Matagal nang pwedeng kumanan kahit red. This was done during the fuel crisis of the 70's to save fuel (rather than idle waiting for the light). Of course people who are on the green have the right of way, you just have to merge carefully.

Hindi na lang pwede kumanan kung may sign explicitly saying or or kung nasa Makati ka (kahit ata umutot bawal dun, ingat ka sa MAPSA).
