The Environmental Protection Department regulates vehicles generating noise by enforcing noise regulations and conducting inspections.
1.Joint inspections and crackdowns on modified motorcycle exhaust pipes are conducted by the Police Departments, Motor Vehicles Office, and the Environmental Protection Department. Environmental inspectors conduct noise tests on stopped vehicles with modifications. If the noise level exceeds the standard, the vehicle owner is prosecuted and given a deadline for improvement according to the law. 2.Upon receiving complaints about noisy motor vehicles from the public, verification notices are issued, and vehicle owners are given a deadline for inspection. If the vehicle exceeds the regulated noise standards or the owner fails to comply with inspection requirements, fines ranging from NT$1,800 to NT$3,600 are imposed. If citizens identify vehicles causing noise disturbances, they can provide details such as time, location, vehicle type, license plate number, and supporting evidence (such as photographs) on the Noisy Vehicle Reporting website for reporting noisy vehicles (including personal information). 3.Vehicles that pass the inspection (with exhaust pipe data uploaded to the cloud database after passing noise tests) are prohibited from using uncertified exhaust pipes that disturb others' living environment. If subsequent inspections or spot checks reveal that vehicles with passing inspections have been modified with exhaust pipes, fines ranging from NT$3,000 to NT$30,000 are imposed according to public announcements, aiming to effectively deter behaviors that disturb public peace caused by modified exhaust pipes.
