The ones used on construction equipment and safety signs, and fictional things that are supposed to look industrial?
Heh, missed the edit window.
This is the first picture I can think of with it. Not the best example (the bands are usually shorter in my experience) but the pattern on the sides of this toy tank.
Hubby (firefighter) calls it caution tape.
Ah, okay, thanks. I would not have thought of calling it that, because I’m used to caution tape having “do not cross” or some other phrase on it, but it’d probably work for most people.
Caution Stripes seems to be a common name for them.
I’ve only very rarely heard them referred to at all, but when I have they’ve been mentioned as either “diagonal stripes”, “warning stripes” or more improperly as “chevrons”. This last one is improper because a chevron would actually be a < or > arrow shape instead of a single line. The terminology comes from signs placed on curves. They are known as chevron signs.
As for the name “diagonal stripes”, most civil engineers are pretty boring.
