Reserved seats for the PWD in public utility jeepneys

PB251004
I just saw this sticker sign posted on the wall of a public utility jeepney here in Lingayen, Pangasinan, and its a sign at the end seat of the jeepney, that seat is reserved for persons with disability.

is this applied also in Manila ? I haven't seen this sticker before in our PUJ in Manila.

btw, its a great idea that they have this kind of special seats for PWD
