What do the Z1000 signs mean?

Asked by El_Cadejo (34610points) July 19th, 2009

Ive noticed on a couple different highways have signs that say “Z1000”. They dont seem to have any noticeable significance and appear randomly . Heres the best picture i could find online.

i tried looking it up on google but i keep getting results about kawasakis >_<
