Dear PAO,

I recently moved from the province to Metro Manila. On a recent trip using public transportation, I came across a disagreement between a student and a driver regarding seat belt use. As I am unsure of the specific law myself, I didn't get involved. The student was worried the dusty seat belt would stain his white uniform and did not believe that there was a law requiring front seat passengers to wear one. The driver countered that a seat belt law exists. Given this situation, I'd like to confirm: Is there a law mandating seatbelt use for passengers on public transportation in the Philippines?
