What is the law regarding flying the George Cross from vehicles?
[I hope a contributor from the UK can add to this question]
The George Cross is the highest civilian decoration that can be
awarded by the United Kingdom.
As of 1943, in accordance with the George Cross (Restriction of
Use) Ordinance, it is unlawful to use the George Cross or an
imitation of it or the words George Cross, for the purposes of
trade or business without the authorisation of the Prime
Minister.
However, whether or not its use is restricted to other
decorative uses or display is unknown by this contributor, although
it would seem to follow, that only those to whom it was awarded
would have the authorization to display it.
