At risk of trying to teach all you grannies to suck eggs, the first thing that any new T2 recruits to the insulin dependant, pancreatically challenged horde has to do, is make sure they notify the DLA. This usually means having to renew your licence every three years, and having it restricted to vehicles not exceeding 3.5 tonnes gross weight. Sadly, this means that when I come up on the lottery and win zillions of pounds, I won’t be able to buy the biggest motorhome in the world.
I guess the problem of even obtaining a licence is much more complicated for T1s, especially if prone to frequent hypos. Life is, as they say, a bitch!
