I don't think plastic equals fake, fiberglass is plastic, just re-inforced plastic.

The font is the bigger issue for me, yours seems to use Arial font, which was invented in 1982.

Totally possible these are legit signs, just a little newer. People that make fake signs do love Arial for some reason though, never understood why they always use Arial.
