BAGUIO CITY — Motorists who refuse to comply with Baguio City's campaign against loud mufflers and unauthorized exhaust modifications have no place in the city, Mayor Benjamin Magalong said.

The mayor issued the warning after some apprehended motorists criticized the strict enforcement on social media, claiming authorities lacked consideration.

Magalong said the city government had conducted extensive public information campaigns before launching enforcement operations, adding that violators had ample time to comply.

The crackdown is based on Republic Act 4136, or the Land Transportation and Traffic Code, and Land Transportation Office Memorandum Circular 2020-2240, which prohibit modifications, deletion, or replacement of factory-installed exhaust systems that produce excessive noise. Violators face a P5,000 fine.

To strengthen enforcement, local police stations have been equipped with decibel meters to accurately measure vehicle noise levels during checkpoints. The initiative was developed through consultations with city officials, law enforcement agencies, and motorcycle groups before later expanding to include four-wheel vehicles.

During a previous three-day operation, authorities apprehended 124 motorists. Of these, 44 were cited for loud exhausts, while 80 were penalized for unauthorized vehicle modifications. The operation involved 43 Land Transportation Office-deputized law enforcement personnel.

Before the crackdown, the city launched Oplan DRIVE, an information campaign encouraging motorists to voluntarily comply through coordination with repair shops, transport groups, online advisories, and roadside information banners.

City officials said enforcement will continue as part of efforts to reduce noise pollution and maintain public order.
