedure is questionable. The program will be evaluated in the near future and will be improved as necessary to increase its effectiveness.
