Phæng I belive is the Danish word for danger or something like that, most Danish trucks have it stuck on the wheel arch.
It means trailer passing Neil,to advise people to wait for the whole lot to go past before they pull out.

Nice one Keith, thanks for that. I guess the Danish guy who told me it meant danger had a little problem with the translation. 
cheers lads for all the replys
i must write them all down for reference
as most of the plates are austrian,why have uk car transporters got some on,macfarlanes scanias(they only go to germany,just over the border from venlo),edwardss fm`s(kw should know this one).they seem to be getting very popular.i must admit they brighten the fronts up if nowt else
i wonder if they would look good on an asda fm

I think a lot of manufacturers fit the low noise bits and pieces as a matter of course.It’s probably cost efficient to fit it to all the trucks on the production line,rather than it being a special order as it used to be.
