I’ve recently had C1&D1 reinstated so I can drive an ambulance. I passed my car test in 1992, so had it automatically added then. It was stripped on my T1 diagnosis in 1998, so I had to reapply. I had to have a GP medical and eye test, then another with my diabetes consultant followed by yet another with the DVLA “independent diabetologist”. Of course I had to have three months worth of at least twice daily readings and be able to account for every dip below 4mmol in that time to the DVLA chap. I keep a small diary and write the reason for any now.
