they are named wombles in the road industry
we have them stationed in our yard.
always 2 up (1 good at letters,1 good at numbers)
they have no power whatsoever.
as for the stop and direct traffic,close lanes etc. bollocks!
they are controlled by ncc,nrc
basically control centres who have people with the power to command closures etc.
had many a run in with them over unsafe practices etc
TOSSERS
