I have had type 2 diabetes since 2002. have been on insulin since 2013 hold a hgv licence. until today. Because i filled out there form wrong have had my driving licence revoked. I rang them up and got nowhere. They say you have to test your blood two hours before driving and every two hours whilst driving. I only drive a vehicle under 7.5 tonne and jobs come into our work base at random so its not like a lorry driver or delivery driver, i could be at work doing other things (not driving) for several hours. So the question on the form you fill out said Do you test your blood every two hours from starting work? so because i said no, i have lost my licence. I rang them up and basically they were not interested what i said, the decision had been made and that was the end of it. I find them the most unhelpful people on the planet.
