IV. Processing procedures after reporting

Information from reports received through all channels will be entered into the computer by each environmental protection bureau. After checking records of the vehicle on the computer, the environmental protection bureau responsible for the area in which the vehicle owner's registered residence is located will contact the owner to take the vehicle to a designated vehicle inspection site for inspection. The vehicle owner is subject to prosecution if he or she fails to take the vehicle in for inspection by the deadline or if the vehicle fails to pass inspection. Informants can inquire about ongoing cases and the results via telephone or on our website. Informants who report vehicles that subsegently fail inspection will receive a reward. Please take advantage of this service and let us work together to protect our environment.
