OK. So I got the standard fob-off rejection of my informal challenge.
Worth my while continuing this and risking 50%?
The only thing which strikes me is the comment:
"[Temporary suspension signs] have been checked and we can confirm that they are correct and in line with the regulations." Which begs the question what regulations? as AFAIK suspension signs are not defined.
I have applied FOI for the TMO and the suspension request.
