What Exactly Are They For, Then?

A sort of funny thing I spotted outside of a garage that maintains buses. Around the corner that's visible in the photo, a door was open and inside were many more of these bright green cones with "DO NOT USE" written on them.

I guess they just got them to be a subject for your photo then. LOL

Well now … what a conundrum! So what’s wrong with them, they look in perfect condition. Perhaps they’re the wrong colour? Interesting photograph!
