This probably won't help the eventual tagging, but the 'unfit for 'wide
/ long vehicles' bit is to do with legislation, both UK & nowadays
European. I think the relevant bit is the 'Construction & Use
Regulations' which lays down the maximum sizes for normal road usage. If
the vehicle exceeds these dimensions (either weight, length, width or
height' then they become an 'abnormal indivisible load', and require
notifications to the police & other specialist departments before they
are allowed to move. You also need special training & a permit / licence
before you can drive one, and may need an escort if it is big enough.
The vehicle is fitted with boards marking it as a 'long vehicle' or wide
In simple terms, the dimensions have been standardised across the EEC,
and if what your driving is big, it will be labelled as such & you will
