On Nov. 13, 2018, an official of the Toll Regulatory Board (TRB) announced in a radio interview that a ban on buses along elevated parts of the Skyway (a 32-km elevated tollway from the Alabang-Zapote Rd. in Muntinlupa to Gil Puyat Ave. in Makati) was being considered because over-speeding buses are a safety hazard along the major expressway. He reassured that the proposal was still being studied and that no decision had yet been made.
