It was about five or six years ago that I remember reading about the crack-downs. Seems to me that it went on for a couple of years.The cops over here don't bother us to much, few years ago they had a purge on tinted visors and race cans. The ruling is they won't give tinted visors a B.S. kite mark so this makes them illegal to fit. You can wear sunglasses tho, i ride all the time with a tinted visor and i'd be really unlucky if i got a ticket. Its illegal to sell tinted visors here, so we get them through the internet , and there sent from outside the UK from places like Jersey or Guernsey.
