Where does it say that it is illegal to ride with the flip-front up? Nowhere as far as I can find. I have searched all over for something definitive as laid down by the law, and there is nothing, just loads of layman-level discussion. True, you'd be daft to have it up much over 30mph (or whatever) 'cause the wind is gonna try and rip your head off, but law? No, not as far as I can see. As said, if you know better, PLEASE QUOTE SOURCE.

You won't find anything in the law says its illegal to ride with the flip "flipped", because that in itself isn't illegal. The lid, however, has to meet a set of criteria to get its BS / CE standard mark. The majority of lids are only tested with the flip down, in effect as a full face lid, to get their stamp of approval. So if you ride with it up, then you're not wearing a legal helmet. More and more lids are now starting to get tested both as a full face and a open face (and to do so, they must have the secure latch that someone mentioned), and these fellas you can ride with it up or down, as it has both certifications.

(and others have told me that the chin-bar itself is not crash-tested at all),

I believe that to be complete garbage - AIUI, the chin bar has to take the same test as a standard full face

And agreed, a copper telling you so is not gonna be enough - where is HIS source? Coppers do not know everything there is to know about the law.

Indeedy they do not  :lol :lol
