Found this on one of the motorcycle blogs I follow, thought I should share:
"UK motorcyclists will need to display a front number plate from the end of next month onwards, under a subsection of the revised licensing laws. Motorcyclists will need to apply to the DVLA by the 30th of April and purchase an envelope sized sticker (at a cost of £19.95) which they must then affix to the front of their helmets. The Thames Valley Police Commissioner, Anthony Stansfield was quoted as saying: "UK bikers have been getting away with speeding offenses for far too long", and claiming that 61% of motorcycles caught speeding by traffic control and speed cameras escape fines because of a lack of front number plates. Failure to display a front number plate by 15th June will result in an £1,000 fine, and 3 points on your license"
Be warned!
