The DVLA are sending out letters to all drivers.

Here is what it says!!!

"In order to assist other motorists in identifying potentially dangerous drivers, it's now compulsory for anyone with a lower than average driving ability to display a warning flag.

The flag (comprising of a red cross on a white background) will be attached to the top of at least one door of their vehicle.

For drivers of exceptionally low ability, additional flags are required."

It comes into force this summer apparently.
