HI JohnoHynes, my wife has had her licence revocked recently due to failing the same field test as yourself an its caused a lot of stress for us, I have said we need to try the route you took. Is there any chance you could e-mail a copy of the letter you sent them so she can work off it . I ask this as we don't want to mess it up. I hope you can help and we would be very cratful if you could. Cheers Tom
