I'm not anti-BF, so don't make me wrong. In fact i like him becaue he demonstrated to us how hardworking government servant he is, but this is where he might go down along the way just because of misusing the pink color.
And so, where does BF legally based his use of Flourescent Pink colors? Is he inventing a new philippine traffic law or were just reapplying our existing ones? Is he a lawmaker? Where is a link and evidence to support his pink crusade?
In the US, the use of pink signs are for Traffic Incident Management:
