Outside of a Harry Potter film , have triple deckers ever been used in

Triple deck road trailers are a major hazard on our roads in windy
weather. *

You mean double deck...

I mean triple deck. The Wilson Tridecker for one, unless the
authorities have seen sense and banned them. The third deck is
obtained by underslinging like a low loader. Thus the lowest floor
nearly touches the road, the roof is 15' 9" above ground and a side
wind has nowhere to escape.

And actually they aren't. I can't recall ever seeing one on its side. I
also drove the very first reefer ones that came to the UK and they were
no worse in high winds than a normal trailer.

Quite a number of tri-deckers have gone over. One I particularly
remember went over on the M6 a good few years ago wiping out a family
of eleven in one hit.
