Scope and content
Road signs, for the DFPA. These "Slow" road signs made of different materials will undergo rigorous testing over the next couple of months. The signs are constructed of plywood, overlaid plywood, steel, aluminum and fiberglass. They will be rigorously tested for their ability to stand up to direct hits, gunshots and wear and tear. They will be tested for legibility in the daylight as well as at nighttime. The testing was ordered and recorded by the Douglas Fir Plywood Association.
