Some may not be aware of this recently issued Dept. of Transport Warning:
In order to assist other motorists in identifying potentially dangerous drivers, it is now compulsory for anyone in England who possesses a lower-than-average intellect to display a warning flag; this warning is in the form of a red cross on a white background, which must be attached to the top of at least one door on their vehicle.
For drivers of exceptionally low intelligence, additional flags are required.
