i had my 7.5ton removed when i notified them last yeat, at the time i owned 3 fire engines all over 3.5 ton
obviously i can no longer drive them, i have sold 1, still have 2, i intend to try and get my licence back
from what i understand, you complete the form, have a medical with a doctor, if the dvla accept that, you then need a medical with a diabetic consultant, and iff all is ok the DVLA will issue a licence that lasts for 1 year.. then i believe you will need a yearly menu to retain the licence
so you have to consider this extra cost, also i dont think it would take much for them to remove your licence
ie, 1 disabling hypo in charge of a vehicle or not will be enough to remove your licence
any signs or retinopathy or neuropathy will also remove your licence
i am yet trying to decide if its worth the hassle
