So what does the DPWH say about signs and their installation? The DPWH in their Highway Safety Design Standards (Part 2: Road Signs and Pavement Markings Manual) states the following:

It’s plain and simple and yet we find a proliferation of ads masquerading as signs and entities such as the MMDA and LGUs not properly (or strictly) implementing the provisions of the DPWH manual. It is also sad to see practitioners actively trying (and succeeding) to circumvent this provision in the DPWH manual.
